build_analysis_brief

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

No annotations provided, so the description carries the full burden. It indicates the tool builds files and is a scaffold in agent_first mode, implying it requires agent action, but does not disclose side effects, permissions, or error 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 two concise sentences, each adding distinct information. 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?

Given the tool's simplicity (one parameter, no nested objects) and the presence of an output schema, the description is somewhat adequate but could better explain the relationship with sibling tools and the 'run_id' parameter.

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 input schema has one required parameter 'run_id' with 0% schema description coverage. The description adds no information about what 'run_id' is or how to obtain it, leaving the agent without 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 clearly states the tool builds 'analysis_brief.json and .md', specifying the output files. However, it lacks differentiation from the sibling 'finalize_analysis_brief', which likely completes the brief.

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?

It mentions 'In agent_first mode this is a scaffold the agent must fill explicitly', providing context about its use in a specific mode, but gives no guidance on when to use this tool vs alternatives like 'finalize_analysis_brief'.

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