proofloop: Instructions file for Claude Code

CLAUDE.md

proofloop CLAUDE.md is an instructions file for Claude Code from exiw-ai/proofloop. It costs 551 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for Proofloop, an AI agent orchestrator: a tool that runs agents until defined completion conditions are met, then can pause and resume them. It supports Claude Code, OpenCode, and Codex through a layered Python application.

In plain words
What is it for?
Use them when developing Proofloop, running its tests and checks, adding or changing agent providers, and deciding which of its architectural layers should contain new code.
Why use it?
They give contributors a quick way to follow the project’s testing, formatting, typing, asynchronous-code, logging, and architecture rules. This keeps changes consistent across the command-line, business-logic, application, and infrastructure layers.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions Codex.

This is exiw-ai/proofloop's own configuration. It tells Claude Code how to work on proofloop 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 proofloop 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

proofloop CLAUDE.md 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.

Project Overview

Proofloop is an AI agent orchestrator - agents that run until done. Define conditions, go to sleep, wake up to results. Supports multiple providers: Claude Code, OpenCode, and Codex.

Key technologies: Python 3.12+, Typer (CLI), Pydantic, asyncio, Claude Code SDK, OpenCode, Codex

Code Style

  • Python 3.12+ with type hints required
  • Async/await for I/O operations
  • Use loguru for logging
  • Follow existing patterns in the codebase

Comments Policy

  • Avoid comments that restate the code
  • Docstrings only for public interfaces and non-obvious logic
  • Goal: self-documenting code

Architecture

The project follows layered architecture:

src/
├── cli/            # Command-line interface
├── domain/         # Business logic, entities, value objects
├── application/    # Use cases, orchestration
└── infrastructure/ # External adapters (Claude SDK, Git, MCP)

Rules:

  • Domain layer has no external dependencies
  • Infrastructure implements interfaces defined in domain
  • Keep business logic in domain, not in adapters

Guidelines

Do

  • Follow existing project structure and patterns
  • Keep changes minimal and focused
  • Add tests for functional changes
  • Run make check before committing

Don't

  • Commit secrets or API keys
  • Break existing tests
  • Add unnecessary defensive code for impossible cases
  • Invent custom implementations when a library exists

Dependencies

Core libraries used in the project:

  • Validation: pydantic
  • Retry logic: tenacity
  • Logging: loguru
  • HTTP: httpx

When Done

A change is complete when:

  • All checks pass (make check)
  • New behavior is covered by tests
  • Working tree is clean

System Contract

Key guarantees that must be preserved when modifying the core pipeline:

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.
