configs-variations

configs-variations is a skill for Claude Code, Codex from Bilal140202/the-lord-of-the-skills. It costs 33 tokens per session (1,243 once invoked), scanned A, original, MIT.

A workflow for creating and managing alternative AI configurations, including different models, prompts, and settings. It supports controlled experiments that change one factor at a time.

In plain words
What is it for?
Use it to copy a configuration with selected changes, review existing alternatives, refine unsuccessful ones, and measure which setup works best.
Why use it?
It removes guesswork when comparing AI setups by giving each change a clear test and a way to compare results. It requires the LaunchDarkly MCP server, which connects the coding agent to LaunchDarkly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

configs-variations scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Config Variations

You're using a skill that will guide you through testing and optimizing configs through variations. Your job is to design experiments, create variations, and systematically find what works best.

Prerequisites

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

Primary MCP tool:

  • clone-ai-config-variation -- clone a baseline variation with selective overrides (recommended for experimentation)

Alternative MCP tools (for more control):

  • get-ai-config -- review existing variations before adding new ones
  • create-ai-config-variation -- create new variations from scratch

Optional MCP tools:

  • update-ai-config-variation -- refine a variation after creation
  • delete-ai-config-variation -- remove variations that didn't work out

Core Principles

  1. Test One Thing at a Time: Change model OR prompt OR parameters, not all at once
  2. Have a Hypothesis: Know what you're trying to improve
  3. Measure Results: Use metrics to compare variations
  4. Verify via Tool: The agent fetches the config to confirm variations exist

Workflow

Step 1: Identify What to Optimize

What's the problem? Cost, quality, speed, accuracy? How will you measure success?

Step 2: Design the Experiment

Goal What to Vary
Reduce cost Cheaper model (e.g., gpt-4o-mini)
Improve quality Better model or more detailed prompt
Reduce latency Faster model, lower max_tokens
Increase accuracy Different model family (Claude vs GPT-4)

Step 3: Create Variations (Recommended: Clone with Overrides)

Use clone-ai-config-variation to duplicate the baseline and override only what you're testing. The tool reads the source variation, merges your overrides, and creates the new variation. Everything you don't pass is inherited from the source automatically.

Required fields:

  • sourceVariationKey -- the baseline to clone from
  • key and name -- identifiers for the new variation (e.g., gpt4o-mini-cost-test)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

configs-variations is a skill published in the GitHub repository Bilal140202/the-lord-of-the-skills (4 stars, last pushed 6d ago), licensed MIT. It adds 33 tokens to every session and 1,243 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
