post_silence

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It states a write operation (create/update) but fails to explain side effects, idempotency, permission requirements, or how updates are identified (likely by ID). The description is minimal and lacks crucial behavioral context.

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 extremely concise (one sentence) but omits necessary details about the parameter, behavior, and usage context. While front-loaded, it fails to justify its brevity by providing essential information, making it insufficient rather than efficiently concise.

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 has a single complex nested parameter and no output schema or annotations, the description is woefully incomplete. It does not define the structure of the silence object, specify any field requirements, or describe the response, leaving the agent with significant ambiguity.

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 a single parameter 'silence' with no description and allows additional properties (0% schema description coverage). The description does not add any meaning or constraints to this parameter, leaving the agent without guidance on what fields or values are expected.

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 can 'Post a new silence or update an existing one,' identifying its dual create/update nature. This distinguishes it from sibling tools like delete_silence (deletion) and get_silences (retrieval). However, the verb 'post' is somewhat ambiguous and could be more precise.

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?

No explicit guidance on when to use this tool over alternatives. The description does not mention prerequisites, context, or when not to use it (e.g., for reading silences). Usage is only implied by the action statement.

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