Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00019 | $0.00677 |
| Opus 5 | $0.00010 | $0.00338 |
| Sonnet 5 | $0.00004 | $0.00135 |
| Haiku 4.5 | $0.00002 | $0.00068 |
Grade A, and why
gen-commit-msg 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 yesterday.
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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generate Commit Message
Generate a well-formatted commit message based on staged changes.
Usage
Invoke with /gen-commit-msg or when the task matches.
Arguments:
--amend: Amend the previous commit instead of creating new--scope <scope>: Force a specific scope (e.g.,workflow,engine)
Workflow
Step 1: Analyze Changes
# Check staged files
git diff --cached --name-only
# Check staged content
git diff --cached
# Check recent commit style
git log --oneline -5
Step 2: Categorize Changes
| Type | When to Use |
|---|---|
feat |
New feature or capability |
fix |
Bug fix |
docs |
Documentation only |
refactor |
Code change without feature/fix |
test |
Adding or fixing tests |
chore |
Build, deps, config changes |
perf |
Performance improvement |
Step 3: Determine Scope
Infer scope from changed files:
src/orlib/→ infer from subdirectory (e.g.,src/auth/→auth)app/orclient/→apporclientserver/orapi/→apitest/ortests/→testdocs/→docsconfig/orconf/→configscripts/→scripts- Multiple areas → omit scope or use broader term
Step 4: Generate Message
Format:
<type>(<scope>): <subject>
<body>
[Optional sections:]
Key changes:
- change 1
- change 2
Refs: #123, #456
Rules:
- Subject: imperative mood, ~50-72 chars, no period
- Body: explain "why" not "what", wrap at 72 chars
- Key changes: bullet list of main modifications (for complex commits)
- Refs: reference issues/PRs if applicable
Step 5: Confirm and Commit
Show preview, ask user to confirm, then execute:
git commit -m "$(cat <<'EOF'
<message>
EOF
)"
Examples
Single file fix:
fix(auth): handle null user in login validation
Return proper error instead of raising exception when
user object is null during authentication.
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.

gen-commit-msg is a skill published in the GitHub repository magic3007/dotfiles (10 stars, last pushed 6d ago), licensed MIT. It adds 19 tokens to every session and 677 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.
