Trim v2: clarify bug-fix/feature guidance; n=5 experiment
Rewrite the 'not behavior-preserving' escalate bullet so an explicitly requested bug fix or feature is completed via normal development (not refused / 'nothing to change'), addressing the one scenario where v1 regressed. Bump experiment runs 3->5 to tighten the aggregate CI. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: 3c9f9823-7f2f-4f7d-9d1b-f2b9e7a20c60 |

Add csharp-refactoring-trim variant + 3-arm experiment (eval study)
Trim study for PR #873: csharp-refactoring-trim is a ~30% shorter rewrite of csharp-refactoring (drops When-to-use/Inputs/Outputs boilerplate + verbose LSP launch prose, compresses the dbc-overlapping hazards section) while preserving every rubric-rewarded behavior. Adds a 'trimmed' experiment arm and bumps runs to 3 so CI generates baseline/skilled/trimmed trajectories for local cross-family re-judging. Eval-only scratch branch; not part of the PR.

Add vally evals + cost-trim for dotnet refactoring/breaking-change skills
CI-only eval branch (NOT part of PR #873). Carries the uncommitted cost-trim + PR-comment fix on both SKILL.md, the eval.yaml rubric re-alignment, and two new eval.vally.yaml specs so the vally CI can evaluate whether the current skill content helps before merging.

Add automated per-plugin versioning (NBGV) with /version-bump + weekly backstop (#813)
* Add automated per-plugin versioning (NBGV) with /version-bump + weekly backstop WHY Tools that surface skills (Copilot CLI, Claude Code, Codex, Cursor) read a plugin's version directly from its checked-in manifest. With no versioning discipline, a plugin's behavior can change while its advertised version stays flat, so clients never learn to re-pull, and there is no human-readable signal of what changed. We want correct, current versions in the repo with minimal manual work and without bloating the marketplace clone. WHAT - Per-plugin semantic versioning via Nerdbank.GitVersioning (NBGV). Each plugin owns a version.json whose pathFilters exclude the generated manifests and the version.json itself, so version height tracks real content changes only. - The computed version is materialized into the checked-in manifests (plugin.json and .codex-plugin/plugin.json) so every consumer reads a current value with no build step on their side. - eng/version/Sync-PluginVersions.ps1 is the single workhorse. It resolves the set of changed plugins from a git diff, computes each version with nbgv (predicting the squash-merge height for PRs), and either reports or stamps. AUTOMATIONS (two, low-touch by design) - /version-bump: an admin/maintainer comments the command on a PR and the affected plugins are stamped on the PR branch. Gated on collaborator permission (admin/write/maintain); forks are rejected before any privileged step. No other PRs are auto-modified. - weekly-version-sync: a Monday backstop (and workflow_dispatch) that stamps any drift on main, opens/updates a single bot PR, and explains the per-plugin reason. This self-heals anything that merged without a bump. We deliberately did NOT auto-edit contributor PRs or add a noisy advisory comment bot; maintainers stay in control and the signal stays clean. SECURITY (multi-model adversarial review: GPT-5.5 + Gemini 3.1 Pro) - Supply chain (High, both models): dotnet tool restore would have honored a nuget.config authored in the PR tree, letting an attacker remap the nbgv package source to a malicious feed and run code in the privileged contents:write context. Mitigated with a trusted eng/version/nuget.config (clear + nuget.org-only + packageSourceMapping), overlaid from main and used via --configfile so PR-supplied configs are ignored. No nuget.config is tracked in the repo today, so this path was genuinely exploitable. - TOCTOU (Medium): /version-bump now checks out the authorized head SHA rather than the mutable branch name; a racing push fails non-fast-forward, which is the safe outcome. - Injection: Set-ManifestVersion uses a MatchEvaluator (not a replacement string) so a "$"-bearing version cannot re-expand, plus a strict major.minor.patch guard that throws on a malformed base, leaving manifests untouched. - A base-only version.json bump (0.1 -> 0.2) is correctly detected and stamped. VERIFIED End-to-end against a real NBGV git harness: content-scoped predict, base-only bump -> x.y.0, docs-only -> [], weekly drift stamping, malformed-base guard, and --configfile restore (exit 0). actionlint passes on both workflows. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address Copilot review feedback - Add missing plugins/dotnet-test-migration/version.json so it participates in versioning (it was the only plugin without one; manifests are at 0.1.0). - CONTRIBUTING: the two manifests are not byte-identical; say the version is duplicated across two manifest files instead. - weekly-version-sync: include version.json in commit attribution so a base-only bump is explained rather than showing 'no attributable commits'. - Get-NbgvInfo: capture nbgv stderr and include it in the thrown error so CI failures are diagnosable, while keeping stdout clean for JSON parsing.

dotnet-test: reduce assertion-quality over-structuring on small suites (#865)
Scale report depth to suite size so a tiny test file gets a focused, direct answer instead of a padded multi-section dashboard. Preserves full-template behavior for substantial suites and keeps all rubric-relevant substance (assertion-free/trivial identification, quality verdict, concrete recommendations).

