four-leaf-coach

An open-source Skill that turns Claude (or ChatGPT, Cursor, Codex, GitHub Copilot) into a job search and interview prep coach. It pulls real job postings, role-specific interview intelligence, rubric-scored feedback on practice answers, and resume scoring from the hosted Four-Leaf MCP, then walks the user through preparing for an actual interview.

Free to install and use, including scoring the answers you type. Voice mock interviews (spoken answers, adaptive follow-ups) and full AI resume tailoring live on four-leaf.ai; the Skill surfaces those as an upgrade path when they're the right next step.

What it does

Walks a user through prep for a specific role at a specific company. The Skill greets, asks what they're prepping for, and routes them into one of seven guided workflows. Every workflow pulls live data from the Four-Leaf MCP's fifteen tools (jobs and full postings, role intel, question bank, answer scoring, match scoring, comp research, application tracker) and adds the Skill's coaching on top.

You don't type these as commands. Say what you want in plain language and the coach routes to the right workflow:

  • Kickoff the coach reads your application tracker, figures out what you're prepping for, and routes you. Say "help me get ready for my job search" or "where am I with everything".
  • Find jobs natural-language search across 140,000+ active postings, then pull up a full posting and save it to your tracker. Say "find me remote senior data scientist roles".
  • Prep for a role interview pipeline, what to expect, how to win. Say "what's the interview like for a PM at Stripe".
  • Practice calibrated questions, then type your answer and get it scored 1-10 against the same five-dimension rubric the Four-Leaf practice page uses. Say "give me a few hard system design questions".
  • Analyze a JD scores a resume against a posting and points out gaps. Say "how does my resume stack up against this JD".
  • Negotiate and comp research real numbers from the MCP. Have an offer? It runs a full analysis (total comp, market percentile, red flags, a counter strategy with exact talking points). Just asking what a role pays? It returns a cited salary band from a live web search. Say "they made an offer, help me negotiate", "is this offer any good", or "what's a good salary for a backend engineer in Austin".
  • Interview strategy formats, AI interviewers, work trials, signal vs noise. Say "what are AI interviews actually like".

Install

Two steps. The Skill tells your AI tool how to coach. The hosted MCP gives the Skill live data.

Step 1: install the Skill
npx four-leaf-coach add

That's it. The CLI detects your tool (Claude Code, Cursor, Codex, or GitHub Copilot), asks for scope when it matters, and copies the right bundle into the right place. Useful flags:

  • --tool pick the tool yourself: claude-code, cursor, codex, or github-copilot
  • --scope Claude Code only; where to install
  • --dry-run show what it would do without writing anything
  • --yes skip confirmation prompts, --force overwrite an existing install
  • four-leaf-coach list show the supported tools and what's detected in the current directory

Cursor needs the Nightly channel with Settings, Rules, Agent Skills enabled. The other tools work out of the box.

Step 2: install the Four-Leaf MCP for live data

The Skill works in degraded mode (coaching only, no live job data) without the MCP. To get real job search, role intel, answer scoring, and resume scoring, install the hosted MCP:

# Claude Code, Claude Desktop, and any tool that uses claude-mcp config

claude mcp add --transport http four-leaf https://four-leaf.ai/api/mcp

The first tool call opens the browser for OAuth. A free Four-Leaf account works (3-day trial included, no credit card).

For Cursor, ChatGPT Desktop, and other MCP-aware tools, configure the same URL (https://four-leaf.ai/api/mcp) per that tool's MCP setup docs.

Step 3: use it

Once it's installed, just tell the coach what you need in plain language. Say something like "help me prep for a senior software engineer interview at Google" and it takes it from there. There are no subcommands to memorize; the coach routes based on what you ask. (In Claude Code you can also invoke it explicitly with /four-leaf-coach.)

