# monitoring-terminal-errors

A skill that watches a running process — dev server, test runner, build — for crashes and stack traces, then opens the failing file and fixes it. Handy when the log is long and the error is buried.

## What it does

The skill runs a loop: find the terminal holding the target process, read its output, pull the file path and line number out of the stack trace, open that file and patch it. Then it re-reads the log to confirm the server came back — hot reload usually picks the change up. If errors remain, the loop starts again.

The workflow is written out step by step. First the agent scans terminal files for one running `npm run dev`, `pnpm dev` or `python manage.py runserver`. Then it looks for known patterns: stack traces in the form `at <function> (<file>:<line>:<col>)`, Node.js and Python errors, `Unhandled Runtime Error` from React and Next.js, `Failed to compile`, `[vite] Internal server error:`, `error TS\d+:`. From a match it extracts the path, the line and the message.

One hard stop: after five attempts without a fix the skill gives up and reports back to you. It also tells you to check `exit_code` in the terminal file footer — if it is there, the process died outright and needs a restart rather than a code change. Cascading errors are worth fixing at the root first; the rest often clear on their own.

## Install

### Claude Code (native platform)

```bash
npx skills add spencerpauly/awesome-cursor-skills --skill monitoring-terminal-errors -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill monitoring-terminal-errors -a codex
```

2. **Manually: put the files in place**

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill monitoring-terminal-errors -a cursor
```

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

```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill monitoring-terminal-errors -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/monitoring-terminal-errors/SKILL.md

## When to use it
- find the terminal running a crashed dev server among several
- pull the failing file and line out of a stack trace
- fix `Module not found` after a file moved
- debug an `Unhandled Runtime Error` in React or Next.js
- tell a dead process apart from an error hot reload can fix

## Example prompts
- check the dev server terminal and fix whatever it is throwing
- the server keeps crashing with a stack trace — find the file and patch it
- read the build log and clear the `Failed to compile` error

# Monitoring Terminal Errors

Continuously watch a running process (dev server, test runner, build) for errors and fix them as they appear.

## Workflow

### 1. Identify the Terminal

List terminal files and find the one running the target process:

```bash
head -n 10 <terminals_folder>/*.txt
```

Look for terminals running dev servers (`npm run dev`, `pnpm dev`, `python manage.py runserver`, etc.).

### 2. Read Terminal Output

Read the full terminal file content. Search for error patterns:

- **Stack traces**: `at <function> (<file>:<line>:<col>)`
- **Node.js**: `Error:`, `TypeError:`, `ReferenceError:`, `ENOENT`, `ECONNREFUSED`
- **Python**: `Traceback (most recent call last):` followed by `File "<path>", line <n>`
- **React/Next.js**: `Unhandled Runtime Error`, `Error: ...`, `Module not found`
- **Build errors**: `ERROR in`, `Failed to compile`, `SyntaxError`
- **Vite**: `[vite] Internal server error:`
- **TypeScript**: `error TS\d+:`

### 3. Extract the Source Location

From the stack trace, extract:
- File path
- Line number
- Error message

For Node.js: `at functionName (/path/to/file.ts:42:10)`
For Python: `File "/path/to/file.py", line 42, in function_name`

### 4. Navigate and Fix

1. Read the identified file around the error line
2. Understand the error (missing import, type mismatch, undefined variable, etc.)
3. Apply the fix
4. Re-read the terminal file to confirm the server recovered (hot reload should pick it up)

### 5. Loop

If the server is still showing errors after the fix, repeat from step 2. Stop when:
- The terminal shows a clean "compiled successfully" or equivalent
- No new errors appear in the output
- You've made 5 attempts without resolution (report to user)

## Tips

- Check for `exit_code` in the terminal file footer — if present, the process has crashed entirely and needs a restart
- Some errors cascade — fix the first/root error and the rest often disappear
