create_release_label

Create a release label with a unique name, optional color, and sort order for categorizing releases in the workspace palette.

Instructions

Create a release label in the workspace palette. Name must be unique.

This defines a label; attach it to a release with manage_release_labels.

Args: name: Label name color: Hex color, e.g. "#4E5355" sort_order: Position in the palette

Returns: The created ReleaseLabel

A4.5/5.0

Behavior4/5

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

With no annotations, the description carries the transparency burden. It discloses the uniqueness constraint ('Name must be unique'), clarifies that it only defines the label and does not attach it to a release, and specifies the return value. This adds meaningful behavioral context beyond a simple 'create' action, though it does not address error handling or permissions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and well-structured: a one-line purpose, a uniqueness constraint, a clarifying note about attaching, and a clean Args/Returns format. Every sentence adds value, and it is front-loaded with the main purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple create tool with 3 parameters and a documented return, the description provides sufficient information. It also subtly distinguishes from related release label tools. It does not cover error conditions or permissions, but given the tool's simplicity and existing annotations absence, it is reasonably complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has no descriptions (0% coverage), so the description fully compensates by explaining each parameter: name is the label name (unique), color is a hex color with example, and sort_order is the position in the palette. This gives the agent clear semantic understanding that the schema lacks.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's action: 'Create a release label in the workspace palette.' It specifies the verb 'create', the resource 'release label', and the scope 'workspace palette', which distinguishes it from sibling tools like create_label or manage_release_labels.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context by noting that this defines a label and that attaching it to a release is done via manage_release_labels. This implies the use case (creating a label) and the follow-up action, but does not explicitly mention alternatives like create_label or when not to use this tool.

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