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

Annotations already declare readOnly=true, idempotent=true, destructive=false, so the safety profile is covered. The description adds that output is severity-ranked findings with remediation, which is useful. But it never explains the gateMode semantics (warn vs block vs off), which is the one behaviorally significant aspect of this tool.

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 zero padding; purpose and placement in the workflow are front-loaded.

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?

An output schema exists, so return values need no explanation, and annotations cover safety. But with 0% schema coverage and a deep nested parameter object, an agent cannot tell what inputs to supply or how gateMode changes behavior. The description is complete on purpose but incomplete on invocation.

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 description mentions no parameter at all. Three parameters, one of which is a large nested boardData object with ~35 fields, are left entirely undocumented. gateMode's warn/block/off values in particular have behavioral meaning that the description should explain but does not.

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 (run) and resource (fabrication/assembly/testability production review rules) with scope clarified as PCB handoff, and the DFM/DFA/DFT framing plus 'before Gerber export' distinguishes it from easyeda_drc_run and easyeda_pcb_constraint_check. It stops short of naming those siblings explicitly, so a 4 rather than 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?

Clearly places the tool in the workflow: 'before Gerber export or manufacturing submission.' That is real when-to-use context. However, it never names the alternative checks (DRC, constraint check) an agent should skip in favor of this one, so it lacks exclusions.

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