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

Annotations already indicate the tool is not read-only, so the mutation implied by 'append' is consistent. The description adds context about normalization options and a deterministic growth gate, but does not disclose what happens on gate failure or side effects beyond appending to the owner.

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, dense sentence that front-loads the purpose and then lists the steps. It is concise and avoids redundancy, though the jargon may reduce clarity for an uninitiated agent.

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?

The description omits critical domain context: what a 'delta' is, what the 'growth gate' entails, the meaning of the confirmation constant, and the role of sequence. With no output schema and minimal annotations, an agent lacks enough information to call this correctly without external knowledge.

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 coverage is only 25% (only productId has a description). The description hints at the normalization parameter ('Tetrees Agent or provider-free portable normalization') but does not explain sequence, confirmation, or normalization defaults. It does not compensate sufficiently for the low schema coverage.

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 identifies the action (accept growth) and the resource (AI Pack) with a specific process: normalize, run gate, append. It distinguishes from sibling tools like propose_ai_pack_growth and select_ai_pack_growth_version by implying it is the final acceptance step, though it does not explicitly name these alternatives.

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 explicit guidance on when to use this tool versus propose_ai_pack_growth or select_ai_pack_growth_version. The phrase 'append it to this owner only' hints at a finalization step, but there is no clear workflow context or exclusions provided.

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