update_release_time

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

No annotations are provided, so the description carries the full burden. It indicates mutation ('Update') and a precondition, but does not disclose side effects, error behavior, required permissions, or whether changes are reversible. This is insufficient for a mutation tool.

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, well-constructed sentence that states the core functionality and a critical precondition. Every word adds value, with no repetition 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?

The description lacks information about return values, error handling, or additional behavioral context. For a tool that modifies release scheduling, knowing the outcome (success/error) and prerequisites beyond state is important. It feels incomplete.

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 baseline is 3. The description does not add parameter-specific information beyond what the schema already provides; it only restates the overall purpose. No additional value for parameter semantics.

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 scheduled release time') and the resource ('release time' of an app), and includes a critical precondition ('Only valid when app is in Releasing state'). This distinguishes it from sibling tools that handle phased releases or other aspects.

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?

The description provides a usage condition ('Only valid when app is in Releasing state') but does not explicitly guide when to use this tool over siblings like 'change_phased_release_state' or 'update_phased_release'. It offers context but no exclusions or alternatives.

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