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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only states the action without revealing side effects, permissions, return behavior, or what happens to existing templates. The version note adds no behavioral context.

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 very concise with one sentence plus a version note, containing no fluff. However, it may be too terse; the version note 'v0.4.0 Unified Prompt Templates feature' is minimally useful but not wasteful.

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 tool has 7 parameters, no annotations, and an output schema, the description is too sparse to be contextually complete. It lacks guidance on when to use it, behavioral expectations, and any clarification beyond the schema.

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?

Schema description coverage is high (86%), so the schema already explains most parameters. The description adds no additional meaning about parameters, leaving it at the baseline score.

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 action 'Register a new custom prompt template' with a specific verb and resource. It distinguishes from sibling tools like get_prompt_template, list_prompt_templates, export_prompt_template, and import_template_from_url by focusing on creating a new template via registration.

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 usage for adding a new custom template, but provides no explicit guidance on when to use this tool versus alternatives like import_template_from_url. No exclusions or alternative scenarios are mentioned.

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