Prepare a PCB design rule edit

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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description usefully confirms this is a non-mutating staging step that returns a target identity, baseline snapshot, editId and confirmation string — exactly the context an agent needs to know nothing is applied yet. It omits how long the editId remains valid, whether the baseline is captured server-side, and what happens on a stale edit, keeping it below 5.

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?

Two tightly written sentences with the purpose front-loaded and the return contract stated second; every phrase carries weight. It is arguably too terse for a schema this complex, but there is no filler to cut.

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?

Return-value expectations are adequately covered in prose despite no output schema, and the non-mutating nature is clear. However, for a tool with a five-branch union input and zero schema descriptions, the definition leaves the most complex part of the contract — the rule payloads and the confirm workflow — unexplained.

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 0% and the operation parameter is a five-variant oneOf (createConfiguration, updateCurrentConfiguration, replaceNetRules, replaceNetByNetRules, replaceRegionRules) whose 'config' and 'rules' payloads are untyped free-form objects. The description explains none of these variants, nor what shape config/rules must take, nor what timeoutMs affects, leaving the agent to guess at the core input contract.

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 precise verb+resource pair ('Prepare ... edit for native EasyEDA Pro PCB design rules') and the 'prepare' framing plus the returned editId/confirmation string clearly distinguish it from read-only siblings like easyeda_get_drc_rules or easyeda_get_drc_edit_result. It does not explicitly name an alternative tool, so it falls just short of a 5.

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?

Usage is only implied: the mention of a 'required confirmation string' hints at a two-step prepare-then-confirm workflow, but the description never states when to choose this over easyeda_get_drc_rules, nor does it name the follow-up tool (easyeda_confirmed_action) that consumes the editId. The agent must infer the sequence from the name alone.

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