Critical-review §4 E15 finding: agent files in .claude/agents/ are loaded
as Claude Code subagent system prompts and are a direct memory-poisoning
surface. Pre-v7.2.0 the scanner covered CLAUDE.md, .claude/rules/*.md,
memory/*.md, REMEMBER.md, .local.md, and .claude-plugin/plugin.json —
but not .claude/agents/*.md.
Single-line addition to MEMORY_FILE_PATTERNS:
/(?:^|\/)\.claude\/agents\/[^/]+\.md$/
The existing scan loop, scanForInjection integration, and severity-
mapping logic all apply unchanged. STRICT_FILES_PATTERN intentionally
NOT extended — agents may legitimately quote shell commands as examples
(consistent with CLAUDE.md treatment).
Tests: +3 cases in tests/scanners/memory-poisoning.test.mjs:
- "scans .claude/agents/*.md" (smoke test — at least one finding from
the new fixture)
- "agent file injection pattern detected"
- "agent file credential path detected"
New fixture: tests/fixtures/memory-scan/poisoned-project/.claude/agents/
poisoned-agent.md — agent with injection, credential ref, permission
expansion, and exfil URL. Triggers all 4 detection categories.
Suite: 1591 → 1594 (+3). All green.
Synthetic skill content mimicking the noise profile of frontend
animation projects (HTML5 canvas, framework env-vars, inline SVG data
URIs, CSS keyframes) plus exactly one genuine HITL trap signal.
Used by tests/scanners/skill-scanner-narrative.test.mjs (added in
v7.1.1) to exercise:
- content-extractor: HIGH HITL trap signal + framework env-var
references (process.env.REACT_APP_*, VITE_PUBLIC_*)
- entropy scanner: inline SVG data URI suppressed via line-context rules
The .llm-security-ignore file uses the SCANNER:glob format
(scanners/scan-orchestrator.mjs:34-40) — ENT:**/*.md suppresses any
entropy-scanner findings when the fixture is run through scan-orchestrator
in the Step 6 smoke test.
Part of v7.1.1 narrative-coherence patch.

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.
