systematic: Skill for Claude Code

.agents/skills/generating-project-docs/SKILL.md

generating-project-docs is a skill for Claude Code from marcusrbrown/systematic. It costs 35 tokens per session (2,391 once invoked), scanned A, original, MIT.

A documentation workflow for creating or updating project files such as README.md, ARCHITECTURE.md, and STRUCTURE.md from the current codebase.

In plain words
What is it for?
Use it to refresh a project README, document system architecture or folder structure, or update one named documentation section.
Why use it?
It reduces stale or generic documentation by requiring descriptions to match files and commands that actually exist.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: mentions subagents; installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is marcusrbrown/systematic's own configuration. It tells Claude Code how to work on systematic itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything systematic configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bun src/cli.ts list skills 2>/dev/null # skill count + names.

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

generating-project-docs 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 2mo 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.

The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Generating Project Documentation

Overview

This plugin's documentation describes a live system whose surface (skills, agents, config schema, CLI) keeps changing. Generated docs go stale fast.

Core principle: Derive every fact from the live repository. Preserve the existing document's evolved structure. Never regress to a generic template.

If you cannot point at a file or command that justifies a sentence, do not write it.

When to Use

  • Refreshing README.md after new skills, agents, or features land
  • Fixing documentation drift (counts, structure, CLI output, runtime claims)
  • Updating ARCHITECTURE.md or STRUCTURE.md when the codebase layout changes
  • Adding or refreshing a scoped section (e.g. only the "Quick Install" block)

When NOT to Use

  • Writing planning docs (docs/plans/, docs/brainstorms/) — those follow their own templates
  • Authoring skill or agent files — those have their own format rules

Arguments

$ARGUMENTS
  • Empty or readme — Update README.md (default)
  • architecture — Update ARCHITECTURE.md
  • structure — Update STRUCTURE.md
  • all — Update all three docs
  • <section-name> — Update only that named section within the target doc (e.g. skills, agents, cli)

For scoped updates: read the current document, locate the section by heading, replace only that section's content. Preserve surrounding structure exactly.

Pre-Generation Inventory

Before writing anything, gather these from the live repo:

package.json name, version, description, scripts, repository URL
bun src/cli.ts list skills 2>/dev/null exact skill count and names
bun src/cli.ts list agents 2>/dev/null exact agent count, names, categories
bun src/cli.ts list commands 2>/dev/null command inventory
find skills -name SKILL.md -exec head -6 {} \; -exec echo --- \; skill frontmatter (name, description)

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.
