pi's `transformContext` hook fired on every LLM call but returned the transcript unchanged, so a long-running agent paid per-token for its entire history on every turn. The README promised "sessions persist + auto-compact" but the main loop had no compaction wired in at all — only rotation at the long-cycle boundary. `context-compactor` closes that gap. A pure, provider-free function estimates tokens (~4 chars/token), short-circuits below a 120K threshold, and on overflow keeps the last 20 messages verbatim while collapsing older ones into a single "context summary" user turn. The summary preserves the original task and the first twelve assistant highlights so the agent has continuity without forwarding every historical turn. Compaction is non-destructive: the Agent's in-memory transcript and the SQLite session store still hold the full history, feeding UI timelines and audit. Only the LLM payload shrinks. Rotation remains the long-cycle boundary (separate commit) — compaction is what keeps each individual LLM call within budget.
AgentCompany
Run an AI company from your desktop.
What it does
Type a company name and a goal. A CEO agent boots, hires specialists, forms departments, and runs the business. You approve or steer from the desktop.
Local, SQLite-backed, no external services. Inspired by Paperclip.
26 providers, no CLI
The runtime links pi-mono directly.
OAuth (5): Claude Pro/Max · ChatGPT Plus/Pro (Codex) · GitHub Copilot · Gemini CLI · Antigravity
API key (18): Anthropic · OpenAI · Google · Mistral · Groq · Cerebras · xAI · OpenRouter · Vercel AI Gateway · ZAI · OpenCode · OpenCode Go · Hugging Face · Kimi · MiniMax · MiniMax CN · Fireworks · Fireworks Firepass
Cloud (3): Azure OpenAI · AWS Bedrock · Google Vertex AI
Credentials are SecretVault-encrypted in SQLite.
Two execution modes
- AI CEO — autonomous. Hiring, tasks, deliverables run without you.
- AI Co-Founder — pauses at
hire_agent/document_review/plan_review/strategy_reviewfor your decision.
Switch at Settings → Execution mode.
Features
Self-organizing teams
CEO builds the org chart from one goal.
Agent messaging
Threads and DMs between agents. Messages land in each recipient's transcript as pi AgentMessage turns.
Tasks
Goals break into tasks. Agents pick them up, report progress, escalate blockers.
Approvals
Hiring, deliverables, plan/scope/strategy reviews, budget overrides, production deploys pause for the board.
Documents
Plans, strategies, and specs in a shared center, linked to the tasks that produced them.
Launch in a minute
Name, mission, goal, provider, mode.
Quick Start
Download the latest release — macOS (Apple Silicon & Intel), Windows, Linux.
Build from source
# Node.js 22+, pnpm 10+
pnpm install
pnpm dev
First run
- Onboarding probes your shell PATH for
node(agents call the local HTTP API vianode -e). - Settings → Providers. Sign in or drop a key.
- Create a company: name, mission, goal, mode, workspace.
Verification
pnpm typecheck
pnpm lint
pnpm test:unit
pnpm test:integration
pnpm test:e2e
pnpm build:verify
Packaging
pnpm build # Package for current platform → /build/release
pnpm build:dir # Unpackaged directory
pnpm build:current # Current host platform
pnpm release:local # Signed release pipeline — see docs/release/local-r2.md
Targets: macOS .dmg, Windows .exe (NSIS), Linux .AppImage. Built with electron-builder. Local builds use ad-hoc signing (CSC_IDENTITY_AUTO_DISCOVERY=false). Defaults to --publish never.
