Automated summary
Reviews the working tree before a Git commit: verifies type-checking, classifies every change, and drafts a message matching the repository's style.
Strengths
- Runs git status, both diffs, and git log in parallel for a fast full inventory
- Classifies each change block (intended, refactor side-effect, pre-existing, stranger) and forces a stop on anything unexplained
- Checks secret hygiene (keys, .env files, absolute paths) before committing
- Explicitly forbids risky moves: amending pushed commits, force-push, --no-verify, empty commits
Limitations
- Assumes a Svelte project: the mandatory svelte-check step relies on the verify-svelte-check skill
- Secret detection is a manual read of the diff, with no dedicated scanning tool
- Does not cover Git repair work such as merge conflicts, history rewriting, or recovering lost commits
Use it right before committing, pushing, or opening a pull request so unrelated files and secrets don't slip into the commit.
Skip it for resolving merge conflicts, rewriting history, or recovering lost commits, which need a Git repair skill instead.
Security analysis
CautionThe skill is not malicious and includes good safeguards against force-pushing, amending published commits, bypassing hooks, and committing secrets. However, it directs agents to use powerful git/network/build tools and includes guidance that can delete untracked files or discard local changes, so it warrants caution rather than a clean safe rating.
- •Instructs running git, gh, pnpm, and svelte-check commands without declaring allowed-tools, so execution permissions may exceed metadata intent.
- •Step 2 tells the agent to delete unexpected untracked files, which can cause data loss if classification is wrong.
- •Step 3 suggests `git checkout -- file` to revert changes, which irreversibly discards local modifications.
- •Optional PR flow uses `gh pr create` and `pnpm build`, involving network/auth and build execution; legitimate but powerful.
Examples
The refactor is finished — review the working tree and commit only the changes to the FormField components, leaving anything unrelated out.Commit this work and open a PR to main with gh, showing me the list of commits it includes.Before I commit, check the staged and unstaged diffs for anything unrelated or any secrets I might be about to include.name: git-review-before-commit
description: "Review the working tree before committing to Git. Triggers on: the user asks to commit or push, a large task is complete, or a PR is about to be created. Rules: ensure svelte-check passes (see the verify-svelte-check skill), use git status to inspect all files, use git diff for staged and unstaged changes, classify pre-existing versus new changes, match the repo style (see git log --oneline -10), do not stage irrelevant files, do not commit secrets, do not amend, and do not force-push."
Skill: Git review before commit
Pre-commit checklist
Run these in parallel where independent:
git status
git diff --staged
git diff
git log --oneline -10
Steps
1. Run svelte-check first
See verify-svelte-check skill. Never commit before type-check passes.
2. git status — full inventory
- Confirm which files are staged vs unstaged
- Spot any file NOT related to the task — investigate or revert
- Spot any unexpected untracked file (test scaffolds, temp files,
.localfiles, dumps) — delete or.gitignore, don't commit
3. git diff --staged + git diff
Read all changes line by line. Classify each block:
- Intended: change addresses the user's request
- Side-effect from refactor: not directly requested but follows from the intended change
- Pre-existing: file was modified before this session — confirm not accidentally staged
- Stranger: change that doesn't fit either category. STOP, investigate.
For each stranger block:
- Revert with
git checkout -- fileif it's a scratch or accidental edit - If legitimate, mention in commit message body
4. Stage intentionally
Use git add <specific-files> rather than git add . / git add -A. Separate un-related changes into separate commits.
5. Inspect recent commits for style
git log --oneline -10
Sample repo style (from this codebase):
- Short imperative subject (~50 chars)
- Lowercase first letter
- No conventional-commits like
feat:/fix:unless the repo uses them — verify against git log - Multi-paragraph body if change has nuance, blank line between subject and body
Match style. Don't introduce a "Co-authored-by … Claude / model-name" footer unless the repo convention shows one in git log.
6. Compose commit message
Single-line example:
remove dead exports and unused props from admin form components
Multi-line example (only if nuance can't fit on one line):
remove dead exports and unused props from admin form components
- drop `placeholder`/`hint` props from FormField (no call site passes them)
- drop `confirmLabel`/`cancelLabel` props from ConfirmDialog (always default)
- drop `variant` prop from Header (always 'public')
- revert recent bind:value refactor per AGENTS.md bug #4
7. Commit (separate from push)
git commit -m "..."
Do NOT push unless the user explicitly asks.
8. (Optional) Make a PR with gh
Only when user asks. Before opening:
git log --oneline origin/main..HEADto list commits in PR- Confirm the diff still builds:
pnpm build - Open with
gh pr create --base main --title "..." --body "..." - Return the PR URL
Forbidden actions
Per repo rules + safe defaults:
git commit --amendon already-pushed commitsgit push --force/--force-with-leasewithout explicit user requestgit configmodification- Empty commits
- Skipping hooks (--no-verify)
- Interactive
-iflag
Secret hygiene
Inspect the diff for:
- API keys, tokens, JWT, secrets in env-style
- Absolute paths exposing username (
/Users/<name>//C:\Users\...) in source beyond what's already in repo - Database credentials, AWS keys, private IPs
.envfiles (they should be gitignored — verify)
If found, don't commit. Strip and ask user.
Final summary
After commit, report:
Committed: <hash-snip> "<subject>"
Files changed: <count>
Status: clean (or: working tree clean)
If asked to push:
Pushed to <remote>:<branch>
Result: <hash-snip>..<hash-snip> <branch> -> origin/<branch>
From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/git-review-before-commit-msih94xp/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/git-review-before-commit-msih94xp' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/git-review-before-commit-msih94xp/download' --output '.skill-downloads/git-review-before-commit-msih94xp/SKILL.md.part' && mv '.skill-downloads/git-review-before-commit-msih94xp/SKILL.md.part' '.skill-downloads/git-review-before-commit-msih94xp/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/git-review-before-commit-msih94xp/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
