+## What is BeadBoard
+
+BeadBoard is a real-time dashboard for `bd`-backed agent work — it surfaces agent liveness, state transitions, swarm progress, and inter-agent mail in a live UI. The **human uses the BeadBoard UI** to observe and coordinate; agents use this skill to emit the signals (heartbeats, state transitions, mail) that drive what the dashboard displays.
+
+**Agents almost never work inside the BeadBoard repo.** You work in your own project repo. `bb` and `bd` are globally available on PATH. Scripts used by this skill (preflight, mail shim, etc.) are bundled inside this skill folder — your agent runtime knows where this skill is installed and provides the path as `{baseDir}` (the directory containing this SKILL.md).

+ls project.md 2>/dev/null && echo "EXISTS" || echo "MISSING"
-node skills/beadboard-driver/scripts/ensure-bb-mail-configured.mjs

-Expected outcome:
+**MISSING → you are the first agent in this project.** Run the [Bootstrap Checklist](#bootstrap-checklist) below, then return here.

-- `mail.delegate` points to `bb-mail-shim.mjs`
-- `BB_AGENT` or `BD_ACTOR` identity is available
 
-If either script fails, stop and fix environment first.
+**EXISTS → read the Environment Status Cache table at the top of `project.md`.**
 
-### Step 2: Create Agent Bead Identity

+- Any row `fail` or `unknown` → run only that specific check (see Step 1), fix it, update `project.md`, continue.

+
+#### Bootstrap Checklist
+
+> `{baseDir}` is the absolute path to the directory containing this SKILL.md, injected automatically by your agent runtime (Claude Code, Codex, etc.). If your runtime does not auto-substitute it, find the skill installation path and substitute the absolute path manually.
+
+Run once, in order, when `project.md` is missing.
+
+**A. Check `bd` (beads-cli)**
 
 ```bash
-bd create --title="Agent: <role-name>" --description="<scope>" --type=task --priority=0 --label="gt:agent,role:<orchestrator|ui|graph|backend|infra>"
+which bd 2>/dev/null || where bd 2>/dev/null
 ```
 
+If missing:
+```bash
+npm install -g beads-cli
+```
+
+**B. Initialize beads database (if not already present)**
+
+```bash
+ls .beads 2>/dev/null && echo "EXISTS — skip" || bd init
+```
+
+Required before any `bd config` commands. Skip if `.beads` already exists.
+
+**C. Check `bb` (BeadBoard)**
+
+```bash
+which bb 2>/dev/null || where bb 2>/dev/null
+```
+
+If missing — `bb` is required for coordination. Ask the user:
+
+> "BeadBoard is not installed. It is required for agent coordination. Would you like me to install it now? I'll clone the repo and install it globally."
+
+If the user agrees:
+```bash
+git clone https://github.com/zenchantlive/beadboard.git ~/beadboard
+cd ~/beadboard && npm install && npm install -g .
+```
+
+**D. Configure mail delegate**
+
+```bash
+node {baseDir}/scripts/setup-mail-delegate.mjs
+```
+
+Self-resolves the shim absolute path and runs `bd config set mail.delegate` automatically.
+
+**E. Run session preflight**
+
+```bash
+node {baseDir}/scripts/session-preflight.mjs
+```
+
+Must pass before continuing. Checks `bd`, `bb`, and confirms delegate is set.
+
+**F. Create `project.md`**
+
+```bash
+cp {baseDir}/project.template.md ./project.md
+```
+
+Fill in every field in the Environment Status Cache table and Project Identity section. Set each verified row to `pass` with today's date. This is what saves the next agent from re-running all of the above.
+
+Append to the Session Log:
+```
+| YYYY-MM-DD | `<your-agent-bead-id>` | Initial project.md created, all checks pass |
+```
+
+---
+
+### Step 1: Environment Check (Skip If project.md All Green)
+
+**Only run this step if project.md has a `fail` or `unknown` row.**
+
+Run only the failing check:
+
+| Row failed | Command to fix |
+|-----------|----------------|
+| `bd` on PATH | `npm install -g beads-cli` |
+| `bb` on PATH | clone + `npm install -g .` (see Bootstrap C) |
+| `.beads` db | `bd init` (see Bootstrap B) |
+| `mail.delegate` | `node {baseDir}/scripts/setup-mail-delegate.mjs` |
+| `session-preflight` | `node {baseDir}/scripts/session-preflight.mjs` — fix what it reports |
+
+`{baseDir}` is the directory containing this SKILL.md. Your agent runtime substitutes it automatically.
+
+After fixing: update that row in `project.md` to `pass` with today's date.
+
+> See [Platform Notes](#platform-notes) if running on Windows native or WSL2.
+
+### Step 2: Create Agent Bead Identity + Verify Mail
+
+```bash
+bd create --title="Agent: bb-<role-name>" --description="<scope>" --type=task --priority=0 --label="gt:agent,role:<orchestrator|ui|graph|backend|infra>"
+```
+
+```bash
+# Register in bb coordination system and set identity
+bb agent register --name <role-name> --role <orchestrator|ui|graph|backend|infra>
+export BB_AGENT=<role-name>
+```
+
+> **Naming convention:** Name your `bd` bead `bb-<role-name>` (e.g. `bb-silver-scribe`). Register the same name in `bb` as `<role-name>` (e.g. `silver-scribe`). Set `BB_AGENT=<role-name>`. This bridges both identity systems: `bd agent state bb-silver-scribe ...` uses the bead ID; `bd mail send` uses `BB_AGENT` automatically.
+
+| Term | Example | Used where |
+|------|---------|------------|
+| `<role-name>` | `silver-scribe` | `bb agent register --name`, `BB_AGENT`, `bd mail --to` |
+| Bead title | `bb-silver-scribe` | `bd create --title` |
+| `<agent-bead-id>` | `beadboard-0m9` | `bd agent state`, `bd slot set`, `bd update --assignee` |
+| `BB_AGENT` value | `silver-scribe` | Set via `export`; auto-injected into all `bd mail` calls |
+
+Now that BB_AGENT is set, verify the full mail stack:
+
+```bash
+node {baseDir}/scripts/ensure-bb-mail-configured.mjs
+```
+
+Expected: `ok: true` with matching delegate and actor. If it fails, see [Failure Modes](#use-the-right-doc-map).

+## Platform Notes
+
+### Environment Variable Syntax
+
+| Shell | Command |
+|-------|---------|
+| bash / zsh (WSL2, Linux, macOS) | `export BB_AGENT=<name>` |
+| PowerShell (Windows native) | `$env:BB_AGENT = "<name>"` |
+| cmd.exe (Windows native) | `set BB_AGENT=<name>` |
+
+### Mail Delegate Path Format
+
+When configuring `bd config set mail.delegate "node <path>/bb-mail-shim.mjs"`:
+
+| Environment | Path format example |
+|-------------|---------------------|
+| WSL2 | `node /mnt/c/Users/<you>/codex/beadboard/skills/beadboard-driver/scripts/bb-mail-shim.mjs` |
+| Windows native | `node C:\Users\<you>\codex\beadboard\skills\beadboard-driver\scripts\bb-mail-shim.mjs` |
+
+### Binary Detection
+
+The preflight script checks `bd` and `bb` are on `PATH`. On native Windows, the system uses `where` instead of `which`. If preflight reports a binary as missing despite it being installed, run `where bd` and `where bb` from your shell to verify, and ensure you are running from a shell where `PATH` is correctly populated.
