Opencode

Open-source coding agent that runs from the CLI, can run headlessly via opencode run, supports named agents, and can connect to tools through MCP. Loop engineering primitives publish to plain files: AGENTS.md, STATE.md, and skills/ folders in the AgentSkills format.

Example	Pattern
daily-triage.md	Daily Triage (L1 report → L2 assisted)
constraints.md	Constraints (binding rules loaded before every loop run)
ci-sweeper.md	CI Sweeper (cron/systemd + opencode run for short cadences)
pr-babysitter.md	PR Babysitter (long-running PR shepherd with worktree isolation)
Constraints Example – Minimal loop-triage skill with recommended guardrails.

Starter kit: ../../starters/minimal-loop-opencode/ — clone-and-run scaffold for L1 daily triage.