dotnet-test: make code-testing agent tools Claude Code-compatible + add cross-host portability check (#856)
* dotnet-test: make code-testing agent tools declarations Claude Code-compatible PR #847 added `tools: ["agent", "skill", "read", "search", "edit", "execute"]` to the code-testing-* agents to enable VS Code / Copilot CLI subagent fan-out. Those lowercase aliases map to real tools in VS Code and the Copilot CLI, but Claude Code matches `tools:` against its own vocabulary (Task, Skill, Read, Glob, Grep, Edit, Write, Bash). None of the aliases matched, so when these agents are loaded into Claude Code via --plugin-dir and selected with `claude --agent`, the agent was granted ZERO tools. A tool-less model asked to generate tests emits a textual <tool_call> block and exits after one turn, producing no file changes. Append the Claude Code tool names to each agent's `tools:` list so the same declaration works across all three runtimes (each honors the names it knows and ignores the foreign ones): - Orchestrators (generator, implementer): add Task, Skill, Read, Glob, Grep, Edit, Write, Bash (Task is the Claude Code equivalent of the `agent` fan-out tool). - Workers (researcher, planner, builder, tester, fixer, linter): add Skill, Read, Glob, Grep, Edit, Write, Bash. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * skill-validator: complete built-in tools + add cross-host tool portability check Two related follow-ups to the agent tools fix: 1. Address the skill-check review feedback. The validator's BuiltInTools set was missing three legitimate host tool spellings that are not case-insensitive matches of existing entries, so they were flagged as non-built-in: - "write" — Claude Code file-creation tool (Copilot CLI / VS Code: "create") - "agent" — Copilot CLI / VS Code subagent fan-out tool (Claude Code: "task") - "execute" — Copilot CLI / VS Code run-command tool (Claude Code: "bash") "agent" and "execute" were already flagged before this branch (introduced by the fan-out PR); adding them to BuiltInTools clears the pre-existing warnings. 2. Add a cross-host tool portability check (CheckAgentToolPortability) so an agent that declares a capability for only one host is flagged. Tool names are matched case-sensitively (hosts resolve tools by exact spelling), so an agent that lists e.g. only "edit" (Copilot / VS Code) without "Edit"/"Write" (Claude Code) is reported as working on one host and silently tool-less on the other. Findings are advisory (do not fail CI) and allowlistable via "agent-tool-portability:AGENT:capability". Wired into the agents loop in CheckCommand and covered by unit tests. Also make the one existing single-host agent (optimizing-dotnet-performance) portable by adding its Claude Code tool spellings, so the new check reports a clean tree.

dotnet-test: raise timeouts for chronic-timeout eval scenarios (#850)
Several dotnet-test eval scenarios repeatedly hit their wall-clock timeout in the evaluation dashboard (skilled + plugin arms), producing empty output and failing all assertions. Increase per-scenario timeouts for the ones that timed out most often across recent runs: - writing-mstest-tests: 'Write unit tests for a service class', 'Write data-driven tests for a calculator', 'Use string assertions for format validation' 180->360; 'Use comparison assertions for boundary testing' 120->240 - coverage-analysis: 'Coverage plateau diagnosis', 'Project-wide coverage analysis with existing Cobertura data' 300->480 - test-gap-analysis: 'Decline request to write new tests from scratch' 120->300; 'Acknowledge well-tested code with few surviving mutations' 300->420 - run-tests: 'Filter xUnit v3 tests by trait on MTP', 'Filter xUnit v3 tests by class pattern and trait using query filter language' 120->240 Per eng/skill-validator/src/docs/InvestigatingResults.md, timeouts are the highest-priority failure mode; code-generation scenarios often need 360s.

Consolidate dotnet-test-frameworks into test-analysis-extensions (#851)
* Consolidate dotnet-test-frameworks into test-analysis-extensions Remove the orphaned dotnet-test-frameworks reference skill, whose content was a duplicate subset of test-analysis-extensions/extensions/dotnet.md. Nothing actually loaded it. Redirect the remaining references and drop its eval tests. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Make exp-test-maintainability Step 1 self-contained and fix activation Address PR review: exp-test-maintainability (dotnet-experimental plugin) must not point at test-analysis-extensions (dotnet-test plugin) — inline the .NET framework markers instead. Also strengthen the description/When-to-Use triggers so the 'each new case needs a whole new method / suggest a better structure' scenario reliably activates the skill instead of routing to a test-writing skill. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Revert exp-test-maintainability description broadening; keep self-contained markers The description broadening regressed activation (3/4 -> 0/4 across a variance-dominated single eval run, CV up to 924%). Description is the activation lever, so restore the original wording and keep only the review-comment fix (inlined .NET framework markers in Step 1). Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Fix scenario 1 eval: use project fixture so the skill activates Scenario 1 pasted a self-contained snippet inline and asked to 'suggest a better structure', which the base model answers directly without loading the skill -> NOT ACTIVATED with no headroom. Convert it to the project-fixture pattern used by the activating scenarios (3 & 4): move the repetitive InputValidatorTests into a Validation.Tests fixture and ask the model to analyze the project. Mirror the change in eval.vally.yaml. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Fix scenario 2 eval: use project fixture so the skill activates Scenario 2 also pasted a self-contained snippet inline (well-maintained Auth.Tests) and asked to 'review these tests', which the base model handles without loading the skill. Convert to the project-fixture pattern used by the activating scenarios; add fixtures/well-maintained/Auth.Tests. Mirror in eval.vally.yaml. All four scenarios now reference a project on disk. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Add reject_tools to exp-test-maintainability evals to create headroom All four scenarios scored NOT ACTIVATED / no-headroom (#8 in InvestigatingResults.md): baselines are already 4.0-5.0/5, so loading the skill only adds token/tool overhead with no offsetting quality gain. Match the convention of the sibling analysis skill test-anti-patterns: reject bash/edit/create on every scenario. This skill is analysis-only ('do not modify any files'), so the constraint is a no-op for correct behavior but levels the playing field between baseline and skilled runs — scoring focuses on answer quality (weight 0.40+0.30) instead of tool-induced overhead. Applied to both eval.yaml and eval.vally.yaml. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * Address review: make well-maintained fixture self-contained and deterministic - Import System.Security.Authentication for AuthenticationException - Replace wall-clock assertion (token.ExpiresAt > DateTime.UtcNow) with a deterministic one anchored on a fixed clock (FixedNow), and drive the injected FakeClock from that fixed time. This removes the flakiness and makes the FakeClock injection meaningful — a better exemplar for the 'well-maintained' scenario.

