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

Annotations already establish read-only, idempotent, and non-destructive behavior. The description adds useful context that this tool provides URLs, summaries, and slugs rather than full article text, which clarifies expected output without needing to restate safety hints.

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 dense sentence with no filler. Every clause adds distinct information about content types, URLs, summaries, slugs, or the related poem tool, making it highly efficient.

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 zero-parameter read-only index, the description covers the main content buckets and points to the correct sibling for reading poems. It is slightly ambiguous whether the trailing platforms also come with URLs and summaries, but this is a minor gap given the tool's simplicity.

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?

The input schema is empty with zero parameters, so there are no parameter semantics to explain. A baseline of 4 is appropriate for a no-parameter tool where the schema has already covered everything.

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 clearly inventories the tool's content: essays with URLs/summaries, all 29 poems with URLs/slugs, and additional platforms like Medium, LinkedIn, Quora, and dev.to. It also distinguishes itself from micah_boswell_poem by naming that sibling, though it lacks an explicit verb like 'lists' or 'returns'.

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?

It explicitly tells the agent to pass a slug to micah_boswell_poem to read a poem, providing clear routing guidance for poem content. It does not discuss when to prefer this tool over search_micah_boswell or micah_boswell_profiles, so it is not fully comprehensive.

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