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

Annotations already flag destructiveHint=true and openWorldHint=true, but the description adds non-obvious behavior: the token is single-use and must never be replayed, and responses return results rather than approval handles/JSON/debug. It doesn't describe failure or partial-failure behavior.

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?

Three dense, front-loaded sentences with no filler; the precondition, token source, single-use constraint, and return shape are all stated compactly, though the telegraphic 'Replies: results, not approval handles/JSON/debug' phrasing is slightly terse.

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 destructive single-use confirmation tool with an output schema (so return values needn't be detailed), it covers the key precondition, token source, reuse hazard, and response nature. The unexplained connection_context and absent failure semantics are the remaining gaps.

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?

With 0% schema description coverage, the description must carry parameter meaning. It clarifies confirm_token's prefix and provenance (pd_confirm_* from the prepare tool) but leaves connection_context entirely unexplained, so the coverage gap is only partially filled.

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?

States a specific verb+resource ('pause product-family delivery') and ties it to the exact upstream token ('pd_confirm_* from products_delivery_pause_prepare'), which clearly separates it from the sibling prepare/deny tools.

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 names the precondition ('after user approval'), the token source tool, and the constraint ('Single-use; never replay'), so an agent knows both when to call it and the sequencing relative to products_delivery_pause_prepare.

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