Enable VS Code subagent fan-out for the dotnet-test code-testing agents (#847)
* Add VS Code subagent metadata to dotnet-test code-testing agents
Enable the code-testing-* Research-Plan-Implement pipeline to fan out as
subagents in VS Code while keeping the GitHub Copilot CLI working.
Frontmatter (VS Code "coordinator/worker" pattern; portable tool aliases that
map in both VS Code and the CLI):
- code-testing-generator: tools: [agent, read, search, edit, execute] + an
agents: list (researcher, planner, implementer, builder, tester, fixer,
linter); softened the three runSubagent({ agent, prompt }) blocks to
tool-agnostic delegation prose.
- code-testing-implementer: tools: [agent, read, search, edit, execute] +
agents: (builder, tester, fixer, linter).
- Leaf agents (researcher/planner/builder/tester/fixer/linter):
tools: [read, search, edit, execute].
Why explicit tools (not ["*"]): VS Code has no all-tools wildcard for ools:
and a subagent's ools: overrides its inherited set, so ["*"] matched nothing
and stripped subagents of file tools (they ran without read/edit/search). The
CLI treats ["*"] as all-tools, so this was VS-Code-specific. The portable
aliases agent/read/search/edit/execute map to real tools in both environments;
agents: is ignored by the CLI.
README: document the VS Code chat.subagents.allowInvocationsFromSubagents
setting (off by default) needed for the nested implementer->builder/tester/
fixer/linter layer to fan out on large scopes; the CLI has no such gate.
Validated end to end: VS Code shows researcher->planner->implementer fanning out
with real file I/O (no "subagents lack file tools" warning); CLI fan-out intact
with skills still loading and tests passing. An all-tools baseline used only
tools within this enumerated set, confirming no CLI capability is restricted.
* Include skill tool in code-testing agent tool allowlists
Address PR review: the explicit `tools:` allowlists omitted the `skill`
tool, but every code-testing-* agent's prompt instructs calling skills
(e.g. `code-testing-extensions` for per-language guidance, `test-gap-analysis`,
`assertion-quality`). Because `tools:` is an override, omitting `skill` can
prevent the agents from loading those skills in environments that gate skill
invocation by the allowlist.
Add `skill` to all eight agents:
- orchestrators (generator, implementer): [agent, skill, read, search, edit, execute]
- workers (researcher/planner/builder/tester/fixer/linter): [skill, read, search, edit, execute]
Re-verified in the Copilot CLI: full fan-out (researcher -> planner ->
implementer/tester), the `code-testing-extensions` skill is invoked, and the
generated tests pass.

Add TFM-aware buildTransitive->build forwarding guidance to msbuild skills (#836)
* Add TFM-aware buildTransitive->build forwarding guidance to msbuild skills buildTransitive/*.props should forward through the corresponding build/*.props (ownership chain buildTransitive -> build -> shared) rather than importing buildMultiTargeting/ directly. When build/ is packed per-TFM (build/<tfm>/), the forwarder must include the TFM segment and derive it from the file own folder, not $(TargetFramework) (NuGet nearest-match can serve a different asset folder), otherwise transitive consumers hit MSB4019. Updates extension-points (new Forwarding chain section), msbuild-antipatterns AP-13, and the msbuild-code-review agent. Lesson learned from microsoft/testfx#9431. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Clarify ambiguous props/targets glob in forwarder review check Address review feedback on dotnet/skills#836: spell out ".props/.targets forwarders" instead of the ambiguous `buildTransitive/*.props|targets`. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Tighten forwarding-chain guidance to reduce skill token overhead Condense the new extension-points Forwarding chain section (+26 -> +11 lines) and the AP-13 note by dropping the redundant non-TFM example and self-evident derivation explanation, keeping the chain rule, MSB4019 cause, and the TFM derivation expression. Lower token footprint addresses the skill-validator weighted-score token penalty without losing substance. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address review nits: AP range and forward-slash path Update the additional anti-patterns range to AP-16 through AP-22 (the reference doc now includes AP-22), and use a forward-slash build/MyPackage.props in the forwarding-chain prose to match the build/<tfm>/ convention used in the section.

Fix writing-mstest-tests activation by deflecting sibling skills (#835)
* Add MSTest deflection to assertion-quality and test-anti-patterns skills The writing-mstest-tests skill failed to activate in the plugin arm for six MSTest-specific scenarios (fix swapped Assert.AreEqual, modernize legacy patterns, type/string assertions, DynamicData with ValueTuples) because sibling skills captured the routing. assertion-quality and test-anti-patterns matched these prompts but lacked explicit deflection to writing-mstest-tests. Add DO NOT USE entries pointing MSTest test writing/fixing/modernizing to writing-mstest-tests. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address review: restore general assertion-fix deflection, align test-anti-patterns - assertion-quality: restore the general 'fixing or rewriting assertions' deflection (dropped in the prior edit) alongside the MSTest deflection, and fix punctuation to use comma-separated DO NOT USE items. - test-anti-patterns: align the 'writing new tests' deflection to also point MSTest test-writing to writing-mstest-tests, matching the body guidance.

skill-validator: restore 15K aggregate cap as the real Copilot CLI skill-menu budget (#803)
* skill-validator: restore 15K aggregate cap, document it as the real Copilot CLI skill-menu budget The per-plugin aggregate description cap had been raised 15,000 -> 20,000 -> 22,000 under the belief that 15K was 'a local repo policy, NOT a documented Copilot constraint'. That belief was wrong: the GitHub Copilot CLI renders the model-facing <available_skills> menu under a hard 15,000- char budget (the agent SDK's SKILL_CHAR_BUDGET, default 15e3, confirmed in CLI 1.0.36 and 1.0.61). Skills are listed alphabetically and emitted with their full <description> only until the budget is exhausted; every skill past the cut-off collapses to a bare name with no description and can no longer be reliably model-activated. Raising the validator cap merely masked this silent menu truncation — e.g. dotnet-test's run-tests and test-* skills stopped activating in plugin eval runs because they fell into the name-only overflow. Changes: - SkillProfiler.MaxAggregateDescriptionLength: 22,000 -> 15,000, with the comment rewritten to document the real Copilot CLI budget (and correct the prior 'not a documented constraint' claim). - CheckCommand aggregate now excludes skills marked 'disable-model-invocation: true' — the CLI drops those from the menu, so they do not consume the budget. This makes the cap satisfiable by hiding reference / agent-orchestrated primitives rather than only by trimming. - InvestigatingResults.md: document plugin-arm-only non-activation caused by skill-menu budget overflow, and how to fix it. Note: dotnet-test currently exceeds 15K and must be slimmed below it (via disable-model-invocation on reference/primitive skills plus description trims) before this cap can go green repo-wide. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * skill-validator: use source-generated regex for disable-model-invocation check Address review: replace Regex.IsMatch(pattern-string) with a [GeneratedRegex] partial method (AOT-friendly, no per-call cache lookup), matching FrontmatterParser's style. Runs once per skill during checks. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * skill-validator: parse disable-model-invocation via YAML to avoid block-scalar false positives The regex-based check matched any line in the frontmatter, so a block-scalar description that merely mentioned 'disable-model-invocation: true' on its own line was wrongly treated as disabling model invocation. Parse the frontmatter with the existing YAML deserializer (which correctly handles block scalars) by adding a DisableModelInvocation field to SkillFrontmatter, and drop the regex entirely.

