harden SKILL.md skillA

harden from quriosity-agent/qcut is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add quriosity-agent/qcut/harden@git:20260308.8b86d2e

Pins git:20260308.8b86d2e in mdr.lock. Pin the fingerprint instead.

Improve interface resilience through better error handling, i18n support, text overflow handling, and edge case management. Makes interfaces robust and production-ready.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

Strengthen interfaces against edge cases, errors, internationalization issues, and real-world usage scenarios that break idealized designs.

## Assess Hardening Needs

Identify weaknesses and edge cases:

1. **Test with extreme inputs**:
   - Very long text (names, descriptions, titles)
   - Very short text (empty, single character)
   - Special characters (emoji, RTL text, accents)
   - Large numbers (millions, billions)
   - Many items (1000+ list items, 50+ options)
   - No data (empty states)

2. **Test error scenarios**:
   - Network failures (offline, slow, timeout)
   - API errors (400, 401, 403, 404, 500)
   - Validation errors
   - Permission errors
   - Rate limiting
   - Concurrent operations

3. **Test internationalization**:
   - Long translations (German is often 30% longer than English)
   - RTL languages (Arabic, Hebrew)
   - Character sets (Chinese, Japanese, Korean, emoji)
   - Date/time formats
   - Number formats (1,000 vs 1.000)
   - Currency symbols

**CRITICAL**: Designs that only work with perfect data aren't production-ready. Harden against reality.

How to install

The exact contents, by fingerprint

mdr add quriosity-agent/qcut/harden@sha256:6114cdc92bd913a6

The line at the top of this page pins the label git:20260308.8b86d2e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
