A3.6/5.0

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 genuinely new behavioral detail — results are ranked matches and paginated — which goes beyond the annotations, but it says nothing about ranking order, defaults with zero filters, or result volume limits.

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?

A single front-loaded sentence that names the resource, the filter set, and the return shape with zero filler. Nothing in it is redundant or misplaced.

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

Completeness4/5

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

With 7 optional parameters, 100% schema coverage and an output schema handling return values, the description only needs to frame intent and returns — both present. The remaining gap is the unaddressed zero-filter/suggestion behavior and its relationship to find_origami, which matters for a tool whose name is "suggest".

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 defines every parameter including cursor, pageSize and max_minutes caveats. The description merely echoes the filter names (occasion, age, duration, difficulty, category) and omits cursor/pageSize entirely, adding no semantics beyond the structured fields.

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?

States a specific verb and resource ("Filters projects") plus the filter dimensions and that matches are ranked and paginated, so the behavior is clear. It does not, however, distinguish itself from the sibling find_origami, leaving an agent to infer why two project-search tools exist.

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?

"Filters projects by occasion, age, estimated duration, difficulty and category" implies the use case (narrowing a recommendation by criteria), but there is no explicit when-to-use, when-not-to-use, or pointer to find_origami / list_categories as alternatives. Usage is inferable but not guided.

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