The plugin includes 13 slash commands, 5 specialized agent personas, 28 domain skills, and two local MCP servers (qector-library with 8 tools and qector-bench with 29 tools), with strict mathematical verification and fail-closed design. The integration is available via GitHub and supports Windows, macOS, and Linux, requiring Python 3.10+ and qector-decoder-v3==1.0.0.", "body_md": "**Professional Claude Code & Claude Desktop Integration**\n\nQECTOR is a high-performance, strictly verified quantum error correction engineering and research environment built for `qector-decoder-v3`\n\n.

Displays native UI controls, documentation, and the QECTOR icon directly within Claude Desktop's **Settings → Connectors** menu.\n\n**Commands (13 Slash Commands)**\n\n-\n`/qec-desktop-connector`\n\n: Zero-friction Claude Desktop MCP configuration. -\n`/qec-setup`\n\n: Guided first-time setup and diagnostic audit. -\n`/qec-facts`\n\n: Quick reference for codes, decoders, and strict-math rules. -\n`/qec-theorem`\n\n: Formulations and proof obligations for Theorems 1-16. -\n`/qec-reproduce`\n\n: Reference manual Appendix D reproduction workflows. -\n`/qec-decode`\n\n: Single-shot syndrome decoding asserting parity. -\n`/qec-threshold-sweep`\n\n: LER sweeps with exact Wilson 95% confidence intervals. -\n`/qec-wilson`\n\n: Wilson 95% score interval calculator. -\n`/qec-dem`\n\n: Detector Error Models (DEM) and Stim circuit inspection. -\n`/qec-code-inspect`\n\n: Verify code parameters$[[n,k,d]]$ and check matrices. -\n`/qec-benchmark`\n\n: Decoder latency and throughput microbenchmarks. -\n`/qec-sinter`\n\n: Sinter task templates and benchmark configuration. -\n`/qec-validate-mcp`\n\n: Validate tool schemas, JSON-RPC transport, and health.\n\n**Agents (5 Specialized Personas)**\n\n`qec-researcher`\n\n: Academic research, paper reproduction, threshold sweeps.`qec-developer`\n\n: Code integration, API design, performance tuning.`qec-validator`\n\n: Formal verification, mathematical proof checking.`qec-sysadmin`\n\n: Operations, zero-egress monitoring, incident response.`qec-hardware-engineer`\n\n: Physical qubit characterization, cryogenic constraints.\n\n**Skills (28 Domain Primitives)**\nComprehensive instruction sets covering `qector-core`\n\n, `qector-architecture`\n\n, `qector-bp-osd`\n\n, `qector-codes-builder`\n\n, `qector-math-foundations`\n\n, `qector-orchestration`\n\n, `qector-sinter`\n\n, `qector-dem-pipeline`\n\n, and more.\n\n-\n**Mathematical Strictness**: Every single syndrome decoding must verify$H c \\equiv s \\pmod 2$ . Approximations are rejected. -\n**Zero-Egress Security**: Operations run 100% locally. The plugin never transmits QEC simulation telemetry to the cloud, protecting proprietary hardware IP. -\n**Fail-Closed Design**: Mismatched matrix dimensions, unrecognized code families, or invalid distance requests immediately raise deterministic errors rather than silently corrupting the quantum state. -\n**Statistical Rigor**: All LER threshold sweeps include exact Wilson 95% binomial score intervals.
