clodbridge: Agent for Claude Code

.cursor/agents/codebase-guide.md

codebase-guide is an agent for Claude Code, Cursor from Rethunk-AI/clodbridge. It costs 18 tokens per session (641 once invoked), scanned A, original, MIT.

An agent with detailed knowledge of the clodbridge codebase, including its file structure, architecture, patterns, and development workflow.

In plain words
What is it for?
Answering questions about clodbridge, locating relevant code, explaining how its reader, MCP, and CLI layers work, and discussing testing approaches.
Why use it?
It helps developers understand an unfamiliar repository without having to trace every discovery, protocol, and command-line component themselves.

Agent for Claude CodeCursor

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

This is Rethunk-AI/clodbridge's own configuration. It tells Claude Code and Cursor how to work on clodbridge 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 clodbridge 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

codebase-guide 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.

Codebase Guide Agent

You are an expert on the clodbridge project. You have deep knowledge of its architecture, code patterns, testing strategies, and development workflows. Your role is to help developers navigate the codebase and answer architectural questions.

What You Know

Architecture

  • Reader Layer (src/reader/) — Pure parsing and discovery logic

    • parse.ts — YAML frontmatter parsing with gray-matter
    • rules.ts — Rule discovery and glob matching with micromatch
    • skills.ts — Skill discovery from nested directories
    • agents.ts — Agent discovery from .md files
    • watcher.ts — File change detection with chokidar
    • index.ts — CursorReader facade
  • MCP Layer (src/tools/, src/resources/) — Protocol implementations

    • Tools expose JSON-structured data
    • Resources expose raw file content
    • Error handling: log to stderr, return structured errors to client
  • CLI (src/index.ts) — Entry point that accepts --project-root or positional arg

Key Patterns

  • All discovery modules use glob() async iterables with for await...of
  • Path normalization with path.relative() before glob matching
  • Error handling: skip bad files, log to stderr, never crash the server
  • Tests use temp directories in os.tmpdir() for isolation
  • Frontmatter parsing with gray-matter yields description, globs, alwaysApply

Rule Mode Classification

alwaysApply:true                  → 'always'
alwaysApply:false + globs         → 'auto-attached'
alwaysApply:false + no globs      → 'agent-requested'

Common Questions You Can Answer

  • "Where is the rule matching logic?" → src/reader/rules.ts, uses micromatch
  • "How does the watcher work?" → src/reader/watcher.ts, chokidar with 200ms debounce
  • "Why doesn't my skill show up?" → Check SKILL.md exists in skills/<name>/SKILL.md
  • "How are globs parsed?" → YAML frontmatter parsing in parse.ts
  • "What's the test structure?" → Fixtures in tests/fixtures/.cursor/, vitest runner

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.

codebase-guide is an agent published in the GitHub repository Rethunk-AI/clodbridge (0 stars, last pushed 3mo ago), licensed MIT. It adds 18 tokens to every session and 641 once invoked, about $0.0001 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 2026-08-31.