Manual install

If you'd rather not run npx (air-gapped network, or you just want to see what lands where), clone and build the bundles yourself. This is exactly what npx four-leaf-coach add --tool automates.

git clone https://github.com/fourleafai/clover-public.git

cd clover-public npm run build

npm run build reads skills/four-leaf-coach/SKILL.md plus the adjacent references/ tree and writes a dist/ / directory for each supported tool. Then copy your tool's bundle into place:

ToolBuild outputCopy into place
Claude Code (global, all projects)dist/claude-code/cp -r dist/claude-code/.claude ~/
Claude Code (single project)dist/claude-code/cp -r dist/claude-code/.claude PROJECT/ (replace PROJECT with your project path)
Cursor (Nightly + Agent Skills enabled)dist/cursor/cp -r dist/cursor/.cursor PROJECT/
OpenAI Codex CLIdist/codex/cp -r dist/codex/AGENTS.md dist/codex/references PROJECT/, then run Codex from PROJECT
GitHub Copilotdist/github/cp -r dist/github/.github PROJECT/ (flattened single-file variant)

The GitHub Copilot bundle is a single flattened file (.github/copilot-instructions.md) because Copilot reads one instructions file and doesn't follow references. The build inlines the whole Skill for it. The other three tools follow file references, so they get the source tree as-is.

What's free vs paid

  • Free: the Skill itself, and thirteen of the fifteen MCP tools. That's jobs and full postings, role intel, the question bank, answer scoring, match scoring, comp research, and reading and writing your application tracker. Six of them carry a daily cap on a free account (job search 30/day; question generation, answer scoring, match scoring, and the two comp tools 20/day each, on separate counters). The rest are unmetered.
  • Paid on [four-leaf.ai](https://four-leaf.ai): two tools. Voice mock interviews with spoken answers and adaptive AI follow-ups, and full AI resume tailoring against a specific JD. A paid plan also lifts the daily caps above. Three options at four-leaf.ai/pricing. 3-day free trial (no card), $5 5-Day Pass, $20/mo Pro. All three give you the same features.

The Skill surfaces these when they're the right next step. It doesn't push.

FAQ

What is four-leaf-coach? An open-source Skill that turns Claude, Cursor, OpenAI Codex, or GitHub Copilot into a job-search and interview-prep coach. The Skill is a structured set of instructions plus reference files that your AI tool loads. It works with the hosted Four-Leaf MCP server for live data (real job postings, role-specific interview intelligence, answer scoring, resume scoring, your application tracker).

How is this different from just prompting Claude for interview prep? Generic prompts produce generic advice. four-leaf-coach calls real tools: search_jobs returns actual apply URLs from 140,000+ active postings and get_job expands one to the full text; match_score runs a real scoring algorithm against your resume; generate_practice_questions produces role-calibrated questions and score_answer grades what you type against a five-dimension rubric; save_application puts a role in your tracker. The Skill orchestrates the calls and coaches around them.

Do I need a Four-Leaf account? For the data tools (jobs, role intel, question bank, answer scoring, match scoring, comp research, application tracker) a free Four-Leaf account works. The 3-day trial requires no credit card. Voice mock interviews and full AI resume tailoring are paid features on four-leaf.ai. The Skill surfaces those as an upgrade path when relevant.

Does the MCP work with ChatGPT? Yes. The MCP is HTTP-based with OAuth, so any MCP-aware client connects: Claude Desktop, Claude Code, Cursor, ChatGPT Desktop (Plus + Dev mode), Cline, Continue, Windsurf. The Skill itself is a Claude / Cursor / Codex / Copilot primitive; ChatGPT doesn't yet have a comparable file-based Skill convention, but the underlying MCP tools work there.

Can I use the Skill without the MCP? Yes, in degraded mode. Without the MCP, the Skill still coaches with structured workflows for prep, practice, JD analysis, and negotiation, just without live job listings, rubric-scored answers, or real resume scoring. Install the MCP to unlock the live data path.

Is the question bank really open? The Skill, the per-tool dist pipeline, and the install CLI are MIT-licensed in this repo. The question bank itself lives behind the MCP today; the open-data play is on the roadmap.

What about Pi, Gemini CLI, OpenCode, Trae, Rovo Dev, Qoder? On the roadmap. The dist pipeline can target any AI tool with a documented Skill or instructions-file convention. PRs welcome.

  • Coverage for more tools as their Skill conventions stabilize: Pi, Gemini CLI, OpenCode, Trae, Rovo Dev, Qoder.

Done so far: per-tool dist/ bundles generated from a single source (npm run build), a flattened single-file variant for GitHub Copilot, and the npx four-leaf-coach add one-command installer.
