Tools

• activity ~91 tokens
  The account's recent calls and outcomes; pass next as before for older ones. Without a key: signed_in:false.
• describe ~96 tokens
  Input schema, limits and examples of one ComputeFirst catalog tool, by id and version.
• execute ~167 tokens
  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 ~586 tokens
  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
• feedback ~168 tokens
  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.
• list_saved_tools ~64 tokens
  Tools saved in the account's library (id, version, note). Without a key: signed_in:false and no tools.
• profile ~67 tokens
  The signed-in account: keys, privileges and tool-request status. Without a key: signed_in:false and the optional extras.
• remove_saved_tool ~99 tokens
  Remove a tool id and version from the account's library. Without a key nothing changes.
• report_savings ~295 tokens
  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.
• request_tool ~172 tokens
  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.
• save_tool ~124 tokens
  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.
• savings ~90 tokens
  Savings totals, optionally for one model: with a key, the account's measured and estimated totals; otherwise community verified totals. Unmeasured is not zero.
• search ~149 tokens
  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.
• sign_in ~164 tokens
  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. new
• subscribe ~99 tokens
  Subscribe an email to new-tool announcements, only when the person asks for them (consent:true). Every email has an unsubscribe link.
