## What it does

The skill audits LaunchDarkly feature flags using configured MCP tools. It requests the target `projectKey`, inspects critical environments like production, and groups flags by lifecycle state and type. You can run a full inventory scan or inspect a single toggle.

Operation depends entirely on a remotely hosted LaunchDarkly MCP server. Tools such as `list-flags`, `get-flag`, and `get-flag-status-across-envs` are required, while `find-stale-flags` and `check-removal-readiness` add depth. The tool checks for evaluation staleness, cross-environment discrepancies, and returns a verdict of `safe`, `caution`, or `blocked`.

This skill handles discovery and safety checks only. It does not touch your codebase to remove toggle references, nor does it alter targeting rules directly in LaunchDarkly.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill launchdarkly-flag-discovery -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/launchdarkly-flag-discovery/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/launchdarkly-flag-discovery/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill launchdarkly-flag-discovery -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/launchdarkly-flag-discovery/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill launchdarkly-flag-discovery -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/launchdarkly-flag-discovery/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install launchdarkly/ai-tooling launchdarkly-flag-discovery
```

2. **Manually: put the files in place**
- File: `.github/skills/launchdarkly-flag-discovery/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill launchdarkly-flag-discovery -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/launchdarkly/ai-tooling --path skills/feature-flags/launchdarkly-flag-discovery
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/launchdarkly-flag-discovery/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill launchdarkly-flag-discovery -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/launchdarkly/ai-tooling/tree/HEAD/skills/feature-flags/launchdarkly-flag-discovery/SKILL.md

## When to use it
- audit LaunchDarkly feature flag inventory across environments
- identify stale and abandoned temporary flags
- check flag removal readiness for blockers and warnings
- evaluate evaluation activity and targeting complexity

## Example prompts
- Audit all temporary flags in the core-app project
- Check if flag checkout-redesign is safe to remove
- Find stale LaunchDarkly flags inactive for more than 30 days

# LaunchDarkly Flag Discovery

You're using a skill that will guide you through auditing and understanding the feature flag landscape in a LaunchDarkly project. Your job is to explore the project, assess the health of its flags, identify what needs attention, and provide actionable recommendations.

## Prerequisites

This skill requires the remotely hosted LaunchDarkly MCP server to be configured in your environment.

**Required MCP tools:**
- `list-flags`: search and browse flags with filtering by state, type, tags
- `get-flag`: get full configuration for a single flag in a specific environment
- `get-flag-status-across-envs`: check a flag's lifecycle status across all environments

**Optional MCP tools (enhance depth):**
- `find-stale-flags`: find flags that are candidates for cleanup, sorted by staleness
- `get-flag-health`: get combined health view for a single flag (merges status + config)
- `check-removal-readiness`: detailed safety check for a specific flag

## Workflow

### Step 1: Understand the Project

Before diving into flag data, establish context:

1. **Identify the project.** Confirm the `projectKey` with the user. If they haven't specified one, ask.
2. **Understand scope.** Ask the user what they're trying to accomplish:
   - Broad audit? ("What's the state of our flags?")
   - Targeted investigation? ("Is this specific flag still needed?")
   - Cleanup planning? ("What flags can we remove?")

### Step 2: Explore the Flag Landscape

Adapt your approach to the user's goal:

**For a broad audit:**
- Use `list-flags` scoped to a critical environment (default to `production`).
- Note the total count: this tells you the scale of the flag surface area.
- Filter by `state` (active, inactive, launched, new) to segment the landscape.
- Filter by `type` (temporary vs permanent): temporary flags are the primary cleanup targets.

**For cleanup planning:**
- Use `find-stale-flags`: this is the most efficient entry point. It returns a prioritized list of cleanup candidates sorted by staleness, categorized as:
  - `never_requested`: created but never evaluated (possibly abandoned)
  - `inactive_30d`: no SDK evaluations in the specified period
  - `launched_no_changes`: fully rolled out, no recent changes
```
