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

Annotations already signal write/destructive/idempotent behavior; the description adds context beyond that with 'RELEASE-level write' and the specific state transitions. This helps the agent understand the operation's scope and impact. No contradiction with annotations.

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 two sentences, front-loaded with the primary action and including only necessary operational details. No wasted words.

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 covers the operation, endpoint, state changes, and release-level write context. While it does not describe return values, there is no output schema and the operation is a straightforward write. The PAUSE/PAUSED mismatch is a minor completeness gap.

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?

The input schema already provides 100% parameter coverage, including 'ID from the matching list call' and the JSON:API body schema with the phasedReleaseState enum. The description adds little beyond what the schema provides, and it introduces a minor inaccuracy by saying 'PAUSE' instead of the schema's 'PAUSED'.

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 and resource: 'Pause, resume or complete a phased release' and specifies the state changes via 'Set phasedReleaseState to PAUSE, ACTIVE or COMPLETE.' It distinguishes itself from sibling tools like create and delete by focusing on updating an existing phased release. The minor PAUSE/PAUSED inconsistency does not obscure the purpose.

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 clear context for when to use the tool: to pause, resume, or complete a phased release, with the specific state values listed. It does not explicitly address exclusions or alternatives, but the scope is narrow and the intended use is obvious.

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