create_configmap

Create Kubernetes ConfigMaps by specifying key-value pairs or providing a raw YAML manifest. Supports dry-run and multi-cluster targets.

Instructions

Creates a new ConfigMap. Use either basic key-value data or provide a raw YAML manifest.

A4.1/5.0

Behavior3/5

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

The description discloses the creation action and mentions the dryRun parameter for simulation, which adds some transparency. However, it does not detail error conditions, idempotency, or whether the ConfigMap is overwritten if it already exists. With no annotations, the burden is higher but partially met.

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 two sentences, directly stating the action and the two modes, with no unnecessary words. Every sentence adds value.

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

Completeness3/5

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

For a creation tool with 6 parameters and no output schema, the description adequately explains the two input methods but does not cover return values, error handling, or other behavioral details. It meets minimum viability but lacks richness.

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

Parameters4/5

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

Schema coverage is 100%, baseline 3. The description adds meaning by explaining the relationship between 'data' and 'yamlManifest' parameters ('basic key-value data or provide a raw YAML manifest'), which goes beyond the schema descriptions.

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 states 'Creates a new ConfigMap' with a specific verb and resource, and it differentiates from siblings like update_configmap and list_configmaps by focusing on creation. The two methods (key-value or YAML) add clarity.

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?

It provides clear context on two usage modes ('Use either basic key-value data or provide a raw YAML manifest'), but does not explicitly state when not to use this tool or compare to alternatives, which are limited given the sibling list.

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