15 tools, verified live

Pulled straight from the server with tools/list on 2026-10-17.
searchread-only

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.

describeread-only

Input schema, limits and examples of one ComputeFirst catalog tool, by id and version.

executeread-only

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_batchread-only

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 e

savingsread-only

Savings totals, optionally for one model: with a key, the account's measured and estimated totals; otherwise community verified totals. Unmeasured is not zero.

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.

request_tool

Ask for a tool that does not exist yet: the task, optionally example input and output. Optional contact_email (with email_consent:true), only if the person wants one email when it ships. Leave out secrets.

subscribe

Subscribe an email to new-tool announcements, only when the person asks for them (consent:true). Every email has an unsubscribe link.

sign_in

Only when the person explicitly asks for a free account (consent:true): creates one for their email (unverified) and returns an agent key once, for saved tools, history, personal savings and a higher limit. The person stores the key in their client settings; do not repeat it in the conversation. newsletter:true only if they ask.

profileread-only

The signed-in account: keys, privileges and tool-request status. Without a key: signed_in:false and the optional extras.

activityread-only

The account's recent calls and outcomes; pass next as before for older ones. Without a key: signed_in:false.

list_saved_toolsread-only

Tools saved in the account's library (id, version, note). Without a key: signed_in:false and no tools.

save_tool

Save a tool id and version to the account's library, with an optional note (saving again replaces the note). Without a key nothing is saved.

remove_saved_toolcan modify

Remove a tool id and version from the account's library. Without a key nothing changes.

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.
