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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 5.1 | $0.00025 | $0.00176 |
| Opus 5 | $0.00013 | $0.00088 |
| Sonnet 5 | $0.00005 | $0.00035 |
| Haiku 4.5 | $0.00003 | $0.00018 |
Grade A, and why
needs-work 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 5d 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.
What it actually says
Needs work
This skill demonstrates the most common real-world failure, and it is a warning rather than an error because nothing here is broken — the file parses, the skill loads, and it will simply never be chosen.
The description above says what the skill is ("powerful", "flexible", "advanced") and never says when to use it. There is no trigger the router can match a user request against, so this skill sits in the library looking healthy and never fires. Its author concludes that skills don't work.
Compare with ../good-skill/SKILL.md, which ends on an explicit
"Use when the user asks to …" clause.
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.

needs-work is a skill published in the GitHub repository 0xNagato/skill-lint (0 stars, last pushed 8d ago), licensed MIT. It adds 25 tokens to every session and 176 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.

Use Slopless to review English Markdown for deterministic AI and human slop signals, including vague phrasing, formulaic prose, weak rhythm, filler, and cliches.
skillsmith
Build, lint, and evaluate agent skills that demonstrably change behaviour, instead of writing adjectives that change nothing. Use whenever the user asks to create a skill, write a SKILL.md, improve or fix an existing skill, make a skill "actually work", or evaluate whether a skill does anything. Also use when the user…
prove-it
Nothing is done until it has been run. Every claim that code works, a fix landed, or a result is correct must carry the command that proved it and that command's real output. Use whenever the user asks to implement, fix, change, refactor, debug, deploy, or verify code or config, or says "prove it", "did you test…
overllm
Find the LLM call you didn't need — your GPT call is a regex. Static, zero-config linter that flags unnecessary GPT/Claude/AI API calls a regex, the stdlib, or a library already does (parsing dates, extracting emails/JSON, sorting, classifying with fixed labels). Runs locally, no model, no API key, nothing phones…
