analyze_video_in_session

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

No annotations are provided, so the description carries full burden. It only lists parameters without disclosing behavioral traits such as return format, destructiveness, side effects, or rate limits. For an analysis tool, information about processing time or data usage would be valuable.

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 concise, front-loaded with purpose, and uses a clean parameter list format. Every sentence serves a clear function with no redundancy or filler.

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 has 3 parameters, no annotations, and an output schema, the description adequately covers parameter meanings but is incomplete in behavioral and usage context. It does not mention what the analysis returns (though output schema exists) or any prerequisites beyond having a session.

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%, so the description must add meaning. It does so by clarifying 'session_id' as UUID of existing session, 'prompt' as analysis question/instruction, and 'timestamp_range' as optional 'MM:SS-MM:SS' format for segment analysis. This adds significant value beyond the bare 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 'Analyze' and resource 'video within session context'. It is not a tautology and implies a specific scope (existing session). However, it does not differentiate from sibling tools like analyze_local_video or analyze_youtube_video, which might share similar analysis capabilities but on different sources.

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 via parameter 'session_id' that this tool operates on an existing session, hinting it should be used after a session is created. But it lacks explicit guidance on when to use this tool versus siblings, no when-not or alternatives are mentioned.

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