binary.summary

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

With no annotations, the description bears full responsibility for behavioral disclosure. It only says 'Get ... summary' which implies a read operation, but offers no details about output format, side effects, performance, or whether the summary is computed on demand. This is insufficient for an agent to understand the tool's behavior.

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 4-word sentence that efficiently conveys the tool's basic purpose. It is front-loaded and to the point, though it sacrifices helpful detail for brevity.

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?

Given the absence of annotations, output schema, and parameter documentation, the description is far too minimal. It does not explain what the summary contains, how session_id connects, or what the agent can expect from the result. The tool sits among many siblings that likely need differentiation.

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 0%, yet the description adds no explanation for the sole required parameter 'session_id'. It does not clarify its provenance, format, or how it relates to the summary. The description fails entirely to compensate for the missing parameter documentation.

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 states 'Get binary/session summary' which clearly indicates a retrieval operation and identifies the resource (binary/session). It distinguishes from siblings like binary.functions or binary.strings by using the distinct term 'summary', but it does not specify what constitutes a summary, leaving some ambiguity about scope.

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 provides no guidance on when to use this tool versus alternatives such as binary.functions or session.list. It does not mention prerequisites, context, or exclusions. An agent would have to infer usage from the tool name alone.

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