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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool registers a webhook but doesn't explain what happens after registration (e.g., whether it's active immediately, how errors are handled, or if authentication is required). For a mutation tool with zero annotation coverage, this leaves significant gaps in understanding its behavior and side effects.

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 efficiently structured with a clear purpose statement followed by parameter explanations. Every sentence adds value, and there's no redundant information. It could be slightly more front-loaded by integrating parameter hints into the main description, but overall it's well-organized and 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 an output schema (which handles return values), the description focuses on inputs and purpose. However, for a mutation tool with no annotations and 3 parameters, it should provide more context about behavioral outcomes (e.g., what the webhook does, error conditions). The parameter semantics are adequately covered, but overall completeness is moderate due to missing usage and behavioral details.

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 must compensate. It adds meaningful context for all three parameters: 'show' is linked to 'PODHOME_SHOWS', 'url' is specified as a 'Webhook endpoint URL', and 'action_type' is clarified with enum values 'episode_published' or 'episode_live'. This goes beyond the bare schema to explain what each parameter represents, though it could provide more detail on format constraints.

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 verb 'Register' and resource 'new webhook', making the purpose immediately understandable. It distinguishes from siblings like 'delete_webhook' and 'list_webhooks' by specifying creation rather than removal or listing. However, it doesn't explicitly differentiate from 'test_webhook' which might have overlapping concepts.

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 guidance is provided on when to use this tool versus alternatives like 'test_webhook' or 'delete_webhook'. The description lacks context about prerequisites (e.g., needing a valid show slug) or typical use cases (e.g., setting up notifications). It simply lists parameters without explaining the tool's role in the workflow.

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