8.0/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 5/5.

How do I install ChatCrystal Debug Recall?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use ChatCrystal Debug Recall with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 8.0/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 50a17e6

Real dependency, honestly disclosed: with no ChatCrystal Core/MCP server running (the normal state for a fresh install), the skill correctly refuses to invent a 'we've seen this before' answer and just adds one disclaimer line to an otherwise identical diagnosis — real recall value only appears after separately installing and running the companion ChatCrystal Core app (`npm install -g chatcrystal && crystal serve -d`).

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What ChatCrystal Debug Recall does

Recalls prior root causes, fixes, and pitfalls from ChatCrystal Core's local memory graph when working a failing test, exception, dependency break, or performance regression. Triggers on explicit debugging language and cleanly degrades to normal, non-fabricating debugging when the ChatCrystal Core MCP server isn't running.
