Sessions have been agent-scoped since v34, but the schema kept four
dead task-scoped columns that every session code path had to pretend
were meaningful:
- tasks.active_session_id (mirrored agents.session_id)
- tasks.session_json (superseded by task_sessions.session_params_json)
- tasks.session_display_id (superseded by task_sessions.session_display_id)
- task_sessions.task_id (always empty-string on new rows)
v41 drops all four via SQLite table rebuild — the only safe path when
multiple columns need to go in one step and indexes / FK directions
need to be preserved. `PRAGMA foreign_keys = OFF` spans the swap
window so cascade-delete does not fire mid-rebuild. The migration is
idempotent and also backfills the optional task columns
(task_type / requires_user_review / retry_count / last_failure_at /
started_at / completed_at / cancelled_at / checkout_run_id /
execution_locked_at) before rebuilding so it works whether or not
`ensureOptionalColumns` has run yet on this install.
Along with the schema change, every code path that read or wrote
those columns has been rewired to the agent-scoped equivalents:
- task-sessions-crud.ts: deleted updateTaskSession,
getTaskSession, getActiveTaskSession, updateTasksActiveSessionForAgent;
added updateSessionParams(sessionId, ...) for the worker's
finalizer. ensureAgentSession and createNewSession no longer touch
task_id.
- database-base.ts: facade drops the now-unused pass-throughs.
- snapshot.ts / task-queries.ts / tasks-status.ts / entity-crud.ts:
SELECT projections no longer pull session_json / session_display_id
/ active_session_id from tasks.
- tasks-crud.ts (TaskRow) and shared/types/records-core.ts
(TaskRecord): sessionJson / sessionDisplayId fields removed.
- TaskSessionRecord: taskId field removed.
- turn-context.ts::resolveSession: no more
updateTasksActiveSessionForAgent mirror; sessionParams read directly
from the current session via getSessionById.
- run-finished-helpers.ts::finalizeRun: stamps sessionParams via
updateSessionParams on the agent's current session, resolved through
agents.session_id.
- session-management-service.ts: rotateSession stops calling
updateTasksActiveSessionForAgent.
Test suite updated to use the new session-id API. Existing tests used
`getActiveTaskSession(taskId)` and `createNewSession({ taskId, ...})`
as probes; they now use `getSessionById(sessionId)` and the taskId-less
createNewSession input.
Tests: 603/603 green. Typecheck clean. Migration tested on fresh DB
(runs v1→v41 cleanly) and idempotent re-apply (detects absent dead
columns, skips).
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
