Skill: Run Automated Tests

Purpose

Work out how the target repository expects automated tests to be run (commands, frameworks, prerequisites, and scope), then run the best-matching test suite under a safety-first interaction policy.

---

Core Objective

Primary goal: produce test execution results through evidence-based command selection and safety guardrails.

Success criteria (all must hold):

1. ✅ Test plan discovered: the evidence source is identified (documentation, CI configuration, or build manifest)
2. ✅ Command selected: the appropriate test command is chosen for the mode (fast/ci/full) and the constraints
3. ✅ User confirmation obtained: approval received before installing dependencies, using the network, or starting services
4. ✅ Tests executed: the command was run with its output and exit code captured
5. ✅ Results summarized: a test plan summary with evidence, commands, execution status, and failures (if any)

Acceptance test: can a developer reproduce the test execution by following the test plan summary, with no extra context?

---

Scope Boundaries

This skill owns:

• Discovering the test command from repository evidence (documentation, CI, build manifests)
• Selecting the appropriate test command for the mode and the constraints
• Executing tests behind safety guardrails and user confirmation
• Summarizing test results with evidence and failure diagnostics

This skill does not own:

• Test quality assessment or coverage analysis (use review-testing)
• Fixing failing tests or debugging test failures (use orchestrate-repair-loop)
• Writing new tests or test infrastructure (use the development skills)
• Reviewing test code against best practices (use review-testing)

Handoff point: once the tests finish (pass or fail), hand off to orchestrate-repair-loop to fix the failures, or to review-testing for a quality assessment.

Use Cases

• You cloned a repository and want the right test command without guessing.
• The repository has several test layers (unit/integration/e2e) and you need a safe default run plan.
• CI failed and you want to reproduce it locally by running the same commands the workflow uses.

Behavior

1. Establish scope and constraints (ask when unclear)

   • With nothing specified by the user, default to a fast, local, non-destructive run:
     • Unit tests only, no external services, no Docker, no network-dependent setup.
   • Where it matters, have the user pick a mode:
     • fast: unit tests only, minimal setup.
     • ci: mirror the CI workflow commands as closely as possible.
     • full: include integration/e2e tests and service dependencies.
   • Ask whether Docker is allowed, whether network access is allowed, and whether dependency installation is allowed.

2. Discover the test plan (evidence-based)

   • If CLAUDE.md or .ai-cortex/config.yaml exists, prefer the test_command recorded there; otherwise discover it from the sources below. See docs/guides/project-config.md.
   • Read these sources in order; stop early once a clear, unambiguous test command turns up:
     • README.md, CONTRIBUTING.md, TESTING.md, docs/testing*, Makefile
     • CI configuration: .github/workflows/*.yml, .gitlab-ci.yml, azure-pipelines.yml, Jenkinsfile
     • Build manifests: package.json, pyproject.toml, setup.cfg, tox.ini, go.mod, pom.xml, build.gradle*, *.csproj, Cargo.toml
   • Identify:
     • The primary test entry point (npm test, pnpm test, yarn test, pytest, tox, go test, dotnet test, mvn test, gradle test, cargo test, and so on)
     • Test layers and markers (unit, integration, e2e)
     • Environment prerequisites (DB, Redis, Docker Compose, required environment variables, secrets)
     • How CI sets up its dependencies (services, caches, artifacts)
   • Prefer an explicit statement in the documentation or CI over heuristic inference.

3. Choose the execution plan

   • In ci mode: derive the run sequence from the repository's CI workflow steps (closest match).
   • In fast mode: pick the most direct unit test command, the one with the fewest prerequisites.
   • With several stacks present (backend + frontend, say), suggest running each stack separately in a fixed order.
   • If the plan needs a dependency install or a service start, ask for confirmation before continuing.

4. Execute with guardrails

   • Always print the exact command you are about to run, before running it.
   • Use a working directory rooted at the target repository (default .).
   • Capture and summarize failures:
     • The first failing command and its exit code
     • The most relevant error excerpt
     • Next actions (missing toolchain, missing environment variable, service not running, and so on)
   • Avoid destructive operations:
     • Do not run rm -rf, git clean -fdx, docker system prune, or database drop/migration commands without the user's explicit approval.
   • If the repository needs secrets, do not ask the user to paste them into the chat. Use a .env file, a secret manager, or the documented local development flow.

