Archon CLI Skill

Archon is a remote agentic coding platform that runs AI workflows in isolated git worktrees. This skill teaches you how to run workflows, create new workflows and commands, and manage Archon configuration.

Available Workflows (live)

!archon workflow list 2>&1 || echo "Archon CLI not installed. Read guides/setup.md to set it up."

Routing

Determine the user's intent and dispatch to the appropriate guide:

Intent	Action
Setup / install / "how to use"	Read guides/setup.md — interactive setup wizard
Config / settings	Read guides/config.md — interactive config editor
Initialize .archon/ in a repo	Read references/repo-init.md
Create a workflow	Read references/workflow-dag.md — the complete workflow authoring guide
Quick parameter lookup — which field works on which node type	Read references/parameter-matrix.md — master matrix, intent-based lookup, silent-failure catalog
Advanced features (hooks/MCP/skills)	Read references/dag-advanced.md
Create a command file	Read references/authoring-commands.md
Variable substitution reference	Read references/variables.md
CLI command reference	Read references/cli-commands.md
Run an interactive workflow	Read references/interactive-workflows.md — transparent relay protocol
Workflow good practices / anti-patterns	Read references/good-practices.md — read before designing a non-trivial workflow
Troubleshoot a failing / stuck workflow	Read references/troubleshooting.md — log locations, common failure modes
Run a workflow (default)	Continue with "Running Workflows" below

If the intent is ambiguous, ask the user to clarify.

Richer Context: archon.diy

The references in this skill are a distilled subset. The full, canonical docs live at archon.diy (Starlight site from packages/docs-web/). If the skill's reference pages don't cover what you need — an edge case, a worked example, a diagram, a deeper section on a feature — fetch the matching page from archon.diy.

When to reach for the live docs

• You need an end-to-end example that's longer than what the skill shows (e.g. full patterns for hooks, MCP config, sandbox schema, approval flows)
• You're explaining a concept to the user and want the most readable framing (the book/ series is written as a tutorial, not a reference)
• You hit a feature the skill only mentions in passing (e.g. agents: inline sub-agents, advanced Codex options, the full SyncHookJSONOutput schema)
• The user asks "where is this documented?" — point them at the archon.diy URL, not a skill file path

Precedence

This skill's reference pages are the primary source for routine workflow authoring, CLI use, and setup. Reach for archon.diy when the skill is incomplete for your case — don't go to the live docs first by default (skill refs load into context faster and are tuned for agents).

Running Workflows

Core Command

archon workflow run <workflow-name> --branch <branch-name> "<message>"

CRITICAL RULES:

1. Always run in background — Archon workflows are long-running. Always invoke the Bash tool with run_in_background: true. Use /tasks or the TaskOutput tool to check on progress.

2. Always use worktree isolation — Use the --branch flag unless the user explicitly requests otherwise. This creates an isolated environment so Archon works without affecting the main branch.

3. One workflow per shell — Each workflow blocks its shell. Run multiple workflows as separate background tasks.

Isolation Modes

Mode	Flag	When to Use
Worktree (Default)	--branch <name>	Always use this unless told otherwise
Custom start-point	--branch <name> --from <base>	Start from a specific branch
Direct checkout	--no-worktree	Only if user explicitly requests no isolation
Resume failed run	--resume	Resume from the last failure point

Workflow Selection

Match the user's intent to a workflow from the live list above. Common patterns:

User Intent	Typical Workflow	Branch Pattern
"Fix issue #X" / "Resolve bug"	archon-fix-github-issue	fix/issue-{N}
"Review PR #X" / "Full review"	archon-comprehensive-pr-review	review/pr-{N}
"Quick review PR #X"	archon-smart-pr-review	review/pr-{N}
"Validate PR #X" / "Check PR"	archon-validate-pr	review/pr-{N}
"Implement from plan"	archon-feature-development	feat/{name}
"Plan and implement feature"	archon-idea-to-pr	feat/{name}
"Execute plan file"	archon-plan-to-pr	feat/{name}
"Run ralph" / "Implement PRD"	archon-ralph-dag	feat/{name}
"Resolve conflicts"	archon-resolve-conflicts	resolve/pr-{N}
"Create issue" / "File a bug"	archon-create-issue	issue/{name}
"Review issue #X fully"	archon-issue-review-full	review/issue-{N}
"Refactor safely"	archon-refactor-safely	refactor/{name}
"Architecture review"	archon-architect	review/{name}
"PIV loop" / "guided dev"	archon-piv-loop ⚡	piv/{name}
"Create a PRD" / "interactive PRD"	archon-interactive-prd ⚡	prd/{name}
General / debugging

⚡ = Interactive workflow — requires the transparent relay protocol. Read references/interactive-workflows.md before running.

