delete_actor

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

The description explicitly says 'sets entry to null in Actors.json', which reveals a key behavioral trait beyond the schema. However, with no annotations, other important behaviors (permissions, irreversibility, side effects) are missing. This partial transparency places it at a 3.

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?

One sentence that is front-loaded with the action and resource, followed by a clarifying parenthetical. No redundant or filler content; every word earns its place.

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?

For a single-parameter deletion tool with no output schema, the description adequately explains the action and its effect. It could mention error handling (e.g., if ID does not exist) or note that the entry is not removed from JSON, but for a simple tool it is nearly complete.

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 schema describes the 'id' parameter as 'Actor ID to delete', and the description merely repeats that it deletes by ID. Since schema coverage is 100%, the description adds no new parameter meaning beyond the schema baseline. Score 3 is appropriate.

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 'Delete an actor by ID' which provides a specific verb and resource, and the parenthetical clarifies the behavior (sets to null) distinguishing it from other actor operations like update_actor. The sibling list confirms there is a separate delete tool for other entities, so it is clear what this tool does.

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 guidance on when to use this tool versus alternatives (e.g., update_actor or other delete tools). The description does not mention prerequisites, such as the actor existing, or note that the deletion is not a full removal but a null set. The agent receives no context for decision-making.

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