doc

doc is a command for coding agents from MadAppGang/magus. It costs 28 tokens per session (3,286 once invoked), scanned A, a copy of doc, MIT.

A command for creating, reviewing, repairing, or checking project documentation such as READMEs, API references, tutorials, and changelogs.

In plain words
What is it for?
Generating and validating the written guides and reference material that explain a project.
Why use it?
It helps find unclear, incomplete, or outdated documentation before it causes confusion.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Part of the dev plugin — 41 skills, 13 commands, 13 agents shipped together

Install

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.

agentmods
npx agentmods add commands/madappgang/magus/doc
Clone the repo
git clone --depth 1 https://github.com/MadAppGang/magus

Or install dev, the plugin that ships this one along with the rest of its 41 skills, 13 commands, 13 agents.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

doc 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 yesterday.

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.

Origin

This is a copy

86% identical to doc — 69 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 398 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<user_request> $ARGUMENTS </user_request>

  Before starting, create todo list based on action:
  - GENERATE: Detect type, gather context, generate, validate
  - ANALYZE: Read docs, score quality, detect anti-patterns, report
  - FIX: Analyze issues, apply fixes, validate improvements
  - VALIDATE: Check against best practices, generate report

  **Tasks Ownership Rules:**
  - You (the orchestrator) OWN the Tasks list exclusively
  - The dev:docs sub-agent MUST NOT modify Tasks
  - Sub-agents report progress via their return messages only
  - Use 1-based phase numbering (Phase 1, 2, 3...)
  - Maintain exactly ONE todo in_progress at any time
</todowrite_requirement>

<orchestrator_role>
  **You are an ORCHESTRATOR, not IMPLEMENTER.**

  **You MUST:**
  - Use Agent tool to delegate ALL documentation work to agents
  - Enforce quality gates between phases
  - Use file-based communication for large outputs

  **You MUST NOT:**
  - Write or edit documentation files directly
  - Skip quality validation
</orchestrator_role>

<approval_gates>
  **User Approval Required for Destructive Changes:**

  Before FIX mode applies changes, you MUST:
  1. Show preview of changes to user
  2. Use AskUserQuestion: "Ready to apply {fix_count} fixes to {file_count} files.
     Preview: {summary}. Proceed? (yes/no)"
  3. Wait for explicit confirmation before running dev:docs in fix mode

  Before GENERATE overwrites existing files:
  1. Check if target file exists
  2. If exists, use AskUserQuestion: "File {path} already exists. Overwrite? (yes/no/backup)"
  3. If "backup", save existing file before generating new one
</approval_gates>

<delegation_rules>
  **Agent Delegation:**
  - README generation: dev:docs (mode=write)
  - API documentation: dev:docs (mode=write)
  - Tutorial creation: dev:docs (mode=write)
  - Changelog generation: dev:docs (mode=write)
  - Quality analysis: dev:docs (mode=analyze)
  - Anti-pattern detection: dev:docs (mode=analyze)
  - Issue fixing: dev:docs (mode=fix)
  - Voice/style transformation: dev:docs (mode=fix)
</delegation_rules>

</critical_constraints>

<action_detection> Analyze $ARGUMENTS to determine action:

**GENERATE** (triggers: "create", "generate", "write", "document", "add docs"):
- Generate new documentation
- Identify doc type: README | API | Tutorial | Changelog | Error | ADR

**ANALYZE** (triggers: "analyze", "check", "score", "review", "audit"):
- Analyze existing documentation quality
- Score against 52-point checklist
- Detect anti-patterns

**FIX** (triggers: "fix", "improve", "update", "refactor"):
- Fix identified issues
- Apply transformations (passive -> active voice)
- Add missing sections

**VALIDATE** (triggers: "validate", "verify", "test"):
- Check against best practices
- Verify examples work
- Check links

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.
