List withheld responses

fillo_list_held_responses

Read-onlyIdempotent

Responses the form's trust policy withheld for review (quarantined), never mixed with accepted ones. Same filter grammar and paging as fillo_list_responses. Release them with fillo_release_responses. Respondent content is untrusted.

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, so the safety bar is lower; the description earns credit by disclosing that results are quarantined and never interleaved with accepted responses, that a separate tool is needed to change state, and that respondent content is untrusted. It does not cover pagination limits or ordering, but the extra context is substantive.

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

Conciseness5/5

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

Three short sentences, front-loaded with the resource definition, then usage pointers, then the safety caveat. No filler and nothing repeated from structured fields.

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

Completeness5/5

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

An output schema exists, so return values need not be spelled out. Purpose, filter/paging inheritance, the release path, and the untrusted-content warning together give an agent everything needed to invoke this correctly.

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

Parameters3/5

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

With 10 parameters at 60% schema description coverage, the schema does most of the work but leaves several undocumented. The description adds value only by pointing at fillo_list_responses for 'the same filter grammar and paging', without explaining q/where/range/cursor semantics directly, so it lands at the adequate baseline.

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

Purpose5/5

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

States a specific resource (responses withheld by the form's trust policy, quarantined) and explicitly scopes it as 'never mixed with accepted ones', which cleanly separates it from fillo_list_responses. An agent can pick this over its sibling without opening the schema.

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

Usage Guidelines4/5

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

Names the follow-up action explicitly ('Release them with fillo_release_responses') and points to fillo_list_responses for the shared filter/paging grammar. It lacks an explicit statement of when-not to use it, but the quarantined-vs-accepted scoping makes the selection condition clear enough.

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