list_circuit_blocks

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

No annotations are provided, so the description carries the full burden. It usefully discloses that the catalog is fixed at 10 pre-validated entries with no filtering or parameters, but says nothing about return shape, ordering, or whether the list can change between calls — a modest gap for a trivial read-only listing.

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 front-loaded sentence with no filler; the key fact (all 10 pre-validated blocks) is stated immediately and nothing else is needed.

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-param, annotation-free listing tool this covers the essentials, but with no output schema the agent still doesn't know what a returned CircuitBlock looks like or how to use it downstream. Adequate but with a clear gap.

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 the schema has nothing to document and the baseline of 4 applies. The description correctly implies a parameterless, unfiltered enumeration.

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 pairs a clear verb ('List') with a specific resource ('CircuitBlocks') and adds scope ('all 10 pre-validated... in the hardware DSL catalog'). It does not explicitly contrast itself with siblings like synthesize_circuit, but no confusion arises given the distinct name and catalog framing.

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, nor any prerequisites or exclusions. At best the 'pre-validated catalog' framing implies you'd call it to discover available blocks before synthesizing, but nothing is stated explicitly.

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