browser-server-console

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

No annotations are provided, so the description carries the full burden of disclosing behavioral traits. It states what the tool does (spawns a server, captures console) but does not disclose side effects such as server lifecycle/cleanup, blocking behavior, rate limits, or what happens to existing servers. This is a significant gap for a tool that starts a server.

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, efficient sentence that immediately conveys the core purpose and actions. It contains no fluff or redundant phrasing, and every word contributes meaning.

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 seven parameters and the absence of annotations and an output schema, the description is relatively minimal. It does not explain what the tool returns, how console output is delivered, or whether the server is automatically stopped. The parameter schema covers the 'how' but the overall usage context remains incomplete.

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 100%, so the schema fully documents all seven parameters including defaults and semantics. The description adds no additional meaning beyond what the schema already provides, so the baseline score 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 uses a specific verb ('Spawn') and resource ('Express static server') and clearly states the second function ('capture console output'). This distinguishes it from the sibling tool 'browser-console', which likely focuses only on console capture without serving a directory.

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 does not explicitly state when to use this tool versus the sibling tool 'browser-console'. It implies usage for serving static content and capturing console output, but there are no exclusions or alternative recommendations, leaving the agent to infer the appropriate context.

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