Generic AI vs. Jurisdiction-Aware Legal AI
Standard AI models default to US law and miss critical UK-specific statutes, thresholds, and procedures. This plugin ensures every response is grounded in England & Wales legislation with proper citations.
Without the Plugin
- ✗Defaults to US federal/state law terminology and concepts
- ✗Misses UK-specific thresholds (NLW £12.21/hr, ET 3-months-minus-one-day, SDLT bands)
- ✗No awareness of recent UK legislation (DMCC Act 2024, Renters' Rights Act 2025)
- ✗Generic disclaimers that don't meet SRA compliance standards
With the Plugin
- ✓Every response grounded in England & Wales statutes with section-level citations
- ✓Current rates, thresholds, and deadlines embedded (2025/26 tax year, April 2025 NLW)
- ✓Interactive calculators for SDLT, CT marginal relief, ET deadlines, auto-enrolment
- ✓SRA-compliant disclaimers on every response — legal information, not legal advice
15 Skills — Reference Areas & Workflow Tools
The plugin combines 11 deep reference skills covering English law practice areas with 4 structured workflow tools for common legal tasks — NDA screening, contract review, risk assessment, and UK GDPR compliance.
NDA Triage & Contract Review

Data Protection

Company Law
Directors' duties (ss.171-177 CA 2006), ECCTA 2023, small/micro-entity regimes, insolvency, and Companies House filing obligations.
Tax & HMRC

How the Plugin Works
The plugin uses structured workflow skills and deep reference knowledge to provide deep, practice-area-specific legal guidance. Each skill is a self-contained knowledge module covering one area of English law.
Jurisdiction Detection
Automatically identifies that your query relates to England & Wales law and applies the correct legal framework. Warns where Scottish or Northern Irish law differs.
Statute-Level Citations
Every response cites statutes by short title, year, and section number (e.g., Companies Act 2006, s.172). Recommends verification on legislation.gov.uk.
Interactive Calculators
Built-in calculators for SDLT, corporation tax marginal relief, Employment Tribunal time limits, auto-enrolment contributions, and more.
Current Rates & Thresholds
Embeds the latest 2025/26 rates — NLW £12.21/hr, CT 25%/19%, VAT registration £90k, CGT 18%/24%, IHT NRB £325k, and SDLT bands.
SRA-Compliant Disclaimers
Every response includes jurisdiction caveats, temporal validity warnings, and clear statements that output is legal information — not legal advice.
Case Law & Regulatory Guidance
References leading cases in ICLR neutral citation format and current regulatory guidance from ICO, FCA, CMA, SRA, and other UK regulators.

Frequently Asked Questions
No. This plugin provides legal information for England & Wales only. It does not constitute legal advice and is not a substitute for instruction of a qualified solicitor regulated by the SRA. Always verify critical matters with a legal professional.
England & Wales only. Scottish law (which has a separate legal system) and Northern Irish law are not covered. The plugin will warn you if a query may involve a different jurisdiction.

The content is identical — 15 skills (11 reference areas + 4 workflow tools) with the same depth and citations. The Claude Code version installs via CLI or plugin upload in the desktop app. The Claude Cowork (Dispatch) version uses the Cowork-compatible skill format for drag-and-drop installation.
The plugin reflects the position as at April 2025, including 2025/26 tax year rates, the National Living Wage of £12.21/hr, and recent legislation like the DMCC Act 2024 and Renters' Rights Act 2025. We recommend verifying critical figures on legislation.gov.uk and gov.uk.
The plugin can help you understand civil procedure (CPR 1998), court fees, track allocation, and Part 36 offers. However, it cannot file documents, represent you in court, or provide regulated legal advice. Always instruct a solicitor for litigation matters.
15 skills total: 4 workflow tools (NDA triage, contract review, legal risk assessment, UK GDPR compliance workflow) plus 11 reference areas (employment law, data protection, company law, intellectual property, property law, financial services & FCA, competition law, consumer law, litigation & civil procedure, tax law & HMRC, and UK regulatory bodies).
The plugin works standalone — describe your scenario or paste documents. For enhanced functionality, you can optionally connect MCP servers for Companies House API, HMRC MTD, Land Registry, legislation.gov.uk, and FCA Register.
Version 1.1.0 adds four structured workflow skills designed for common legal tasks UK SMBs face: (1) NDA Triage — screens NDAs as GREEN (safe), YELLOW (flag with solicitor), or RED (do not sign); (2) Contract Review — clause-by-clause playbook analysis with UK market norms; (3) Legal Risk Assessment — 5x5 severity/likelihood matrix with UK regulatory enforcement context; (4) Compliance Workflow — step-by-step UK GDPR/DPA 2018 procedures including DSARs, DPIAs, breach notification, and international transfers. These are workflow tools that help you prepare before going to a solicitor — not legal advice.
