Blobfish Litigation Bench

Executable, long-horizon litigation environments for training and evaluating tool-using agents. 100 tasks, 104-113 verified tool-calling steps each (median 108), graded by deterministic state-diff — no LLM judge anywhere on the reward path.

Every task runs inside a stateful law-firm simulation exposed over MCP: nine litigation systems of record (matters, parties, claims, pleadings, motions, discovery_requests, depositions, exhibits, settlements) behind 47 product-shaped tools. The agent works a real matter through those systems while reading a mounted file of 6-7 synthetic documents.

Simulation only. Every matter, party, document, attorney and figure is synthetic.

Why deterministic grading

Rubric-graded agent benchmarks ask a model whether another model's prose satisfied a criterion. That conflates the grader's judgement with the agent's capability, and it cannot tell a rubric miss from a model miss.

Here every task ships an executable reference walk, and grading is a diff of world state before and after plus assertions over the recorded tool trace. A zero means the agent failed, not that a judge disagreed.

First results

Agent	Reward	Conditions failed	Tools missed	Systems never touched
Oracle (reference walk)	1.00	0	0	—
Claude Sonnet 4.5 · motion to compel	0.00	40	32	calendar, contacts, documents, efiling, matters, time
Claude Sonnet 4.5 · case chronology	0.00	29	25	calendar, contacts, matters, time

The oracle finishes every task. A frontier coding agent, given the same environment and the same mounted matter file, returns 0.0 on both — and the deterministic verifier says exactly which tools it never called and which work products it never created. The failure is not refusal or malformed output: the agent worked the litigation system and never completed the cross-application chain.

Two tasks is not a leaderboard. These are the first end-to-end runs, not a scored evaluation, and no confidence interval is claimed. They are reported because they establish the thing that matters before any leaderboard: the benchmark discriminates.

Splits and release policy

dev carries all 100 tasks with their full deterministic assertion sets. The environment image and reference walks are published alongside so results are reproducible rather than self-reported.

Running the tasks

The executable environments are published to the Harbor registry:

harbor run -d blobfishai/litigation -a <your-agent>

Intended use and licensing

Released CC BY 4.0 for benchmarking and agent training. The corpus is entirely synthetic and contains no client data. Nothing here is legal advice; every task carries an attorney-validation limitation that a correct answer must preserve.
