+## kepano/obsidian-skills (Special — from Obsidian Creator)
+
+Linus Kepano (Obsidian creator + Minimal theme) published official Agent Skills for Obsidian:
+
+| Skill | What It Teaches |
+|-------|----------------|
+| obsidian-markdown | Obsidian Flavored Markdown (callouts, embeds, wikilinks, properties) |
+| obsidian-bases | Obsidian Bases (.base files, views, filters, formulas) |
+| json-canvas | JSON Canvas spec (.canvas nodes/edges/groups) |
+| obsidian-cli | Vault management via Obsidian CLI |
+| defuddle | Extract clean Markdown from web pages (saves tokens) |
+
+> **Key signal**: This project validates that the Agent Skills format is the right standard.
+> These skills are platform-agnostic (Claude Code, Codex, OpenCode).
+

+
+## Popularity Snapshot (Traditional Plugins)
+
+| Plugin | Stars | Approach |
+|--------|-------|---------|
+| obsidian-copilot | 5,776 | Multi-provider vault chat |
+| obsidian-smart-connections | 4,357 | Semantic search + embeddings |
+| obsidian-textgenerator-plugin | 1,837 | Text generation |

+| obsidian-local-gpt | 569 | Local LLM |
+| obsidian-ai-tools | 272 | Supabase + OpenAI semantic search |
+
+---
+
+## Where claude-obsidian Wins
+
+1. **Hot cache** — session context mechanism is unique in the ecosystem
+2. **Canvas skill** — no other LLM Wiki project has a visual layer
+3. **Marketplace install** — most polished install experience
+4. **/save conversation** — filing chat sessions as wiki pages is unique
+5. **Pub quality docs** — README, install guide, demo GIFs
+6. **Dual repo** (public + community) — distribution model unique
+
+## Where claude-obsidian Has Gaps
+
+See [[cherry-picks]] for prioritized list with implementation notes.
+
+Top 5 gaps by impact:
+1. No delta tracking → re-ingests everything on every compile
+2. No URL ingestion → forces manual copy-paste
+3. No auto-commit → vault changes aren't versioned automatically
+4. No multi-depth query → one mode for all questions
+5. No vision input → can't ingest screenshots or images

