launchdarkly-flag-create

Create and configure LaunchDarkly feature flags in a way that fits the existing codebase. Use when the user wants to create a new flag, wrap code in a flag, add a feature toggle, or set up an experiment. Guides exploration of existing patterns before creating.

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a well-structured workflow skill with clear sequencing and good validation steps, making it effective for guiding Claude through feature flag creation. Its main weaknesses are the lack of concrete code examples or MCP tool invocation examples in the body itself (deferring too much to reference files that may not exist), and some redundancy in safety guidance. The decision table and update instructions table are strong actionable elements.

Suggestions

Add at least one concrete MCP tool invocation example showing create-flag with actual parameters (project key, flag key, variations) so Claude has a copy-paste-ready template.

Include a brief inline code example in Step 4 for at least one common SDK (e.g., Node.js boolean variation) rather than deferring entirely to reference files, especially since bundle files aren't confirmed to exist.

Remove duplicated guidance about default values being the 'safety net'—it appears in Step 4, Step 5, and Important Context. Consolidate to one location.

DimensionReasoningScore

Conciseness

The skill is generally well-structured but includes some unnecessary explanation that Claude would already know (e.g., explaining what default values are for, explaining that flag keys are immutable in multiple places). The introductory paragraph restates what the skill description already covers. Some sections like 'Important Context' repeat guidance already given in the workflow steps (e.g., default value safety is mentioned in both Step 4 and Important Context).

2 / 3

Actionability

The skill provides clear procedural guidance and specific MCP tool names, but lacks executable code examples directly in the body—instead deferring to reference files for SDK evaluation patterns. The decision table for flag types is concrete and useful, and the update-flag-settings instruction format is specific. However, no actual MCP tool invocation examples (with parameters) are shown, and no code snippets demonstrate flag evaluation despite Step 4 being about adding code.

2 / 3

Workflow Clarity

The 5-step workflow is clearly sequenced with logical progression: explore → decide → create → implement → verify. Step 5 includes explicit validation checkpoints (compilation, flag existence verification via get-flag, both code paths, safe defaults). The workflow includes appropriate feedback loops and the separation between creation and targeting is clearly called out as a safety boundary.

3 / 3

Progressive Disclosure

The skill references two supporting files (references/flag-types.md and references/sdk-evaluation-patterns.md) and a sibling skill (launchdarkly-flag-targeting), which is good structure. However, no bundle files were provided, so we cannot verify these references exist. The main body is somewhat long (~120 lines of content) and the 'Updating Flag Settings' section could potentially be a separate reference, but it's reasonably sized. References are clearly signaled and one level deep.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is a strong skill description that clearly identifies the tool (LaunchDarkly), lists specific actions (create flags, wrap code, set up experiments), and provides explicit 'Use when' triggers with natural language terms. The description is concise, uses third person voice, and is highly distinguishable from other skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions: 'Create and configure LaunchDarkly feature flags', 'wrap code in a flag', 'add a feature toggle', 'set up an experiment', and 'guides exploration of existing patterns'. These are specific, actionable capabilities.

3 / 3

Completeness

Clearly answers both what ('Create and configure LaunchDarkly feature flags in a way that fits the existing codebase') and when ('Use when the user wants to create a new flag, wrap code in a flag, add a feature toggle, or set up an experiment') with explicit trigger guidance.

3 / 3

Trigger Term Quality

Includes strong natural trigger terms users would say: 'feature flag', 'flag', 'feature toggle', 'experiment', 'LaunchDarkly', 'create a new flag', 'wrap code in a flag'. Good coverage of synonyms and variations.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive due to the specific 'LaunchDarkly' domain and feature flag terminology. Unlikely to conflict with other skills since it targets a very specific tool and use case. The mention of fitting existing codebase patterns further narrows scope.
