devflow

agents

Pi-specific agent tooling extracted from my dotfiles repo. Still need to port more of the old claude stuff.

Contents

• pi/extensions/ — package-shipped Pi extensions grouped into tools/, ui/, messaging/, cli/, and system-prompt/
• .pi/extensions/ — project-local Pi extensions for this repository only
• pi/agents/ — bundled subagents used by the subagent extension
• plugins/ — reusable prompt/skill plugins grouped by domain (devflow/, writing/, coding/, harness/)
• pi/themes/ — Pi themes

Note on Cache Invalidation: Changing prompt-layer context mid-session, or changing the model/provider, can drop provider prompt-cache reuse. Treat dynamic context injection as a cost/latency tradeoff; keep injected context bounded and stable when possible.

Install as a Pi package

From a local checkout:

pi install /absolute/path/to/agents

From git later:

pi install git:github.com/<you>/agents

Pi loads the package's extensions from pi/extensions/, plugin prompts and skills from plugins/*/, themes from pi/themes/, through package.json#pi. It also auto-loads this checkout's project-local extensions from .pi/extensions/ when Pi runs inside this repository. The bundled agents are discovered by the subagent extension from pi/agents/, so they travel with the package too. Project-specific agents still load from the nearest .pi/agents/ directory when you run Pi inside another repo.

This package ships a system-prompt extension that:

• replaces Pi's generated system prompt with a package-owned structure
• renders tool metadata tool-by-tool, including subagent inventory under the subagent tool
• injects global/project agent.njk rules

It also ships a project-structure messaging extension that sends a bounded project tree as model-visible custom message context.

This repository additionally keeps a project-local .pi/extensions/pi-internals/ tool that agents can call on demand to print Pi runtime/source/settings/enabled-extension paths. It is intentionally local to this checkout rather than shipped as part of the package.

See pi/extensions/system-prompt/README.md for prompt-layer extension details and .pi/extensions/pi-internals/README.md for project-local Pi internals discovery.

Bundled agents

• pi/agents/scout.md — fast codebase recon and architecture mapping
• pi/agents/fixer.md — validation repair and scoped mechanical completion agent
• pi/agents/hack.md — shell-first investigation and automation agent
• pi/agents/review.md — faster/cheaper single-agent code review for spot checks
• pi/agents/deep-review/ — multi-role review for a full feature, PR, or session workload; pass commits/diff, PRD/spec/task files, relevant paths, intent, risks, validation results, and any upfront exploration notes so each reviewer starts with shared hot context
• pi/agents/council/ — multi-role ideation panel for non-trivial decisions where the main agent wants another opinion before reporting back; includes skeptic, evidence scout, simplifier, and scope guard; pass proposed direction, intended outcome, problem, tradeoff/decision, relevant files/specs/code paths, constraints, risks, rejected options, and desired help

Included plugins

• plugins/devflow/ — AFK workflow prompts/skill plus HITL, shrug, and grill-me prompts
• plugins/writing/ — skill authoring, spec authoring, and Mermaid writing skills
• plugins/coding/ — git, robustness, writing-tests skills plus coding prompts
• plugins/harness/ — harness/session affordances such as Pi session introspection and rich responses

Development

The Vitest suite includes both unit/snapshot tests and Pi runtime integration tests backed by @gaodes/pi-test-harness.

pnpm install
pnpm format
pnpm lint
pnpm typecheck
pnpm check

Running pi from this repo works for local testing because .pi/settings.json points Pi at the package root.
