AAS Core is a local control plane for coding agents that lets them search a large catalogue of skills, choose a stack, validate it, and create a reproducible plan. It is used to assemble and review agent workflows through its CLI, local MCP server, catalogue, plugins, and Workbench. The catalogue add-ons provide the skills, plugins, bundles, and workflows that AAS Core helps agents select and validate.

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 | $0.01931 | $0.01931 |
| Opus 5.5 | $0.00772 | $0.00772 |
| Sonnet 5.5 | $0.00386 | $0.00386 |
| Haiku 4.5 | $0.00193 | $0.00193 |
Grade A, and why
agentic-awesome-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 22d 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
Project Structure & Module Organization
This repository publishes an installable library of agent skills and plugin bundles. Canonical skill sources live in skills/<skill-id>/SKILL.md; use lowercase, hyphenated skill IDs. Mirrored plugin distributions live under plugins/. Contributor and user docs live in docs/; localized docs live in docs_zh-CN/ and docs/vietnamese/. Maintenance scripts and tests are in tools/scripts/ and tools/scripts/tests/. The hosted catalog app is in apps/web-app/. Registry outputs such as CATALOG.md, skills_index.json, and data/catalog.json are generated artifacts. Editorial inputs in data/ remain source files; use tools/scripts/generated_files.js for the exact generated-file classification.
Build, Test, and Development Commands
npm ci: install root dependencies for scripts and validation.npm run validate: validate skill frontmatter, required sections, and schema rules.npm run security:docs: run safety checks for command, install, credential, and network guidance.npm run test: run the repository script test suite.npm run build: regenerate core indexes and build the catalog data.npm run app:install: installapps/web-appdependencies.npm run app:dev: start the local Vite catalog app.npm run app:build: build and prerender the catalog app.
Before PRs, run npm run validate && npm run test && npm run security:docs.
Coding Style & Naming Conventions
Use Markdown for skills and docs, JavaScript/Node for most tooling, and Python for audits and sync helpers. Keep skill directories lowercase with hyphens, for example skills/my-awesome-skill/SKILL.md. Start new skills from docs/contributors/skill-template.md; include frontmatter, ## When to Use, examples, and limitations. Keep generated-file edits out of community PRs unless doing maintainer release or sync work.
Testing Guidelines
Tests live mainly in tools/scripts/tests/ and use Node assertions or Python unittest. Name new tests after the behavior under test, for example installer_filters.test.js or test_validate_skills_strict.py. Run targeted tests during development, then run the relevant npm scripts above. Web app changes should also run npm run app:test or npm run app:test:coverage.
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.
