document-mcp: Command for Claude Code

.claude/commands/0-context.md

0-context is a command for Claude Code from clchinkc/document-mcp. It costs 0 tokens per session (35 once invoked), scanned A, original, MIT.

A command that examines a codebase's file structure and how its parts relate, then records that information in CLAUDE.md. It first reads CLAUDE.md and README.md to understand the project.

In plain words
What is it for?
Use it to document repository structure, record relationships between files, and prepare CLAUDE.md before asking an agent to make code changes.
Why use it?
It creates written project context for future coding-agent sessions, reducing repeated exploration of the repository. CLAUDE.md is a file that gives an agent instructions and background for a codebase.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md.

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

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

0-context 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.

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.
