✓ Confirm a pending action

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

The description adds valuable context beyond annotations, such as single-use nature, soft-confirmation mode, and the role of the env variable. It explains the behavioral intent and guard mechanisms.

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 efficient and front-loaded, though somewhat dense. It conveys necessary information in two sentences, but could be slightly more structured for readability.

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 lacks details about the return value or error conditions, which is important since there is no output schema. It does not fully explain what to expect after a successful confirmation.

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 description reiterates the parameter purpose but adds context about the confirmation_secret and soft-confirmation mode. Since schema coverage is 100%, baseline is 3; the additional context raises it to 4.

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 tool executes a previously deferred action by its confirmation_id, distinguishing it from sibling tools like meta_cancel_action and meta_list_pending_actions.

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?

Explicitly states to use only after explicit human confirmation, explains the two-step guard, and discusses the soft vs hard confirmation modes. Provides clear context on when and how to use.

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