What it does

Build Check is an agent skill from EmeaAppGbb/spec2cloud. Verify that all project services (API and Web) build successfully. Check compilation errors, type errors, and lint warnings. Use before running tests, before deployment, after code changes, and on resume. Trigger when build verification, compilation check, or pre-test validation is needed.

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Deployment. It works with Docker. The licence is MIT.

When your agent uses it

  • Build verification
  • Compilation check
  • Pre-test validation is needed

Example prompts

  • “/build-check”

Requirements

  • Docker

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Identify services — Read azure.yaml or scan src/ for service directories
  2. Build each service — Run the source build command for each service
  3. Capture errors — Collect compilation errors, type errors, and warnings
  4. Docker build (if preparing for deployment) — Run Docker build for each Dockerfile
  5. Report — Summarize build status per service

What it can do on your machine

Read from SKILL.md and the folder at commit 8e76618. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • docker

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm and docker, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Build Check loads about 494 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 200 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~494

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Verify that all project services (API and Web) build successfully. Check compilation errors, type errors, and lint warnings. Use before running tests, before deployment, after code changes, and on resume. Trigger when build verification, compilation check, or pre-test validation is needed.

Build Check

Verify builds succeed before proceeding with tests or deployment.

Build Commands

ServiceSource BuildDocker Build
API (TypeScript)cd src/api && npm run builddocker build -f src/api/Dockerfile .
Web (Next.js)cd src/web && npm run builddocker build -f src/web/Dockerfile .

Steps

  1. Identify services — Read azure.yaml or scan src/ for service directories
  2. Build each service — Run the source build command for each service
  3. Capture errors — Collect compilation errors, type errors, and warnings
  4. Docker build (if preparing for deployment) — Run Docker build for each Dockerfile
  5. Report — Summarize build status per service

Output Format

Service: <name>
Status: PASS | FAIL
Errors: <count>
Warnings: <count>

Details:
- <file>:<line> <error message>

Notes

  • Web (Next.js) requires output: 'standalone' in next.config.ts
  • API uses TypeScript with Express

Mandatory Completion Checklist

The orchestrator MUST verify ALL of the following before marking build-check as complete:

  • Every service (API, Web) has been built — none skipped
  • Each service reports PASS or FAIL with error/warning counts
  • If any service fails to build, the failure details (file, line, message) are included
  • A partial build (one service passes, another not attempted) is reported as "incomplete" — not as PASS

BLOCKING: A build-check with any FAIL or incomplete service means the codebase is not ready for testing or deployment. The orchestrator must fix build errors before proceeding.
