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

The description adds valuable authorization context ('Ownership is enforced') beyond the annotations. The 'single memory' phrasing clarifies scope versus bulk operations. The annotations already cover destructiveness and idempotency, so the description appropriately focuses on the security dimension not captured in structured hints.

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?

Two sentences efficiently structured: first declares the operation, second states the security constraint. Zero wasted words; information density is high 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?

Given the simple 2-parameter schema, complete annotations (destructive/idempotent hints), and standard delete-by-ID pattern, the description provides sufficient context. No output schema exists, but explicit documentation of return values is unnecessary for a standard deletion operation.

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?

With 100% schema description coverage, the schema fully documents both parameters. The description reinforces that the operation is 'by ID' (mapping to memory_id) and mentions agent_id in the ownership context, but does not add semantic details like ID format constraints or whether agent_id is optional for certain contexts.

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 specific action (delete), resource (memory), and scoping constraint (single/by ID). It effectively distinguishes from siblings like delete_agent_data (bulk deletion) and delete_episode (different resource type) through the 'single memory' specificity.

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 notes that 'Ownership is enforced when agent_id is provided,' implying an authorization requirement, but lacks explicit guidance on when to use this tool versus alternatives like delete_agent_data or archive_episode. No prerequisites (e.g., memory existence) are mentioned.

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