New COL scanner detects skill-name collisions across plugins and
between user-level skills (~/.claude/skills/) and plugin-bundled
skills. Skill identity is the directory basename — matches how
enumerateSkills resolves names.
Detection rules (per docs/v5-namespace-research.md, confidence: medium):
- Plugin-vs-plugin same skill name → severity low (CA-COL-001)
- User-vs-plugin same skill name → severity medium (CA-COL-001)
- Plugin-vs-built-in collisions: out of scope for v5.0.0 (insufficient
verification — recorded for v5.0.1 follow-up).
Findings carry details.namespaces array with {source, name, path} for
every conflicting source — supports per-collision reporting downstream.
output.mjs: finding() helper now passes through optional `details`
field (scanner-specific structured payload).
scoring.mjs: COL → "Plugin Hygiene" (new area, 10 total). Posture test
updated from 9 → 10 area scores.
.gitignore: docs/v5-namespace-research.md is local-only (Step 22a
research output, gitignored per plan).
Fixture collision-plugins/fake-home/ has user skill `review` colliding
with plugin-a + plugin-b's `review` (medium severity), plus plugin-c's
unique `summarize` (no collision).
[skip-docs] reason: v5 plan fences off README/CLAUDE.md badge updates
to Session 5; Forgejo pre-commit-docs-gate hook requires this tag.
Tests: 617 → 625 (+8).

The mcp-tool-heavy fixture relies on node_modules/mcp-heavy/package.json
being committed so the v5 M1 tool-count detection test runs deterministically.
Add an unignore rule for tests/fixtures/**/node_modules/.
Add /ultraresearch-local for structured research combining local codebase
analysis with external knowledge via parallel agent swarms. Produces research
briefs with triangulation, confidence ratings, and source quality assessment.
New command: /ultraresearch-local with modes --quick, --local, --external, --fg.
New agents: research-orchestrator (opus), docs-researcher, community-researcher,
security-researcher, contrarian-researcher, gemini-bridge (all sonnet).
New template: research-brief-template.md.
Integration: --research flag in /ultraplan-local accepts pre-built research
briefs (up to 3), enriches the interview and exploration phases. Planning
orchestrator cross-references brief findings during synthesis.
Design principle: Context Engineering — right information to right agent at
right time. Research briefs are structured artifacts in the pipeline:
ultraresearch → brief → ultraplan --research → plan → ultraexecute.
