Behavior4/5

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

The description discloses that deletion is permanent and that the operation is blocked in read-only mode, adding context beyond the annotations' destructiveHint and readOnlyHint. This clarifies irreversibility and an operational restriction not fully captured by the structured metadata.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with the core action in the first sentence and an important caveat in the second. Every word earns its place, 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.

Completeness5/5

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 an output schema available, the description covers the essential behavior, the condition under which it is blocked, and the parameter type. It is sufficiently complete for an agent to select and invoke the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter is fully described in the schema ('Numeric template ID or alias'), and the description also mentions ID or alias. Since schema coverage is 100%, the description adds no extra semantic meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description starts with 'Permanently delete a template by ID or alias,' clearly identifying the action (permanently delete) and resource (template). This distinguishes it from siblings like create_template, edit_template, and get_template.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides an explicit exclusion: 'BLOCKED in read-only mode,' which tells the agent when not to use it. However, it does not name alternative tools for non-permanent changes, so it stops short of full when/when-not guidance.

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