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 updates webhook properties, implying mutation, but doesn't cover critical aspects like required permissions, whether changes are reversible, error handling, or rate limits. For a mutation tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 front-loads the core action ('Update an existing webhook') and specifies the updatable elements. There is no wasted text, and it directly communicates the tool's purpose without redundancy or unnecessary detail.

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's complexity as a mutation operation with no annotations and no output schema, the description is incomplete. It lacks information on behavioral traits (e.g., permissions, side effects), output values, and usage context. While the schema covers parameters well, the overall description doesn't compensate for the absence of structured data on behavior and results.

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%, with all parameters well-documented in the input schema (e.g., 'webhook_id' as the ID to update, 'url' as a new HTTPS URL). The description adds minimal value by listing updatable fields ('URL, events, or active status'), which aligns with the schema but doesn't provide additional syntax or format details. Baseline 3 is appropriate given high schema coverage.

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 action ('Update') and resource ('an existing webhook'), specifying what can be updated ('URL, events, or active status'). It distinguishes from siblings like 'barevalue_webhook_create' and 'barevalue_webhook_delete' by focusing on modification rather than creation or deletion. However, it doesn't explicitly contrast with all siblings (e.g., 'barevalue_webhook_rotate_secret'), keeping it from a perfect score.

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. The description doesn't mention prerequisites (e.g., needing an existing webhook ID), exclusions, or comparisons to siblings like 'barevalue_webhook_create' for new webhooks or 'barevalue_webhook_delete' for removal. Usage is implied by the verb 'Update,' but explicit context is lacking.

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