End Edit Session

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

Annotations already declare destructiveHint=true and idempotentHint=true. The description adds valuable context: sessions are in-memory only, discarded on server restart, and calling the tool frees memory sooner. No contradictions found.

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?

Three sentences, all essential. Front-loaded with the main action, then adds usage context and benefits. No filler or 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?

Given the simplicity (1 param, high schema coverage, output schema exists), the description covers purpose, usage, and side effects. Could mention what happens if session_id is invalid, but the idempotentHint implies safe handling.

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 coverage is 100%. The parameter 'session_id' is well-documented in the schema with minLength and description. The tool description does not add further parameter details, which is acceptable given the schema coverage.

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?

Clearly states the tool ends an iterative-edit session and distinguishes from siblings like start_edit_session by noting it is optional cleanup. The verb 'Free' and resource 'iterative-edit session' are specific.

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?

Explicitly states when to use (to free memory sooner, keep list tidy) and when not to use (safe to skip because sessions are discarded on restart). Provides alternative: not calling the tool.

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