What it does
Pre Commit is an agent skill from undeadlist/claude-code-agents. Run code quality checks and tests before committing
Its SKILL.md is about 220 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 Development, covering Code quality. The repository describes itself as: Claude Code Agents Prompt templates for Claude Code's subagent system. Run parallel code audits, automate fix cycles, get stuff reviewed. Built for the Claude Code Task tool. Not… The licence is MIT.
When your agent uses it
- Tasks that involve Code quality
Example prompts
- “/pre-commit”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 13e3d51. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Pre Commit loads about 220 tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 70 words of instructions outside code blocks.
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.
SKILL.md
The full file from undeadlist/claude-code-agents at commit 13e3d51, republished under its MIT licence (© undeadlist). 70 words, ~220 tokens.

Pre-Commit Workflow
Run before every commit to catch issues early.
Execution (Sequential)
Step 1: Code Audit
Spawn code-auditor on staged/changed files:
- Check for
anytypes, empty catch blocks, console.logs, obvious bugs - Focus only on files being committed
Step 2: Test Run
Spawn test-runner:
- Run the full test suite
- Report any failures
Step 3: Decision
- All pass -> "Ready to commit"
- Any fail -> "Fix before committing" with specific issues listed
Expected Output
# Pre-Commit Check
## Status: PASS / FAIL
### Code Quality
- [x] No new `any` types
- [x] No empty catch blocks
- [x] No console.logs in production code
### Tests
- [x] All tests pass
- [x] No regressions
