gimp_filter_describe

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

There are no annotations, so the description carries the behavioral disclosure burden. It does this well by stating that the tool reports properties rather than mutating anything, and by listing the kinds of information returned (names, types, ranges, defaults). It remains brief but honestly conveys a read-only inspection behavior.

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

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

The description is one tight sentence with no filler. It front-loads the verb and resource, then adds a parenthetical detail list that earns its place by clarifying what will be described.

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

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

For a simple one-parameter read-only tool, the description captures the essential behavior and output categories, and an output schema exists to document return shape. However, it omits practical setup context, such as where valid GEGL operation names come from or how to discover them (e.g., via gimp_filter_search), so an agent may still be unsure what value to pass for 'op'.

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

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

Schema coverage is 0% and the description only loosely connects 'op' to 'GEGL operation'; it never defines op as an operation identifier or gives acceptable formats/examples. The word 'op' plus the description provides partial semantic context, but it does not adequately compensate for the missing schema documentation.

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

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

The description uses a specific verb ('Describe') and resource ('GEGL operation's properties') and enumerates the relevant output categories (names, types, ranges, defaults). This distinguishes it from siblings like gimp_pdb_describe, which targets PDB procedures, and gimp_filter_search, which searches rather than describes.

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

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

The description gives no explicit guidance on when to use this tool versus alternatives such as gimp_filter_search, gimp_pdb_describe, or gimp_apply_filter. An agent can infer a use case from the purpose statement, but there is no stated when-to-use or when-not-to-use context.

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