regenerate_bd_layout

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

No annotations, so the description carries the burden. It does disclose a meaningful trait: the operation is cosmetic and only rearranges layout, not design logic — valuable for judging side effects. However it says nothing about prerequisites (open block design), failure behavior, or whether it mutates the saved file.

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 short sentence, front-loaded with the action and resource, with the clarifying parenthetical placed after. Nothing redundant or padded.

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?

For a zero-parameter, no-output tool, the description covers what it does, that it is cosmetic, and when it is worth calling. The only omission is the implicit precondition of an open/active block design, which the surrounding session tools make inferable.

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?

The tool takes zero parameters, so there is nothing for the description to explain; the baseline of 4 applies. No parameter-related gaps exist.

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 ('Regenerate the block design layout') and adds qualifiers ('cosmetic') that separate it from functional BD siblings like create_block_design or save_bd_design. It doesn't name a sibling explicitly, so differentiation is implicit rather than explicit.

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?

'Useful before save' gives a concrete trigger and implicitly points at save_bd_design as the next step. It also flags the operation as cosmetic, telling the agent it is optional rather than required. It stops short of stating exclusions or prerequisites (e.g., an open BD is needed).

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