# Investigator-API Agent — Persistent Memory

> **Persistent diary cross-session.** Auto-injected first ~200 lines at spawn (L1 HOT).
> Update BEFORE every stop. Tiered Memory v1: L1 HOT soft-cap ~30KB · L2 `archive/` on-demand · L3 RAG `search_memory` just-in-time. Keep entry ≤ 1.5K chars (gotcha #53).
> **NEW agent S39 (2026-05-29)** — split từ investigator (external research half). Internal audit history ở `investigator-codebase`.

## 🎯 Role baseline

Read-only EXTERNAL research specialist. WebFetch/WebSearch official docs + NuGet/npm CVE + FE lib eval + cross-project reference (NamGroup/DH_Y_DUOC/BVAAU). Tools: Read, Bash, WebFetch, WebSearch + 5 RAG MCP. Output: findings + source URLs ≤ 500 words. Skill: `dependency-audit-erp`.

## 🚫 Split boundary
- ✅ MINE: external docs, CVE scan, lib license+bundle eval, cross-project pattern port
- ❌ NOT: internal codebase audit / SQL schema / grep symbol → `investigator-codebase`

## 🔑 Dependency pin constraints (flag violation)
- MediatR `12.4.1` (gotcha #1) · Swashbuckle `6.9.0` (gotcha #2) · Node CI `20.x` · LibreOffice `25.8.6` · @microsoft/signalr `8.0.7`
- New dep eval: license MIT? bundle gzipped impact? (vd FullCalendar v6 React MIT verified S36 — daygrid/timegrid OK, Premium chỉ scheduler — SOL chọn custom HTML grid save ~80KB instead)

## 🌐 Trusted source URLs
- `anthropic.com/engineering/` · `cognition.ai/blog/` · `learn.microsoft.com/en-us/aspnet/core/` + `/ef/core/` · `tanstack.com/query/latest` · `ui.shadcn.com` · `philschmid.de` · `eugeneyan.com` · `hamel.dev`

## 📂 Cross-project reference paths
- NamGroup `D:\Dropbox\CONG_VIEC\NAMGROUP\SOURCECODE_CÔNG_TY\NAMGROUP\` (Phase 10 port — TblNhanVien/TblPhongHop/TblResource patterns)
- DH_Y_DUOC `D:\Dropbox\CONG_VIEC\DAI_Y_DUOC\DH_Y_DUOC_SOURCECODE\DH_Y_DUOC\` (clean arch + CQRS)
- BVAAU `D:\Dropbox\CONG_VIEC\BENHVIEN_A_AU\SOURCE_CODDE\` (multi-agent config — 7 agent split reference)

## 📅 Recent activity (last 10 FIFO)

- **2026-05-29 (S39 agent split setup):** NEW agent created từ split investigator. Seeded external-research half. Prior cross-project audits (NamGroup Phase 10 port G-H1/G-O2 + FullCalendar eval S36 + BVAAU 7-agent config S39) absorbed into role baseline.
- **2026-05-29 (S40 FIRST SPAWN — smoke-verify + RAG fleet report):** Agent load OK confirmed. `list_projects` → 7 project, total **39,798 chunks**. Rerank pipeline LIVE verdict **PASS** (search_memory scope=self use_rerank=true → top rerank_score **0.8789**, 3 results all carry rerank_score). Staleness >5d (vs 05-29): dh_y_duoc (05-23, 6d) / namgroup_main (05-22, 7d) / ashico_erp (05-22, 7d). solution_erp 05-28 fresh-ish but missing S37-S39 content. `shared_global` = 0 chunks (chưa promote pattern nào). MINOR drift: namgroup_main actual 11306 (brief said 11305). vipix_ai_infra (1652) = AI_INFRA hub root `D:\...\AI_INFRA`. No re-ingest performed (report-only).
- **2026-06-07 (Harness 1 H3 — plugin/skill adoption audit):** Browsed marketplace `claude-plugins-official` (full marketplace.json ~200+ plugin; local folder 35). Enabled user-global (`~/.claude/settings.json`) = **15 plugin**. **KEY surprise:** `sql-database-assistant` + `frontend-design` + `skill-creator` + `code-reviewer` exist as **standalone user-global skills** at `~/.claude/skills/` (auto-available every project — NO plugin enable needed). `~/.claude/skills/` has 23 standalone skills. Value-locus verdict: frontend-design=skill-only (clean); code-modernization=**agent-bearing** (5 agent incl security-auditor/test-engineer + 7 cmd — NOT skill-only); pr-review-toolkit + feature-dev = agent-bearing, BOTH ship agent `code-reviewer` → **name-collision** ×2 + collides roster `reviewer.md`. csharp-lsp = **Windows no-op** (`csharp-ls` NOT on PATH, needs `dotnet tool install`). code-review = command-only, gh-CLI based → partial no-op (project = Gitea not GitHub). session-report = node `.mjs` (Win-OK, Node 20). Roster ACTUAL = 8 agent (cicd-monitor/frontend-designer/implementer-backend|frontend/investigator-api|codebase/reviewer/test-specialist); "8→10" = planned H1 tooling-auditor + H2 harvest-curator. Recommend: GỘP skill vào sub hiện-có, KHÔNG enable agent-bearing plugin (roster đủ). Report-only.
