Execute an auditioned client-owned extension

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

With no annotations, the description carries the full transparency burden and does disclose meaningful behavior: configuration and credentials stay local, and write methods require an exact one-call confirmation. It does not cover response behavior or failure modes, but the highest-risk aspects are communicated.

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?

Two sentences, front-loaded with the action and resource, followed by security and confirmation constraints. Every sentence adds value and there is no redundant or filler content.

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 tool with no annotations, low parameter coverage, and no output schema, the description provides a solid starting point but omits return value semantics, error/confirmation failure behavior, and how the three execution channels are chosen or configured. It is adequate but leaves several gaps for the agent to resolve.

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 40%, so the description needed to compensate for methodId, extensionId, and arguments. It partially does by connecting 'one method from an owned Pack' to the ID parameters, and it reinforces writeConfirmation behavior, but it does not explain the shape or role of arguments or how the execution channel is selected.

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 concrete action ('Execute one method from an owned Pack') and names three specific execution channels, making its purpose clear and distinct from broad pack-management tools. It does not explicitly contrast with run_ai_pack or run_ai_pack_audition, but the 'owned Pack' and 'client extension' scope provide enough differentiation.

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 when the user owns an auditioned Pack and wants to invoke one method through a configured execution environment. It also notes the write-confirmation precondition, but it does not explicitly state when to prefer this tool over alternatives or when not to use it.

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