Cleanup pass following the CoCounsel merge (#4) and Lexis removal (#5):
- Normalize whitespace and JSON indentation across plugin metadata files
- Sync marketplace.json with plugin.json (ip-legal description, Courtroom5 title field)
- Add missing ai-inventory and invention-intake rows to README skill reference
- Replace stale short-form skill names in customize/cold-start SKILL.md prose with canonical directory names across 11 plugins (same bug class as the /setup -> /cold-start-interview QA fix)
- Fix FYY -> FYI typo and a phantom WebFetch claim in launch-radar docs
- Address review findings: line-wrapped /check-claims, /renewals-due -> /renewal-tracker, stale /setup in references/, agent.yaml comment contradiction, redundant 'intake intake'
- Add root CLAUDE.md with validation conventions (claude plugin validate, I1-I11 invariants, frontmatter requirements) and a marketplace.json description + $schema
No behavioral changes. claude plugin validate passes clean.
Adds the Thomson Reuters CoCounsel Legal plugin (Westlaw Deep Research)
as a vendor-maintained plugin under a new external_plugins/ directory,
following the partner-built layout used elsewhere.
- external_plugins/cocounsel-legal/: plugin.json, .mcp.json (HTTP MCP
server with OAuth), deep-research skill, vendor README
- .claude-plugin/marketplace.json: register cocounsel-legal pointing at
./external_plugins/cocounsel-legal with Thomson Reuters as author
- README.md: document external_plugins/ in the repo layout, add an
'External / partner-built' section, list the CoCounsel Legal connector,
and add a skill reference entry
