monitoring-terminal-errors

monitoring-terminal-errors is a skill for Claude Code from spencerpauly/awesome-cursor-skills. It costs 35 tokens per session (561 once invoked), scanned A, original, CC0-1.0.

A method for watching a running development process for crashes, stack traces, and other errors, then tracing them to the relevant source file and line.

In plain words
What is it for?
Use it with development servers, test runners, or builds to identify error messages, find their source locations, diagnose the cause, and apply fixes.
Why use it?
It helps catch failures as they appear instead of requiring developers to repeatedly inspect terminal output and locate the cause manually.

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

monitoring-terminal-errors 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 10d 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.

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:

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
  • For HMR errors, the fix might just be saving the file again to trigger a rebuild
