Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.02532 |
| Opus 5 | $0.00030 | $0.01266 |
| Sonnet 5 | $0.00012 | $0.00506 |
| Haiku 4.5 | $0.00006 | $0.00253 |
Grade A, and why
checkin-assistant 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 404 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Checkin Assistant
Language: English | 繁體中文
Version: 1.0.0 Last Updated: 2026-01-12 Applicability: Claude Code Skills
Purpose
This skill guides developers through pre-commit quality gates, ensuring every commit maintains codebase stability and follows best practices.
Note: This skill focuses on when and how to commit. For code review during PR, see Code Review Assistant.
Quick Reference (YAML Compressed)
# === CORE PHILOSOPHY ===
every_commit_should:
- "Be a complete logical unit of work"
- "Leave codebase in working state"
- "Be reversible without breaking functionality"
- "Contain its own tests (for new features)"
- "Be understandable to future developers"
# === MANDATORY CHECKLIST ===
checklist:
build:
- "Code compiles (zero errors)"
- "Dependencies satisfied"
verify: "Run build command, exit code 0"
tests:
- "All existing tests pass (100%)"
- "New code has tests"
- "Coverage not decreased"
verify: "Run test suite, check coverage"
quality:
- "Follows coding standards"
- "No code smells (methods≤50, nesting≤3, complexity≤10)"
- "No hardcoded secrets"
- "No security vulnerabilities"
verify: "Run linter, security scanner"
docs:
- "API docs updated"
- "README updated (if needed)"
- "CHANGELOG updated (user-facing changes → [Unreleased])"
workflow:
- "Branch naming correct (feature/, fix/, docs/, chore/)"
- "Commit message formatted (conventional commits)"
- "Synced with target branch"
# === NEVER COMMIT WHEN ===
blockers:
- "Build has errors"
- "Tests are failing"
- "Feature incomplete (would break functionality)"
- "Contains WIP/TODO in critical logic"
- "Contains debugging code (console.log, print)"
- "Contains commented-out code blocks"
# === COMMIT TIMING ===
good_times:
- completed_unit: "Feature fully implemented with tests"
- bug_fixed: "Bug fixed with regression test"
- independent_refactor: "Refactoring complete, all tests pass"
- runnable_state: "Code compiles, app can run"
bad_times:
- "Build failures"
- "Test failures"
- "Incomplete features"
- "Experimental code with scattered TODOs"
# === GRANULARITY ===
ideal_commit:
files: "1-10 (split if >10)"
lines: "50-300"
scope: "Single concern"
split_rules:
combine: ["feature + its tests", "tightly related multi-file changes"]
separate: ["Feature A + B", "refactor + new feature", "bugfix + incidental refactor"]
# === SPECIAL SCENARIOS ===
emergency_leave:
recommended: "git stash save 'WIP: description'"
alternative: "Create wip/ branch"
prohibited: "Commit WIP directly on feature branch"
experimental:
branch: "experiment/topic-name"
rules: "Free commits (no strict format)"
success: "Clean up, squash, merge to feature"
failure: "Document lessons, delete branch"
hotfix:
branch: "hotfix/issue-name from main"
rules: "Minimize changes, only fix the problem"
message: "fix(scope): [URGENT] description"
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.

checkin-assistant is a skill published in the GitHub repository ValorVie/custom-skills (5 stars, last pushed 4d ago), licensed MIT. It adds 59 tokens to every session and 2,532 once invoked, about $0.0003 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 2026-09-03.
