init — scaffold a shared-brain kb folder

What this creates

A self-contained directory — plain markdown, no database, no server — that is:

A memory protocol. AGENTS.md (the full read/write/dream rules), CLAUDE.md (thin pointer for Claude Code), DREAM.md (the consolidation pass), MEMORY.md (the index every agent reads first).
An OKF v0.1 bundle. memory/ is the bundle root; every note is one .md file with a type in frontmatter. Conforms to OKF v0.1 — see the companion okf skill/plugin for deeper bundle authoring and validation.
A capture inbox. raw/inbox/ for low-ceremony daily notes; raw/ for immutable source docs.
Its own CLI and tooling, vendored into scripts//bin/ so the folder keeps working even if this Claude plugin is later removed: bin/kb (capture/lint/sync/gen/viz/wire), scripts/render_okf_viewer.py (regenerates memory/**/index.md + a self-contained viz.html graph viewer), scripts/ lint.sh, scripts/sync.sh, scripts/wire.sh.

This is the generic, brand-neutral form of a personal "shared brain" pattern — it ships with no memory content, no assumed git remote, and no personal branding. Everything it writes is a template for the user to fill in.

When to use

"set up a kb / shared brain / persistent memory folder for me"
"init ~/kb" or "bootstrap my knowledge base"
The user wants cross-session, cross-agent memory but has none yet.

If a kb already exists at the target (has AGENTS.md or memory/), this skill is still safe to run — see Idempotency below — but check first whether the user actually wants dream (consolidate existing notes) instead of init.

Steps

Resolve the target path. Default $HOME/kb. Use $KB_DIR if set, or a path the user gave explicitly. Confirm the path with the user if ambiguous.
Scaffold. Run the bundled script with an absolute path (it does not expand ~):
```
bash "${CLAUDE_PLUGIN_ROOT}/skills/init/scripts/scaffold.sh" "$HOME/kb"
```
It is idempotent — creates missing files, chmods scripts executable, seeds starter memory/{user,feedback,reference,projects,topics}/ groups, and never overwrites a file that already exists in the target. It ends by running render_okf_viewer.py once so memory/index.md and viz.html exist immediately.
Report what happened: how many files were created vs. skipped (pre-existing), and the target path.
Offer, but do not run automatically, three follow-ups — each changes something outside the new folder or is otherwise consequential, so ask first:
- PATH. Suggest adding export PATH="<target>/bin:$PATH" to the user's shell rc. Don't edit their .zshrc/.bashrc yourself unless they ask.
- Version control. Offer git init (and git remote add origin <url> if they have one). Skip silently if they don't want git.
- Wiring. <target>/scripts/wire.sh on adds a small marked block to ~/.claude/CLAUDE.md (and ~/.codex/AGENTS.md / ~/.config/opencode/ AGENTS.md if those tools are present) so every future session auto-reads the kb. This edits files outside the scaffolded folder and affects every future session — explain what it does and get explicit confirmation before running it. wire.sh off cleanly reverses it.
If the user wants example notes, don't invent personal facts — either leave memory/ empty for them to fill in via kb capture, or ask what to record.

After scaffolding

Point to memory/_TEMPLATE.md for the note format and AGENTS.md for the full protocol — both are self-documenting inside the new folder.
For ongoing maintenance (merge duplicates, prune stale notes, rebuild the index), use this plugin's dream skill against the new kb.
For richer OKF authoring/validation beyond what bin/kb gen covers (custom concept types, validate_okf.py conformance checks), use the okf plugin.
kb viz (or bin/kb viz before PATH is set) opens the graph viewer any time after notes are added.

Idempotency & safety

scaffold.sh only ever creates files that don't already exist — re-running it against a partially-set-up or already-populated kb is safe and adds nothing to files it finds present.
It never touches anything outside <target> — no global config, no shell rc, no git remote. Those are the explicit, confirm-first follow-ups above.
It writes no personal data — the scaffolded files are generic templates.

Checklist

Resolved target path (arg, $KB_DIR, or confirmed default ~/kb).
Ran scaffold.sh with an absolute path; reported created vs. skipped files.
memory/index.md and viz.html exist (scaffold.sh generates them).
Offered PATH / git init / wire as separate, confirm-first steps — did not edit anything outside the target folder without asking.
Did not invent personal facts to seed memory/ with.
