BatonHandoffs your agent can put down and pick back up.

Portable, validated, local-first context handoffs for coding agents. Capture a checkpoint mid-task, validate it against the policy you chose, and resume later — in the same harness or a different one.

What is Baton?

🏏

Capturable checkpoints

One command captures work-in-progress, decisions, evidence, and next steps into a versioned, on-disk handoff document.

✅

Validation before readiness

Policy-driven validation gates — no handoff becomes "ready" until completeness, lineage, and consistency checks pass.

🔒

Local-first by construction

Everything lives in .baton/ in your project. No cloud, no telemetry by default, secrets redacted at capture time.

🔌

Harness-agnostic

A generic adapter plus an MCP server and a Hermes context-engine plugin. Same schema, same behavior, everywhere.

📜

Schema-driven

JSON Schemas are generated artifacts from a single Zod source of truth, validated against real fixtures on every test run.

🧭

Resumable anywhere

The ≤1,200-token resume brief renders to Markdown or JSON and is designed to be pasted into any agent's context.
