save_session

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It does not mention whether saving overwrites an existing file, requires specific permissions, or the nature of the .rv file format. It also doesn't state if the session continues after saving.

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 brief and front-loaded with the purpose and a parameter list. Every sentence earns its place, though it could be slightly expanded to cover behavioral details without becoming verbose.

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 simplicity (1 required parameter) and the presence of an output schema (which likely defines the return value), the description is mostly adequate. However, it lacks mention of overwrite behavior or error conditions, which would improve completeness.

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?

The description includes a parameter explanation for 'file_path' (Path for the .rv session file), which adds meaning beyond the input schema that only defines the type as string. However, with only one parameter and no additional details (e.g., allowed extensions), the value added is modest.

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 saves the current session to a .rv file, specifying the verb 'Save' and resource 'current session' and output file. This distinguishes it from siblings like clear_session (clear) and new_session (create new).

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., clear_session, new_session) or what prerequisites are needed. The description does not mention any context or conditions for using this tool.

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