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 5.1 | $0.00187 | $0.02148 |
| Opus 5 | $0.00093 | $0.01074 |
| Sonnet 5 | $0.00037 | $0.00430 |
| Haiku 4.5 | $0.00019 | $0.00215 |
Grade A, and why
update-docs 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 12d 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.

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.

update-docs is a skill published in the GitHub repository lukaskellerstein/claude-my-marketplace (3 stars, last pushed 1mo ago), with no licence file. It adds 187 tokens to every session and 2,148 once invoked, about $0.0009 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.
Other skills, from other repositories
fp-yoohoo
Terminal-recall mode. Reference for fp-yoohoo, the plugin that brings the terminal window to the foreground when Claude Code stops and waits on a human: a permission prompt, a question dialog, a plan to approve. Explains what it hooks, which desktops it can raise a window on, how the already-focused guard works, and…
fp-minify
Comment-concision mode. Shapes the code the model writes so comments earn their place (a non-obvious why, or meaning a name can't hold: config, units, magic numbers, constraints) and stay short. Hard one-line cap on inline comments, and a density bar, so most functions carry none. Measurements, rejected alternatives…
fp-barbeque
Understanding-first mode. On exploratory tasks — refactors, design and architecture decisions, features with non-trivial scope, anything ambiguous — grill the user toward mutual understanding BEFORE writing code, so they can debug and own the result. Sets a prior at the task edge; the model decides whether a task…
fp-honesty
Surfaces the epistemic basis of load-bearing claims — tags each with verified / inferred / recalled / guess and ends with a one-line basis tally. Pure annotation: it never changes what you decide or do. Active every response while on. Use whenever the user says "fp-honesty", "honesty mode", "show your confidence"…
fp-sicem
Readable-prose mode ("sic 'em-dash"). In the prose you write or revise (READMEs, docs, markdown, PR and commit bodies) it defaults the em-dash out of existence, replacing it and its cousins (the semicolon, the colon used for drama, and long dash-parentheticals) with the connector that actually fits: a period, a comma…
update-component-reference
This skill should be used when the user wants to add components (commands, agents, skills, hooks, or MCP servers) to the Component Reference section of the website.
