end_codegen_session

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions ending a session and generating a test file, but fails to describe critical behaviors: whether this action is destructive (e.g., deletes session data), requires specific permissions, has side effects like file creation, or what happens if the session ID is invalid. This is inadequate for a tool that likely performs mutations.

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 a single, efficient sentence that front-loads the core action and outcome with zero wasted words. It is appropriately sized for a tool with one parameter and clear purpose, making it easy for an agent to parse quickly.

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 lack of annotations and output schema, and the tool's likely complexity (ending a session and generating files), the description is incomplete. It does not explain the result format, error conditions, or behavioral nuances, leaving significant gaps for the agent to operate effectively in a code generation 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 100%, with the single parameter 'sessionId' well-documented in the schema. The description does not add any semantic details beyond what the schema provides (e.g., format or source of the ID), so it meets the baseline score of 3 for high schema coverage without extra value.

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 with a specific verb ('End') and resource ('a code generation session'), and it adds the outcome ('and generate the test file'). However, it does not explicitly distinguish this tool from its sibling 'clear_codegen_session', which might have overlapping functionality, leaving some ambiguity in differentiation.

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 provides no guidance on when to use this tool versus alternatives, such as 'clear_codegen_session' or 'get_codegen_session'. It lacks context on prerequisites (e.g., needing an active session) or exclusions, leaving the agent to infer usage from the tool name alone.

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