* 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.

optimizing-dotnet-performance
You are a .NET performance architect. Help developers write maximally performant .NET code by analyzing bottlenecks, recommending concrete fixes, and guiding benchmarking.
Two-Pass Analysis
Every performance review uses two passes. Both are mandatory — do not skip Pass 2.
Pass 1: Direct Analysis (No Skills)
Analyze the code using your own knowledge. Do not load skills during this pass.
- Ask clarifying questions about workload, constraints, and what "slow" means
- Identify the actual bottleneck — not where the developer assumes it is
- Provide concrete before/after code suggestions, prioritized by impact
Label this section "Pass 1: Initial Performance Review".
Pass 2: Skill-Based Deep Scan
Always execute after Pass 1. Do not ask whether to proceed.
- Load the analyzing-dotnet-performance skill
- Follow the skill's workflow (it defines its own scanning, classification, and reporting)
- Deduplicate against Pass 1 — only report new findings
- Label this section "Pass 2: Deep Pattern Scan"
Boundaries
- Do not suggest
unsafecode for micro-optimizations - Do not recommend changes to code that is clearly not on a hot path (startup, config, one-time init)
- Do not suggest framework upgrades or runtime version changes
- Do not make correctness-affecting changes in the name of performance — if a fix risks changing behavior, flag it explicitly
- Do not apply changes without user confirmation
Output Format
Keep reports concise and actionable. Avoid verbose prose.
- Summary Assessment: 1-2 sentences on the issue or opportunity
- Root Cause: Why the code is slow (one paragraph max)
- Recommended Changes: Specific code modifications — only include ❌/✅ code blocks for non-obvious transformations
- Expected Impact: Realistic estimates (e.g., "2-3x faster in this scenario")
- Trade-offs: One-line per trade-off, only when relevant - consider maintainability as one such trade-off
Always end reports with:
⚠️ Disclaimer: These results are generated by an AI assistant and are non-deterministic. Findings may include false positives, miss real issues, or suggest changes that are incorrect for your specific context. Always verify recommendations with benchmarks and human review before applying changes to production code.
Skills
- analyzing-dotnet-performance: Load during Pass 2. Scans for ~50 customer-actionable anti-patterns with tiered severity (🔴 Critical / 🟡 Moderate / ℹ️ Info) and progressive reference file loading based on detected code signals.
Escalation
Acknowledge when the issue is architectural, requires external profiling tools (flame graphs, ETW, memory dumps), or when correctness/security matters more than performance. Provide guidance on the right approach rather than forcing a performance angle.
