# Archon for Claude Code: what it does and how to install it > coleam00/archon is the Claude Code plugin from the Archon project, an open-source harness for making AI coding deterministic and repeatable. It has 46 components: 14 skills, 13 agents, 19 commands. About a third only work on Archon's own codebase; the rest cover code review, root cause analysis, and browser automation on any project. Canonical: https://www.flowy.sh/plugins/coleam00-archon/guide Published: 2026-10-29 Updated: 2026-10-29 Author: Flowy ## What is Archon? `coleam00/archon` is the source repository for Archon, described in its own summary as the first open-source harness builder for AI coding, built to make AI coding deterministic and repeatable rather than a one-off chat session (23,273 GitHub stars). The Claude Code plugin inside that repository is not the Archon product wrapped as a skill. It is 46 components, 14 skills, 13 agents, and 19 commands, and most of them exist to help someone work on Archon's own codebase, workflows, or bugs. Archon itself, per `archon-dev`'s own description, is a remote coding agent: a platform run through a CLI called `archon`, with its own frontend, backend, workflow engine, and isolation layer. This plugin is the working set coleam00 built while shipping that platform, published rather than kept private. ## Who should use Archon? Split the 46 components by what they assume before you install it. About a third name Archon, its CLI, or one of its internal subsystems directly, and only do something with Archon's own source checked out. The rest never mention Archon at all: general-purpose engineering skills, agents, and commands that read the same on Archon or on your own repository. ## Which Archon components only work on the Archon project? The `archon` skill runs and creates Archon workflows and commands and manages Archon's own configuration. `manage-run` inspects, monitors, starts, approves, and controls Archon workflow runs through the `archon` CLI over bash. `archon-dev` is the primary skill for developing Archon's own code and routes to specialized guides depending on what you're trying to do. Five commands prime an agent with one slice of Archon's own codebase before you touch it: `prime` for the whole thing, `prime-frontend` for the React web UI, `prime-backend` for the core and server, `prime-workflows` for the workflow engine, and `prime-isolation` for its isolation system and git operations. `plan-feature` writes an implementation plan for an Archon feature, and `execute` runs an existing Archon plan file. Validation and release get their own components. `validate` runs Archon's validation suite with a report per level, and `validate-2` is broader: an end-to-end check of the platform covering Docker, a test adapter, the database, and a full GitHub workflow run. `validate-ui` audits the Archon web interface through browser automation. `release` cuts a patch, minor, or major release from the dev branch, writes the changelog, and opens the PR to main, and `test-release` then verifies that the released `archon` binary works through a specific install path. `replicate-issue` spins up Archon and re-tests a reported GitHub issue's symptoms with browser automation. ## Which Archon components work on any codebase? For review and quality: `code-reviewer` and the `code-review` command check guideline compliance and bugs, `code-review-fix` fixes what a review found, `rulecheck` and its companion `rulecheck-agent` scan for rule violations and fix the highest-impact ones in an isolated worktree before opening a PR, `silent-failure-hunter` looks for swallowed errors and bad fallbacks, `type-design-analyzer` rates a type's encapsulation and invariants, `code-simplifier` proposes simplifications without changing behavior, and `comment-analyzer` catches comments that no longer match the code. For understanding a codebase you didn't write: `codebase-explorer` finds where code lives and how it's built, `codebase-analyst` traces data flow with file and line references, `docs-impact` flags documentation a change left stale, and `web-researcher` searches for current docs and APIs and cites its sources. For a bug end-to-end: `rca` documents a root cause for a GitHub issue, `implement-fix` builds the fix from that document, `triage` and `triage-agent` apply type, effort, priority, and area labels to issues, and `pr-test-analyzer` rates a pull request's test coverage before it ships. Rounding it out: `commit` writes an atomic commit, `handoff` writes a session handoff document, `execution-report` reflects on completed work in a report, `review-doc` and `system-review` critique a document or a finished implementation against its plan, `create-command` generates new slash commands, `save-task-list` keeps a task list across sessions, `sdk-verifier` checks a TypeScript Agent SDK app before deployment, `docker-extend` personalizes the Docker dev container, and `remotion-best-practices` covers Remotion video work in React. ## Why do agent-browser and playwright-cli look identical? `agent-browser` and `playwright-cli` carry the exact same description in what Flowy indexed: automating browser navigation, form filling, screenshots, and data extraction for web testing. The fact pack does not explain why the plugin ships both under separate names, so treat them as one browser automation capability reachable two ways rather than two different tools. ## How do I install Archon in Claude Code? Flowy indexes `coleam00/archon` from its public GitHub repository. It does not host, bundle, or modify any of these 46 components, so what you get is whatever the repository ships. Install from [the install card on the listing page](https://www.flowy.sh/listings/coleam00-archon#install), and check whether the Archon-specific or the general-purpose half is the one you actually need.

It is the plugin published inside the Archon project's own GitHub repository, coleam00/archon. Archon describes itself as an open-source harness for making AI coding deterministic and repeatable, and this plugin is the working set of 14 skills, 13 agents, and 19 commands the project uses to build and ship itself. ### Do I have to be contributing to Archon to get value from this plugin? No, but about a third of the 46 components only make sense if you are. Anything naming Archon, its `archon` CLI, or an internal subsystem like the frontend, backend, workflow engine, or isolation layer only works against Archon's own source. The rest, including `code-reviewer`, `silent-failure-hunter`, `rca`, and the browser automation skills, are general purpose and work on any codebase. ### What is the difference between validate and validate-2? `validate` runs Archon's own validation suite with a report broken out per level. `validate-2` is broader: an end-to-end check of the platform that also covers Docker, a test adapter, the database, and a full GitHub workflow run. Neither replaces the other, they check different scopes of the same platform. ### What do agent-browser and playwright-cli actually do? Both `agent-browser` and `playwright-cli` carry the exact same description in what Flowy indexed: automating browser navigation, form filling, screenshots, and data extraction for web testing. The fact pack does not explain why the plugin ships both under separate names, so treat them as one browser automation capability reachable under two names rather than two different tools. ### How many skills, agents, and commands does coleam00/archon ship? Flowy indexes 46 components for coleam00/archon: 14 skills, 13 agents, and 19 commands. There are no MCP servers and no hooks in what the crawler found, so everything here runs as a skill invoked by intent, an agent you dispatch, or a command you type directly. ## Related - [The listing page](https://www.flowy.sh/listings/coleam00-archon): Install command, components and repository - [Alternatives to this plugin](https://www.flowy.sh/alternatives/coleam00-archon): Peers in its category, ranked by stars - [The Claude Code plugin marketplace](https://www.flowy.sh/marketplace/plugins): How plugins install, and every plugin in the index - [Paperclip for Claude Code: what it does and how to install it](https://www.flowy.sh/plugins/paperclipai-paperclip/guide): another plugin guide - [superpowers for Claude Code: what it does and how to install it](https://www.flowy.sh/plugins/superpowers-flow/guide): another plugin guide
