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

The annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds useful return-format context ('Returns result ids'), which matters because there is no output schema, but it says nothing about result limits, ranking, or pagination.

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?

Two short sentences with zero waste; scope is front-loaded and the return-format note follows. Nothing is repeated from the schema or annotations.

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 one-parameter, no-output-schema tool with rich annotations, the description supplies scope, content coverage, and the return shape (result ids) that the missing output schema would otherwise have to carry. Only query syntax and result-limit behavior remain unaddressed.

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 0% and the single required 'query' parameter (1-200 chars) is undocumented in the schema. The description only scopes the corpus (Colin Wynd content), leaving it unclear whether 'query' expects keywords, phrases, or a person's name, and adding little meaning beyond the schema's type constraint.

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?

States a specific verb (search) and a bounded resource (everything on tarvit.com about Colin Wynd), and enumerates the covered content types: profile, articles, talks and videos. It implicitly contrasts with the narrower sibling search_writing via 'everything', though it never names a sibling outright.

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?

'Search everything' implies this is the broad discovery entry point and that narrower get_* / list_* tools serve follow-up, but no explicit when-to-use or when-not guidance is given. The agent must infer the routing decision from the sibling names alone.

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