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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00012 | $0.00654 |
| Opus 5 | $0.00006 | $0.00327 |
| Sonnet 5 | $0.00002 | $0.00131 |
| Haiku 4.5 | $0.00001 | $0.00065 |
Grade A, and why
prime-frontend 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 6d 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.

Prime Frontend: Web UI Orientation
Objective
Orient on the React frontend (packages/web/) before working on Web UI code. Also covers the
server-side Web adapter that feeds data to the UI via SSE.
Process
1. Understand the Frontend Stack
Read packages/web/package.json for exact dependency versions (React 19, Vite 6, TanStack
Query v5, React Router v7, Tailwind v4, shadcn/ui).
2. Understand the Route and Layout Structure
Read packages/web/src/App.tsx for routes, layout, QueryClient config, and ErrorBoundary.
List route pages:
!ls packages/web/src/routes/
List component directories:
!ls packages/web/src/components/
3. Understand Component Organization
List each component subdirectory to understand the breakdown (chat, conversations, dashboard,
layout, sidebar, ui, workflows):
!ls packages/web/src/components/chat/ packages/web/src/components/workflows/ packages/web/src/components/layout/
4. Understand Data Fetching
Read packages/web/src/lib/api.ts — API client with REST functions and SSE base URL logic.
Read hooks in packages/web/src/hooks/:
!ls packages/web/src/hooks/
Read packages/web/src/hooks/useSSE.ts for the SSE streaming pattern.
5. Understand Theme and Styling
Read packages/web/src/index.css for the Tailwind v4 @theme inline {} block — this is the
single source of truth for colors, fonts, and design tokens (dark theme only, blue accents,
Inter + JetBrains Mono fonts). Note: uses @import "tailwindcss" (not @tailwind directives).
6. Understand the Server-Side Web Adapter
Read packages/server/src/adapters/web/ files — the Web adapter uses SSE for streaming and
sendStructuredEvent() for rich tool call data.
!ls packages/server/src/adapters/web/
Read packages/server/src/routes/api.ts first 80 lines for API route structure.
7. Check Recent Frontend Activity
!git log -8 --oneline -- packages/web/ packages/server/src/adapters/web/
Output
Summarize (under 200 words):
Route Structure
- List each route page and its URL path
- Note active route and layout components
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.

prime-frontend is a command published in the GitHub repository coleam00/Archon (23,387 stars, last pushed 3d ago), licensed MIT. It adds 12 tokens to every session and 654 once invoked, about $0.0001 per session on Opus 5. 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.

Autonomous cleanup-loop iteration: discover ONE target → complete execution → verify → report. Runs stateless: derive from current tree; assume prior runs left it consistent.
