Select an AI Pack intelligence checkpoint

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

With no annotations, the description carries the behavioral disclosure burden. It adds meaningful safety context ('selection never rewrites the seller Pack') and explains the effect of sequence 0, which is valuable. It does not mention permissions, reversibility, or effects on existing runs, but the non-rewriting guarantee is a significant disclosed trait.

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 two compact sentences with the primary action front-loaded. The second sentence adds only high-value information: the sequence-0 special case and the guarantee that the seller Pack is never rewritten. No wasted words.

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 mutation tool with no annotations and no output schema, the description leaves important gaps. The required confirmation parameter is not explained as a deliberate consent token, which is critical for safe autonomous invocation. Prerequisites such as Pack ownership are only implied, and the description does not say what happens after selection.

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 only 33%, and the description compensates partly by explaining the sequence parameter ('Use sequence 0 to return to the signed base Pack'). The productId is only minimally described in the schema, and the required confirmation parameter is given no semantic meaning anywhere.

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 first sentence clearly identifies the operation ('set this account's default hosted intelligence checkpoint') and the target resource ('an owned Pack'), distinguishing selection from creation, listing, or execution. It does not explicitly name a sibling alternative, but the verb and resource are specific enough to avoid confusion.

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 gives useful context, such as using sequence 0 to return to the signed base Pack, and implies this tool is for setting an account-level default. However, it never explicitly states when to use this tool over siblings like propose_ai_pack_growth, accept_ai_pack_growth, or run_ai_pack, nor does it provide exclusions.

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