+# Cherry-Picks: Feature Backlog
+
+> Sourced from ecosystem research 2026-04-08 | 16+ projects analyzed
+> Prioritized by: impact × implementation ease × uniqueness
+
+---
+
+## Tier 1 — Quick Wins (High Impact, Low Effort)
+
+### 1. URL Ingestion in /wiki-ingest
+**Source**: ekadetov/llm-wiki, Ar9av/obsidian-wiki
+**What it is**: Pass a URL directly to ingest instead of a file path. Agent fetches the page, cleans it, saves to `.raw/`, then ingests.
+**Current state**: Users must manually copy-paste web content.
+**How to add**: Detect `https://` prefix in ingest skill → WebFetch → save to `.raw/articles/` → proceed with normal ingest.
+**Bonus**: Pair with **defuddle** (kepano's web cleaner) for clean token-efficient extraction.
+
+### 2. Auto-Commit PostToolUse Hook
+**Source**: ballred/obsidian-claude-pkm, ekadetov/llm-wiki
+**What it is**: Every Write/Edit tool call in the vault triggers `git add -A && git commit -m "auto: [filename] [timestamp]"`.
+**Current state**: No auto-commit. Users must manually push.
+**How to add**: PostToolUse hook in hooks.json targeting Write + Edit tools, scoped to wiki/ directory.
+**Note**: Makes vault a proper version-controlled knowledge base automatically.
+
+### 3. defuddle Web Cleaning Skill
+**Source**: kepano/obsidian-skills
+**What it is**: A skill that wraps `defuddle-cli` — strips ads, nav, clutter from web pages before ingest. Reduces token usage ~40-60% on typical web articles.
+**How to add**: New `defuddle` sub-skill or reference in wiki-ingest. Requires `defuddle-cli` npm package.
+
+---
+
+## Tier 2 — Medium Effort, High Value
+
+### 4. Delta Tracking Manifest
+**Source**: Ar9av/obsidian-wiki
+**What it is**: `.raw/.manifest.json` tracking every ingested source — path, hash, timestamp, which wiki pages it produced. Re-ingest only processes new/changed files.
+**Current state**: Every `/wiki-ingest` call re-processes everything.
+**How to add**:
+  - On ingest: compute MD5 hash of source → check manifest → skip if unchanged
+  - On ingest: record `{path, hash, ingested_at, pages_created}` in manifest
+  - On update: re-process if hash changed, merge changes into existing pages
+
+### 5. Multi-Depth Query Modes
+**Source**: rvk7895/llm-knowledge-bases
+**What it is**: 3 query tiers in `/wiki-query`:
+  - **Quick** — hot.md + index.md only (~3 pages read)
+  - **Standard** — full wiki cross-reference + optional web search supplement
+  - **Deep** — parallel sub-agents, each researching a different angle
+**Current state**: One depth level.
+**How to add**: `/wiki-query quick <question>`, `/wiki-query deep <question>` flags in SKILL.md.
+
+### 6. /wiki-ingest Vision Support
+**Source**: Ar9av/obsidian-wiki
+**What it is**: Ingest images, screenshots, whiteboard photos by passing the image to a vision-capable model.
+**How to add**: Detect image extension → read as base64 → pass to Claude with vision prompt asking for transcription/description → treat result as text source → standard ingest pipeline.
+**Useful for**: Whiteboard photos from meetings, screenshots of web content, diagrams.
+
+---
+
+## Tier 3 — Bigger Features Worth Planning
+
+### 7. /adopt — Import Existing Vault
+**Source**: heyitsnoah/claudesidian, ballred/obsidian-claude-pkm
+**What it is**: `/adopt` analyzes an existing Obsidian vault, detects its organization method (PARA, Zettelkasten, LYT, plain), and wraps the LLM Wiki pattern around it without destroying existing structure.
+**Why it matters**: Currently, users must start fresh. This unlocks adoption by people with existing vaults.
+**Implementation**: Scan folder structure → classify patterns → generate CLAUDE.md mapping existing folders to wiki roles → non-destructive.
+
+### 8. Productivity Wrapper (Daily/Weekly Reviews)
+**Source**: ballred/obsidian-claude-pkm
+**What it is**: Optional `/daily` and `/weekly` skills that connect goal tracking to the knowledge base.
+**Could be a separate plugin** rather than bundled into claude-obsidian.
+**Goal cascade**: 3-Year Vision → Yearly Goals → Projects → Weekly → Daily.
+
+### 9. Multi-Agent Compatibility (Cursor, Windsurf, Codex)
+**Source**: Ar9av/obsidian-wiki, kepano/obsidian-skills
+**What it is**: A `setup.sh` or `/wiki-convert` command that generates `.cursor/rules/`, `AGENTS.md`, `GEMINI.md` equivalents so the wiki skills work in other coding agents.
+**Note**: kepano already published skills in Agent Skills format — claude-obsidian is already in that format. Just needs the adapter files.
+
+### 10. Marp Presentation Output
+**Source**: rvk7895/llm-knowledge-bases, ekadetov/llm-wiki
+**What it is**: `/wiki-query --slides <topic>` generates a Marp presentation from wiki content, saved to `output/`.
+**Requires**: `marp-cli` npm package.
+
+---
+
+## Tier 4 — Research / Ecosystem Plays
+
+### 11. obsidian-memory-mcp Integration
+**Source**: YuNaga224/obsidian-memory-mcp
+**What it is**: Connect the MCP server that stores Claude's memories as Markdown entities with `[[wikilinks]]` → they appear in Obsidian graph view automatically.
+**How to add**: Point MEMORY_DIR to the wiki/entities/ directory — entity memory pages become proper wiki pages.
+
+### 12. obsidian-bases Skill (from kepano)
+**Source**: kepano/obsidian-skills
+**What it is**: Teach Claude how to create and edit Obsidian Bases (.base files) for dynamic tables, views, and filters.
+**Why**: Obsidian Bases is a new core feature — no other LLM Wiki project teaches Claude about it yet.
+
+### 13. Schema-Emergent Vault Mode
+**Source**: Ar9av/obsidian-wiki
+**What it is**: Alternative /wiki mode where the vault structure is not scaffolded upfront but emerges from ingested content. Good for exploratory knowledge building vs. structured domains.
+**How**: Skip the scaffold step; let wiki-ingest create folders/categories organically based on source content.
+
+---
+
+## Competitive Positioning
+
+After this research, claude-obsidian's unique advantages remain:
+- **Hot cache** — no one else has this session context mechanism
+- **Canvas visual layer** — unique in the LLM Wiki category
+- **/save conversation** — filing chat → wiki is a distinct workflow
+- **Marketplace polish** — best install experience in category
+- **Community distribution** (avalonreset-pro)
+
+The ecosystem is maturing fast. Tier 1 items (URL ingest, auto-commit, defuddle) should ship in v1.3.0 to stay ahead.
+
+---
+
+## Implementation Priority
+
+```
+v1.3.0 (quick wins):
+  - URL ingestion (#1)
+  - Auto-commit hook (#2)
+  - defuddle integration (#3)
+
+v1.4.0 (quality):
+  - Delta tracking (#4)
+  - Multi-depth query (#5)
+
+v1.5.0 (expansion):
+  - Vision ingest (#6)
+  - /adopt command (#7)
+  - Multi-agent compat (#9)
+
+Future:
+  - Productivity wrapper (#8)
+  - Marp output (#10)
+  - Memory MCP integration (#11)

