pre-commit-check

A required validation step before staging changes, creating commits, or opening or updating pull requests. It runs the checks that apply to the changed files.

In plain words
What is it for?
Use it before git add, git commit, or pull-request work to inspect changed files, run applicable checks, fix failures, and report what was verified.
Why use it?
It catches test, formatting, or other validation failures before changes are recorded or shared for review.

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

pre-commit-check 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 2d 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.

Pre-Commit Check Skill

🛑 MANDATORY VALIDATION EXECUTOR 🛑

This skill is NOT a suggestion or checklist. It is a MANDATORY EXECUTION REQUIREMENT.

Critical Rules

  1. Invoke this skill BEFORE any git add, git commit, or PR creation
  2. Execute ALL applicable validation commands
  3. Fix ALL failures before proceeding
  4. Document what was validated in commit message
  5. Stage changes only after validation passes
  6. Present to user for final verification (do NOT auto-commit)

When to Use This Skill

MANDATORY invocation before:

  • Any git add command
  • Any git commit command
  • Any gh pr create or PR update command
  • Declaring work "complete", "done", or "finished"
  • User requests commit (even if they say "skip checks")

This skill is BLOCKING - you cannot proceed to commit without invoking it and ensuring all checks pass.

Skill Execution Protocol

When this skill is invoked, you MUST follow this exact sequence:

Step 1: Identify Changed Files

git status --short
git diff --name-only
git diff --cached --name-only

Categorize changes:

  • Backend files (*.go)
  • Frontend files (webs/*)
  • Documentation files (*.md)
  • Configuration files (config.yaml, .env.example, etc.)
  • Mixed (multiple categories)

Step 2: Execute Backend Validation (if .go files changed)

2.1 Format Check
gofmt -l $(find . -name "*.go" -not -path "./vendor/*" -not -path "./webs/*" -not -path "./.git/*")

If output is not empty:

gofmt -w $(find . -name "*.go" -not -path "./vendor/*" -not -path "./webs/*" -not -path "./.git/*")

Verify:

gofmt -l $(find . -name "*.go" -not -path "./vendor/*" -not -path "./webs/*" -not -path "./.git/*")

BLOCKING: Must return empty output (all files formatted).

2.2 Lint Check
golangci-lint run

BLOCKING: Must exit with status 0.

If fails: Read the errors, fix them, and re-run. Do NOT proceed until clean.

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.

pre-commit-check is a skill published in the GitHub repository ZeroDeng01/sublinkPro (1,599 stars, last pushed 4d ago), licensed MIT. It adds 36 tokens to every session and 2,909 once invoked, about $0.0002 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 2026-08-30.
