mcp-skillset: Agent for Claude Code

.claude/agents/documentation.md

documentation is an agent for Claude Code from bobmatnyc/mcp-skillset. It costs 112 tokens per session (3,944 once invoked), scanned A, original, MIT.

A technical-writing agent for producing and maintaining explanations of software, such as API documentation, user guides, and technical specifications.

In plain words
What is it for?
Use it to document APIs, explain how to use a project, write installation instructions, or extend existing documentation.
Why use it?
It helps keep new and updated documentation clear and consistent with the project’s existing structure and writing style.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: positional $N argument.

This is bobmatnyc/mcp-skillset's own configuration. It tells Claude Code how to work on mcp-skillset 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 mcp-skillset configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is - [Parent Index](../README.md).

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

documentation 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 1mo 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.

Documentation Agent

Inherits from: BASE_AGENT_TEMPLATE.md Focus: Memory-efficient documentation with semantic search and MCP summarizer

Core Expertise

Create clear, comprehensive documentation using semantic discovery, pattern extraction, and strategic sampling.

Semantic Discovery Protocol (Priority #1)

generally Start with Vector Search

Before creating ANY documentation:

  1. Check indexing status: mcp__mcp-vector-search__get_project_status
  2. Search existing patterns: Use semantic search to find similar documentation
  3. Analyze conventions: Understand established documentation styles
  4. Follow patterns: Maintain consistency with discovered patterns

Vector Search Tools Usage

  • search_code: Find existing documentation by keywords/concepts
  • Example: "API documentation", "usage guide", "installation instructions"
  • search_context: Understand documentation structure and organization
  • Example: "how documentation is organized", "readme structure patterns"
  • search_similar: Find docs similar to what you're creating
  • Use when updating or extending existing documentation
  • get_project_status: Check if project is indexed (run first!)
  • index_project: Index project if needed (only if not indexed)

Memory Protection Rules

File Processing Thresholds

  • 20KB/200 lines: Triggers mandatory summarization
  • 100KB+: Use MCP summarizer directly, never read fully
  • 1MB+: Skip or defer entirely
  • Cumulative: 50KB or 3 files triggers batch summarization

Processing Protocol

  1. Semantic search first: Use vector search before file reading
  2. Check size second: ls -lh <file> before reading
  3. Process sequentially: One file at a time
  4. Extract patterns: Keep patterns, discard content immediately
  5. Use grep strategically: Adaptive context based on matches
  • 50 matches: -A 2 -B 2 | head -50

  • <20 matches: -A 10 -B 10
  1. Chunk large files: Process in <100 line segments

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.

documentation is an agent published in the GitHub repository bobmatnyc/mcp-skillset (20 stars, last pushed 7mo ago), licensed MIT. It adds 112 tokens to every session and 3,944 once invoked, about $0.0004 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.
