dashclaw_session_end

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

No annotations provided, so description must cover behavioral traits. It mentions 'clean lifecycle boundary for governance reporting' which adds context about impact on governance. However, it does not detail side effects like what happens to associated data or whether the session is destroyed. The description is adequate but not comprehensive.

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?

Two sentences: first states action, second gives usage guidance and context. Every sentence earns its place. No redundancy. Efficient and front-loaded.

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?

Description covers purpose and usage, but lacks information about return values, error handling, idempotency, or validation of session state. Given no output schema, missing these behavioral details makes it incomplete for a mutation tool.

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 description does not need to repeat parameter meanings. The description implies usage of 'session_id' and 'status' by saying 'close a session and update its status', but does not mention 'summary'. This adds minimal value 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?

Description clearly states the tool's purpose: 'Close a DashClaw session and update its status.' The verb 'close' and resource 'session' are specific. The tool name and description naturally distinguish it from sibling tool 'dashclaw_session_start' as its counterpart.

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 states when to use: 'Call this when the task is complete or if the session needs to be marked as failed.' This provides clear context. However, it does not mention alternatives or when not to use it, such as if the session should remain open.

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