+}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark the tool destructive, but the description adds valuable context beyond that: content is erased, a tombstone remains, and only visible entries are affected. This meaningfully discloses soft-delete semantics and permission boundaries.
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 only one sentence but packs the core verb, permission scope, version requirement, and destructive effect. There is no filler or redundancy, and the most important information is front-loaded.
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 annotations, output schema, and detailed parameter descriptions, the description covers what is needed for a competent agent: deletion, destructive consequence, tombstone semantics, and version-based concurrency. It does not explain every edge case, but the schema and annotations fill the remaining gaps.
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 adds the 'using its version' condition, which maps to the expected_version parameter. It does not describe the id parameter, but the schema already provides meaningful documentation for both fields. The description provides some extra meaning without fully compensating for the incomplete 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?
The description states a specific action ('deletes a visible entry') plus version requirement, and clear effect ('content is erased and a tombstone remains'). This makes it easy to distinguish from sibling tools like delete_memory or restore_space_entry_version.
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 implies when to use it: author/owner deleting a visible entry with its version. But it does not explicitly name alternatives or exclusions, such as when to use delete_memory or restore_space_entry_version instead. The guidance is inferable but not explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
