memory_session_end

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

No annotations are available, so the description must fully disclose behavior. It only says 'store its summary' without explaining what 'store' entails (e.g., persistence, immutability, or whether it finalizes the session). No mention of side effects or required permissions.

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 an extremely concise single sentence that front-loads the action. Every word serves a purpose with no redundancy.

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?

Despite having an output schema, the description does not clarify return values or behavior. With 5 parameters (2 required) and no param descriptions, the description leaves many open questions about usage and effects, especially regarding the optional project and integer parameters.

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%, yet the description provides no explanation for any of the five parameters (session_id, summary, project, memories_created, memories_accessed). Only 'summary' is hinted at via 'store its summary', leaving the rest completely undocumented.

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 'End a session and store its summary' clearly specifies the verb 'end' and the resource 'session', along with an additional action 'store its summary'. It uniquely identifies the tool among siblings, especially distinguishing it from 'memory_session_start'.

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 explicit when-to-use or when-not-to-use guidance is provided. However, the context of sibling tools like 'memory_session_start' implies its usage for ending sessions. Lacks prerequisites or consequences.

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