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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the agent knows this mutates state. The description adds useful context beyond that: the deployment status becomes 'dismissed' and the reason is persisted as learning feedback. It does not mention reversibility or required permissions, so it is adequate but not rich.

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?

Three short sentences, front-loaded with the core action before the effect and the example utterances. No padding, though the trigger-phrase list is slightly redundant with the already-clear purpose statement.

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 mutating tool with no output schema and full annotation coverage, the description explains the action, its side effects, and the feedback-learning consequence. It omits what happens to the underlying PR/branch afterwards, but nothing critical to correct invocation is missing.

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%, so the schema already documents reason, customerId, and deploymentId, including the superadmin scoping note. The description adds little parameter-level meaning beyond restating that feedback is optional; baseline 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 (reject/dismiss) plus the target resource (a pending deployment/PR) and the effect (status set to dismissed). It is unambiguous what the tool does, though it does not explicitly differentiate itself from approval-flow siblings such as decide_approval or request_approval.

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?

Provides trigger phrases ('reject this PR', 'dismiss this deployment', 'I don't want this change') and the implicit constraint that the target must be pending, which aids invocation. However, it never names an alternative tool or explains when to use this versus decide_approval or request_approval, leaving routing to inference.

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