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.

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 | $0.00678 |
| Opus 5.5 | $0.00005 | $0.00271 |
| Sonnet 5.5 | $0.00002 | $0.00136 |
| Haiku 4.5 | $0.00001 | $0.00068 |
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 4d 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 registerApiRoutes in packages/server/src/routes/api.ts for the API route structure: it calls one registrar per area, each in an api.<area>.ts module beside it.
7. Check Recent Frontend Activity
!git log -8 --oneline -- packages/web/ packages/server/src/adapters/web/
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 (23,752 stars, last pushed today), licensed MIT. It adds 12 tokens to every session and 678 once invoked, about $0.0000 per session on Opus 5.5. 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.
Other commands, from other repositories
fix-issues
Diagnose, reproduce, then fix reproducible open GitHub issues in parallel: one clean worktree/issue; symlink build artifacts to avoid rebuilds.
review-prs
Parallel PR triage: decide merge-worthiness, prepare rebased worktrees, fix blockers, return them for human merge.
triage
Classify/label newly opened GitHub issues missing labels.
release
Release all packages at specified version.
cleanup
Autonomous cleanup-loop iteration: discover ONE target → complete execution → verify → report. Runs stateless: derive from current tree; assume prior runs left it consistent.
