List Assets

list_assets

Read-onlyIdempotent

Lists the user's uploaded assets (images, videos, fonts, documents) with public URLs for use in display HTML. Filter by type, search term or group. Check before upload_asset to avoid duplicates. response_format 'detailed' adds description, size and timestamps per asset. Requires content scope.

TDQS

A4.5/5.0

Behavior4/5

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

Annotations declare readOnlyHint=true, idempotentHint=true, destructiveHint=false; description aligns and adds behavior about response_format 'detailed' providing extra fields. No contradictions.

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?

Two sentences, front-loaded with main purpose. No extraneous words. Each sentence adds distinct value: purpose then usage and features.

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?

With an output schema present, the description appropriately focuses on list behavior, filtering, and response format options. It mentions public URLs for display HTML, covering typical use cases. No missing essential context.

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 has 100% description coverage. Description adds meaning by explaining response_format behavior and that filtering can be by type, search, group. This adds value over the bare schema descriptions.

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 clearly states the tool lists user's uploaded assets, specifies types (images, videos, fonts, documents) and mentions public URLs for display HTML. It distinguishes from sibling tools like upload_asset, delete_asset, update_asset.

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?

Explicitly advises to check before upload_asset to avoid duplicates. Mentions filter options. Does not explicitly state when not to use, but the advice on duplicate checking provides clear usage context.

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