session_resume

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

No annotations are provided, so the description bears full responsibility. It does not disclose preconditions (e.g., session must be suspended), side effects, permission requirements, or error conditions. The resume operation implies state change but is not elaborated.

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 very short (3 lines in a docstring format) and front-loaded with the purpose. However, the 'Returns' section is vague ('Session status'), which is acceptable since an output schema exists. Could be more structured for agent scanning.

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 role in session management and the existence of an output schema, the description is incomplete. It fails to mention expected session state (suspended vs active), error cases, or integration with other session tools. A user would need additional context.

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 0%, and the description only repeats the parameter name ('session_id') with minimal context ('Session ID'). It does not explain how to obtain a session_id, format restrictions, or the meaning of the parameter beyond the schema.

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 verb-resource combination 'Resume a suspended derivation session', which distinguishes it from sibling tools like session_start, session_abort, and session_status.

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?

No guidance on when to use this tool versus alternatives (e.g., session_start for new sessions, session_abort for aborting). The description implies usage but does not specify prerequisites or exclusions.

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