upgrade_to_premium

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

No annotations are provided, so the description bears full responsibility for disclosing behavioral traits. It mentions the action and result (adding Yahoo Finance and other premium outlets) but doesn't disclose side effects, reversibility, prerequisites, or any operational implications such as cost or impact on existing distribution settings. This is a significant gap for a mutation tool.

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 a single, concise sentence that front-loads the action. There is no redundancy or filler; every word contributes meaning, making it highly efficient.

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 simple mutating tool with one parameter and no output schema, the description adequately explains what the tool does and the resulting state. It could be slightly more complete by mentioning that the release must already exist or that this is a permanent change, but overall it provides enough context for an agent to understand the tool's function.

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 input schema already fully describes the sole parameter 'release_id' with a clear description. The description's mention of 'existing release' adds only a subtle prerequisite implication. With schema coverage at 100%, the baseline of 3 is appropriate; the description adds minimal extra meaning beyond the schema.

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 ('Upgrade') and the target resource ('an existing release to premium distribution'), including the specific outcome of adding 'Yahoo Finance and other premium outlets.' This distinguishes it from simple release operations, though it doesn't explicitly differentiate from the similarly named sibling tool 'add_distribution_upgrade.'

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 context (upgrading a release to premium) but provides no explicit guidance on when to choose this tool over alternatives like 'add_distribution_upgrade' or other distribution-related tools. There are no when/when-not criteria or exclusions mentioned.

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