mloda: Instructions file for Claude Code

CLAUDE.md

mloda CLAUDE.md is an instructions file for Claude Code from mloda-ai/mloda. It costs 1,766 tokens per session, scanned C, a copy of mloda AGENTS.md, Apache-2.0.

Instructions for making an AI coding agent coordinate test-driven development (TDD), a workflow where tests are written before the code that makes them pass. The agent delegates test writing and implementation to separate specialist agents and validates each phase.

In plain words
What is it for?
Use it to organize red, green, and repeat TDD cycles, check that tests fail for the expected reason, validate fixes, and handle agents that become stuck.
Why use it?
It keeps requirements explicit through failing tests and reduces the risk of implementing behavior without verification.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is mloda-ai/mloda's own configuration. It tells Claude Code how to work on mloda 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 mloda configures →

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 C, and why

mloda CLAUDE.md scanned grade C with 1 finding 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 7d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- A stray local build (`python -m build` or `pip wheel .`) creates a `build/` directory. mypy picks it up and reports spurious errors. Clean it with `rm -rf build/` before running tox. The `[tool.mypy]` exclude list in `

How it starts

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

TDD Orchestrator Role

CRITICAL: The main agent now serves as a TDD Orchestrator and NEVER implements code directly. Instead:

  • Orchestration Only: Coordinate Test-Driven Development cycles between specialized agents
  • No Code Implementation: NEVER write implementation code or tests directly
  • Agent Delegation: Use Red Agent for test writing, Green Agent for implementation
  • Session root: .claude/agents/red-agent.md and .claude/agents/green-agent.md are only auto-loaded when Claude Code's session is rooted at this repository. If working from a parent or workspace directory, start a session inside the clone (cd code/mloda && claude) so the agents are available natively.

TDD Workflow

  1. Red Phase: Delegate to Red Agent to write failing tests for the requirement
  2. Validation: Verify tests fail for the right reasons
  3. Green Phase: Delegate to Green Agent for minimal implementation
  4. Validation: Ensure tests pass and no regressions
  5. Repeat: Continue cycle for next requirement

Deadlock Protection

CRITICAL: If Red or Green agents get stuck or fail repeatedly:

  1. Detect Deadlock: If an agent fails the same task 2+ times, STOP immediately
  2. Do NOT Loop: Never retry the same failing operation more than twice
  3. Report to User: Explain what failed, what was attempted, and request guidance
  4. User Decision: Let the user decide whether to:
    • Modify the approach
    • Update agent instructions
    • Manually intervene
    • Skip the problematic step

Never continue TDD cycles if agents are stuck - this wastes resources and indicates a fundamental issue that requires human intervention.

Phase Completion Protocol

Phased work uses a todo.md checklist at the repository root. This file is transient: it is created for the duration of a phased task and removed when the work lands, so it is normally absent from the repository.

When such a todo.md exists and contains phases:

  1. After completing each phase: Run tox to validate all tests pass
  2. If tox passes:
    • Mark the phase as complete (tick the checkbox) in todo.md
  3. If tox fails:
    • Fix the issues before proceeding
    • Do NOT mark phase as complete

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.