Input & Output

Input

• Target repository path (default .).
• Mode: fast (default), ci, or full.
• Constraints: dependency install allowed (yes/no), network allowed (yes/no), Docker allowed (yes/no).

Output

• A short "test plan summary" containing:
  • Evidence: which files/paths informed the plan
  • The selected commands (in order)
  • Assumptions and prerequisites
  • What was executed and what was skipped (and why)
• Enough of the command log to debug a failure (do not dump extremely long logs unless asked).

Restrictions

Hard Boundaries

• Do not invent a test command when evidence exists (documentation/CI takes precedence).
• Do not install dependencies, run Docker, or start external services without confirmation.
• Do not modify repository files unless the user explicitly asks (exception: generating a report file when the user asks for an artifact).
• Do not leak secrets; do not request sensitive credentials in the chat.

Skill Boundaries (avoid overlap)

Do not do these (other skills handle them):

• Test quality assessment: judging test coverage, test design, or testing best practices → use review-testing
• Fixing test failures: debugging failing tests, repairing broken test code, or root-causing → use orchestrate-repair-loop
• Writing tests: creating new test cases, test infrastructure, or a test framework → use the development/implementation skills
• Code review: reviewing test code for quality, maintainability, or best practices → use review-testing
• Repository analysis: full codebase structure analysis or architecture review → use review-codebase

When to stop and hand off:

• Tests fail and the user asks "why?" or "how do I fix it?" → hand off to orchestrate-repair-loop for debugging and repair
• The user asks "are these tests any good?" or "what is our coverage?" → hand off to review-testing for a quality assessment
• The user asks "can you write tests for X?" → hand off to the development workflow for test implementation
• Tests pass and the user asks "what should we test next?" → hand the test strategy suggestion to review-testing

Self-Check

Core success criteria (all must hold)

• Test plan discovered: the evidence source is identified (documentation, CI configuration, or build manifest)
• Command selected: the appropriate test command is chosen for the mode (fast/ci/full) and the constraints
• User confirmation obtained: approval received before installing dependencies, using the network, or starting services
• Tests executed: the command was run with its output and exit code captured
• Results summarized: a test plan summary with evidence, commands, execution status, and failures (if any)

Process quality checks

• Evidence-based selection: did I identify at least one authoritative source for the test command (a doc file, a CI workflow, or a build manifest)?
• Safety guardrails applied: did I ask for confirmation before installing dependencies, using the network, starting Docker/services, or any state-changing action?
• Commands printed: did I print the exact command before running it?
• Failures diagnosed: when tests failed, did I give the first failing command, the exit code, and a likely root-cause category?
• No destructive operations: did I avoid running destructive commands (rm -rf, git clean, docker system prune, database drops) without explicit approval?
• No secret leakage: did I avoid asking for sensitive credentials in the conversation, using a .env file or the documented local development flow instead?

Acceptance test

Can a developer reproduce the test execution by following the test plan summary, with no extra context?

If no: the test plan summary is incomplete. Add the missing evidence, commands, or prerequisites.

If yes: the skill run is complete. Continue to the handoff if one is needed.

Examples

Example 1: a JavaScript repo with package.json

User: "run the tests for this repository."

Agent:

1. Check the package.json scripts and .github/workflows/*.
2. Settle on fast mode and propose:
   • npm test (or pnpm test / yarn test if the repository standardizes on one)
3. Ask: "install dependencies (npm ci) and allow network access?"
4. Run:
   • npm ci
   • npm test
5. Summarize the results and point at the failing test output, if any.

Example 2 (edge case): a monorepo that needs Docker for integration tests

User: "mirror CI locally."

Agent:

1. Parse .github/workflows/ci.yml and identify the separate jobs:
   • Backend unit tests
   • Frontend tests
   • Integration tests with docker compose
2. Ask for confirmation:
   • Docker allowed
   • Network allowed
   • Which jobs to run (all of them, or only the failing one)
3. Execute in a controlled order:
   • Install deps per job
   • Run unit tests first
   • Start the services for the integration tests
4. If the integration tests fail, summarize:
   • Service health/port conflicts
   • Missing environment variables
   • How the CI configuration differs from the local one
