delete_recovery_session

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

Annotations already signal destructiveness and idempotency, and the description adds irreversibility, ambiguity-handling guidance, and the error behavior with candidate IDs. The description and annotations align, and the additional context meaningfully exceeds what annotations alone provide.

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 front-loaded with the most important facts (permanence, irreversibility, ambiguity handling) followed by a compact selector block. Every sentence adds operational value and there is no filler or redundancy.

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?

Given the tool's destructive nature and the non-obvious selector logic, the description fully equips an agent to call it correctly: it covers user clarification, parameter selection, ambiguity resolution, and error recovery. The output schema and annotations cover remaining details, so nothing material 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 coverage is 100%, but the description adds crucial cross-parameter semantics: the selector relationship between id and session_date, the optional narrowing role of session_category, that session_category is ignored when id is given, and the exactly-one-required constraint. This goes well beyond the baseline schema descriptions.

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 states a specific verb ('Permanently delete') and a specific resource ('a recovery session log entry'), clearly distinguishing it from sibling delete/update/log tools. The title annotation adds a parallel label, and the resource is unambiguous against the large set of sibling tools.

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?

Explicitly instructs the agent on when to ask the user for clarification, how to resolve the target session using either id or session_date, and what to do if multiple sessions match. It also clearly states that exactly one of id or session_date is required, which is not reflected in the schema's required parameters.

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