Begin project transaction

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

The description adds behavioral context beyond annotations: transaction is in-memory, document-scoped, snapshot-backed, and does not modify EasyEDA. Annotations show destructiveHint=false but description clarifies non-modification and scope.

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 sentences with no wasted words. First sentence states core action, second adds constraint, third clarifies non-modification. Front-loaded and efficient.

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?

While annotations and output schema exist, the description fails to document parameters. For a multi-parameter transaction tool, leaving parameters unexplained reduces completeness significantly.

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 coverage is 0% and the description does not explain any of the 4 parameters (projectId, label, ttlSeconds, maxOperations). The schema provides names and constraints but the description adds no semantic value.

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 action ('Open an in-memory, document-scoped transaction') and the resource ('snapshot-backed schematic writes'). It distinguishes from sibling tools like commit/rollback by noting only one active transaction per document.

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 before write operations by stating 'transaction for snapshot-backed schematic writes' and the constraint 'only one active transaction'. However, it does not explicitly mention when not to use it or name alternatives.

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