search_prefect_docs

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

With no annotations, the description must disclose behavior itself. It does so by stating it returns 'search results or an error with suggestion to run 'colin run'', which covers expected outcomes and error handling. The 'real-time' mention implies network dependability, though it does not elaborate on latency or side effects. This is reasonable transparency for a simple search tool.

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 concise and well-structured with separate Args and Returns sections. Each sentence serves a purpose, from the main action to the usage context and output behavior. There is no filler, making it easy for an agent to parse quickly.

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 tool with one parameter and an output schema, the description covers the essentials: what it does, when to use it, and what to expect. The mention of 'Prefect MCP server' and 'colin run' adds context, though the meaning of 'colin' is not explained. Overall, it is sufficiently complete for an agent to invoke the tool correctly.

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 schema has one parameter 'query' with no description (0% coverage). The description compensates by including an Args section that explains 'query: Search query for Prefect docs.' This adds meaning beyond the schema, but it is minimal—no format, examples, or constraints are given. This is adequate for a simple string parameter but not exemplary.

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 states 'Search current Prefect documentation' with a specific verb and resource. It distinguishes itself from sibling tools like read_dag or lookup_concept, which serve different purposes. The addition of 'real-time queries beyond what Colin pre-compiled' further clarifies the tool's unique role.

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 phrase 'For real-time queries beyond what Colin pre-compiled' provides a clear context for when this tool should be used. It implies a dynamic search scenario and hints at a fallback via 'colin run'. However, it does not explicitly discuss exclusions or alternative tools, so it falls short of a perfect score.

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