delete_memory_entry

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

No annotations are provided, so the description should fully describe behavior. It mentions the deletion action, role restriction, and returns (success, key, message), but does not disclose side effects, irreversibility, or required permissions beyond roles. The behavioral disclosure is insufficient.

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 relatively concise with distinct sections for description, args, and returns. However, the inclusion of a contradictory requirement statement reduces clarity. The structure is adequate but flawed.

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 0% schema coverage, the description should compensate with comprehensive details. It provides a basic purpose and role constraint, but misses usage guidance, example scenarios, and behavioral nuances. The error in parameter semantics further undermines 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 states that 'caller_agent_id' is required ('必須'), but the input schema shows it is optional (default: null) and only 'key' is required. This is a factual error that misleads the agent. With 0% schema coverage, the description should clarify parameters but instead provides incorrect information.

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 'Delete a memory entry.' and specifies the operation by key. Among memory-related siblings (e.g., get_memory_entry, list_memory_entries), this tool is uniquely identified as the deletion function. The role restriction ('only Owner and Admin can use') further clarifies scope.

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 the role restriction, which is helpful for authorization awareness. However, it does not compare this tool to similar deletion tools like 'delete_global_memory_entry' or provide context on when to use local vs global deletion. The guidance is partial.

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