## What it does

The skill lays out a four-step loop. First you name the goal command whose exit code decides success: `npm test`, `npm run build`, `npm run lint`, `npx tsc --noEmit`, or all of them chained with `&&`. Then the agent runs it, reads the output, finds the root cause and makes the smallest possible fix. Back to the run step.

The loop rules are strict. Ten iterations maximum — after that the agent stops and reports what is blocking progress. It fixes one error at a time, never deletes tests, and never silences errors with `@ts-ignore`, `eslint-disable` or `any`. If the error count grows instead of shrinking, it stops and reassesses.

For Cursor the skill documents a hook in `.cursor/hooks.json`: a `stop` event runs `bash .cursor/scripts/check-tests.sh`, the script checks the exit code and returns a `followup_message` when tests still fail. The catch is speed. Slow suites make the loop crawl, so the author suggests `--bail` or `--fail-fast`. And the agent is persistent, not inventive: a fix that needs a design change still needs you.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash

```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill grinding-until-pass -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill grinding-until-pass -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install spencerpauly/awesome-cursor-skills grinding-until-pass
```

```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill grinding-until-pass -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/spencerpauly/awesome-cursor-skills/tree/HEAD/resources/grinding-until-pass/SKILL.md

## When to use it
- clear failing tests after a large refactor
- fix type errors introduced by a dependency upgrade
- repair the build after merging a branch with conflicts
- clean up lint violations without disabling rules
- get `tsc` type-checking to a clean run

## Example prompts
- run `npm test` and keep fixing the code until every test passes
- loop on `npm run lint && npx tsc --noEmit && npm test && npm run build` until it's all green
- after the refactor, make `npx vitest run` pass without errors

# Grind Until Pass

Use this skill when you want the agent to keep working autonomously until a specific goal is met — all tests pass, the build succeeds, or linting is clean. Instead of stopping after one attempt, the agent loops until done.

## Steps

1. **Define the goal command** — the command whose exit code determines success:

   - Tests: `npm test` or `npx vitest run`
   - Build: `npm run build`
   - Lint: `npm run lint`
   - Type-check: `npx tsc --noEmit`
   - All of the above: `npm run lint && npx tsc --noEmit && npm test && npm run build`

2. **Run the command** — execute it and capture the output.

3. **If it fails — analyze and fix**:
   - Read the error output carefully.
   - Identify the root cause: failing test assertion, type error, lint violation, import error, etc.
   - Make the minimal fix. Don't refactor — just fix the error.
   - Go back to step 2.

4. **If it passes — stop and report**:
   - Report what was fixed and how many iterations it took.
   - Summarize the changes made.

## Rules for the Loop

- **Maximum 10 iterations** — if after 10 attempts the command still fails, stop and report what's blocking progress. Something fundamental is wrong and needs human input.
- **Fix one thing at a time** — don't try to fix all errors at once. Fix the first error, re-run, and see if the fix resolves downstream errors too.
- **Don't delete tests** — if a test is failing, fix the code to make it pass. Don't modify the test unless the test itself is clearly wrong (testing old behavior that was intentionally changed).
- **Don't suppress errors** — don't add `@ts-ignore`, `eslint-disable`, or `any` types to silence errors. Fix the actual problem.
- **Track progress** — if the number of errors is increasing instead of decreasing, stop and reassess the approach.

## When to Use This

- After a large refactor that broke multiple tests
- After upgrading a dependency that introduced type errors
- After merging a branch with conflicts that need resolution
- When you want to "just make it green" and trust the agent to grind through it
