obsidian-save
The obsidian-save command scans conversations to extract vault-worthy information including decisions, tasks, people, projects, ideas, and content opportunities, then deploys parallel agents to organize and store items by type while searching for duplicates and updating daily notes with links to saved material. Use this when concluding a productive conversation to capture actionable insights and reference material into an Obsidian vault without creating orphaned notes.

Use the obsidian-second-brain skill. Execute `/obsidian-save`:
1. Read `_CLAUDE.md` first if it exists in the vault root
2. Scan the entire conversation and identify all vault-worthy items: decisions, tasks, people mentioned, projects started, ideas, learnings, deals, mentions/shoutouts, AND content-worthy items (hooks, data points, swipe-file material, research findings)
3. Group items by type: people, projects, tasks, decisions, ideas, deals, content
4. Spawn parallel subagents - one per group - so all note types are handled simultaneously:
- **People agent**: search for each person, create or update notes, log interactions
- **Projects agent**: search for each project, create or update notes
- **Tasks agent**: parse tasks, add to the right kanban columns
- **Decisions agent**: find relevant project notes, append to Key Decisions sections
- **Ideas agent**: search Ideas/ for related notes, create or append
- **Content agent** (if a `social-media/` folder exists in the vault): scan for content-worthy items and route them:
- **Hooks, angles, contrarian takes** → append to `social-media/ideas.md` (dated bullet)
- **Specific numbers, stats, reusable data points** → append to `social-media/data-points.md` (with source)
- **External posts that hit + why** → append to `social-media/swipe-file.md` (link + reason)
- **Research findings, frameworks, methodologies** → create `social-media/research/YYYY-MM-DD — topic.md`
5. After all agents complete: update today's daily note with links to everything saved
6. Report back: a clean list of what was saved and where
Search before creating anything - duplicate notes are vault rot. Propagate every write to boards, daily note, and linked notes. Never create an orphaned note.
The content agent only runs if `social-media/` exists in the vault. If it doesn't exist, skip silently - don't create the folder unprompted.

**AI-first rule:** Every note created or updated by this command MUST follow `references/ai-first-rules.md` - `## For future Claude` preamble, rich frontmatter (`type`, `date`, `tags`, `ai-first: true`, plus type-specific fields), recency markers per external claim, mandatory `[[wikilinks]]` for every person/project/concept referenced, sources preserved verbatim with URLs inline, and confidence levels where applicable. The vault is for future-Claude retrieval - not human reading.
**Anti-fabrication:** Search exhaustively before claiming any note, person, or file is absent - false absence is the most common failure mode - and never invent facts, entities, or dates (mark unknowns as `TBD`). See the anti-fabrication and search-completeness hard rules in `references/ai-first-rules.md`.>

Surface 3-5 next-direction candidates by reading ungraduated ideas, open project questions, and orphan research notes - what is worth working on next
Vault-first source-grounded research via Gemini File Search. One command, no browser. The grounded parallel to /research-deep (which is open-web via Perplexity).
Generate a decision record when the vault structure changes - the vault knows why it knows what it does
Read Google Calendar and write an AI-first snapshot to the vault - today, week, next week, or a custom range
Scan a codebase and write a maintained set of architecture notes into the vault - overview, per-module notes, key decisions. Re-run to refresh without clobbering your edits
