Measured tools (15)

• search read-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.

  Parameters:

  • query (required) — string
  • limit — integer
  • include_contract — boolean

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• describe read-only

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

  Parameters:

  • id (required) — string
  • version (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• execute read-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.

  Parameters:

  • id (required) — string
  • version (required) — string
  • input (required) — object
  • model — string — Optional: your model id, only so savings can be shown per model

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• execute_batch read-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 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.

  Parameters:

  • operations (required) — array
  • model — string — Optional: your model id, only so savings can be shown per model

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• savings read-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.

  Parameters:

  • model — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• 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.

  Parameters:

  • category (required) — string
  • message (required) — string
  • request_id (required) — string
  • execution_ref — string

  Hints: read-only no · destructive no · idempotent yes · open-world no

• 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.

  Parameters:

  • description (required) — string
  • contact_email — string
  • email_consent — boolean
  • example_input — string
  • example_output — string

  Hints: read-only no · destructive no · idempotent no · open-world no

• subscribe

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

  Parameters:

  • email (required) — string
  • consent (required)

  Hints: read-only no · destructive no · idempotent yes · open-world no

• 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.

  Parameters:

  • email (required) — string
  • consent (required)
  • newsletter — boolean

  Hints: read-only no · destructive no · idempotent no · open-world no

• profile read-only

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

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• activity read-only

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

  Parameters:

  • limit — integer
  • before — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_saved_tools read-only

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

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• 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.

  Parameters:

  • id (required) — string
  • version (required) — string
  • note — string

  Hints: read-only no · destructive no · idempotent yes · open-world no

• remove_saved_tool destructive

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

  Parameters:

  • id (required) — string
  • version (required) — string

  Hints: read-only no · destructive yes · idempotent yes · open-world no

• 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.

  Parameters:

  • model (required) — string
  • actual — object
  • task_id — string
  • baseline — object
  • provider — string
  • whole_task
  • baseline_id — string
  • execution_ref — string
  • estimated_tokens_saved — object

  Hints: read-only no · destructive no · idempotent no · open-world no
