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

Annotations already establish readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds real value on top by disclosing the result space (free, subscriber, lifetime, purchased, unauthorized), which is behavioral information the annotations do not carry and there is no output schema to supply it.

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?

A single compact sentence with the outcome enumeration front-loaded after the core question; nothing is padded. It is slightly clipped in phrasing ('take a component or template'), but every clause 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 one-parameter, read-only check with no output schema, the description supplies the essential missing piece: what the returned verdict values mean. The main residual gap is that it never indicates the calling context (check-before-download) or any auth requirements.

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?

With a single parameter at 100% schema description coverage, the schema already documents 'slug' as a component or template slug. The description adds no extra meaning about the parameter (e.g., whether template vs component slugs are both accepted, or format/casing), so the baseline of 3 applies.

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 check (can the caller take this asset) against a specific resource (component or template) and even enumerates the possible verdicts. It reads as an entitlement check rather than a fetch, which distinguishes it from siblings like get_component or get_template, though it never names those siblings explicitly.

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?

Usage is only implied: an agent can infer this should be called before attempting to take/download a paid asset, but the description never says when to call it, when not to, or how it relates to get_component/get_template. No alternatives or preconditions are named.

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