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 | $0.00010 | $0.00053 |
| Opus 5 | $0.00005 | $0.00026 |
| Sonnet 5 | $0.00002 | $0.00011 |
| Haiku 4.5 | $0.00001 | $0.00005 |
Grade A, and why
basic-skill 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 2d 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

basic-skill is a skill published in the GitHub repository skill-mill/agent-skill-porter (24 stars, last pushed 5mo ago), with no licence file. It adds 10 tokens to every session and 53 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 2026-08-30.
Other skills, from other repositories
plan-ceo-review
Mega plan review from a product/CEO perspective. Challenges premise, challenges scope, maps alternatives, reviews architecture through 11 sections, and offers an outside voice. Use when asked to "CEO review", "mega plan review", "product review this plan", or when shipping a significant new product feature.
ship
Fully automated ship workflow. Merges the base branch, runs tests, audits coverage, reviews the diff, generates a CHANGELOG entry, bumps the version, commits, pushes, and creates the PR. Use when asked to "ship", "create a PR", or "open a pull request".
plan-eng-review
Engineering plan review. Reviews a plan document for architecture, code quality, test coverage, and performance before implementation begins. Produces a coverage diagram, failure modes map, and parallelization strategy. Use when asked to "review this plan", "eng review", or "architecture review".
retro
Weekly engineering retrospective. Analyzes commit history, work patterns, and code quality metrics for the time window. Team-aware: identifies the user, then analyzes every contributor with per-person praise and growth opportunities. Use when asked for a "retro", "engineering retrospective", or "weekly summary".
review
Pre-merge code review — the single canonical review of a change before it lands. Covers BOTH diff safety/structure (SQL safety, LLM trust-boundary violations, conditional side effects) AND engineering quality (architecture fit, edge cases, test coverage, performance). Use when asked to "review this PR", "code review"…
health
Code Quality Dashboard. Runs the project's type-checker, linter, test runner, and dead-code detector, scores each category 0-10, and presents a dashboard with trends. Use when asked for a "health check", "code quality report", or "quality dashboard".
