Check work you received

check_received_work

Privately check a received file against a template, plain-word requirements (need), explicit criteria, a saved contract, a check pack, or a saved report_token (adds a rerun delta). A check_pack_slug without check_pack_version uses the version pinned by bounty_id when supplied, otherwise the current version. Returns pass, fail, or could_not_verify for each declared check. A failed report offers rework.api (the bounty_post body for a rework bounty) and, while held payments are on, settlement (the settlement create body that holds payment until a delivery passes the same checks). Nothing is stored unless save is true, which returns report_url. Each caller gets 20 free checks a month of up to 500 rows each; beyond that the call answers 402 with payable terms when paid checks are available.

Input Schema

Name	Required	Description	Default
`mime`	No	Optional media type.
`need`	No	Acceptance criteria in plain words, drafted into checks the same way as the website, from these words and the delivery's column names only. The response lists the checks that ran; send them as criteria to repeat them exactly.
`save`	No	Opt in to a shareable, re-runnable report.
`content`	Yes	Delivery content as UTF-8 text or base64. The whole JSON-RPC request must be at most 4.4 MB on the hosted server, so a base64 file can be up to 3 MB decoded; larger uploads are rejected with HTTP 413.
`criteria`	No	Explicit machine checks returned by an earlier check.
`encoding`	No		utf8
`filename`	Yes	Filename including its extension.
`bounty_id`	No	Your own bounty: runs its pinned checks. Or optional context for check_pack_slug.
`contract_id`	No	Accepted bounty id from your saved contract library; requires Bearer authentication on the MCP connection.
`template_id`	No
`report_token`	No	Reuse the saved criteria structure and origin. Supply source_context again for source-dependent checks.
`source_context`	No	Source URLs, glossary, rubric, or reference sample. Required by rubric agreement and saved glossary reruns.
`check_pack_slug`	No	Use criteria from a public check pack.
`check_pack_version`	No	Pack version to use. Omit to use the version pinned by bounty_id, or the current version when bounty_id is absent.

TDQS

A3.9/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Adds substantial context beyond the annotations: nothing is stored unless save is true (which returns report_url), return values are pass/fail/could_not_verify, failed reports offer rework.api and settlement bodies, and there is a 20-free-checks/month quota with 402 terms when exceeded. This is exactly the behavioral detail annotations alone cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the core purpose well, but it is a single dense paragraph packing sourcing modes, defaults, return values, rework/settlement, and rate limits. Much is necessary, yet the run-on structure makes it harder to scan than a segmented layout would.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 14-parameter tool with no output schema, the description covers the key return values, storage behavior, and quota/402 behavior, making it largely complete. Minor gaps remain around the exact error/failure envelope beyond the 402 case.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is high (86%), so the baseline is 3, but the description adds real meaning: the check_pack_slug/check_pack_version pinning logic via bounty_id, and that report_token reuses saved structure and adds a rerun delta. These clarify parameter interactions not obvious from the schema alone.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (check) and resource (a received file) and enumerates the six sources it can validate against. It is clearly a validation tool, though it never names a sibling (criteria_draft, contract_rerun, gate_pack) to differentiate from.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Describes the different input modes and some conditional behavior (check_pack_version defaults), but gives no explicit guidance on when to use this versus related tools like criteria_draft or contract_rerun. Usage is implied by the mode list rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
