Tools of ComputeFirst
	Description		Read-only	Idempotent	Open world
`activity`The account's recent calls and outcomes; pass next as before for older ones. Without a key: signed_in:false.	The account's recent calls and outcomes; pass next as before for older ones. Without a key: signed_in:false.	No	Yes	Yes	No
`describe`Input schema, limits and examples of one ComputeFirst catalog tool, by id and version.	Input schema, limits and examples of one ComputeFirst catalog tool, by id and version.	No	Yes	Yes	No
`execute`Run one ComputeFirst catalog tool by id and version with its JSON input. Returns the deterministic result and an unmeasured savings receipt. Limits: computefirst.net/docs#limits.

`execute_batch`Run 1–20 ComputeFirst catalog tools in one request. Optional bindings fill an input key from an earlier result (JSON Pointer); include_result:false omits an intermediate. Steps after a failed dependency are skipped; nothing is retried automatically. Each success is one execution. Inputs, results and response: 256 KiB each. A factory work budget can skip an item with batch_work_limit; finance and exact decimal power/root/expression tools use the full factory allowance. Send additional factory operations separately. Split refused work; successful items are never retried automatically.	Run 1–20 ComputeFirst catalog tools in one request.

`feedback`Tell ComputeFirst what helped or went wrong (a missing tool fits request_tool). A stable request_id makes retries safe. Leave out secrets and raw data.

`report_savings`Optional, for the person: your model id and, if known, your own estimate of the tokens a call saved (estimated_tokens_saved). Returns its dollar value at public list prices; unknown stays null. A measured comparison adds task_id, baseline_id, baseline, actual, whole_task:true, execution_ref.

`search`Search the ComputeFirst catalog (computefirst.net/tools) with an English task. Returns up to 5 tools (3 by default) with id, version and a 0–1 score; a confident first match includes its input contract. No match: request_tool can ask for one.
