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

Annotations already carry the safety profile (readOnly, non-destructive, not open-world), yet the description adds real value beyond them: non-persistence ('Nothing is saved'), a cost/plan disclosure ('Uses one AI help call from the plan'), and partitioning semantics ('Every note goes in exactly one group'). The AI-call cost note is exactly the kind of trait annotations cannot express.

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?

Three short, front-loaded sentences; the core behavior leads and the constraints follow. The workshop example is repeated verbatim from the notes parameter description, which is minor waste, but nothing is padded.

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?

There is no output schema, so the description should carry return-format information. It hints at the shape ('each group gets a short title') but never states concretely what comes back (a list of groups with their assigned notes), leaving the response structure partly implied for a tool whose whole purpose is restructuring input.

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 description coverage is 100%, so both parameters (notes, title) are fully documented in the schema itself, including item length and count bounds. The description adds only a redundant example and nothing about format or constraints beyond the schema, so the baseline 3 applies.

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?

Specific verb (group) and resource (notes) with the organizing dimension (by theme) stated explicitly, plus a concrete example ('sticky notes from a workshop'). It reads as a distinct operation, but it does not name or contrast itself with the nearest sibling (notes_to_flow), so an agent gets no explicit routing cue.

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 workshop-sticky-notes example implies the intended context, so use is inferable. However, there is no statement of when to prefer this over alternatives such as notes_to_flow or notes_to_flow pipelines, and no exclusions or prerequisites.

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