speckit.checker

speckit.checker is a skill for Claude Code, Codex from wedabro/bro-skills. It costs 19 tokens per session (661 once invoked), scanned A, original, MIT.

A static-analysis workflow that checks source code and project configuration for coding, security, performance, build, type, and lint problems. Static analysis examines code without running the application.

In plain words
What is it for?
Use it to run applicable compile, type-check, lint, security, and performance checks and report unavailable checks separately.
Why use it?
It avoids guessing which checks apply by first identifying the project's language, tools, containers, and documented commands.

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.checker 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 10d 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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

🎯 Mission

Detect coding-standard violations, security issues, and performance anti-patterns using commands appropriate to the actual project stack. MUST run applicable checks — do not claim a check passed from visual review.

📥 Input

  • Source code and dependency manifests
  • .agents/memory/constitution.md (coding standards)
  • .agents/project.json and documented build/test commands
  • Docker files when the project is containerized

📋 Protocol

Phase 1: Capability Discovery

  1. Read project configuration and dependency manifests.
  2. Detect language, package manager, containerization, services, and available build/lint/type-check scripts.
  3. Build an applicability table. Mark unavailable checks N/A with a reason; never treat N/A as a pass or failure.

Phase 2: Compile, Type, and Lint Checks

  • Run the repository-defined compile, type-check, and lint commands.
  • If the constitution requires container execution, run them in the matching service. Otherwise use the project's documented runtime.
  • Compiler/type errors are 🔴 CRITICAL. Lint severity follows project policy.
  • Do not assume TypeScript, npm, a monorepo, or fixed service names.

Phase 3: Container Checks (When Applicable)

  • Validate every discovered Compose file with docker compose ... config.
  • Verify Dockerfile COPY sources, non-root production runtime, health checks, environment-driven published ports, and no production source shadowing.
  • If the project is not containerized, record this phase as N/A.

Phase 4: Configuration and Security

  • Scan source and tracked files for likely secrets, unsafe URL/endpoint literals, injection sinks, unsafe HTML, dynamic evaluation, and SQL concatenation.
  • Exclude generated/vendor directories and report redacted locations only.
  • Treat intentional public URLs, documentation links, and schema identifiers according to project policy rather than flagging every https:// literal.

Phase 5: Stack-Specific Integrity

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.

speckit.checker is a skill published in the GitHub repository wedabro/bro-skills (2 stars, last pushed 14d ago), licensed MIT. It adds 19 tokens to every session and 661 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
