What is dot-skills AGENTS.md?

Repository instructions for dot-skills, a collection of reusable instruction packs for coding agents. They describe the project structure, development workflow, and checks required before a commit.

Use them when creating or changing skills, managing experimental and published versions, and running validation, version checks, README generation, and tests.

They give contributors a shared definition of finished work and help prevent invalid skill packages or stale documentation.

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	$0.00695	$0.00695
Opus 5.5	$0.00278	$0.00278
Sonnet 5.5	$0.00139	$0.00139
Haiku 4.5	$0.00069	$0.00069

Security

Grade A, and why

dot-skills AGENTS.md 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.

The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What This Repo Is

dot-skills is a curated collection of Agent Skills (markdown rule packs + scripts).

skills/.curated/ — stable, published skills
skills/.experimental/ — new / in-progress skills. New skills start here.
Skills are authored and evolved with the dev-skill plugin: /dev-skill:new, :ingest, :evolve, :validate.
dev-skill disciplines: distillation / composition / investigation / extraction. Don't mix disciplines in one skill dir — adding a scripts/ dir to a distillation skill flips its detected discipline and breaks validation. Build a sibling skill instead.

Definition of Done — run before every commit

When asked to "run all the skill validation and audit scripts" (or before committing skill changes):

npm run validate                          # skills-ref: structural validation of every skill
node scripts/check-versions.mjs           # flag STALE/DIRTY skill versions
scripts/generate-readme-tables --update   # regenerate README skill tables
npm test                                   # skills-ref validator test suite

Fix every reported issue, then commit & push. A goal is not complete until verified.

Task Management

Always use TaskCreate for any task with 2+ steps
Break tasks into small, atomic units (carpaccio slicing)
Each task should be completable in a single focused action
Include acceptance criteria in task descriptions
Set up task dependencies with addBlockedBy/addBlocks

Development Workflow — Validator-First

Most work here is authoring markdown rule files, so the validators are the test gate (the equivalent of red-green-refactor):

Red — run the validator and read the failures:
- whole repo: npm run validate
- single skill while authoring: dev-skill's discipline-aware validate-skill.js (/dev-skill:validate <path>)
Green — fix rule files until the validator reports 0 errors.
Refactor — tighten wording / dedupe rules, then re-validate to stay green.

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.
