Load Webpack Stats

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

With no annotations, the description carries the burden of behavioral disclosure. It reveals that the tool is stateful by linking to a build loaded with load_build_stats and that it unlocks other tools. However, it does not mention failure modes, idempotence, or what happens if the build is not available, leaving some behavioral gaps.

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?

Two sentences deliver the core action, the prerequisite, and the downstream impact with no filler. The information is front-loaded and every clause earns its place.

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 one-parameter loader with no output schema, the description covers what the tool does, how it connects to the build lifecycle, and which tools become available afterward. It does not describe the return value, but that omission is minor given the tool's enabling role and clear input contract.

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% and the single buildId parameter has a clear description: it is returned by load_build_stats and determines the stats.json directory. The tool description adds workflow context but no additional parameter-level meaning, so the baseline of 3 is appropriate.

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 names a specific verb and resource: parsing the webpack module stats file and linking it to an already-loaded build. It also distinguishes the tool from siblings by listing exactly which stats-powered tools it unlocks, making its role in the workflow clear.

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 clearly states the prerequisite of calling load_build_stats first and identifies when this tool is needed by naming the downstream tools it enables. It does not explicitly state when not to use it or name alternatives, but the context is strong enough for an agent to route correctly.

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