Trim dotnet-msbuild skill-menu under 15K char limit (#809)
The rendered skill-menu for the dotnet-msbuild plugin was 16,679 characters, exceeding the 15,000 limit. Trim two categories of content from the 18 skill descriptions that do not help agents decide when to invoke a skill: - Remove INVOKES: clauses (which MCP tools / fallback shell commands a skill runs internally) — implementation mechanics, not routing signal. - Remove the boilerplate 'Only activate in MSBuild/.NET build context.' repeated verbatim in all 18 skills — redundant, since every description is already MSBuild-specific and each DO NOT USE FOR still excludes non-MSBuild build systems. USE FOR triggers and DO NOT USE FOR cross-references are preserved. Aggregate skill description size drops from 14,551 to 12,536 chars (rendered menu 16,679 -> 14,664).

run-tests: fix evals (query-filter regex, sibling skills, command observability) (#800)
* run-tests: fix evals (query-filter regex, sibling skills, command observability)
Investigated run-tests eval failures by running the validator locally.
- SKILL.md Step 3: document xUnit v3 --filter-query so the agent stops
answering that complex xUnit v3 filters 'cannot be combined'.
- eval.yaml: fix a broken assertion regex. The query-filter pattern is a
single-quoted YAML scalar using '\\s'/'\\[', which (unlike a double-quoted
scalar) is NOT unescaped, so the regex searched for a literal '\s' and
could never match. Corrected to single backslashes.
- eval.yaml: add additional_required_skills (filter-syntax / platform-detection)
to the filter and detection scenarios, so the isolated arm loads the sibling
reference skills that run-tests explicitly defers to.
- eval.yaml: ask the agent to show the exact command in execute-style prompts.
output_matches only sees the final assistant message; 'run my tests' prompts
make the agent execute and summarize ('tests passed'), so the recommended
command never appears. The assertions still catch wrong commands.

* run-tests: rewrite description for reliable plugin-arm activation
The run-tests skill activated reliably in the isolated eval arm but
unreliably in the plugin arm (all dotnet-test sibling descriptions
loaded), so every scenario's pluginImprovementScore went negative and
dragged min(isolated, plugin) below zero.
Lead the description with natural-language intent triggers that mirror
how the eval prompts phrase requests (run all tests, run a subset via
filters, produce TRX reports, collect crash/hang dumps, run a single
TFM) instead of opening with platform-detection mechanism, and add
explicit DO NOT USE redirects to code-testing-agent / mtp-hot-reload.
Stays under the 1024-char description cap.

* dotnet-test: fix run-tests plugin-arm activation via skill-menu budget
Root cause (verified against the Copilot CLI SDK skill renderer): the
model-facing skill menu has a 15000-char budget. Skills are listed
alphabetically and emitted with full descriptions only until the budget
is exhausted; the rest collapse to bare names with no description and
effectively cannot be model-activated. With 27 dotnet-test skills,
run-tests (alphabetical position ~20) fell into the name-only overflow,
so it never activated in the plugin eval arm even though it activated
reliably in isolation. This is a real user-facing discoverability bug,
not just an eval artifact.
Fix: hide reference/primitive skills that are never meant to be
model-invoked from the menu via 'disable-model-invocation: true', which
the SDK filters out of the budget entirely:
- filter-syntax, platform-detection, dotnet-test-frameworks,
code-testing-extensions, test-analysis-extensions — already
user-invocable:false reference data ('DO NOT USE directly').
- find-untested-sources, find-untested-sources-polyglot — researcher
primitives invoked by-name from the code-testing-researcher agent
(which has a manual fallback); no standalone evals.
These remain invocable by explicit name (agents/users), only auto-
suggestion is suppressed.
This frees enough budget that run-tests (plus migrate-xunit-to-xunit-v3
and mtp-hot-reload) now receive full descriptions; no previously-visible
skill regresses. Also trimmed the run-tests description so its menu block
fits with margin while keeping all activation triggers.

Fix test-gap-analysis skill activation in plugin eval runs (#801)
* Fix test-gap-analysis skill activation in plugin eval runs In plugin-mode eval runs (all dotnet-test skills loaded), test-gap-analysis lost activation: 'Acknowledge well-tested code' was stolen by assertion-quality and 'logic/null-check gaps' loaded no skill at all. Front-load the concrete 'would my tests catch a bug if the code changed' trigger phrasing the prompts use, and add a DO NOT USE -> test-gap-analysis redirect in assertion-quality for mutation-style reasoning. Both descriptions stay within the 1024-char cap; aggregate unchanged. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Restore Jest/TS activation signal for assertion-quality polyglot scenario The earlier trim of assertion-quality's description dropped the Jest/Vitest and toBeTruthy() signals, breaking plugin-mode activation for the 'Polyglot: Jest/TypeScript' scenario (agent answered directly, loading no skill). Restore those polyglot signals, and make the scenario prompt realistic — the prior prompt enumerated the full check catalog and Jest matcher list inline, acting as an answer key that let the agent self-serve without loading the skill. Verified locally: the scenario now activates assertion-quality in plugin mode across runs; all other assertion-quality scenarios still activate; description stays within the 1024-char cap.

