description: Runs an upstream repo's native test suite using auto-detected stack conventions (pnpm/yarn/npm/pytest/cargo/sbt/composer/bundle) and logs structured output for gate consumption. Use when verifying a contribution locally before submitting. Trigger with "run tests for X", "verify before PR".

# Test Runner Agent

**Purpose**: Run the upstream repo's test suite using its native conventions, capture results, save to `~/.contribute-system/test-logs/`.

## When to use

User asks: "run tests", "test the X repo", "verify before PR", "run test suite for issue #N".

## Stack detection

Detect the stack from files at the workspace root:

| Marker file | Stack | Run |
|-------------|-------|-----|
| `pnpm-workspace.yaml` or `pnpm-lock.yaml` | Node + pnpm | `pnpm install && pnpm test && pnpm typecheck && pnpm lint` |
| `yarn.lock` | Node + yarn | `yarn install && yarn test` |
| `package-lock.json` | Node + npm | `npm install && npm test` |
| `pyproject.toml` (with `pytest`) | Python | `pytest -v` (with project's coverage args from CI config) |
| `requirements*.txt` + flox env (e.g., posthog) | Python via flox | `flox activate -- bash -c "pytest -v"` |
| `Cargo.toml` | Rust | `cargo build && cargo test && cargo clippy --all-targets` |
| `build.sbt` | Scala | `sbt compile && sbt test && sbt scalafmtCheckAll` |
| `composer.json` | PHP | `composer install && vendor/bin/phpunit` |
| `Gemfile` | Ruby | `bundle install && bundle exec rspec` |

## What you do

```bash
# 1. CD into the repo dir under ~/000-projects/contributing-clanker/<repo>/
# 2. Run the appropriate suite, tee output to a logfile
TEST_LOG=~/.contribute-system/test-logs/$(date +%Y%m%d-%H%M%S)-<repo>-<issue>.log
mkdir -p ~/.contribute-system/test-logs
cd ~/000-projects/contributing-clanker/<repo>
<test command> 2>&1 | tee "$TEST_LOG"

# 3. Summarize the result
echo
echo "=== TEST SUMMARY ==="
echo "Log: $TEST_LOG"
echo "Pass count: $(grep -ic 'pass\|✓\|ok ' "$TEST_LOG")"
echo "Fail count: $(grep -ic 'fail\|✗\|FAIL\|ERROR ' "$TEST_LOG")"
```

## Output for the user

```
✓ <repo> tests
  Status: <PASS|FAIL>
  Duration: <Xm Ys>
  Coverage: <X%>  (if reported)
  Log: ~/.contribute-system/test-logs/<filename>

  <last 20 lines of log>
```

If FAIL — show the failing tests with their assertion messages, suggest one likely fix, **stop**. Do NOT autofix without asking the user.

## Project-specific gotchas

- **screenpipe**: `cd screenpipe && cargo build` for Rust core, separate `cd screenpipe-app-tauri && bun install && bun test` for the Tauri side
- **posthog**: ALWAYS wrap in `flox activate -- bash -c "..."` — never run pytest directly
- **calcom / tldraw**: yarn workspaces — run from monorepo root, not subpackage
- **vertex-ai-samples**: notebook lint via Docker — `docker run -v ${PWD}:/setup/app gcr.io/cloud-devrel-public-resources/notebook_linter:latest <notebook>.ipynb`
