Core domain knowledge and verified facts for the QECTOR quantum error correction platform. Covers the supported app-free qector-decoder-v3 library MCP server first, plus the optional QECTOR Workbench MCP server. Load whenever a request involves quantum error correction, decoders, code families, thresholds, syndromes, benchmarking, or the QECTOR MCP tool surface. Enforces the strict-math ground-truth rules (skills/qector-math-foundations) and prevents API hallucination by grounding every tool name, decoder, and API signature in what was actually verified.

Ground every answer in the verified facts below. If a request references a tool, decoder, or API that is not listed here or in references/qector_verified_api.md, say "not verified in this package" rather than inventing behavior. All mathematical claims must satisfy the rules in skills/qector-math-foundations (strict ground truth).

What this skill does

Qector Core is a community-contributed Claude Code skill in the physics sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/qector-core/ and loads when your prompt matches the skill's trigger.