Direct strategy must still run the Step 7 pre-completion gate (#793)
* Direct strategy must still run the Step 7 pre-completion gate The Direct strategy correctly skips the research/plan/implement sub-agents for small single-file tasks, but the wording let agents also skip the Step 7 pre-completion gate (test-gap-analysis + assertion-quality + scenario coverage) — treating a single-file task that enumerates specific behaviors as 'trivially small'. This is the dominant failure mode observed on behavior-enumerating tasks: the agent writes one test file directly and finishes with no assertion-strength or scenario-coverage check, producing weak assertions (mutation survivors) and missing required edge/negative cases. Clarify in both the generator Step 2 strategy table and the code-testing-agent SKILL.md that Direct trades away only the sub-agents, never the gate, and that a request naming a specific symbol or enumerating scenarios is not 'trivially small' and must run the gate. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address review: align Direct gate trigger with Step 7 threshold; clarify gate in SKILL.md - Step 2 Direct cell no longer introduces a separate 'names a specific symbol' gate trigger that contradicted Step 7.

Add prompt-scenario coverage check to code-testing-generator gate (#789)
* Add prompt-scenario coverage check to code-testing-generator gate The pre-completion gate already verifies assertion strength (pseudo-mutation and assertion-depth checks), but two recurring failure modes still slip through when the prompt enumerates specific behaviors: - Testing an *adjacent* function/helper instead of the exact feature named in the objective, leaving the requested behavior uncovered. - Covering only a single representative case when the scenario wording implies multiple variations or pins a condition to a specific position or structure. Add a third gate item that maps each enumerated scenario to a dedicated test, requires targeting the exact named function (preferring the canonical existing test file), and requires honoring range/positional qualifiers literally.

code-testing-generator: mandatory pre-completion self-review gate (#768)
* code-testing-generator: mandatory pre-completion self-review gate Replaces the prose `Verify tests are implementation-specific'' bullet in Step 7 of the code-testing-generator agent with a mandatory pre-completion self-review gate that invokes two existing plugin skills: 1. `test-gap-analysis'' (pseudo-mutation check) against the source files tested and the produced test files 2. `assertion-quality'' (trivial/tautological assertion check) against the produced test files Both skills already ship in plugins/dotnet-test; this PR only wires them into the generator's workflow as a mandatory gate before declaring a run complete. The two skills' `When to Use'' sections are extended to list `called by code-testing-generator as a pre-completion self-review step'' as a recognised use case so the model does not refuse the invocation. The skill descriptions are unchanged (frontmatter is already at the 1024-char limit). Rule 11 of the generator agent is updated to list the gate alongside final build, final test, and coverage-gap review as mandatory for ALL strategies including Direct. A matching rubric item is added to the ContosoUniversity scenario in the code-testing-agent eval (yaml and vally) so the LLM judge can verify the gate was actually invoked on the trajectory.

Harden Python testing guidance: reuse repo test runner/layout, handle heavy deps, never ship failing tests (#776)
* Harden Python testing guidance: reuse repo runner/layout, handle heavy deps, never ship failing tests Python is the weakest benchmark language (grade ~0.31): ~60% of generated tests fail and coverage stays ~2%.

Resolve Microsoft.AITools.BinlogMcp from nuget.org (#774)
The Microsoft.AITools.BinlogMcp package is now published on nuget.org as stable 1.0.0, so the binlog MCP server no longer needs the dnceng AzDO dotnet-tools feed or the --prerelease flag. Drop --prerelease and --add-source <azdo> from the binlog server args in both plugin.json and the .codex-plugin/.mcp.json mirror.

Add workspace-integrity guardrail to code-testing agents (#773)
The code-testing-generator/implementer agents could treat an unusual or
scaffolded workspace (e.g. a gutted repo with an injected synthetic module)
as corruption and "repair" it with git checkout/restore/reset/clean or rm,
restoring deleted tracked files and testing the wrong code.
- Replace generator Rule 5 ("Clean git first - stash changes") with an
explicit "Treat the workspace as delivered" rule, and add a "Never mutate
version control" rule. Output must be purely additive test files.
- Add a no-revert/no-clean invariant to the implementer's edit boundaries.
- Add a 'workspace integrity' eval to the code-testing-agent suite
(eval.yaml + eval.vally.yaml). The fixture looks gutted: a metricsd project
whose real core/io modules are committed at HEAD but deleted from the
working tree, leaving only a synthetic 'synthstr' decoy. A git restore would
resurrect the deleted sentinel files; graders fail if they reappear and
require passing pytest tests for the module as delivered.

code-testing-agent: pin down behavior in generated tests (#767)
Adds a new `Write Tests That Pin Down Behavior'' section to `unit-test-generation.prompt.md'' covering five universal test-craft principles: 1. Mutation thinking - each assertion would fail under a plausible bug 2. Property intersections - test combinations, not only coordinate axes 3. Behavior radius - assert on at least one secondary observable 4. Fixture realism - never set the parameter under test to a degenerate value 5. Quick self-review before declaring a test method done Mirrors the same depth requirements in `code-testing-implementer.agent.md'' Step 4 as a cross-language invariant block alongside the existing `Edit boundaries'' rules. Extends the existing `code-testing-agent'' eval rubrics (yaml and vally) with one or two depth-oriented bullets per scenario: * ContosoUniversity: minimal IsNotNull-only assertions + secondary observable check on controller actions * python-flask-tasks: minimal `is not None''-only assertions + at least one combined-property TaskService validation test * typescript-vitest-cart: minimal `toBeDefined''/`toBeTruthy''-only assertions + at least one intersection test (discount + tax + shipping together) Rationale and prior-art references in PR description.