+# Ar9av/obsidian-wiki
+
+**Type**: Claude Code plugin (skill-based)
+**URL**: https://github.com/Ar9av/obsidian-wiki
+**Pattern**: Karpathy LLM Wiki
+**Unique claim**: Works with any AI coding agent via `setup.sh`
+
+## What It Does
+
+Framework for AI agents to build and maintain an Obsidian wiki using the Karpathy LLM Wiki pattern. The key differentiator: a single `setup.sh` deploys the skills to 7 different agents simultaneously.
+
+## Agent Compatibility Matrix
+
+| Agent | Bootstrap | Skills Dir |
+|-------|-----------|-----------|
+| Claude Code | CLAUDE.md | `.claude/skills/` |
+| Cursor | `.cursor/rules/obsidian-wiki.mdc` | `.cursor/skills/` |
+| Windsurf | `.windsurf/rules/` | `.windsurf/skills/` |
+| Codex (OpenAI) | AGENTS.md | `~/.codex/skills/` |
+| Gemini/Antigravity | GEMINI.md | `~/.gemini/antigravity/skills/` |
+| OpenClaw | AGENTS.md | `.agents/skills/` |
+| GitHub Copilot | `.github/copilot-instructions.md` | — |
+
+## Key Innovations
+
+### Delta Tracking Manifest
+`.manifest.json` tracks every ingested source: path, hash, timestamp, which wiki pages produced. Only processes new/changed files. Solves the "re-ingest everything" problem.
+
+### 4-Stage Pipeline
+1. **Ingest** — reads source (PDF, JSONL, text, conversation exports, images)
+2. **Extract** — pulls concepts, entities, claims, relationships, open questions
+3. **Resolve** — merges new knowledge against existing wiki (no duplication)
+4. **Schema** — structure emerges from sources, not predefined
+
+### Vision Support
+Images, screenshots, whiteboard photos ingestable with vision-capable model. Each page gets 1-2 sentence `summary:` in frontmatter for preview without opening.

