error-handling is a skill for Claude Code from wasintoh/toh-framework. It costs 74 tokens per session (2,160 once invoked), scanned A, original, MIT.

An error-handling guide for coding agents that fixes common coding problems automatically or explains harder ones in plain language.

In plain words
What is it for?
It helps address missing imports, undefined variables, type mismatches, missing dependencies, missing files, syntax errors, and linting problems.
Why use it?
It keeps routine issues from interrupting the work and replaces confusing error messages and stack traces with clear next steps.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

error-handling 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 1mo 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.

🔧 Error Handling Skill

Purpose: Auto-fix errors silently, translate when necessary Version: 1.0.0 Author: Toh Framework Team

Overview

This skill enables AI to handle errors intelligently - fixing them silently when possible, and translating them to human-friendly language when user needs to know.

Core Principle

Error occurs
    ↓
Can AI fix it automatically?
    ├── YES → Fix silently, continue working
    └── NO → Translate to friendly language, explain what user needs to do

USER SHOULD NEVER SEE RAW ERROR MESSAGES


Error Handling Strategy

Level 1: Silent Auto-Fix (User sees nothing)

These errors should be fixed WITHOUT telling user:

Error Type Auto-Fix Strategy
Missing import Add the import
Undefined variable Check context, add definition
Type mismatch Fix the type
Missing dependency Install it
Syntax error Fix syntax
Missing file Create it
Linting errors Auto-format

User Experience:

User: "สร้างหน้า dashboard"
AI: (encounters import error, fixes it silently)
AI: "✅ สร้างหน้า dashboard เสร็จแล้วครับ!"
(User never knows there was an error)

Level 2: Silent Fix with Brief Mention

Fix automatically but mention briefly:

Error Type Action
Deprecated API Fix + mention "อัพเดทเป็น API ใหม่ให้แล้ว"
Security vulnerability Fix + mention "ปรับให้ปลอดภัยขึ้น"
Performance issue Fix + mention "optimize ให้แล้ว"

User Experience:

AI: "✅ สร้างหน้า dashboard เสร็จแล้วครับ!
    💡 ปรับ API เป็นเวอร์ชันใหม่ให้แล้ว (เร็วขึ้น 2x)"

Level 3: Friendly Translation (User needs to act)

When AI can't fix automatically:

Situation Friendly Message
Missing API key "ต้องใส่ API key ก่อนนะครับ ไปเอาได้ที่ [link]"
Network error "อินเทอร์เน็ตมีปัญหา ลองใหม่อีกครั้งนะครับ"
Permission denied "ไม่มีสิทธิ์เข้าถึง ลองเช็ค permission ดูครับ"
Database connection "เชื่อมต่อ database ไม่ได้ เช็ค .env ดูครับ"

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