Add anti-pattern for forking a project instance via <MSBuild> with path-neutral global properties (#770)
Adds msbuild-antipatterns AP-22 (in references/additional-antipatterns.md): using
the <MSBuild> task to build/publish a project with an extra global property that
does not change the output path forks a distinct instance sharing the same
OutputPath/IntermediateOutputPath as the instance the graph already builds,
causing duplicate builds and parallel-write races on PDBs, *.sourcelink, and
project.assets.json. Covers both shapes:
(a) a project re-invoking itself (publish-on-build), and
(b) project A invoking Build/Publish on another project B it consumes
(e.g. a test/layout project publishing a tool) — the more common trigger.
GOOD fixes: (a) static _IsPublishing + DependsOnTargets with a cycle guard;
(b) let the producer publish in its own build and have the consumer sequence it
with a non-output ProjectReference instead of re-publishing it. Also updates the
SKILL.md pointer (AP-16 through AP-22) and the quick-reference checklist.
Extends check-bin-obj-clash with the matching cause (self or cross-project
<MSBuild> Build/Publish with a path-neutral global property), binlog-based
detection via the evaluations/global-properties/double_writes tools, the two
fixes, and an _IsPublishing row in the global-properties table.
Adds eval coverage: a publish-on-build smell in the msbuild-antipatterns review
fixture (LibA.csproj) plus a matching rubric line in eval.yaml and eval.vally.yaml.

Add find-untested-sources-polyglot skill (tree-sitter, 9 languages) (#735)
* Add find-untested-sources-polyglot skill (tree-sitter, 9 languages) Sibling of the C# find-untested-sources skill that uses tree-sitter (via tree-sitter-language-pack) to extract declarations + imports across Python, TS/JS, Go, Java, Rust, C#, and Ruby with no build step. Output schema mirrors the C# skill's so prompts can consume either tool. Pairing strategies per language: - Import resolution (Python module path, TS/JS relative ./../index.*, Go pkg/<name>.go, Java FQCN, Rust use::, Ruby require). - Identifier overlap (every >=4-char token in the test source is cross-referenced with the declared-name index). Smoke-tested on: - python-flask-tasks fixture: 8 source / 0 test, 8 untested. - typescript-vitest-cart fixture: 8 source / 0 test, 8 untested (node_modules pruned). - AITestAgent C# repo: 3138 source / 761 test, 1419 tested, 1719 untested, 15 orphan. - gh-skills Go repo: 14 source / 7 test, 8 tested, 6 untested, 0 orphan. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Polyglot: union structure+symbols for declarations (fixes Go types, Python methods) tree-sitter-language-pack's ProcessResult exposes two complementary views: - structure: top-level items (classes, functions, structs, traits) - symbols: flat declared-name list Neither alone is complete: - Go: structure has methods/functions but NOT 'type' declarations; symbols has the types. Without union, a test that references a struct name finds no matching source and the source is incorrectly marked untested. - Python: structure stops at top-level, symbols also lists nested methods. - Rust: structure has structs and impls; symbols has fn names inside impls. Fix: union both lists, then drop kind='module'/'namespace' (these are packaging items that would cause false positives, e.g. Java's tree-sitter output emits the package name 'com' as a Module). Verified across all 9 supported languages with synthetic source+test+orphan fixtures (python, javascript, typescript, tsx, go, java, rust, csharp, ruby): each fixture now reports tested=1, untested=1, orphan=0. Real-repo regression check (AITestAgent C#): tested 1419 -> 1429, untested 1719 -> 1709 (10 sources now correctly paired via types previously missing from the declared-name index). Orphan count unchanged at 15 (no false-positive pairings introduced). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address review feedback on find-untested-sources-polyglot Code fixes (find_untested_sources.py): - Java test-file detection: drop the `name.startswith("test")` clause so data files like `testdata.java` are no longer misclassified as tests. Keep the documented `*Test.java` / `*Tests.java` rule and the path segment heuristic. - C# test-file detection: tokenize the (PascalCase-preserving) stem and treat the file as a test only when the final word is `Test` or `Tests`. This correctly classifies `UserServiceTests.cs` while no longer misclassifying `Contest.cs`, `Latest.cs`, `Manifest.cs`. - Identifier-overlap pairing: iterate the test's referenced identifiers and do O(1) lookups in `by_decl` instead of scanning every declaration in the index. Pairing is now O(#test_identifiers) per test instead of O(#decls × #tests) across the run, which matters on large repos. - JS/TS relative-import normalization: collapse `<seg>/../` segments in a fixed-point loop instead of a single regex pass so chained imports like `../../foo` and `a/b/../../c` resolve fully. Doc fix (SKILL.md): - Clarify that `symbols` is unioned with `structure` rather than being used only as a fallback when `structure` is empty, matching the actual parse_file implementation. - Tighten description to stay within the per-skill (1,024 chars) and plugin aggregate (20,000 chars) limits enforced by skill-validator. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Allow tree-sitter.github.io in known-domains for find-untested-sources-polyglot The polyglot skill's SKILL.md links to https://tree-sitter.github.io/ for the tree-sitter project; add the domain to eng/known-domains.txt so the skill-validator reference scanner stops failing with EXTERNAL-DOMAIN. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR #735 review feedback (round 2) - parse_file: log a stderr WARN when tree-sitter parsing throws instead of silently returning a 0-declaration FileInfo, so users can see when results are degraded by parser failures. - Python relative imports: _python_module_to_path now respects PEP 328 leading dots, resolving 'from .utils import x' against the test file's package rather than treating it as an absolute 'utils.py' at repo root. Returns an empty candidate set when no test context is available or when the imported name isn't captured ('from . import x'), to avoid false-positive pairings. - Go import resolution: _build_indexes now produces a by_filename index, and _resolve_test_imports looks up '<pkg>.go' in O(1) per import instead of scanning every source path for each import target. - tested_sources: emit sorted by path for deterministic JSON output across runs (matches the existing sort on untested_sources / orphan_tests). - SKILL.md: JS/TS test-detection row now lists the 'test' path segment to match the implementation.

