Summarize Results

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

No annotations are provided, so the description must fully disclose behavior. It mentions 'deterministic' but lacks details on side effects, permissions, or what the summary contains. For a mutation tool, more transparency is needed.

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 a single sentence of 14 words, efficiently conveying the purpose without unnecessary detail. It is front-loaded and every word serves a purpose.

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?

With no output schema and no annotations, the description minimally explains input but omits details on the output structure or behavior. Given the low complexity, it is adequate but could be improved by describing what the summary contains or its format.

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 parameter 'result' is an array of strings with schema description. The description adds context that it expects 'result JSON documents', which goes beyond the schema's 'local paths to result JSON documents' by specifying the type of documents. This adds meaningful semantic value.

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 the tool creates a deterministic summary_result document from one or more result JSON documents, specifying the verb 'create', the resource 'summary_result document', and the inputs. It distinguishes from sibling tools like 'compare' or 'prioritize' by focusing on summarization.

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 description implies usage for combining multiple result documents into a summary but does not explicitly state when to use this tool versus alternatives like 'coverage' or 'compare'. No guidance on when not to use or prerequisites are provided.

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