Prepare Schematic-PCB Synchronization

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

Adds genuine value beyond the annotations: it explains that despite being a mutation-preparation tool, nothing is written until confirmed via easyeda_confirmed_action, which reconciles the readOnlyHint=true annotation that would otherwise look suspicious. It also discloses that a confirmation phrase is required and that discrepancies are previewed. It stops short of describing what the preview contains or what happens if the confirmation phrase does not match.

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 front-loaded sentence that packs purpose, the three action names, the preview behavior, and the confirmation gate with no filler. It is dense and somewhat compressed, but every clause carries information the agent needs.

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?

No output schema exists, so the description should carry more of the return-value burden, yet it only gestures at a 'cross-domain discrepancy preview' without saying what that preview reports. For an 8-parameter, mutation-adjacent tool with nested target objects and freshness fields, the gap around target/fingerprint semantics and confirmation failure is a real omission.

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 description coverage is high (88%), so width, height, layerCount, boardName, and the action enum are already documented in the schema and the baseline is 3. The description adds no per-parameter meaning and notably does not explain the schematicTarget/pcbTarget nested objects, whose capturedAt and fingerprint fields imply staleness validation the description never mentions.

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 and resource ('Prepares a synchronization or board creation mutation between Schematic and PCB') and enumerates the exact action enum values, so the agent knows precisely which operations route here. It distinguishes itself from the follow-up tool easyeda_confirmed_action, but does not differentiate from the sibling easyeda_compare_schematic_pcb, which also produces cross-domain discrepancy information.

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?

Clear workflow context: this is the prepare half of a two-step flow that only writes after easyeda_confirmed_action, which tells the agent when to use it in sequence. It lacks explicit exclusions (e.g., 'if you only want a read-only comparison without intent to mutate, use easyeda_compare_schematic_pcb instead') and says nothing about failure or mismatch handling.

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