Adds a boolean-search skill to litigation-legal. It helps litigation and arbitration attorneys build Boolean (i.e., terms-and-connectors) search strings for legal research databases. It constructs the strings from a research question and expanding the query terms (with attorney review built in via the alternatives ladder and term-selection checklist), by reverse-engineering a search from uploaded relevant cases, or by refining/porting an existing string.

Currently scoped to Westlaw and the arbitration databases (Jus Mundi, Kluwer, ITA); the arbitration capability could move to a dedicated arbitration-legal plugin in future. The same term-expansion method can be adapted for discovery/disclosure term drafting (e.g., an ESI protocol for an FRCP Rule 26(f) meet-and-confer), but that is currently explicitly out of scope.

Design notes:

  • Guardrails designed into the skill, without relying on CLAUDE.md (passes the Legal Skill Design Framework / skills-qa at READY).
  • Freshness fields declared for the bundled connector reference.
  • Ships qa.md with LLM-as-judge regression scenarios.

Build / reverse-engineer / refine / port Boolean / Terms-and-Connectors
search strings for legal research databases. Repointed from the experimental
arbitration-legal plugin to litigation-legal (config + matter paths, sibling
skills); retains the international-arbitration databases (Jus Mundi, Kluwer,
ITA Law) and treaty vocabulary. README registers the skill and notes a
possible future arbitration-legal plugin.
…ation DBs

- Carry guardrails in the skill itself rather than leaning on CLAUDE.md:
  jurisdiction-correct work-product header, uploaded-case injection defense,
  model-knowledge provenance on synonym sets and introduced authorities,
  verbatim-phrase rule, file-access-failure path.
- Scope to legal research; drop the e-discovery/destination-header conflation
  and note discovery term-drafting as out of scope.
- Remove Lexis (aligns with 210fd7a "Remove Lexis references at partner
  request"); target Westlaw + the arbitration specialists (Jus Mundi, Kluwer,
  ITA).
- Declare freshness fields for the bundled connector reference, verified
  against public Westlaw guides.
- Add qa.md (LLM-as-judge scenarios); humanize the README entries.
- Bump litigation-legal 1.0.2 -> 1.1.0 (new skill).
