Run Codex CLI, Claude Code, OpenCode, or Pi Coding Agent via background process for programmatic control.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Coding Agent (bash-first) Use **bash** (with optional background mode) for all coding agent work. Simple and effective. ## ⚠️ PTY Mode Required! Coding agents (Codex, Claude Code, Pi) are **interactive terminal applications** that need a pseudo-terminal (PTY) to work correctly. Without PTY, you'll get broken output, missing colors, or the agent may hang. **Always use `pty:true`** when running coding agents: ```bash # ✅ Correct - with PTY bash pty:true command:"codex exec 'Your prompt'" # ❌ Wrong - no PTY, agent may break bash command:"codex exec 'Your prompt'" ``` ### Bash Tool Parameters | Parameter | Type | Description | |-----------|------|-------------| | `command` | string | The shell command to run | | `pty` | boolean | **Use for coding agents!** Allocates a pseudo-terminal for interactive CLIs | | `workdir` | string | Working directory (agent sees only this folder's context) | | `background` | boolean | Run in background, returns sessionId for monitoring | | `timeout` | number | Timeout in seconds (kills process on expiry) | | `elevated` | boolean | Run on host instead of sandbox (if allowed) | ### Process Tool Actions (for background sessions) …

How to install
mdr add metaspartan/cybara/coding-agent@sha256:3cff4eae4e4b692cThe line at the top of this page pins the label git:20260218.a87179d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
