12 skills · built from real production

The skills used to build a real CRM, packaged so you can drop them into your Claude.

Twelve Claude Code skills covering the full arc: anchor the build, ship the slice, catch the bugs, maintain the app. Every pattern is production-tested. The fastest install is one prompt pasted into your Claude Code — your Claude writes every SKILL.md straight into ~/.claude/skills/.

The Pack

12 skills, grouped by when you'd use them.

Click any card to read the full SKILL.md — the same file Claude reads when the skill fires. Hit the download icon to save just that one.

Phase 1

Anchor the build — before you write a line of code

Stop building for nobody.
Phase 2

Build the slice — actually ship code

Three big bodies of knowledge.
Phase 3

Ship safely — catch bugs before customers do

The avengers cycle.
Phase 4

Keep the app alive — maintenance & memory

Don't let it rot.
⌥ Claude + ◯ Codex (GPT)

How OpenAI's Codex got wired into the Claude Code workflow.

Claude is sharp, but Claude reviewing Claude misses bugs because they share blind spots. The fix: a different model with different training reviewing every commit. Different priors, different misses. Codex catches the bugs Claude would have happily shipped — cursor lies, NaN propagation, lifecycle races, architectural traps. Real findings, every commit.

The billing split that matters: Codex runs against a ChatGPT Plus subscription, NOT the Anthropic API. The two are completely separate. When Anthropic's 5-hour cap hits, Codex still works. When OpenAI rate-limits, Claude still works. Two flat budgets that don't compete.

1
Install
Run /plugin install openai/codex-plugin-cc inside Claude Code. CLI lands at ~/.local/bin/codex.
2
Auth
Run codex login in terminal. Browser OAuth via ChatGPT Plus. Flat-rate quota, no per-token charge.
3
Review
Before every meaningful commit, Codex reviews the diff with a focused adversarial prompt.
4
Patch or roll back
Take the L's. Same finding 3× in a row = approach is wrong; roll back, don't patch.
# The adversarial review prompt — what actually works codex exec --skip-git-repo-check " Adversarial review of [uncommitted diff] in [repo]. Context: [one paragraph — what the change does, why]. Run `git diff` to see the change. Adversarially review: 1. [specific concern A] 2. [specific concern B] 3. Anything else I missed. Be terse, list concrete bugs only, max 200 words. If clean, say so in 1 line. "
Real bugs Codex caught in production:
  • Pagination cursor that would have silently infinite-looped on a /search endpoint — same cursor name behaves differently across endpoints of the same vendor
  • Number("$245.00") returning NaN, propagating through every $-stat downstream
  • Vercel after() lifecycle: .then() chains died when the serverless worker tore down
  • quote_complete-as-bot-state-proxy lie that fired wrong "Pause Amber" buttons
  • Cursor regression detection too narrow (single-ID check missed partial overlap)
  • An architectural risk caught at design time — would have prevented a cost-runaway incident
Install

One prompt, and your Claude installs everything.

Open a fresh Claude Code session on your Mac, paste the prompt below. Your Claude fetches all 12 SKILL.md files from this page's URL and writes them straight into ~/.claude/skills/. Done.

Paste into Claude Code
Install the Super Skill Pack into ~/.claude/skills/.

The pack is served at __BASE_URL__. Read the manifest at
__BASE_URL__/install-manifest.json — it lists 12 skills, each
with a slug and a path to its SKILL.md.

For each skill in the manifest:
  1. mkdir -p ~/.claude/skills/<slug>
  2. Fetch __BASE_URL__/<path> (the path field from the manifest)
  3. Save the response body as ~/.claude/skills/<slug>/SKILL.md

When done, list the 12 slugs you installed and tell me to start a
fresh Claude Code session so the skills load.
Prefer to install manually?

Download the zip, unzip wherever, then copy the folders. Same result, no prompt.

curl -O __BASE_URL__/skill-pack.zip unzip skill-pack.zip cp -r skills/* ~/.claude/skills/
After install, fire it up

Start a fresh Claude Code session, type Q-Explanation. The pack walks you through itself. The right skill auto-fires on natural phrases.

$ claude > Q-Explanation
Recommended add-on: install Codex CLI for adversarial review on every commit. Inside Claude Code run /plugin install openai/codex-plugin-cc then codex login in your terminal. Codex bills against a flat ChatGPT Plus subscription, so it never competes with your Anthropic budget. The Codex Gate skill walks the rest of the setup.
