finalize_session

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

No annotations are provided, so the description carries full burden for behavioral transparency. It mentions returning a payload but does not disclose side effects like whether the session is irrevocably finalized, if permissions are needed, or any error conditions. The description is vague about what 'finalized' means.

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 relatively short and front-loaded with the primary action. However, the structure could be improved with clearer separation of purpose and output details. Still, it avoids unnecessary text.

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?

An output schema exists, so explaining return values is not needed. The description mentions the two tools returned, which helps context. However, it lacks context about prerequisites (e.g., session must be active) and how this fits in the overall workflow among many siblings.

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?

There is only one parameter (session_id) with 0% schema description coverage. The description does not explain what session_id is, its format, or any constraints beyond being required. It adds no value over 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 tool's purpose: 'Mark a session finalized.' It specifies the verb (mark) and resource (session), and distinguishes from siblings like move_session and keep_here by mentioning them as part of the output.

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 usage context by describing the output payload that includes a prompt and two tools, suggesting this tool is used before deciding whether to move or keep the session. However, it does not explicitly state when to use versus alternatives like clear_session or start_session, nor when not to use it.

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