Read-onlyIdempotent

Browse available photo-editing operations by category, filter group, or keyword to retrieve IDs and titles for building or validating edits in LazyRoom projects.

Instructions

Compact list of editing operations (id, title, group). Filter by category, ImageToolbox filter group (e.g. category='filter', group='blur') or keyword query (e.g. 'vignette', 'film grain', 'pixelate').

B3.2/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that the return is a 'compact list' with id, title, group, which is useful context beyond annotations, but it omits pagination behavior and any filtering edge cases.

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 the tool's purpose and return shape, followed by filtering examples. Every sentence earns its place with no wasted wording.

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

Completeness2/5

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

For a five-parameter list tool with 0% schema description coverage and no output schema, the description should cover pagination and all filters. It addresses category, group and query well but leaves limit/offset unexplained and does not contrast with describe_operations, leaving clear gaps.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate. It explains category and group with an example pairing and gives query examples, but it says nothing about limit or offset, leaving two of five parameters completely undocumented in both schema and description.

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?

The description states a specific verb and resource ('Compact list of editing operations') and names the compact fields returned (id, title, group). It does not explicitly distinguish this tool from the sibling describe_operations, so it stops short of a 5.

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?

It gives concrete filtering examples (category='filter', group='blur', query='vignette') which guide invocation, but it never states when to use this tool versus describe_operations or get_capabilities. Usage is implied rather than explicitly scoped.

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