Sloth-ninja lays the UK groundwork before touching JessicaOSS

This fork pauses feature work long enough to make the move from US-focused research tools deliberate and testable.

i18ninfrastructure

The proposed direction is clear: replace the current US legal-research assumptions with UK public sources, UK terminology and an option for locally run AI models. Sloth-ninja has left the consequential choices - database changes, provider settings and terminology - open for review.

  • Companies House support is designed, including rate limits and caching, but is not active yet.
  • legislation.gov.uk checks are live: invented statutory citations fail the quality gate.
  • Case-law citations still fail until the project has access to a licensed verification source.
  • Local-model support is planned around the interface those tools actually provide, rather than assuming they behave like OpenAI.

The team also added review guidance and safeguards around sensitive changes, while keeping unfinished evaluation cases visibly pending.

So what Legal teams considering a UK-oriented fork should care: this is early-stage work, but it shows a disciplined route to research features they can trust.

commit body 
- .claude/agents/frontend-designer.md (Sonnet): implements UI against the
  existing design system (shadcn/Tailwind patterns, event chips, side panels,
  en-GB formats) for the panels/pickers the UK integrations add
- .claude/agents/uk-copywriter.md (Sonnet): writes user-facing copy in UK
  English; mechanical terminology swaps allowed, legal terms of art always
  escalated for human sign-off
- pretool-guard: migrations writes now permitted only for basenames in the
  human-maintained .claude/hooks/authorized-migrations.json (which agents are
  blocked from editing); seeded with the two migrations authorised today
- MIGRATION_SPEC §6: record migration authorisation (6 July 2026)
