List images

list_images
Read-onlyIdempotent

The account's images, newest first: uploads, images found by page scans, and re-runs. Filter by status, by source (upload or scan) or by one scan's id. Pages of up to 100; ask for the next page while page is below last_page. For one image whose id you already have, call get_image instead.

Input Schema

pageNoThe page to read, starting at 1 (the default).
scanNoOnly the images one page scan found, by the id scan_page returned.
sourceNo"upload" for images that were sent, "scan" for the ones page scans found.
statusNoOnly images with this status. queued and optimizing are still running; completed, already-optimized, failed and cancelled are finished.
per_pageNoImages a page, from 1 to 100. 15 by default.

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds behavioral context beyond the annotations: the ordering ('newest first'), the inclusion of re-runs, the pagination cap of 100, and the 'ask for the next page while page is below last_page' rule. It doesn't describe the output schema, but an output schema exists, so that burden is already carried.

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 sentences, front-loaded with the core purpose and ordering, then filters, then pagination, then the sibling alternative. Every sentence earns its place and there is no repetition of schema or annotation content.

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?

For a read-only list tool with a rich output schema, 100% parameter coverage, and annotations covering safety, the description is complete. It covers what the tool returns (images, newest first), how to filter, how to paginate, and when to use a sibling instead. Nothing an agent needs to call it correctly is missing.

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?

Schema description coverage is 100%, so the schema already documents all five parameters. The description adds a little semantic value by grouping filters ('by status, by source (upload or scan) or by one scan's id') and by noting the pagination rule, but it doesn't add meaning beyond what the schema already provides for each parameter. Baseline 3 is appropriate.

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?

The description states a specific verb ('list') and resource ('the account's images'), and immediately distinguishes the tool's scope: uploads, page-scan images, and re-runs, newest first. It also names the sibling get_image as the alternative for a single known image, so an agent can tell this list tool apart from the rest of the sibling set.

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

Usage Guidelines5/5

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

The description explicitly says when to use this tool vs get_image ('For one image whose id you already have, call get_image instead'), and gives concrete filtering guidance by status, source, or scan id. It also explains pagination behavior ('ask for the next page while page is below last_page'), which is actionable usage context.

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