If no specific workflow matches, use archon-assist as the fallback. The live workflow list above is always authoritative — it may include workflows not in this table.

Multi-Issue Invocation

When the user mentions multiple issues, PRs, or tasks — run each as a separate background task:

# Each gets its own worktree — they won't conflict
archon workflow run archon-fix-github-issue --branch fix/issue-10 "Fix issue #10"
archon workflow run archon-fix-github-issue --branch fix/issue-11 "Fix issue #11"
archon workflow run archon-fix-github-issue --branch fix/issue-12 "Fix issue #12"

Never combine multiple issues into a single command.

Authoring Quick Start

Archon uses a single workflow format: nodes (DAG). Workflows are YAML files in .archon/workflows/.

IMPORTANT: The examples below are starting points. Always design the workflow around what the user actually needs — the number of nodes, their types, dependencies, and configuration should match the user's requirements, not these templates.

Workflow Structure

name: my-workflow
description: What this workflow does
provider: claude          # Optional: 'claude', 'codex', 'pi', ... (default: from config)
model: medium             # Optional: tier keyword (small|medium|large), @alias, or literal model
nodes:
  - id: first-node
    command: my-command    # Loads .archon/commands/my-command.md
  - id: second-node
    prompt: "Use the output: $first-node.output"
    depends_on: [first-node]

Node Types

Each node has exactly ONE of: command, prompt, bash, script, loop, loop_group, approval, or cancel.

Command node — runs a .archon/commands/*.md file:

- id: investigate
  command: investigate-issue

Prompt node — inline AI prompt:

- id: classify
  prompt: "Classify this issue: $ARGUMENTS"
  model: haiku
  allowed_tools: []

Bash node — shell script, no AI, stdout captured as output:

- id: fetch-data
  bash: "gh issue view 42 --json title,body"
  timeout: 15000

Script node — TypeScript/JavaScript (via bun) or Python (via uv), no AI, stdout captured as output:

- id: transform
  script: |
    const raw = process.argv.slice(2).join(' ') || '{}';
    console.log(JSON.stringify({ parsed: JSON.parse(raw) }));
  runtime: bun           # 'bun' (.ts/.js) or 'uv' (.py) — REQUIRED
  timeout: 30000         # Optional, ms, default 120000

# Or reference a named script from .archon/scripts/ or ~/.archon/scripts/
- id: analyze
  script: analyze-metrics   # loads .archon/scripts/analyze-metrics.py
  runtime: uv
  deps: ["pandas>=2.0"]     # Optional, uv only — 'uv run --with <dep>'

Loop node — iterates AI prompt until completion. Declare at least one of until / until_bash; drop until when the condition is deterministic, so no prose is matched at all:

- id: implement
  loop:
    prompt: "Implement next story. When done: <promise>COMPLETE</promise>"
    until: COMPLETE               # Prose signal
    max_iterations: 10
    fresh_context: true
    until_bash: "bun run test"    # Exit 0 = done
    # until_field: done           # Or: a declared boolean in this node's output_format
    # At least ONE of until / until_bash / until_field

Loop group node — repeats a multi-node sub-DAG body per iteration (implement → test → review as one repeated cycle):

- id: fix-cycle
  loop_group:
    nodes:
      - id: implement
        prompt: "Implement the next fix. Last review: $LOOP_PREV.review.output"
      - id: test
        bash: "bun run test 2>&1 || true"
        depends_on: [implement]
      - id: review
        prompt: "Review diff + tests: $test.output. All good? <promise>SHIP</promise>"
        depends_on: [test]
    until: SHIP
    max_iterations: 6

Approval node — pauses the workflow for human review. Requires interactive: true at the workflow level for Web UI delivery:

interactive: true   # workflow level — required for web UI

nodes:
  - id: review-gate
    approval:
      message: "Review the plan above before proceeding."
      capture_response: true      # Optional: user's comment → $review-gate.output
      on_reject:                  # Optional: AI rework on rejection instead of cancel
        prompt: "Revise based on feedback: $REJECTION_REASON"
        max_attempts: 3           # Range 1-10, default 3
    depends_on: [plan]

Cancel node — terminates the workflow with a reason. Typically gated with when::

- id: stop-if-unsafe
  cancel: "Refusing to proceed: input flagged UNSAFE."
  depends_on: [classify]
  when: "$classify.output != 'SAFE'"
