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 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 390 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).

Repo-relative paths below are relative to the agent-config repo (C:\Repos\Personal\agent-config), not the session's cwd. ~/.claude/skills is a real directory holding one junction per skill into that repo, so this skill can fire from a session in any repo — resolve paths against agent-config regardless of where it fired.

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, never bare — see root CLAUDE.md.

A platform skill is the exception that proves the rule: fabric and powerbi are pruned from user scope here on purpose, so a new one stays unlinked by design and enters no session's payload. Nothing is broken when that happens, and no linker run changes it.

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

1. Check this is the right skill

Two routes out, both cheap to check first.

Guidance that already exists → /learn. The dividing line is whether the destination exists. /learn folds a session learning into a skill, rule, or CLAUDE.md that should already have covered it. This skill creates guidance that has no home yet. A learning that arrives as "the fabric-cicd skill was wrong about X" is /learn work even if the fix is large.

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.
