## What it does

The skill sets an order for config work: read the current state, make the change, then verify. It starts with `get-ai-config-health`, which flags variations with no model, variations with neither instructions nor messages, tool references that point at nothing, and configs with no variations at all. Then `get-ai-config` returns the full picture: mode (agent or completion), variation models, current instructions, attached tools and parameters.

Config metadata goes through `update-ai-config`: name, description, tags, archiving. A variation is edited with `update-ai-config-variation` — swap the model via `modelConfigKey` and `modelName`, rewrite instructions or messages, tune parameters such as temperature and max_tokens, attach or detach tools. Deletion (`delete-ai-config`, `delete-ai-config-variation`) is irreversible and needs `confirm: true`.

You need the remotely hosted LaunchDarkly MCP server configured, otherwise the skill has nothing to call. When someone says remove, retire or decommission, the skill archives by default, since `archived: false` brings the config back. Permanent deletion waits for an explicit confirmation. It also tells the agent to change one thing at a time and not to touch a production config before testing in another variation.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install launchdarkly/ai-tooling configs-update
```

2. **Manually: put the files in place**
- File: `.github/skills/configs-update/SKILL.md`

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/launchdarkly/ai-tooling --path skills/agentcontrol/configs-update
```

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- switch the model on a config variation
- rewrite instructions or messages in a prompt
- tune temperature and max_tokens
- retire an unused config by archiving it
- spot variations with no model and broken tool references

## Example prompts
- check the config health and tell me what's broken
- switch the variation to a new model and verify it
- archive this config, we don't need it anymore

# Config Update & Lifecycle

You're using a skill that will guide you through updating, archiving, and deleting configs and their variations. Your job is to understand the current state of the config, make the changes, and verify the result.

## Prerequisites

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

**Required MCP tools:**
- `get-ai-config-health` -- assess config health before making changes (detects missing models, orphaned tools, empty configs)
- `get-ai-config` -- understand current state before making changes
- `update-ai-config` -- update config metadata (name, description, tags, archive)
- `update-ai-config-variation` -- update variation model, prompts, or parameters

**Optional MCP tools:**
- `delete-ai-config` -- permanently delete a config (irreversible)
- `delete-ai-config-variation` -- permanently delete a variation (irreversible)

## Core Principles

1. **Fetch Before Changing**: Always check the current state before modifying
2. **Verify After Changing**: Fetch the config again to confirm updates were applied
3. **Archive Before Deleting**: Archival is reversible; deletion is not

## Workflow

### Step 1: Assess Health and Understand Current State

Start with `get-ai-config-health` to get a structured health assessment. This detects:
- Variations with no model (show as "NO MODEL" in the UI)
- Variations with neither instructions nor messages
- Orphaned tool references (tools attached that don't exist in the project)
- Configs with no variations at all

The health verdict (`healthy`, `warning`, `unhealthy`) helps you prioritize what to fix.

Then use `get-ai-config` to review the full detail:
- Current mode (agent or completion)
- Existing variations and their models
- Current instructions or messages
- Attached tools and parameters

### Step 2: Make the Update

**Update config metadata** -- Use `update-ai-config`:
- Change name or description
- Add or replace tags
- Archive with `archived: true` (reversible)
```
