Turn Cursor, Claude Code, the OpenAI API, or the Codex CLI into an orchestrator that routes every task to the cheapest model that can handle it, runs workers as independent processes, and stores their output as typed SQLite artifacts so follow-ups cost zero tokens.

The 35.1% figure is a 6-task mixed-workload dry-run where the router correctly kept the frontier model on the 2 hard tasks — full method in docs/CLAIMS.md.

pipx install puppetmaster-ai # or: pip install puppetmaster-ai
puppetmaster setup # doctor + models init + MCP installers + agent rules, idempotentThat's the whole install. setup runs every step idempotently, skips any tool that isn't present, and prints what it did. Restart Cursor (or open a fresh Codex / Claude session) and the agent sees 32+ puppetmaster_* tools plus a rule nudging it to reach for them on multi-file work.
To run benchmarks or hack on it, clone instead — see Contributing. (pipx keeps the CLI in its own isolated environment, which is the recommended way to install a command-line app.)

Puppetmaster isn't trying to beat native IDE subagents at every tiny task. It's for the work that gets messy: long repo investigations, conflicting hypotheses, repeated handoffs, flaky memory, and code changes that need evidence, replay, and approval gates. The rationale and failure modes it fixes are in docs/WHY.md.
How it's different: LangGraph, CrewAI, and the Claude Agent SDK are libraries you write code against to build an agent. Puppetmaster sits one layer up — it orchestrates the agent CLIs you already pay for (Cursor, Claude Code, Codex, OpenAI), routes each task to the cheapest sufficient model, keeps the spend inside your subscription, and self-heals when a provider is down. Full side-by-side + "pick X instead if…" in docs/COMPARISON.md.
The whole story in one command — local + shell adapters, nothing to configure:
./scripts/demo.sh # the 60-second tour (clean machine, no keys)
python -m puppetmaster dashboard # live, zero-dependency web board for any jobIt routes a task mix by cost, fans out a 6-role swarm as independent processes, reads the stitched summary, then proves follow-up reads cost $0.00. Script + GIF source: scripts/.
Every number is reproducible from a script in bench/. Full detail + caveats: docs/CLAIMS.md.
- Cost is fixed on two axes. New work auto-routes to the cheapest sufficient model (35% cheaper on a fixture; 98.8% cheaper in a live OpenAI A/B). Follow-ups are SQLite reads, not new agent runs (40 queries, $0.00, 0.5 ms each).
- Workers don't share a transcript. They lease tasks and emit typed artifacts (payload +
evidence+confidence+sha256); the stitcher reads JSON, not stdout. Inspect withpuppetmaster artifacts <job_id>. - Graphing is CodeGraph's win, wired in cleanly. Workers auto-inject task-relevant graph context before the model call; fall back to grep/read without it. (docs/CODEGRAPH.md)
- A dead provider doesn't kill the swarm (v0.9.0+). Billing/quota/auth/missing-CLI failures are marked
FAILEDand auto-rerouted to the next funded adapter, preferring plan-billed models. Validated live; surfaced loudly in the summary's Alerts section.
After install, try one of these inside Cursor Agent or Codex:
Use Puppetmaster to run doctor in this repo and summarize what is missing.
Use Puppetmaster to start a cursor swarm for this repo and return the job id immediately.
Problem: users get logged out after refresh and token-refresh tests are flaky.
Constraints: keep the patch focused, preserve public API behavior, run relevant tests.
Do review/plan first. Poll status/logs by job id. Do not edit until you summarize findings and ask for approval.
Or from the shell:
puppetmaster doctor
puppetmaster route "Security audit every endpoint" --role audit # dry-run routing decision
puppetmaster cursor "Review this repo for release blockers" --review --dry-run
puppetmaster claude "Implement the approved change and run focused tests" --permission-mode acceptEdits

Daily-driver beta. Real runtime contract, automated tests, SQLite default backend, fail-closed jobs, live Cursor Agent MCP, installable Cursor extension, validated full-edit adapters. Credible for supervised local engineering; not yet a hosted multi-user service. Full feature matrix: docs/FEATURES.md.
Pip name: PyPI lists this as puppetmaster-ai because PEP-503 normalization collides puppetmaster with an abandoned 2019 puppet-master. The import name, CLI, repo, and brand stay puppetmaster. (tracking)
