Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

author-skill scanned grade A with 1 finding 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 6d 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.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 511 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Author a skill

Take a topic and end at a linted SKILL.md draft plus a runnable fresh-session test plan. The input is a subject, not a specification — deciding the name, the boundaries, and what the skill deliberately will not cover is the work, not a precondition for it.

This skill is house-style. It encodes how this repo builds skills; the generic mechanics of the Agent Skills format are somebody else's job (see step 1).

Paths below are relative to the repo root. This skill is project scope and fires only in sessions here, but a skill it authors in skills/ deploys through ~/.claude/skills — a real directory holding one junction per skill in that tree.

An edit is immediate; a new skill needs the linker once. The asymmetry follows from those per-skill junctions. Editing an already-junctioned skill is live the moment it hits disk, for every session on this machine, committed or not. But a directory that did not exist at the last scripts/link-claude.ps1 run has no junction, so a newly authored skill is invisible everywhere — absent from the listing, and /<name> answers Unknown command. Measured 2026-09-02: land was missing from a listing of 8 junctions immediately after its SKILL.md was written, and appeared only once the linker ran. On this machine the form is ./scripts/link-claude.ps1 -SkillGroups workflow,social,meta, never bare — see root CLAUDE.md.

A platform skill is the exception that proves the rule: its group is pruned from user scope here on purpose, so a new one enters no session's payload until a -ClaudeDir run links it into one repo's .claude/.

A project-scope skill needs the linker not at all, which is the third case and the easiest to get wrong in the other direction. Nothing junctions .claude/skills/ — Claude Code reads it in place — so a new skill there is live on save for sessions in this repo, with no deploy step to forget. Do not run the linker "to pick it up"; it selects out of skills/ and will not see it. The trade is that it is live only here, which is the whole reason it is there.

Once linked, a half-drafted skill is a live half-drafted skill; finish the frontmatter before walking away.

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.
