Drawer Statusline

My drawers of independently installable plugins for two agent harnesses — opencode and pi.

A "drawer" is a Bun-workspace monorepo: each plugin is published and installed on its own, but plugins sit on shared foundations and are grouped by the harness they target — packages/opencode/* and packages/pi/*.

opencode plugins

The opencode plugins share @drawers/core, a private package providing the common engine — SDK client adaptation, the completion gate over opencode's session.idle / session.error stream, the per-parent notification queue, and toast notifiers. The plugins are thin entries; the durable machinery lives in core.

Package	What it gives you	Docs
opencode-drawer-agents	Fire-and-forget background agents — launch a task in a child session and pull its output later, without blocking the main loop. Tools: bg_task, bg_output, bg_cancel, bg_list.	README
opencode-drawer-workflows	Deterministic multi-agent orchestration — author a workflow as JavaScript that fans out subagents, runs barriers and conditionals, and returns schema-conforming results. A port of Claude Code's Workflows feature, with the six named orchestration patterns, per-agent git-worktree isolation, a deep-research built-in, and save-a-run-as-workflow. Tools: workflow, workflow_status, workflow_stop, workflow_save_run (plus a global structured_output tool), and a native /workflows TUI viewer.	README
opencode-drawer-cadence	Session-level re-prompting that mirrors Claude Code's /loop and /goal: drive the current session on a fixed interval, or until the model declares a goal met. Tools: loop, goal, cadence_stop, cadence_list.	README
opencode-drawer-statusline	A compact prompt status line — directory, worktree, branch, session status, and opencode version under every prompt.	README

Add the plugins you want to your opencode.json:

{
  "plugin": [
    "opencode-drawer-agents",
    "opencode-drawer-workflows",
    "opencode-drawer-cadence",
    "opencode-drawer-statusline"
  ]
}

Install any subset — they are independent. See each package README for tool parameters and usage.

pi plugins

The pi port of the same set, targeting pi, whose plugin model is called extensions (@earendil-works/pi-coding-agent). They share @drawers/pi-core — the pi-native engine: a SessionRunner that spawns one pi --mode rpc child per task and fuses agent_end + process-exit into an exactly-once terminal (replacing opencode's session.idle completion gate), plus the harness-agnostic persistence / notification-queue / concurrency layers under the pi-drawers data namespace.

Package	What it gives you	Source
pi-drawer-agents	Fire-and-forget background agents — launch a task in a child pi session and pull its output later. Tools: bg_task, bg_output, bg_cancel, bg_list.	src
pi-drawer-workflows	Deterministic multi-agent orchestration — author a workflow as JavaScript that fans out child pi sessions, runs barriers and conditionals, and returns schema-conforming results; per-agent git-worktree isolation, a deep-research built-in, save-a-run-as-workflow. Tools: workflow, workflow_status, workflow_stop, workflow_save (plus a global structured_output tool), and a /workflows TUI viewer.	src
pi-drawer-cadence	Session-level re-prompting: loop (interval-driven) and goal (idle-driven, stops on a GOAL_COMPLETE sentinel). Tools: loop, goal, cadence_stop, cadence_list.	src
pi-drawer-statusline	A compact status line in pi's footer — directory, worktree, branch, session status, and pi version.	src

pi loads extensions as TypeScript via jiti (no build step). Install a package with pi install <source> (a local path references it in place; npm/git sources are fetched) or add it to the packages array in pi's settings.json:

pi install npm:pi-drawer-agents       # once published
pi install ./packages/pi/workflows    # local, pulled from this repo

Building plugins

Two Claude Code skills in this repo do the heavy lifting when adding a drawer:

Skill	For	SDK
opencode-plugin-dev	opencode plugins	@opencode-ai/plugin
pi-plugin-dev	pi extensions	@earendil-works/pi-coding-agent

Development

bun install          # install workspace dependencies (glob: packages/*/*)
bun test             # run the test suite (opencode + pi packages)
bun run typecheck    # tsc --noEmit across every package
bun run lint         # biome check .

Smoke harnesses exercise the plugins end to end against the real harness. The opencode smokes need an opencode binary on PATH; the pi smokes spawn a real pi --mode rpc child. All hit a live model — they cost tokens and take real wall-clock time, so they are gated out of bun test:

bun run smoke:agents       # opencode background-agents
bun run smoke:workflows    # opencode workflows
bun run smoke              # opencode core harness
bun run smoke:pi-runner    # pi @drawers/pi-core SessionRunner (real pi child)
bun run smoke:pi-agents    # pi background-agents (bg_task -> bg_output)
bun run smoke:pi-workflows # pi workflows (one-agent workflow -> result)
