speckit.validate

speckit.validate is a skill for Claude Code, Codex from wedabro/bro-skills. It costs 14 tokens per session (591 once invoked), scanned A, original, MIT.

An implementation checker that compares the full codebase with a project specification and its task plan. It discovers the project’s build, test, runtime, and health-check commands before verifying them.

In plain words
What is it for?
Use it to verify completed tasks, success criteria, source code, dependencies, builds, and runtime behavior. Checks that do not apply are marked separately from successful checks.
Why use it?
It provides a final check that required work is complete and that applicable builds, tests, and running services actually work before deployment.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

speckit.validate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

🎯 Mission

Check whether the ENTIRE implementation meets spec.md or not — final gate before deploying.

📥 Input

  • All artifacts: spec.md, plan.md, tasks.md
  • Source code (implementation)
  • .agents/memory/constitution.md
  • .agents/project.json, dependency manifests, and documented verification commands

📋 Protocol

  1. Tasks Completion: All tasks in tasks.md have [X] ?
  2. Success Criteria: All SCs in spec.md passed?
  3. Capability Discovery:
    • Detect project type, language, package manager, containerization, configured services, build/test commands, and health checks.
    • Produce an applicability table. A non-applicable check is N/A, not PASS.
  4. Build Verification (MUST run applicable commands):
    • Run the repository-defined build/type/lint commands.
    • Use the matching container service when the constitution requires Docker.
    • For non-Docker projects, use the documented project runtime.
    • Any applicable build failure → ❌ BLOCKED.
  5. Runtime Verification (when the project has a runtime):
    • Start the documented runtime or discovered Compose configuration.
    • Wait using health/retry behavior with a bounded timeout; do not use a fixed sleep as proof of readiness.
    • Inspect failing service/application logs immediately.
  6. Health Check (when configured):
    • Read health endpoints and ports from project configuration or environment.
    • Verify the expected status/body. Do not assume web/admin/API services.
  7. Tests and Success Criteria:
    • Run the configured test suite and verify each spec success criterion with evidence. Missing required evidence → ❌ BLOCKED.
  8. Constitution Check: No rules violated?
  9. Final Verdict:
    🏁 VALIDATION REPORT
    ═══════════════════════
    Tasks:        15/15 ✅
    Build:        PASS ✅
    Runtime:      N/A (library project)
    Health:       N/A (no network service)
    Tests:        PASS ✅
    Constitution: PASS ✅
    ───────────────────────
    VERDICT: ✅ READY FOR DEPLOY

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