+# Claudian (YishenTu/claudian)
+
+**Type**: Native Obsidian plugin (TypeScript, embedded Claude Code/Codex)
+**URL**: https://github.com/YishenTu/claudian
+**Install**: BRAT or manual (not yet in community store)
+
+## What It Does
+
+Embeds Claude Code (or Codex CLI) directly inside Obsidian as a sidebar chat. The vault becomes the agent's working directory — all Claude Code tools work natively inside Obsidian.
+
+## Key Features
+
+### Inline Edit with Word-Level Diff
+Select text in a note + hotkey → Claude proposes edit with word-level diff preview → one-click apply. Best-in-class inline editing in the Obsidian AI ecosystem.
+
+### Plan Mode (Shift+Tab)
+Agent explores and designs before implementing. Presents a plan for approval before any file changes. Mirrors Claude Code's own plan mode.
+
+### @mention System
+Type `@` to reference:
+- Vault files
+- Sub-agents
+- MCP servers
+- Files in external directories (outside vault)
+
+### Instruction Mode (#)
+Add refined custom instructions directly from chat input — persisted for the session.
+
+### MCP Server Integration
+Connect external tools via stdio, SSE, or HTTP. Claude manages vault MCP in-app; Codex uses CLI-managed config.
+
+### Multi-Tab Conversations
+Multiple chat tabs, conversation history, fork, resume, compact mode.
+
+## Privacy
+- No telemetry
+- Settings stored in `vault/.claudian/`
+- Claude files in `vault/.claude/`
+- Transcripts in `~/.claude/projects/`
+
+## Relevance to claude-obsidian
+Claudian is a native plugin (different category) but its Plan Mode, @mention, and inline edit patterns could inspire new features in claude-obsidian skills — particularly for the canvas and wiki-query workflows.

+# Nexus (formerly Claudesidian MCP)
+
+**Type**: Native Obsidian plugin + MCP bridge
+**URL**: https://github.com/ProfSynapse/claudesidian-mcp
+**Current name**: Nexus MCP for Obsidian
+**Install**: `.obsidian/plugins/nexus/`
+
+## What It Does
+
+Full Obsidian plugin with two modes:
+1. **Native chat inside Obsidian** — connect any AI provider
+2. **MCP bridge** — expose vault to Claude Desktop, Claude Code, Codex CLI, Gemini CLI, Cursor, Cline
+
+## Key Features
+
+- **Workspace memory** — persistent context across sessions stored as JSONL, automatically included in Obsidian Sync
+- **Task management** — projects, tasks, blockers, dependencies tracked within vault
+- **Semantic search** — search notes + past conversations by meaning
+- **Inline editing** — edit selected text in notes
+- **PDF + audio → Markdown** — conversion on right-click or auto-on-add
+- **Web page capture** — open URL in Obsidian, save as Markdown/PNG/PDF
+- **Mobile support** — native chat works on iOS/Android
+- **Two-tool architecture** — dedicated tools for read vs write actions
+
+## Storage Architecture
+
+Data stored as JSONL files in `.obsidian/plugins/nexus/data/`. This is included in Obsidian Sync automatically (unlike the `.nexus/` folder of v1). SQLite cache is local-only, rebuilt from JSONL on each device.
+
+## Relevance to claude-obsidian
+
+Nexus is in a different category — it's a native TypeScript Obsidian plugin, not a Claude Code skill plugin. The two don't compete directly, but its workspace memory and task management patterns are cherry-pickable.

+# ballred/obsidian-claude-pkm
+
+**Type**: Claude Code plugin (skill-based PKM system)
+**URL**: https://github.com/ballred/obsidian-claude-pkm
+**Version**: 3.1
+**Tagline**: "Not another PKM starter kit. An execution system."
+
+## What It Does
+
+Connects a 3-year vision cascade to daily task execution, using Claude as an accountability partner. Every layer is linked — daily notes surface the weekly ONE Big Thing, which links to active projects, which link to yearly goals.
+
+## Goal Cascade
+
+```
+3-Year Vision → Yearly Goals → Projects → Monthly Goals → Weekly Review → Daily Tasks
+```
+
+Each layer has a dedicated skill: `/goal-tracking`, `/project`, `/monthly`, `/weekly`, `/daily`, `/review`.
+
+## Key Innovations
+
+### Auto-Commit via PostToolUse Hook
+Every Write/Edit tool call triggers `git add -A && git commit` automatically. Vault is always versioned.
+
+### /adopt Command
+Scans an existing Obsidian vault, detects its organization method (PARA, Zettelkasten, LYT, plain folders), maps folders interactively to the PKM layers, generates config files. Non-destructive.
+
+### 4 Specialized Agents with Memory
+- `goal-aligner` — audits activity vs. stated goals, flags misalignment
+- `weekly-reviewer` — facilitates 3-phase weekly review, learns reflection style
+- `note-organizer` — fixes broken links, consolidates duplicates
+- `inbox-processor` — GTD-style inbox processing
+
+Uses `memory: project` so agents remember patterns across sessions.
+
+### Productivity Coach Output Style
+`/output-style coach` transforms Claude into an accountability partner — challenges assumptions, asks powerful questions, points out goal-action misalignment.
+
+## Architecture
+
+Zero dependencies (bash + markdown only). Path-specific rules loaded contextually. Session init surfaces ONE Big Thing, active project count, days since last review.

