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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and a closed-world scope, so the safety profile is covered. The description adds useful behavioral context by disclosing the return format (ready-to-use Markdown links and summaries), which matters since there is no output schema, but says nothing about ranking, matching quality, or behavior on an unrecognized topic.

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?

A single well-formed sentence that front-loads the accepted inputs and closes with the output contract — no filler. It is efficient, though it packs two distinct ideas into one clause without separate structure.

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 simple two-parameter read-only tool with no output schema, the description covers input modes and the return format adequately. Minor gaps remain: no note on result ordering/relevance, and no mention of what happens when no related tutorials exist.

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% for both parameters, so the schema already documents limit (range/default) and the topic_or_url dual mode. The description only echoes the accepted input forms already stated in the schema, adding no new syntax or format guidance.

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 names a specific verb (find) plus resource (related kirupa.com tutorials) and states both accepted input forms (topic/concept or existing URL/slug) and the output shape (Markdown links with summaries). It does not, however, explicitly contrast itself with the sibling search_tutorials or get_tutorial, so an 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?

Usage is implied by the dual input modes — use a topic phrase for discovery, or a URL/slug to expand from an existing tutorial. There is no explicit statement of when to prefer this over search_tutorials or get_tutorial, and no exclusions or prerequisites are given.

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