Bailey PossibLaw
Field guide · the walled courtyard for AI legal work

Build your own Firm.

Bailey is a whole firm of AI agents — intake, delegation, drafting, review, and the business around it — that runs behind gates, budgets, ethical walls, and hash-chained receipts. Not a chatbot. A firm, with controls — where every step is on the record and nothing leaves without a human.

What makes it a courtyard

The governance layer is the product.

Building a good agent is hard — and it's only the beginning. Before an agent can touch legal work, it needs walls, budgets, gates, and receipts around it. Bailey wraps every agent — whatever model is behind it — in the controls a law practice actually needs.

01

On the record from word one

Work is handed to a firm, not a chat window. Every request becomes a matter with an owner; every handoff between agents is a sub-matter you can open, read, and audit.

02

Spending, governed

Every agent runs under a hard budget cap it cannot exceed, with every token metered — per agent, per matter, per company. The spending stops before you get surprised.

03

Nothing leaves without a human

Outbound actions — a court filing, an e-signature, a document upload — stop at an egress gate and wait, hash-only, for a human to approve or reject. No exceptions, no override.

04

Don't trust it. Check it.

Every gated decision writes a hash-chained receipt you can verify offline with openssl — plus optional RFC 3161 timestamp anchoring. The spec is public; a standalone verifier ships in the repo.

05

Screened means screened

Ethical walls run as separate companies with separate gates and receipt chains. A screened matter says it is screened — denied is never dressed up as nonexistent.

06

Yours to extend

Create new agents with custom skills, connectors, and tools — shaped to your business and your practice of law. Swap the models underneath: cheaper where it's routine, stronger where it counts.

Open the gate

What's inside

A layer, not a fork: Bailey packages a complete legal operation on top of the open-source paperclip agent runtime — pinned, never modified. The governance pieces are standalone and portable.

180
agents in a real org chart — chief of staff, chief counsel, 34 practice & business leads, 140+ specialists
178
skills: playbooks, checklists, connectors — from NDA triage to conflicts screens to renewal tracking
28
legal practice areas plus the 6 business functions a firm actually runs on
400+
automated tests across the gate proxy, walls, trace store, and eval harness

We benchmarked our own thesis.
Here's what held, and why it matters.

Bailey began as a bet that atomic work, decomposed and reassembled by an orchestrated firm, would beat one strong model. On the affordable, non-frontier tiers we tested, it didn't clear that bar: on Harvey's public LAB benchmark — long-horizon graded tasks, scored by Harvey's own grader — orchestration showed a higher ceiling (every top-scoring run in the campaign was orchestrated) but an equal median. What did hold is the governance layer. The gates, budgets, walls, and receipts work identically no matter which model is underneath.

So that's how you use Bailey: keep building and keep testing. Improve the skills. Improve the tools. Swap in stronger models as they arrive, and re-run the harness — it ships in the repo, with all of our data, so your next result replaces ours.
