pi-extensions (milanglacier)

Eight independently installable pi extensions in one monorepo: plan mode, dynamic subagent workflows, background tasks, per-session model switching.

extensions✓ Sep 22

Each extension installs on its own: pi install npm:<package> or pi install github:milanglacier/<repo> — the README links every extension's repository from the monorepo index

## TL;DR

A monorepo of eight independently installable pi extensions: /plan structured planning, /workflow JavaScript subagent orchestration, background tasks with a dashboard, a minimal permission layer, /session-model, /regenerate, automatic theme switching, and a Gemini BLOCK_NONE patch.

## Key points

• $Planning and orchestration: pi-plan-mode injects a planning prompt and exposes planning tools directly on the main conversation — no separate planner subagent — with planning state resumable across sessions; pi-dynamic-workflow has the model author a small JavaScript orchestration script on the fly and fan it out into isolated pi subagent subprocesses via /workflow, where failed subagents yield null instead of rejecting the batch.
• $Background tasks: pi-background-tasks adds the bg_task and bg_status tools, a /bg slash command, and a multi-pane dashboard on Ctrl+Shift+B for spawning, watching, and stopping tracked background processes, with persistent log files and follow-up wakeups when a watched task emits output or exits.
• $Permission policies: pi-minimal-permission-system guards the built-in read, edit, write, and bash tools with global and project-local policies, including read-only access to sensitive paths; MCP and extension tools are intentionally out of scope.
• $Session-scoped conveniences: pi-session-model switches the active model and optional thinking level for the current session only via /session-model, touching no global defaults; pi-regenerate-last-response adds /regenerate (shorthand /reg), branching back to the preceding user message and re-triggering the agent.
• $Environment and provider tweaks: pi-theme-switcher flips the terminal theme between dark and light from environment variables (PI_AGENT_THEME, THEME_MODE) or time of day, with a configurable night window; pi-gemini-patch forces BLOCK_NONE across Gemini safety categories by merging settings into the request config object (OpenRouter Gemini models excluded).
• $Monorepo layout: every top-level directory is a git submodule pointing at its own repository, so each extension typechecks and tests independently and installs one at a time.
