begin_transaction

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

No annotations are provided, so the description carries the full burden. It states only what the tool creates, but does not disclose side effects (e.g., invalidating an existing transaction), state prerequisites, concurrency limitations, or what happens to prior snapshots. This leaves the agent without behavioral expectations.

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?

A single concise sentence that front-loads the verb and object, with no filler words or redundant information. Every word adds meaning.

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 tool belongs to a transaction workflow (siblings include preview/validate/commit/rollback) and has three parameters plus an output schema, yet the description provides no context about workflow ordering, required state, or parameter semantics. The agent is left with insufficient information to use it correctly.

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 schema has three optional parameters (path, notes, expected_sha256) with 0% description coverage, and the tool description does not explain their meaning or expected format. An agent cannot determine correct values or why they are needed.

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 'create' with a clear object 'transaction snapshot' and scopes it 'for a document or live session.' This clearly differentiates it from sibling tools like commit_transaction or rollback_transaction.

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 provides no guidance on when to start a transaction, how it relates to preview/validate/commit/rollback, or any preconditions. The phrase 'for a document or live session' hints at scope but does not explain when to use this tool versus alternatives.

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