list_constraints

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

No annotations provided, and description only states it lists constraint names. It does not disclose any behavioral traits such as read-only nature, performance, or data freshness. For a simple list operation, the lack of detail is acceptable but not exceptional.

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 sentences, no fluff, front-loaded with purpose. Every sentence is meaningful.

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?

Given zero parameters and no output schema, the description is nearly complete. It could briefly mention that output is a list of constraint names, but the context of being used before get_constraint_loading implies the return format. Minor gap: no explicit output description.

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?

Input schema has zero parameters (100% coverage). According to guidelines, baseline is 4 for 0 parameters. Description adds no parameter info as none exist, which is appropriate.

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?

Description clearly states verb 'List', resource 'ERCOT transmission constraint names', and purpose 'to find constraint names before calling get_constraint_loading'. It distinguishes from sibling tool get_constraint_loading by indicating this is a preparatory step.

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?

Explicitly tells when to use this tool: 'Use this to find constraint names before calling get_constraint_loading.' This provides clear context and alternative/next-step tool reference.

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