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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false, so the safety profile is covered. The description contributes the return payload contract (what fields come back), which matters because there is no output schema, but it omits that a call can come back with status "running" and must be followed via get_board_job, and gives no sense of response size.

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?

It is a single run-on sentence that is a field inventory rather than a front-loaded statement of purpose; every item arguably earns its place given no output schema, but the lack of lead verb and the list-heavy structure make it harder to scan than it needs to be.

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?

Because there is no output schema, the description rightly spells out the returned contents, which is the main completeness win. It still leaves gaps: no indication of cost/size of an all-footprints dump, no guidance to use refs/include_footprints to trim the response, and no mention of the asynchronous running-status path.

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 100%, so refs, wait_s, design_id and include_footprints are already documented, and the schema's wait_s text carries the job-polling semantics. The description adds nothing parameter-level, such as that refs narrows the footprint list or that the full unfiltered dump can be large; 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 resource is unmistakable: a full read-out of board state (layers, outline, rules, net classes, counts, footprints). However, it never names a verb and gives no differentiation from closely related siblings like get_board_context, board_census, or get_board_status, so an agent cannot tell from the description alone which snapshot tool to pick.

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 when-to-use guidance, no prerequisites, and no named alternative. The reader must infer from the sibling list whether this is the right inspector or whether board_census / get_board_context is cheaper for a narrower question.

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