launchdarkly-flag-cleanup

Safely remove a feature flag from code while preserving production behavior. Use when the user wants to remove a flag from code, delete flag references, or create a PR that hardcodes the winning variation after a rollout is complete.

Content

77%

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

This is a strong, well-structured skill that provides a clear, safe workflow for feature flag removal with appropriate validation checkpoints and explicit safety gates. Its main strengths are the actionable decision tables, concrete code examples, and the requirement for user confirmation before destructive changes. Minor weaknesses include some verbosity in the introductory sections and the inability to verify referenced bundle files exist.

Suggestions

Trim the opening paragraph — Claude doesn't need to be told 'You're using a skill that will guide you through...' — jump straight to the prerequisites or workflow.

Consolidate 'Core Principles' and 'What NOT to Do' sections, which overlap significantly (e.g., both say don't refactor unrelated code, always query LD).

DimensionReasoningScore

Conciseness

The skill is mostly efficient but has some unnecessary verbosity. The opening paragraph explains what the skill does redundantly (the user already invoked it). Some sections like 'Core Principles' and 'What NOT to Do' overlap. However, the tables and structured content are well-organized and most content earns its place.

2 / 3

Actionability

The skill provides concrete, specific guidance throughout: exact MCP tool names, a decision table for determining forward values, a real TypeScript code example showing before/after transformation, explicit steps for each phase, and specific patterns to search for. The workflow is copy-paste actionable.

3 / 3

Workflow Clarity

The 7-step workflow is clearly sequenced with explicit validation checkpoints: Step 2 has a readiness check with clear verdicts (safe/caution/blocked), Step 4 requires explicit user confirmation before proceeding, and Step 7 includes verification (build, lint, tests, final reference search). The feedback loop for blocked/caution states is well-defined.

3 / 3

Progressive Disclosure

The skill references external files (references/pr-template.md, references/sdk-patterns.md, related skills) which is good structure, but no bundle files were provided to verify these exist. The main SKILL.md itself is fairly long (~150 lines of substantive content) and some sections like the edge cases table and 'After Cleanup' could potentially be in reference files. The references are one-level deep and clearly signaled, which is positive.

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 an excellent skill description that clearly communicates a specific, well-scoped capability. It uses third person voice, provides concrete actions, includes an explicit 'Use when' clause with natural trigger terms, and occupies a distinct niche that minimizes conflict risk with other skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'remove a feature flag from code', 'preserving production behavior', 'delete flag references', 'create a PR that hardcodes the winning variation'. These are clear, actionable capabilities.

3 / 3

Completeness

Clearly answers both 'what' (safely remove a feature flag while preserving production behavior) and 'when' (explicit 'Use when' clause covering removing flags, deleting references, or creating PRs after rollout completion).

3 / 3

Trigger Term Quality

Includes strong natural keywords users would say: 'feature flag', 'remove a flag', 'delete flag references', 'PR', 'hardcodes', 'winning variation', 'rollout'. These cover the natural vocabulary of developers working with feature flags.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive niche: feature flag removal is a very specific task unlikely to overlap with other skills. Terms like 'feature flag', 'winning variation', and 'rollout' create a clear, unique trigger profile.