Add find-untested-sources skill (C# parse-only test pairing) (#733)
* find-untested-sources: C# static test-pairing prototype Parse-only Roslyn analysis that maps C# source files to the test files referencing their declared types and lists production sources with no referring test. No Compilation, no MetadataReferences, no binding. - File discovery prunes bin/obj/node_modules/.git and generated *.g.cs. - Test classification by .csproj suffix or test-SDK reference. - Source index records (ShortName, Namespace, FilePath) per parsed file. - Test scan walks IdentifierTokens, disambiguates strictly against the test file's using directives + enclosing namespace. - Suggests a test-file path by mirroring the source under the test project that already <ProjectReference>s the source's project. Runs in ~9s on a ~3,900 .cs-file repo (AITestAgent + msbench fixtures). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address review feedback on find-untested-sources Code fixes (Find-UntestedSources.cs): - ProjectFor: sort .csproj matches and wrap enumeration in try/catch so selection is deterministic when a directory contains multiple project files. - GetNamespaceFor: walk all enclosing namespace declarations and join from outermost to innermost so nested namespace blocks (namespace A { namespace B { ... } }) return "A.B" rather than just "B". - Test scan: stop unconditionally skipping global-namespace declarations. Global types are visible without a using directive, so accept them as visible to any test file. Previously, types without a namespace were never attributed to any test and always reported as untested. - BuildProductionToTestProjectMap: sort the recursive .csproj enumeration and wrap in try/catch so the "first write wins" rule selects the same test project across runs/machines regardless of filesystem ordering. - IsSkippedFile: switch suffix comparisons to OrdinalIgnoreCase and collapse the five if statements into a single loop over an array. Skill metadata (SKILL.md): - Tighten the description so the skill stays under the 1,024-character per-skill limit and the dotnet-test plugin stays under the 20,000-char aggregate limit enforced by skill-validator.

code-testing-agent: mention find-untested-sources for C# discovery (#734)
* code-testing-agent: mention find-untested-sources for C# discovery Adds a conditional pointer (gated on 'when available') to the find-untested-sources skill in two places: - SKILL.md Step 3 (Research Phase): high-level note for C# / .NET multi-file scopes — prefer the helper over manual find/grep/glob walks. - code-testing-researcher.agent.md Section 7 (Discover Preexisting Tests): directive instruction telling the researcher to invoke the helper before manually pairing source <-> test files, and to use its source_to_tests / untested output to fill the research document. Both callouts are phrased as 'when available', so installations without the find-untested-sources skill continue to work via manual discovery. Adds no behavior for non-C# repos. Context: in a 5x136-instance internal experiment on the msbench .NET test bench, adding equivalent pointers to the routed code-testing-agent yielded a 15.67% input-token reduction at neutral pass rate — the model trusted the documented pairing heuristics and skipped its own discovery walk. The helper itself was not invoked in those runs (the Copilot CLI router did not auto-load the sibling skill), so the measured win comes from the doc text causing the model to short-circuit its manual exploration, not from the helper executing. Depends on dotnet/skills#733 (which adds the find-untested-sources skill itself). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * code-testing-agent eval: grade find-untested-sources usage on C# scenario PR #734 adds a doc pointer steering the researcher toward the `find-untested-sources` skill on .NET / C# multi-file tasks. The existing ContosoUniversity scenario is the natural fit: it's the only C# multi-file scenario in this eval, and the new pointer is .NET- scoped. Add one rubric item to that scenario (in both eval.vally.yaml and the legacy eval.yaml) asking the grader to verify the researcher actually leveraged the helper — either by citing its `source_to_tests` / `untested` JSON output in `.testagent/research.md`, or by executing `scripts/Find-UntestedSources.cs` — instead of falling back to manual `find` / `grep` / `glob` walks. Gated on `when available in the workspace` to match the SKILL.md wording, so installs without find-untested-sources are not penalized.

migrate-xunit-to-mstest: forbid CancellationToken.None replacement explicitly (#758)
* migrate-xunit-to-mstest: forbid CancellationToken.None replacement explicitly The TestContext.Current.CancellationToken guidance already forbids replacing it with a fresh CancellationTokenSource, but real-world agent migrations have been observed substituting CancellationToken.None instead, which silently drops the test host's cancellation linkage.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR review: source reserved list from dotnet new --help, note workload/package availability, tighten version-refresh - Clarify the reserved shortName set is the current dotnet new subcommands (authoritative source: dotnet new --help); create is verified as a real subcommand (alias behind dotnet new <template>). - template-discovery: note that some mapped short names (maui, winui3, aspire, func, orleans) need workloads/template packages, with fallback to dotnet new list/search. - template-instantiation: keep template versions by default; if refreshing, use dotnet list package --outdated + user confirmation and constrain to same major/minor rather than always latest stable. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address 2nd review round: enforce eval negatives, split combined assertion, reframe reserved list - smart-defaults evals: enforce --no-https absence (auth scenario), absence of minimal-API flag (controllers scenario), and no newer --framework TFM when net8.0 is explicitly required, using output_not_contains/output_not_matches. - comparison eval: split the combined (auth|aot|docker|controllers) check into four separate output_matches assertions so partial comparisons fail. - template-validation/authoring: reframe the reserved shortName list as non-exhaustive examples and source the authoritative set from dotnet new --help; drop the specific create-alias assertion in favor of parsing-ambiguity wording. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Make template-comparison evals robust to CI SDK currency Switch the Blazor comparison scenario from blazorserver (absent in the CI SDK) to blazor (Blazor Web App) vs blazorwasm, both reliably present in .NET 8+, and instruct the agent to inspect each via --help. Update the SKILL.md example reference for currency. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add CLI-failure resilience guidance to discovery/comparison skills The isolated eval runs failed because the agent ran 'dotnet new <t> --help', hit the template engine's global-mutex/persistence error (common when the command runs concurrently in a sandbox), and then returned no answer at all. Instruct both skills to run 'dotnet new' calls sequentially, retry once on a transient mutex/persistence error, and fall back to the intent/parameter mapping so a concrete answer is always produced instead of empty output. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR review: accurate flags + robust negative-assertion prompts - template-smart-defaults SKILL.md: drop the non-existent --publish-aot flag. Clarify --aot is a dotnet new flag only on templates that expose it (console/worker/grpc, not webapi) and that publish-time AOT is the MSBuild PublishAot=true property, not a dotnet new flag. - template-discovery SKILL.md: replace the hardcoded --enable-docker mapping (not a real flag on common templates) with generic 'confirm with --help'. - smart-defaults evals: tighten the negative-assertion prompts to output only the command line and not mention unused flags, so a negated explanation can't trip output_not_contains/output_not_matches. Switch the AOT scenario from webapi to worker (which actually supports --aot). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR review round 3: scope negative checks, de-emphasize stale lists - smart-defaults evals: anchor the negative assertions to the 'dotnet new' command line (same-line regex) instead of whole-output substring/regex, so a flag mentioned only in prose can't fail the test. - template-validation / template-authoring: mark the dotnet new subcommand examples as illustrative/version-dependent and tell readers not to hardcode them; the live 'dotnet new --help' output is canonical. - template-comparison: fix the example table's AOT row — webapi/webapp do not expose a --aot template flag; native AOT is publish-time via PublishAot.

