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 | $0.00053 | $0.00603 |
| Opus 5 | $0.00026 | $0.00302 |
| Sonnet 5 | $0.00011 | $0.00121 |
| Haiku 4.5 | $0.00005 | $0.00060 |
Grade A, and why
commit 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Git Commit
Group all unstaged/untracked changes into atomic commits — one commit per logical concern. A single concern is just the degenerate case: one commit. Never push — pushing belongs to the /ship cycle.
Message Style
Match the repo's existing commit patterns from log.
- Extreme concision — sacrifice grammar for brevity
- Focus on "why" not "what"
- Imperative mood
- Conventional commits when the repo uses them (
feat/fix/refactor/docs/chore+ scope)
Workflow
- Review full diff and status
- Analyze recent commit style from log
- Identify logical groups among the changed files. Common groupings:
- Feature or bug fix (src files implementing one thing)
- Tests for that feature
- Config changes (
package.json,tsconfig, etc.) - Formatting-only changes (no logic change)
- Docs / README updates
- Asset changes (images, fonts, public files)
- For each group:
a. Stage only those files explicitly by name (never
git add .or-A) b. Write a commit message matching repo style c. Commit with HEREDOC format d. Rungit statusto confirm staging is clean before the next group - Run
git statusto verify a clean working tree
Grouping Rules
- Formatting-only changes (whitespace, quotes, indentation) go in their own commit, separate from logic changes
- If a file has both logic and formatting changes, keep them together in the logic commit
- Tests and the code they test can share a commit
Examples
Single concern — one commit:
git add src/auth.ts
git commit -m "fix: null check in login handler"
Multiple concerns — split:
git add src/components/SearchBar.tsx src/hooks/useSearch.ts
git commit -m "feat: add search bar component"
git add README.md
git commit -m "docs: document search usage"
Rules
- NEVER push — pushing belongs to
/ship - NEVER
git add .or-A— stage explicitly by name - NEVER amend unless requested
- NEVER skip hooks
- NEVER commit secrets
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.

commit is a skill published in the GitHub repository helderberto/agent-skills (13 stars, last pushed 10d ago), licensed MIT. It adds 53 tokens to every session and 603 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 2026-08-30.
Other skills, from other repositories
code-review-and-quality
Conducts multi-axis code review. Use before merging any change. Use when reviewing code written by yourself, another agent, or a human. Use when you need to assess code quality across multiple dimensions before it enters the main branch.
constraint-driven-development
Establishes a project's quality bar as a written contract and stops agents quietly lowering it. Interviews the user on which dimensions matter, supplies sane default thresholds when they have no number in mind, records everything in CONSTRAINTS.md, and watches the diff for a weakened bar — new @ts-ignore or…
performance-optimization
Optimizes application performance across frontend, backend, queries, and databases. Use when performance requirements exist, when you suspect performance regressions, when Core Web Vitals or load times need improvement, when N+1 query patterns need fixing, or when profiling reveals bottlenecks.
api-and-interface-design
Guides stable API and interface design. Use when designing APIs, module boundaries, or any public interface. Use when creating REST or GraphQL endpoints, defining type contracts between modules, or establishing boundaries between frontend and backend.
doubt-driven-development
Subjects every non-trivial decision to a fresh-context adversarial review before it stands. Use when correctness matters more than speed, when working in unfamiliar code, when stakes are high (production, security-sensitive logic, irreversible operations), or any time a confident output would be cheaper to verify now…
test-driven-development
Drives development with tests. Use when implementing any logic, fixing any bug, or changing any behavior. Use when you need to prove that code works, when a bug report arrives, or when you're about to modify existing functionality.
