release_role

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

No annotations provided, so description carries full burden. It mentions sessions auto-release after 60 minutes, providing helpful timeout behavior, but does not disclose whether the action is reversible, required permissions, or side effects on session data.

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?

Description is concise: one sentence with parenthetical detail and a separate sentence about auto-release. No redundant information, front-loaded with the main action.

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?

Missing return value description (e.g., success confirmation, error states) and preconditions (session must exist, ownership). The auto-release note adds context but overall leaves gaps for a tool with no output schema and no annotations.

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 coverage is 50% (session_id lacks description). The description adds value by elaborating on the summary parameter ('what was done, what is pending, next step'), exceeding the schema's brief 'Closing summary for the audit trail'. session_id remains implicit but is a standard identifier.

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 tool releases an open Role Session with a closing summary, specifying the summary content. It does not explicitly differentiate from sibling tools like assume_role, but the action is distinct.

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 implies use when an open role session exists, but does not provide explicit when-to-use or when-not-to-use guidance, nor mention alternatives like waiting for auto-release.

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