+# kepano/obsidian-skills
+
+**Type**: Agent Skills (Agent Skills standard)
+**URL**: https://github.com/kepano/obsidian-skills
+**Author**: **Linus Kepano** — creator of Obsidian + Minimal theme
+**Install**: `/plugin marketplace add kepano/obsidian-skills`
+
+## Why This Matters
+
+This repo is from the creator of Obsidian. It:
+1. Validates that the Agent Skills standard is the right format for Obsidian AI tools
+2. Provides the canonical reference for how to teach Claude about Obsidian-specific syntax
+3. Covers Obsidian Bases — a new core Obsidian feature that no other AI project supports yet
+
+## Skills
+
+| Skill | What It Teaches Claude |
+|-------|----------------------|
+| `obsidian-markdown` | Full Obsidian Flavored Markdown: wikilinks, embeds, callouts, properties, tags |
+| `obsidian-bases` | Obsidian Bases (.base files): views, filters, formulas, summaries |
+| `json-canvas` | JSON Canvas spec: nodes, edges, groups, connections |
+| `obsidian-cli` | Vault management, plugin/theme dev via Obsidian CLI |
+| `defuddle` | Extract clean Markdown from web pages — removes ads, nav, clutter |
+
+## defuddle
+
+The `defuddle` skill wraps `defuddle-cli`. When ingesting web content, running defuddle first:
+- Strips ads, navigation, footers
+- Reduces token usage ~40-60% on typical web pages
+- Produces cleaner Markdown that fits better in context window
+
+This is a direct cherry-pick for claude-obsidian's ingest pipeline.
+
+## Multi-Platform
+
+Works with Claude Code, Codex CLI, and OpenCode out of the box.
+

+# rvk7895/llm-knowledge-bases
+
+**Type**: Claude Code plugin (Marketplace)
+**URL**: https://github.com/rvk7895/llm-knowledge-bases
+**Install**: `/plugin marketplace add rvk7895/llm-knowledge-bases`
+
+## What It Does
+
+Turns raw research material into an LLM-maintained Obsidian wiki with multi-depth querying and rich output formats. Adds a deep research pipeline with parallel agents on top of the Karpathy pattern.
+
+## Key Innovations
+
+### 3-Depth Query System
+- **Quick** — answers from wiki indexes and summaries only (minimal reads)
+- **Standard** — cross-references full wiki, supplements with web search
+- **Deep** — multi-agent parallel web search pipeline
+
+### Output Formats
+Beyond Markdown: Marp slides, matplotlib charts. All outputs saved to `output/` and optionally filed back into wiki.
+
+### Skills Set
+| Skill | Purpose |
+|-------|---------|
+| `/kb-init` | One-time setup |
+| `/kb compile` | Raw → wiki |
+| `/kb query` | Query with depth |
+| `/kb lint` | Health check |
+| `/kb evolve` | Maintenance pass |
+| `/research <topic>` | Structured research outline |
+| `/research-deep` | Parallel agents per outline item |
+| `/research-report` | Compile deep results → Markdown |
+
+### X/Twitter Integration
+Via Smaug tool (`npm install -g @steipete/bird`). Ingests tweets, threads, bookmarks from X/Twitter by pasting URL. Uses session cookies (read-only, personal use).
+
+## Attribution
+Built on Karpathy pattern + Weizhena's Deep Research skills adapted for the research pipeline.
