mloda: Instructions file for Codex

AGENTS.md

mloda AGENTS.md is an instructions file for Codex, OpenCode from mloda-ai/mloda. It costs 1,812 tokens per session, scanned C, original, Apache-2.0.

Repository instructions that make the main agent coordinate test-driven development, or TDD, where tests are written before the code they check. They define separate test-writing and implementation phases, plus rules for handling repeated failures.

In plain words
What is it for?
Use them to organize feature work into failing-test, implementation, and validation phases, while detecting deadlocks and confirming each phase is complete.
Why use it?
They give an agent team a fixed development process and prevent the main agent from bypassing the required testing workflow.

Instructions file for CodexOpenCode

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

This is mloda-ai/mloda's own configuration. It tells Codex and OpenCode 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 AGENTS.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 5d 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.