code-testing-implementer: add mandatory harness-discovery check (#757)
* code-testing-implementer: add mandatory harness-discovery check
Generic CI/benchmark verifiers run the framework's default discovery from the repo root. Tests that pass via a scoped command (e.g. 'dotnet test MyProject.Tests.csproj', 'bundle exec rspec subgem/spec', 'Invoke-Pester -Path ./tools') but are invisible to the harness count as 0 generated tests.
Repeatedly observed in msbench cta-nightly runs:
- new C# test project never 'dotnet sln add'ed (ocelot)
- Pester tests placed under custom directories invisible to default Invoke-Pester (homebrew, ruby/ruby)
- RSpec specs placed in a sub-gem's spec/ dir invisible from repo root (fastlane)
Changes:
- code-testing-implementer: capture baseline test count in Step 2, new Step 7 'Verify Harness Discovery (MANDATORY)' with concrete failure examples, HARNESS_DISCOVERY line in report template, reminder after Step 3 to revisit registration if Step 4 creates a new project.
- code-testing-researcher: instruct to record BOTH scoped test command and harness-equivalent discovery command in .testagent/research.md.
- dotnet.md: strengthen 'Registering a new test project' heading to MANDATORY when dotnet new was used; add 'Harness Discovery Check' section with 'dotnet test <solution> --list-tests' from repo root.
- powershell.md: add 'Harness Discovery Check' section with default-config Invoke-Pester from repo root.
- ruby.md: add gem-monorepo trap guidance (fastlane, ruby/ruby) in Test Placement Contract; add 'Harness Discovery Check' section with 'bundle exec rspec --dry-run' from repo root.
* Address review feedback on harness-discovery check
- dotnet.md: replace stale `Step 8 cleanup` reference with the actual Step 3 (`Register Test Project with Build System`).
- dotnet.md: demote `Harness Discovery Check` to `###` so it nests under the parent `## .csproj / .sln Handling` section alongside `### Registering...`.
- dotnet.md: replace `\s\{4\}` (non-POSIX) in the grep regex with 4 literal spaces so the count works under BRE.
- ruby.md: group the rake/rails fallback with `{ ...; } | wc -l` so the pipe applies to both branches of `||`.

migrate-xunit-to-mstest: add learnings from dotnet/sdk migration (#756)
* migrate-xunit-to-mstest: add learnings from dotnet/sdk migration Refines the skill based on a real migration of 5 test projects in dotnet/sdk: - MSTest.Sdk implicit global using: do not add `<Using Include='Microsoft.VisualStudio.TestTools.UnitTesting' />` or per-file `using` in MSTest.Sdk projects (it's already in scope). Note Option A (`MSTest` metapackage) still needs the per-file using. - `Assert.IsExactInstanceOfType<T>` (MSTest 4.1+) is the proper single-call equivalent of xUnit's exact-type `Assert.IsType<T>`; previous guidance silently degraded it to assignable semantics (closes #755). - `Assert.AreSequenceEqual` (MSTest 4.3+) is the modern element-wise equivalent of xUnit's `Assert.Equal` on `IEnumerable<T>`, avoiding the `CollectionAssert` + `.ToList()` dance and the MSTEST0065 trap on plain `AreEqual`. - Clarify `AwesomeAssertions` ships in the `FluentAssertions` namespace, so it's a no-source-change swap. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * SKILL.md: split IsType/IsAssignableFrom row to avoid implying drop-in equivalence Address dotnet/sdk#54727 review comment: the Step 6 summary table conflated xUnit's exact-type Assert.IsType<T> and assignable Assert.IsAssignableFrom<T> into a single row, which implies both map interchangeably even though their semantics differ. Split into three rows -- IsType<T> -> IsExactInstanceOfType<T>, IsNotType<T> -> IsNotExactInstanceOfType<T>, IsAssignableFrom<T> -> IsInstanceOfType<T> -- and explicitly call out the silent-weakening trap. The cheatsheet already maps these correctly; this aligns the SKILL.md summary with the cheatsheet so the at-a-glance table doesn't suggest a wrong mapping. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * SKILL.md: resolve Step 3/Step 4 conflict on the MSTest using for Option B Address review feedback on dotnet/skills#756: Step 3 said to skip the per-file 'using Microsoft.VisualStudio.TestTools.UnitTesting;' on Option B (MSTest.Sdk provides it as an implicit global using), but Step 4 unconditionally instructed replacing xUnit usings with that MSTest using -- so an agent following Step 4 literally would re-add the redundant using on Option B projects. Also drop the dangling 'Step 4 rewriter' phrasing in Step 3 (there is no rewriter in Step 4, just a list of mechanical rewrites the agent applies). Step 4 now explicitly says to skip the MSTest using on Option B and only remove the 'using Xunit;' lines, matching Step 2's note and Step 3's branch instructions.
