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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds genuine value beyond that: it discloses that the webhook_secret is masked in the response, telling the agent it cannot retrieve a usable secret through this tool. Pagination and empty-result behavior are not mentioned.

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?

Two short sentences with zero filler. The scope (project) is front-loaded, and the read-only and masking facts follow immediately in descending order of importance.

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?

For a two-parameter read-only list tool with full schema coverage and complete annotations, the description covers scope, safety, and the mask on webhook_secret. Only minor details such as pagination or what an empty list looks like are absent, and with no output schema these are small gaps.

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%, and both parameters (context and project_id) are fully documented in the schema, including a detailed word-count contract for context. The description adds no parameter-level semantics beyond this, so the baseline of 3 applies.

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?

States a specific verb (List) and resource (deploy-provider webhooks) scoped to a project, and even enumerates the provider types (Vercel, Netlify, manual). It does not explicitly differentiate itself from siblings like create_deploy_integration, delete_deploy_integration, or test_deploy_integration, but the verb makes the distinction obvious.

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?

There is no explicit guidance about when to call this tool versus test_deploy_integration, create_deploy_integration, or delete_deploy_integration. Usage is only implied by the verb 'List', and no preconditions or exclusions are stated.

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