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

No annotations are provided, so the description must disclose behavior, but it only mentions that distances are in millimetres. It doesn't explain whether operations are validated, whether they apply immediately or only after commit, what happens if the transaction doesn't exist, or any side effects. The term 'registered' is undefined.

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 sentences, front-loaded with purpose and a units caveat. It is efficient and avoids repetition, though it could include more behavioral context without bloating.

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?

Given the tool's complexity (many operation kinds, transaction lifecycle, no annotations), the description is too sparse. It fails to explain the batch semantics, the relationship to transaction lifecycle, validation behavior, or return value, despite having an output schema. This leaves significant gaps for an agent.

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 adds one useful parameter-level detail (millimetres) but doesn't explain the txid or the operations array structure. The schema provides the enum for 'kind' and the required fields, but the description does not clarify how to specify operation payloads or how they relate to the transaction. With 0% schema description coverage, this is insufficient.

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 uses a specific verb ('attach') and resource ('registered semantic operations' to 'existing transaction'), clearly indicating it stages operations for a transaction rather than executing them directly. It distinguishes from sibling tools like begin_transaction, commit_transaction, and individual operation tools, though it doesn't explicitly name them.

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 the transaction must already exist, giving some usage context, but it doesn't explicitly state when to use this vs calling individual operation tools or when in the transaction lifecycle it should occur. No exclusions or alternatives are mentioned.

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