## What it does

The skill accepts `/flag <query>`, `flag <query>` and phrasings like "find flag <query>". It searches with `list-flags`, then pulls details with `get-flag` and reports the key, name, environment state, off variation, fallthrough behavior and rule complexity. When several flags match, you get a disambiguation list instead of a guess.

It is read-only. Creating, toggling, updating or deleting flags is out of scope, and it will not hand you a "safe to remove" verdict. Ask about staleness or cleanup and the answer is the summary plus a pointer to the flag discovery or flag cleanup skills, which scan code references and dependencies. Worth knowing before you expect `/flag` to do the analysis for you.

The remotely hosted LaunchDarkly MCP server has to be configured, with `list-flags` and `get-flag` available; `get-flag-status-across-envs` and `get-flag-health` are optional. `production` is the default environment unless you name another one. No MCP server means nothing for the skill to call.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add launchdarkly/ai-tooling --skill launchdarkly-flag-command -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-command/SKILL.md

## When to use it
- find a flag by name fragment or key
- tell two similarly named flags apart
- check a flag's state in a given environment
- grab the direct LaunchDarkly URL for a flag
- see how complex a flag's rules and targeting are

## Example prompts
- /flag checkout-redesign
- find flag payment in staging
- show me the new-onboarding flag, project web

# LaunchDarkly Flag Command Router

You're using a skill that standardizes quick `/flag` requests. Your job is to parse the user intent, resolve the requested flag with minimal friction, return an actionable summary, and route to deeper workflows when needed.

## Scope Boundary

This skill is a **read-only lookup entrypoint**. It returns flag details and routes forward.

**Hard constraints — you MUST NOT:**

- Create, toggle, update, or delete flags
- Assess whether a flag is safe to remove, stale, or ready for cleanup
- Provide a "verdict", "safe to remove" conclusion, removal steps, or "before removing" advice
- Offer to archive or delete the flag

**When the user asks about removal or staleness**, your entire response for that part must be the flag summary table followed by this exact routing message (you may rephrase slightly but must keep the substance):

> This quick lookup can only show you the flag's current config. To assess whether it's safe to remove, you need the **flag discovery** or **flag cleanup** skill — they scan code references, check status across all environments, and analyze downstream dependencies.

That's it. No analysis. No bullet points. No verdict. The removal question is answered by the routing message, not by you.

## Prerequisites

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

**Required MCP tools:**
- `list-flags` — search and disambiguate flag candidates
- `get-flag` — fetch detailed configuration for a resolved flag

**Optional MCP tools:**
- `get-flag-status-across-envs` — compare lifecycle status across environments
- `get-flag-health` — quick health snapshot for a single flag

## Command Contract

Treat these forms as equivalent intents:

- `/flag <query>`
- `flag <query>`
- "find flag <query>"
- "show me <query> flag"

Use `production` as the default environment unless the user specifies another environment.

## Workflow

### Step 1: Parse and Normalize Input

1. Extract the query text after `/flag`.
2. If no query is provided, ask for one concise identifier (flag key, name fragment, or tag).
3. Capture optional hints from the request:
   - Environment (`staging`, `production`, etc.)
   - Project key
```
