QECTOR Claude Plugin

Official QECTOR quantum error correction engineering plugin for Claude Code and Claude Desktop. Grounded in the QECTOR Decoder v3 reference manual (DOI 10.5281/zenodo.21941046) and the live qector-decoder-v3==1.0.0 Rust/PyO3 wheel. Zero-egress local stdio architecture ensures that circuits, parity matrices, and syndromes never leave your machine.

7 Strict-Math Domain Skills

• qector-core: Verified platform facts, 8 library MCP tools, 5 stable decoders, API grounding to prevent hallucination.
• qector-math-foundations: Theorems 1–16 executable ground truth over GF(2), fail-closed syndrome checking (H c = s mod 2), Wilson 95% CIs.
• qector-developer: Python SDK best practices, parity-check matrix generation, Sinter/Stim adapters, CI/CD testing.
• qector-researcher: Literature review, threshold discovery, Monte Carlo noise simulation, reproducible JSON export.
• qector-hardware-engineer: Physical qubit mapping, heavy-hex/surface graph constraints, cryogenic error budgets.
• qector-educator: Tutorial generation, conceptual explainers, interactive decoding walkthroughs.
• qector-sysadmin: Environment health diagnostics, resource bounds enforcement (MAX_CHECKS, MAX_QUBITS), runtime hygiene.

5 Specialized Agents

• qec-developer.md: Code integration, API design, performance tuning.
• qec-researcher.md: Academic research, paper reproduction, threshold sweeps.
• qec-validator.md: Formal mathematical verification and proof checking.
• qec-sysadmin.md: Operations, monitoring, incident response.
• qec-hardware-engineer.md: Physical qubit characterization, cryogenic systems.

8 Verified MCP Server Tools

list_code_families, list_decoders, get_license_info, decode_syndrome, decode_single, threshold_sweep, build_code_from_matrix, compat_report.
