get_fixture_inventory

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

No annotations are provided, so the description carries full burden. It describes a read operation ('Get') but lacks details on permissions, rate limits, pagination, or response format. The description doesn't contradict annotations, but it's insufficient for a tool with no annotation coverage, missing key behavioral traits.

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?

The description is a single, efficient sentence that front-loads the core purpose without unnecessary words. Every part earns its place by specifying the action, resource, and scope concisely.

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 no annotations and no output schema, the description is incomplete. It doesn't explain what 'capabilities' entail, how results are structured, or any operational constraints. For a tool with three parameters and potential complexity in lighting systems, more context is needed to guide effective use.

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 description coverage is 100%, so the schema fully documents all three parameters. The description adds minimal value by hinting at 'project or globally' which relates to 'projectId', but doesn't provide additional syntax or meaning beyond what the schema already specifies. Baseline 3 is appropriate given high schema coverage.

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 clearly states the verb 'Get' and the resource 'available lighting fixtures and their capabilities', specifying scope with 'for a project or globally'. It distinguishes from siblings like 'get_project_details' or 'get_channel_map' by focusing on fixtures, but doesn't explicitly differentiate from 'analyze_fixture_capabilities' which might overlap.

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?

The description implies usage by mentioning 'for a project or globally', suggesting context for filtering, but doesn't provide explicit guidance on when to use this tool versus alternatives like 'analyze_fixture_capabilities' or 'get_project_details'. No exclusions or prerequisites are stated.

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