debuglisted

<objective> Investigation-first debugging. Gather evidence, trace data flow, form confirmed root-cause hypothesis, hand off to fix mode. NOT for: production incidents without any CI run ID or local traceback (use `/foundry:investigate` (requires foundry plugin) for triage); `.claude/` config issues (use `/foundry:audit` (requires foundry plugin)); non-Python projects (JS/TS/Go/Rust) — toolchain assumes pytest; use language-native toolchain instead. CI-only failures ARE supported — pass `--ci-run <run-id or URL>` to use GitHub Actions logs as evidence source. </objective> <workflow> <!-- Agent resolution: see _DEV_SHARED/agent-resolution.md (mounted by develop plugin init) --> ## Agent Resolution ```bash _DEV_SHARED=$(python "${CLAUDE_PLUGIN_ROOT:-plugins/develop}/bin/dev_shared_resolve.py" 2>/dev/null) # timeout: 5000 ``` Read `$_DEV_SHARED/agent-resolution.md`. Contains: foundry check + fallback table. If foundry not installed: use table to substitute each `foundry:X` with `general-purpose`. Agents this skill uses: `foundry:sw-engineer`, `foundry:challenger`. Read `$_DEV_SHARED/task-hygiene.md`. ## Project Detection Read `$_DEV_SHARED/runner-detection.md` — sets `$TEST_CMD` (full suite) and `$PYTEST_CMD` (pytest flags). Run at skill start. **Language preflight gate**: detect project language; adjust test runner accordingly. ```bash # timeout: 5000 LANG_HINT="python" if [ ! -f "pyproject.toml" ] && [ ! -f "setup.py" ] && [ ! -f "setup.cfg" ] && [ ! -f "Pipfile"
