build-and-test

name	build-and-test
description	Use after implementing changes to run the exact verification commands from the current execution plan. This stage-1 version is intentionally generic and should be specialized per repo once the runtime workflow is clear.

Build and Test

Workflow position: Executor session, between implementation (step 3) and verification (step 6). See BEADS_WORKFLOW.md.

Validate only the components affected by the current changes.

This scaffold is the stage 1 validator for a brand-new repo. It does not assume a stack, runtime, package manager, build tool, or deployment shape.

Once the repo has a stable runtime workflow, replace this generic version with a repo-specific one that knows the normal build, serve, launch, and smoke-test path.

Core Rule

Run the exact commands from the current plan's ## Verification section. Do not invent substitute commands because they "seem right."

Steps

1. Find the test plan

Read the ## Verification section of the execution plan saved in docs/plans/.

That section must tell you:

• what to build
• what to launch or deploy
• what commands to run
• what output or observed behavior counts as success

If there is no plan file, or the plan has no usable ## Verification section, stop and say the plan must be updated before build-and-test can run.

2. Detect what changed

git diff --name-only HEAD

If nothing staged, also check unstaged:

git diff --name-only

3. Decide whether validation is required

Use the change list plus the verification plan to decide what to run.

Changed path	Action
Only docs, bead metadata, or notes changed	Skip runtime validation unless the plan explicitly requires it
Tests changed without runtime behavior changes	Run the test commands from the plan
App/runtime/build/deploy files changed	Run the full verification commands from the plan

4. Validate the verification contract before running anything

Before executing commands, confirm the plan is specific enough.

The ## Verification section should include exact commands and expected evidence, such as:

• working directory when it matters
• env vars or prerequisites when required
• build command
• launch or serve command
• smoke-test commands such as curl, npm test, pytest, or browser checks
• URLs, ports, endpoints, files, or logs to inspect
• success criteria written as observed output or behavior

If the plan says vague things like "run the app" or "make sure it works," stop and send the work back to writing-plans to tighten the verification section.

5. Run the plan's verification commands in order

Use the commands exactly as written in the current plan.

Examples of acceptable stage-1 verification flows:

• npm run build, npm run preview, then curl http://127.0.0.1:4173/health
• pytest tests/viewer/test_session.py -q
• docker compose up -d, then curl http://localhost:3000/api/status
• start a local server and inspect the UI in a browser if the plan explicitly says to do that

When the plan requires manual observation, record what you actually saw. Do not replace it with a lighter automated check unless the plan explicitly allows that.

6. Capture evidence while running

For each verification command, note:

• the command you ran
• exit code
• relevant output
• any observed UI behavior or logs the plan required
• whether the result matched the stated success criteria

Do not summarize failed checks as "mostly passed." Report the failing step precisely.

7. Report results

State exactly what was validated and what evidence you saw.

Minimum report contents:

• changed areas that triggered validation
• verification commands executed
• observed outputs and behavior
• pass/fail status for each major check
• blockers or plan gaps, if any

Do NOT claim success without evidence.

8. Stage 2 specialization trigger

If you notice the same build, launch, and smoke-test sequence repeating across beads, that is a signal to specialize this repo-local skill.

Typical stage-2 specialization examples:

• web app: npm run build, npm run preview, HTTP smoke checks, browser inspection
• CLI tool: package build plus command-line smoke tests
• service: compose or process launch plus API health checks
• device app: app launch plus live-device smoke tests

Fix-and-Retry Loop

If validation fails or behavior is wrong, do NOT proceed to final verification. Instead:

1. Fix the code or the verification plan
2. Re-run build-and-test
3. Repeat until the checks pass

implement → build-and-test → FAIL → fix code → build-and-test → PASS → verification

Only proceed to final verification when build-and-test passes.

Skip Conditions

Do NOT trigger this skill when:

• the user explicitly says no testing is needed
• in a planner session
• only planner artifacts changed and the current plan does not require validation
