At a glance

A skill your agent uses when writing shell scripts, Python automation, or any unattended batch job.

  • Writing shell scripts
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Python automation
  • Any unattended batch job

What it does

Robust Error Handling In Scripts is an agent skill from aiming-lab/MetaClaw. Use this skill when writing shell scripts, Python automation, or any unattended batch job. Ensure failures are detected, logged, and handled — never silently ignored.

Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Shell scripting, Error handling and Background jobs. It works with Python. The repository describes itself as: 🦞 Just talk to your agent — it learns and EVOLVES 🧬. The licence is MIT.

When your agent uses it

  • Writing shell scripts
  • Python automation
  • Any unattended batch job

Example prompts

  • “/robust-error-handling-in-scripts”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 922caf3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are python and bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Robust Error Handling In Scripts loads about 225 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 16 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~225

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Robust Error Handling in Scripts

Shell scripts:

bash
set -euo pipefail  # Exit on error, undefined var, pipe failure
trap 'echo "Failed at line $LINENO"' ERR

Python scripts:

python
import logging, sys
logging.basicConfig(level=logging.INFO, format='%(asctime)s %(levelname)s %(message)s')
try:
    main()
except Exception as e:
    logging.exception("Unhandled error: %s", e)
    sys.exit(1)

Retry with backoff for transient network/API failures:

python
from tenacity import retry, stop_after_attempt, wait_exponential
@retry(stop=stop_after_attempt(3), wait=wait_exponential(min=2, max=10))
def call_api(): ...
