# Extract key terms from a stack of service contracts Input: `contracts/` holds 5-8 plain-text service agreements (synthetic). Some end with one or more amendments. For each contract extract: - term_months: the initial term in months (a term stated in years counts 12 months per year). - auto_renew: true if the agreement renews automatically unless notice is given, false otherwise. - notice_days: days of notice needed to terminate or prevent renewal. - liability_cap_usd: the liability cap in US dollars. When the cap is defined by fees (for example "fees paid in the twelve (12) months preceding the claim"), compute it as monthly_fee_usd x that number of months. - governing_law: the state named in the governing-law clause, as written (e.g. "Delaware"). - Amendments at the end of a contract override the original clause they amend; apply them in order. - Numbers may be written in words, in digits, or both (e.g. "sixty (60) days"). Write `out/contracts.json`: `{"<contract file name without .txt>": {"term_months": <int>, "auto_renew": <bool>, "notice_days": <int>, "liability_cap_usd": <number>, "governing_law": "<state>"}, ...}`. ## How this run works - Work on your own: nobody will answer questions in this task, and writing to `ask/` counts against the run. - Write only under `out/`. Create `out/` if it is missing. Inputs are synthetic; don't fetch anything from the network. - Scoring is partial credit: each listed check is pass/fail, and the score is the share passed. Numbers are compared to within 0.005 unless the task says otherwise.

Read 5-8 synthetic service agreements and extract five commercial terms from each. Numbers appear as words, digits or both, some liability caps are defined as a number of months of fees, and signed amendments at the end override earlier clauses. Distractors include other day counts, percentages and a second state named in the notices clause. Original benchmark task written for usecaserank.com (not based on a specific public post). Headless, offline run on a reproducible fixture. Each run's notes say how its cost was measured (estimates are marked).

Success criteria: term_months auto_renew notice_days liability_cap governing_law amendments_applied every_contract_complete

Setup notes: Batch 16 case r04-contract-clauses (offline, synthetic inputs, seed 136610350). Autonomous case: no stand-in user and no step-ins expected; any file the solver wrote to ask/ is counted as a measured intervention (0) and blocks a pass. Prompt = TASK.md verbatim. Hidden key kept outside the solver's work dir. Scored with the case's scorer (python3 score.py WORKDIR KEYDIR, absolute paths); pass = every check true and no ask/ files. Tools: Read/Write/Edit/Glob/Grep/Bash, web disabled. Single run, no retries. 1-min load average at scoring 0.34 (8 cores). Claude Code's own reported cost for claude-haiku-5.5: $0.004759. Score: 7/7. Cost is an ESTIMATE: measured tokens x pricing.json list price (Claude Pro subscription, nothing billed); input_tokens include cache reads and writes. Single run.

Estimated cost List-price estimate; not actually billed.

The 30-day notice clause is unchanged and I kept it as `notice_days`.\n- **MSA-9432-C:** Amendment No. 1 changes governing law to Massachusetts, so that is the value. The cap is 6 \u00d7 $450.00 = $2,700.\n- **MSA-5182-D:** The cap is 12 \u00d7 $2,750.50 = $33,006. Since it does not auto-renew, `notice_days` is the 60-day termination-for-convenience notice.\n- **MSA-8541-F and MSA-9432-C:** These are non-renewing contracts with a termination-for-convenience notice, and I used that notice period (60 and 90 days) as `notice_days`.\n\nI did not write anything to `ask/`.",
