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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description usefully adds the full scope of returned data, but says nothing about pagination, response size, or how the wait_s/running-job flow behaves beyond what the schema notes.

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 dense sentence that leads with the board snapshot and then enumerates contents; efficient with no filler. It is somewhat run-on as a comma-separated list, which slightly hurts readability but wastes no words.

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?

With no output schema, the description carries the burden of describing return values and does so thoroughly, including footprint attribute details. It leaves minor gaps around the asynchronous job model and result size, but the essential content an agent needs is present.

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 100%, so all four parameters (design_id, refs, wait_s, include_footprints) are already documented in the schema. The description's mention of 'every footprint' loosely relates to include_footprints/refs but adds no new parameter meaning, so baseline 3 applies.

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 enumerates exactly what board data is returned (copper layers, outline, design rules, net classes, counts, zones/keepouts, footprints with attributes), so an agent can infer this is a read tool for a full board snapshot. However it is a noun-phrase listing with no verb and no differentiation from siblings like board_census or get_board_context, which also return board 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?

There is no statement of when to use this tool versus alternatives such as board_census, get_board_context, or get_board_status, and no preconditions or exclusions. Usage must be entirely inferred from the field list.

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