A routing and maintenance guide for a collection of coding skills. It keeps one AGENT.md file that tells the system which skill to use for each task.

Review a skill collection, check its metadata, find skills that could be merged, and flag skills that need repair, promotion, or removal.

It reduces duplicated instructions and helps tasks reach the right skill with only the necessary context. It also identifies inconsistent, overlapping, or outdated skill definitions.

Made for: Claude Code.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00001	$0.00893
Opus 5.5	$0.00000	$0.00357
Sonnet 5.5	$0.00000	$0.00179
Haiku 4.5	$0.00000	$0.00089

Measured 2mo ago against content hash ab2e5c3f1c68, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

guide 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 2mo 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

guide — Guidance Meta-Skill

What

Maintain the single Schema file AGENT.md so that execute always routes to the right skill with the minimum information possible.

Guide does not create domain knowledge; it organizes and routes.

When to use

✅ distill has just done Create / Merge / Deprecate.
✅ User asks to "tidy up skills / find merge candidates".
✅ Periodic review (e.g. every N completed tasks).

When NOT to use

❌ Domain questions themselves (those belong to execute).
❌ Internal edits to a single SKILL.md (those belong to distill).

How (SOP)

1. Scan the skill set

ls skills/*/SKILL.md

Parse only the front-matter of each file (skip the body). Collect: name, status, triggers, dependencies, updated.

2. Consistency checks (Schema guard)

Check	Action
Missing front-matter field	Mark as `malformed`, notify distill to fix
`name` differs from directory name	Error, require fix
`triggers` fully overlap another skill	Suggest Merge
`status: experimental` for > 2 reuse cycles with no promotion	Suggest promote or deprecate
`status: deprecated` kept for > 1 cycle	Suggest deletion
`dependencies` point to a non-existent skill	Error

3. Update `AGENT.md`

May edit only:

§2.1 / §2.2 registry (add/remove/modify rows).
§7 changelog (append a line).

All other sections (loop definition, contract, anti-patterns) are stable; changes require explicit user confirmation.

4. Produce a diff summary

After each guide run, report to user:

Added:       skills/xxx   (from distill, experimental)
Promoted:    skills/yyy   experimental → active
Deprecated:  skills/zzz   (90 days cold)

5. Reverse-notify

If a skill has weak triggers (never matches), reverse-suggest distill to rewrite them.

Examples

After distill creates `debug-cuda-oom`

Scan finds a new directory skills/debug-cuda-oom.
Front-matter is valid.

Append to AGENT.md §2.2:

| debug-cuda-oom | skills/debug-cuda-oom/SKILL.md | CUDA, OOM, VRAM | experimental |

Append to AGENT.md §7: - 2026-05-02 — registered debug-cuda-oom (experimental)
Report to user.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
