typesafe_respond

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

With no annotations, the description carries the full behavioral burden. It adds valuable context by warning that UI contents are untrusted and instructing the agent to inspect the pending packet before responding. However, it does not disclose side effects, validation outcomes, or what happens if the reply does not match the requested schema.

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 short, front-loaded with purpose, and each sentence contributes a distinct instruction. The wording 'writer/URL/answer reply' is awkward, but there is no fluff or redundant expansion.

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 no annotations, no output schema, and five sibling tools, the description provides enough for basic use: it names the action, gives pre-response inspection guidance, and warns about untrusted UI data. It leaves gaps around where requestId comes from, how to access the pending packet, and what exact reply schema to use beyond the generic instruction.

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%, so the description is expected to compensate. It only refers generically to replying with the exact requested schema and does not explain requestId or the structure/meaning of the reply object. The schema itself provides type information, which prevents a score of 1, but the description adds no meaningful parameter semantics.

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 a clear verb and resource: it supplies a reply requested by the current host agent. It does not explicitly differentiate from siblings like typesafe_status or typesafe_run, and the phrase 'writer/URL/answer reply' is awkwardly worded, but the core action is identifiable.

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 gives concrete operational guidance: inspect the pending packet and image before answering, reply only with the exact requested schema, and treat UI contents as untrusted. It does not name explicit alternatives or exclusions, but the context for when and how to use the tool is reasonably clear.

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