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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description usefully discloses that the corpus is a small fixed set of sixteen items, consistent with openWorldHint=false, but adds nothing about matching behavior, partial matches, or return shape.

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?

One sentence plus a parenthetical, front-loaded with what the tool returns, then scope, then parameter behavior. No filler or restated boilerplate.

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 single optional-string, read-only lookup with full annotation coverage, the description conveys the resource, the scope, the default behavior, and the corpus size. Return format is only implied by 'question and answer pairs', which is a minor gap given there is no output schema.

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 100% and the schema already supplies the example keywords, so baseline is 3. The description adds meaning beyond the schema by specifying the default semantics of an omitted query (return all sixteen), which is behaviorally important for an agent deciding whether to pass the parameter.

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 resource (question and answer pairs) and narrows the corpus to three named areas of micahboswell.design, with a concrete size of sixteen items. It does not explicitly contrast itself with siblings like micah_boswell_facts or search_micah_boswell, so the agent must infer the boundary.

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?

Gives clear operational guidance for the one parameter: an optional keyword query filters, and leaving it empty returns all sixteen. It does not name an alternative tool for broader site search, so the when-to-use-this-vs-siblings question is only partly answered.

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