Archon is a workflow engine for AI coding agents that turns development processes into YAML-defined sequences with phases, validation gates, and artifacts. Developers use it to run repeatable processes such as planning, implementation, testing, code review, and pull-request creation across projects. The catalogue entries provide commands, agents, skills, hooks, instructions, and settings for working with Archon.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.01210 |
| Opus 5 | $0.00000 | $0.00605 |
| Sonnet 5 | $0.00000 | $0.00242 |
| Haiku 4.5 | $0.00000 | $0.00121 |
Grade A, and why
review-simplify 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 5d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Simplify Review — The Smallest Coherent Shape
Writing code is cheap; maintaining it and recovering option value are not. Hunt one defect: the change delivers its required outcome through more structure than that outcome needs. Preserve meaningful invariants, supported behavior, and useful foundations — not accidental implementation shape. Read-only: never modify files, commit, or post anywhere.
Read $ARTIFACTS_DIR/review/scope.md first, and the project's architecture.md if it has one. Anchor the review on the accepted work order's stated invariants, and scale depth to what the change can destroy: irreversible or destructive paths, lifecycle ownership, persisted contracts and schemas, credentials and auth boundaries, integration boundaries, and concurrency over shared state each get an explicit attempt to refute the invariant they rest on; a prose-only change gets the minimum. In light mode, verify prior simplify findings first, then examine only the delta.
Establish the contract
Start with the exact diff scope.md records, against its base. Establish the intended outcome and invariants from the accepted work order, the PR, the changed files, their tests, and direct consumers. Read beyond the diff only as far as settling a concrete question requires. Existing code is evidence, not a mandate.
Test the structural decisions
Look first for decisions that add coordination or prematurely close options:
- Data shape and ownership: Do core types match the dominant access paths? Is data copied, flattened, rebuilt, cached, or represented more than once when one owner could carry it?
- Coherent capability: Does the change deepen one useful abstraction, or spread special-case coordination across callers, layers, and schemas?
- Concurrency: If another actor changes shared state concurrently, is the answer safely "nothing"? If not, should the state be isolated instead of synchronized?
- Foundations: Would one smaller primitive make the downstream logic obvious? Remove dead weight before adding scaffold; add scaffold early only when every later phase benefits from it.
- Premature machinery: Which real supported variation requires each new state, lifecycle, wrapper, configuration surface, fallback, or extension point?
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.

review-simplify is a command published in the GitHub repository coleam00/Archon (23,374 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,210 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
