medusa AGENTS.md

medusa AGENTS.md is an instructions file for Codex, OpenCode from Skowt/medusa. It costs 152 tokens per session, scanned A, original, MIT.

Project instructions for Medusa, a terminal user interface for running several coding agents in parallel. They describe its Go technology, entry points, tests, and release process.

In plain words
What is it for?
Use them when modifying Medusa, running its end-to-end or performance checks, validating terminal behavior, or preparing an explicitly requested release.
Why use it?
They give agents the project rules and validation steps needed to make safe changes without committing or pushing unexpectedly.

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

medusa AGENTS.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 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.

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.

What it actually says

AGENTS

  • Do not commit or push unless the user explicitly requests it.
  • Tech stack: Go TUI built on Bubble Tea v2 (Charm); styling via Lip Gloss; terminal parsing via internal/vterm.
  • Entry points: cmd/medusa (app) and cmd/medusa-harness (headless render/perf).
  • E2E: PTY-driven tests live in internal/e2e and exercise the real binary.
  • Work autonomously: validate changes with tests and use the harness/emulator to verify UI behavior without a human.
  • Release: use make release VERSION=vX.Y.Z (runs tests + harness, tags, pushes). Tag push triggers GitHub Actions release.
Changes

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.
