explain_search_result

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

No annotations provided, so description must disclose behavioral traits. It mentions 'hybrid search' and 'explainable ranking scores' but does not state if the operation is read-only, what data is accessed, or any side effects. Incomplete for a search-related 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?

Single, well-structured sentence. Front-loaded with key action and output. No wasted words.

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 2-parameter tool with no output schema, the description gives a reasonable hint of the return type (ranking scores and evidence). However, it does not clarify if it returns a single result or multiple, and lacks details about the evidence format. Slightly incomplete for explaining search results.

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%, so baseline is 3. Description adds context about the query being used for hybrid search and returning top snippets, but does not significantly extend the parameter meaning beyond the schema descriptions.

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?

Description clearly states it runs a hybrid search and returns explainable rankings for code snippets. It distinguishes from plain search tools by emphasizing explainable scoring, but could more explicitly differentiate from similar explanation tools like explain_file.

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?

No guidance on when to use this tool versus alternatives such as hybrid_search or semantic_search. The description lacks context for when explainability is needed versus a standard search.

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