search_passives

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

Discloses search scope (names and stat descriptions, case-insensitive) and error behavior. With no annotations, description carries the burden; it does well without needing to detail return values due to output schema.

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?

Concise: 5 lines, front-loaded with purpose. Every sentence adds value (scope, prerequisite, examples). No waste.

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 output schema exists, return details not needed. Description covers purpose, prerequisite, scope, case-insensitivity, and examples. Complements siblings like get_passives and search_tree.

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 single parameter 'query' is thoroughly described: it searches both names and stat descriptions, case-insensitive. Examples clarify usage. Schema coverage 0% but description compensates fully.

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 uses a specific verb+resource: 'Search the loaded build's allocated passives for nodes matching a keyword.' It clearly distinguishes from siblings like get_passives which likely returns all passives.

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 states prerequisite 'Requires tree data to be loaded; returns an error message otherwise.' Provides examples illustrating typical usage. Does not explicitly mention when not to use, but context is clear.

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