Measured tools (10)

• create_result_reference

  Authorize one recipient client_id to read one owned result with its own credential. Returns a credential-free, expiring reference for agent handoff. Owner access stays in the configured header. Requires explicit intended recipient; no permission to other jobs, deletion or resharing.

  Parameters:

  • recipient_client_id (required) — string — Public client identifier provided by the intended recipient through an authorized connection. Never their token.
  • job_id (required) — string
  • request_key (required) — string — Stable reference idempotency key. Reuse with identical job, recipient and requested lifetime.
  • ttl_seconds — integer — Reference lifetime, also bounded by the job and both access credentials' expiry.

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• delete_job destructive

  Delete the owner's stored result content. Retains an idempotency tombstone until expiry and does not reset quotas. Configure the owner's bearer access header.

  Parameters:

  • job_id (required) — string

  Hints: read-only no · destructive yes · idempotent not declared · open-world not declared

• get_catalog read-only

  Read public capabilities, free allowances, access bootstrap, privacy, retention and HTTP discovery routes. No access credential required.

  Hints: read-only yes · destructive no · idempotent not declared · open-world not declared

• get_job read-only

  Recover the original complete private CSV or audit result using its job_id and the owner's bearer access header. Results expire within 24 hours and cannot outlive access.

  Parameters:

  • job_id (required) — string

  Hints: read-only yes · destructive no · idempotent not declared · open-world not declared

• get_result_reference read-only

  Retrieve the full shared result using the nominated recipient's configured bearer header. The reference alone grants no access. Expired, revoked or deleted results are unavailable.

  Parameters:

  • reference_id (required) — string

  Hints: read-only yes · destructive no · idempotent not declared · open-world not declared

• resolve_capability read-only

  Resolve an exact canonical Wever service_id to its maintained connection metadata, contract, limits and access steps. Unknown identities are rejected; no caller-supplied URL is fetched. Does not verify live availability or authorize execution.

  Parameters:

  • service_id (required) — string — Exact canonical service_id from capability search, at most 96 UTF-8 bytes. Never a URL or credential.

  Hints: read-only yes · destructive no · idempotent not declared · open-world not declared

• revoke_result_reference destructive

  Owner revokes future retrieval through one shared result reference. Repeating this action is safe; previously downloaded copies cannot be recalled.

  Parameters:

  • reference_id (required) — string

  Hints: read-only no · destructive yes · idempotent not declared · open-world not declared

• search_capabilities read-only

  Find maintained Wever capabilities by a short task description or keyword. Returns fixed known services with connection details, contracts, limits and access steps. Does not execute work, grant permissions, search the whole web, or verify live availability.

  Parameters:

  • query (required) — string — Nonblank query of at most 160 UTF-8 bytes. Deterministic keyword matching over maintained Wever services only.
  • limit — integer

  Hints: read-only yes · destructive no · idempotent not declared · open-world not declared

• submit_audit

  Audit bounded CSV against caller-supplied expected records with explicit grouping, exact source references, lineage and integrity checks. A completed audit can report mismatches or blocked parsing. Inspect result.status, comparison, ambiguities and unsupported rules. No factual verification or inferred transformations.

  Parameters:

  • csv_text (required) — string — At most 8192 UTF-8 bytes, 20 data records, 30 columns and 4096 UTF-8 bytes per cell. Exact strings are preserved.
  • expected_records (required) — array — Ordered expected records; field names and values are strings of at most 4096 UTF-8 bytes each.
  • request_key (required) — string — Stable idempotency key shared across CSV and audit. Reuse only with identical input for the same capability.
  • rule — object — Supports {kind: preserve_rows} or {kind: explicit_groups, groups: [{source_records: [1,2], concatenate: {column: separator}}]}. Source indexes are one-based and exclude the header. Invalid or unsupported rule options are findings with preserving fallback. No grouping is inferred. At most 8192 UTF-8 bytes.
  • requested_rules — array — Descriptive requests, each at most 200 UTF-8 bytes. Every entry is reported unsupported; these do not authorize extra transformations.
  • source_metadata — object — Descriptive metadata only, each value at most 200 UTF-8 bytes. No URL fetching or encoding conversion.

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared

• submit_csv

  Normalize bounded CSV using explicit column rules. Returns a complete private job and checked CSV. Configure bearer access in the client header. Reuse request_key on retries.

  Parameters:

  • csv_text (required) — string — At most 16 KiB UTF-8 and 100 data records
  • schema (required) — object
  • request_key (required) — string — Stable idempotency key shared across CSV and audit. Reuse only with identical input for the same capability.

  Hints: read-only no · destructive no · idempotent not declared · open-world not declared
