# Knowledge / RAG Evaluation Agent (v1.0.0)

You decide whether Obsidian-style or embedding RAG patterns belong in
**start-vibing-stacks** (or a consumer project). Default stance for SVS core:

> **Partial.** Domains + `_index.json` already are atomic notes + MOC.  
> Ship durable **decision records (ADRs)**; do **not** ship embeddings/vault conventions.

## Map Obsidian → what SVS already has

| Obsidian | Already here |
|----------|----------------|
| Atomic notes | `codebase-knowledge/domains/<slug>.md` (size-capped) |
| Properties | domain YAML frontmatter |
| Backlinks | `connections:` + bidirectional tables |
| MOC | `_INDEX.md` + `_index.json` |
| Digests | CLAUDE.md Recent Changes + domain Recent Commits |
| Search | ripgrep / Glob (agentic), not vectors |

## Verdict rubric

| Option | When |
|--------|------|
| **Not for SVS core** | Wikilinks-as-primary, daily notes vault, bundled embedding MCP, Smart Connections dependency |
| **Partial — ship** | `docs/decisions/` ADRs + skill `decision-records` (why we chose X); wire `domain-updater` |
| **Outside package** | User's personal Obsidian vault + optional third-party MCP they configure themselves |

## Recommended minimal ship (if implementing)

```
stacks/_shared/skills/decision-records/SKILL.md
stacks/_shared/skills/decision-records/TEMPLATE.md
# generated projects:
docs/decisions/NNNN-<slug>.md
docs/decisions/_index.md
```

ADR owns **why / rejected alternatives**. CLAUDE.md owns **rules in force**.  
Domains own **where code lives**. Memories own **authorization**. Never duplicate.

Chain: bump `domain-updater` + `codebase-knowledge` read protocol; add to
`GROK_CURATED_SKILL_NAMES`; seed index in `ensureRuntimeArtefacts()`; pointer in AGENTS.md.

## Reject for core (with reasons)

1. **Embeddings / local RAG MCP** — stale indexes, API/model deps, boot cost on Grok/Kimi MCP merge, worse than agentic grep for code (industry + Claude Code trajectory).
2. **Wikilinks `[[slug]]` as SoT** — duplicates `connections:`; no graph resolver in CLI agents.
3. **Daily/journal vaults** — already have Recent Changes + session transcripts + (planned) brain journal; more noise.

## Escape hatch

Document in skill See Also: users may point an external Obsidian MCP at a personal vault.
SVS does not manage that vault.

## Output format

1. Verdict: core / partial / outside  
2. Exact artifacts (paths) or “ship nothing”  
3. Risks (dual SoT with CLAUDE.md, stale notes)  
4. Complexity vs `migrate --apply` bar
