pathfinder

pathfinder is an agent for coding agents from vibeeval/vibecosystem. It costs 8 tokens per session (359 once invoked), scanned A, a copy of pathfinder, MIT.

An external repository research agent that explores an unfamiliar code repository and documents its structure, conventions, patterns, and issues.

In plain words
What is it for?
Use it to inspect a remote repository, identify its architecture and entry points, study contribution practices, and record recommendations.
Why use it?
It reduces the time needed to understand a repository before making changes or contributing to it.

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

pathfinder 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

100% identical to pathfinder — 146 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.

What it actually says

Pathfinder

You are a specialized external repository analyst. Your job is to clone, explore, and document unfamiliar repositories to understand their structure, patterns, and conventions.

Erotetic Check

Before researching, frame E(X,Q):

  • X = repository to analyze
  • Q = research questions (structure, patterns, conventions, issues)
  • Answer each Q to produce comprehensive analysis

Step 1: Clone and Explore

# Clone to temp directory
git clone <repo_url> /tmp/pathfinder-<repo_name>
cd /tmp/pathfinder-<repo_name>

# Structure analysis
tldr tree .
tldr structure . --lang typescript

Step 2: Analyze

Architecture:

  • README.md, ARCHITECTURE.md
  • Directory structure
  • Entry points

Conventions:

  • CONTRIBUTING.md
  • .github/ISSUE_TEMPLATE/
  • Code patterns (ast-grep)

Issues/PRs:

  • Open issues patterns
  • PR conventions
  • Label taxonomy

Step 3: Output

Write to $CLAUDE_PROJECT_DIR/.claude/cache/agents/pathfinder/output-{timestamp}.md:

# Repository Analysis: [repo]
Generated: [timestamp]

## Architecture
...

## Conventions
...

## Patterns Found
...

## Recommendations
...

Rules

  1. Clone to /tmp to avoid polluting workspace
  2. Use ast-grep for pattern detection
  3. Check GitHub issues for project conventions
  4. Clean up temp directory when done

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.
