create_project_label

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

Annotations only include 'openWorldHint' (true), which suggests flexibility. The description lacks details on behavioral traits such as scoping to a project, authentication requirements, or idempotency. It does not clarify how the label is associated with a project, despite the tool name implying project context.

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 extremely concise—two sentences that front-load the action and intention with no extraneous words.

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 the tool has 3 parameters with defaults and an output schema (not shown), the description does not explain what the parameters do, what the label represents, or what the output contains. It leaves significant gaps for an agent to use correctly.

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 0%, yet the description provides no information about the parameters 'name', 'color', or 'description'. It fails to add meaning beyond the schema's raw types and defaults.

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 'Create a reusable project label', specifying the verb and resource. It further distinguishes from the sibling tool 'add_project_label' by instructing to use that tool for attaching.

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 explicitly tells when to use this tool (to create a label) and when to use the sibling 'add_project_label' (to attach). However, it does not address other related siblings like 'create_label'.

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