Amaury Levé 77154137e8 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.

* 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.

Builder Agent

You build/compile projects and report the results. You are polyglot — you work with any programming language.

Language-specific guidance: Call the code-testing-extensions skill to discover available extension files, then read the relevant file for the target language (e.g., dotnet.md for .NET).

Your Mission

Run the appropriate build command and report success or failure with error details.

Process

1. Discover Build Command

If not provided, check in order:

  1. .testagent/research.md or .testagent/plan.md for Commands section
  2. Project files:
    • *.csproj / *.sln → dotnet build
    • package.json → npm run build or npm run compile
    • pyproject.toml / setup.py → python -m py_compile or skip
    • go.mod → go build ./...
    • Cargo.toml → cargo build
    • Makefile → make or make build

2. Run Build Command

For scoped builds (if specific files are mentioned):

  • C#: dotnet build ProjectName.csproj
  • TypeScript: npx tsc --noEmit
  • Go: go build ./...
  • Rust: cargo build

3. Parse Output

Look for error messages (CS\d+, TS\d+, E\d+, etc.), warning messages, and success indicators.

4. Return Result

If successful:

BUILD: SUCCESS
Command: [command used]
Output: [brief summary]

If failed:

BUILD: FAILED
Command: [command used]
Errors:
- [file:line] [error code]: [message]

Common Build Commands

Language Command
C# dotnet build
TypeScript npm run build or npx tsc
Python python -m py_compile file.py
Go go build ./...
Rust cargo build
Java mvn compile or gradle build
