+Bootstrap now covers two scenarios:
+- Fresh install: CLI + adapter installation, `uwf setup` configuration, skill installation, end-to-end verification
+- Upgrade: package update, skill regeneration, breaking change migrations (e.g. $START new/resume)

-Install or update the uwf (United Workforce) skills for your agent.
+Set up or upgrade uwf (United Workforce) — from zero to running your first workflow.
 
-## Steps
+## Scenario A: Fresh Install
 
-1. **Check if uwf CLI is installed:**
+### Step 0 — Environment pre-flight check
+
+Run ALL checks below BEFORE installing anything. If any check fails, fix it first — do NOT skip ahead.
+
+\`\`\`bash
+# 1. Node.js
+node --version   # need v20+
+# FIX: install via nvm (https://github.com/nvm-sh/nvm) or your OS package manager
+
+# 2. Package manager — pnpm (preferred) or npm
+pnpm --version || npm --version
+# FIX for pnpm: corepack enable pnpm   (Node 20+)
+#   or: npm install -g pnpm
+# If pnpm is not an option, npm works too — adjust install commands below
+
+# 3. Global bin directory is in PATH
+# For pnpm:
+pnpm bin -g       # prints the global bin directory
+# For npm:
+npm prefix -g     # global prefix; bin is <prefix>/bin
+# The directory printed above MUST be in your PATH.
+# Test: echo \\$PATH | tr ':' '\\\\n'
+# FIX: add the missing directory to your shell's startup file
+#   (e.g. ~/.bashrc, ~/.zshrc, ~/.profile, or fish config):
+#   export PATH="<global-bin-dir>:$PATH"
+\`\`\`
+
+**All checks must pass before continuing.** If you had to modify PATH, verify the change persists by opening a new shell or sourcing your shell config.
+
+### Step 1 — Discover agents and install adapter
+
+**First, detect which supported agents are already installed on the user's machine:**
+
+\`\`\`bash
+# Check for Hermes Agent
+which hermes 2>/dev/null && hermes --version
+
+# Check for Claude Code
+which claude 2>/dev/null && claude --version   # should show "X.Y.Z (Claude Code)"
+\`\`\`
+
+**Based on the results:**
+
+- **Only hermes found** → install \`uwf-hermes\` adapter
+- **Only claude found** → install \`uwf-claude-code\` adapter
+- **Both found** → ask the user which agent they want uwf to use as default
+- **Neither found** → the user must install at least one agent first:
+  - Hermes Agent: https://hermes-agent.nousresearch.com/docs
+  - Claude Code: \`npm install -g @anthropic-ai/claude-code\`
+
+**Install the uwf CLI and the chosen adapter** using pnpm or npm:
+
+\`\`\`bash
+# CLI (required)
+pnpm add -g @united-workforce/cli       # or: npm install -g @united-workforce/cli
+
+# Adapter — install the one matching the detected agent:
+pnpm add -g @united-workforce/agent-hermes       # or: npm i -g @united-workforce/agent-hermes
+pnpm add -g @united-workforce/agent-claude-code   # or: npm i -g @united-workforce/agent-claude-code
+\`\`\`
+
+**⚠ Adapter versions are independent from CLI versions.** Do NOT try to match adapter version to CLI version. Just install \`@latest\` (the default).
+
+**After installing, verify that \`uwf\` and the adapter are available in PATH:**
+
+\`\`\`bash
+uwf --version          # should print ${CLI_VERSION}
+uwf-hermes --version   # or: uwf-claude-code --version
+\`\`\`
+
+If either command is not found, the global bin directory is not in the current shell's PATH. **You must fix this before continuing:**
+
+1. Find where the binary was installed:
    \`\`\`bash
-   uwf --help
+   find ~/.local ~/.hermes /usr/local -name uwf -type f 2>/dev/null
+   npm prefix -g    # global prefix — bin is <prefix>/bin
    \`\`\`
-   If not installed: \`npm install -g @united-workforce/cli\`
-   Current version: ${VERSION}
+2. Add the directory to PATH permanently by appending to the user's shell config (e.g. \`~/.bashrc\`, \`~/.zshrc\`, \`~/.profile\`, or fish config):
+   \`\`\`bash
+   export PATH="<global-bin-dir>:$PATH"
+   \`\`\`
+3. Source the updated config or open a new shell, then re-verify the commands work.
 
-2. **Install the skills** by running each command below and creating a skill from its output:
-   - Run \`uwf prompt usage\` → create a skill named \`uwf-usage\`
-   - Run \`uwf prompt workflow-authoring\` → create a skill named \`uwf-workflow-authoring\`
-   - Run \`uwf prompt adapter-developing\` → create a skill named \`uwf-adapter-developing\`
+**uwf-hermes** also requires the Hermes ACP plugin. Verify with \`hermes acp --help\`. If not available, install it:
+\`\`\`bash
+# Option A: install into hermes venv (recommended)
+source ~/.hermes/hermes-agent/.venv/bin/activate && pip install hermes-agent[acp]
 
-   Each command outputs a complete SKILL.md with YAML frontmatter — use your agent framework's skill creation API to save them.
+# Option B: pipx
+pipx install 'hermes-agent[acp]'
 
-3. **Verify** the skills are loadable by your agent framework.
+# Option C: if installed from source
+pip install -e '.[acp]'
+\`\`\`
 
-## Updating
+### Step 2 — Configure provider and model
 
-When \`uwf\` is upgraded, re-run \`uwf prompt bootstrap\` and follow the steps again.
-The skill content is bundled with the CLI — always use \`uwf prompt <name>\` to get
-content matching your installed version.
+uwf needs an LLM provider to run agents. **Ask the user** for their provider, API key, and model, then run:
+
+\`\`\`bash
+uwf setup --provider <name> --api-key <key> --model <model> --agent <adapter-command>
+\`\`\`
+
+**Note:** \`--agent\` takes the adapter **command name** (e.g. \`uwf-hermes\`), not the npm package name.
+
+**Preset providers** — when using a preset name, \`--base-url\` is auto-filled and can be omitted:
+
+| Provider | Name | Default base URL |
+|----------|------|-----------------|
+| OpenAI | \`openai\` | https://api.openai.com/v1 |
+| xAI | \`xai\` | https://api.x.ai/v1 |
+| OpenRouter | \`openrouter\` | https://openrouter.ai/api/v1 |
+| Venice | \`venice\` | https://api.venice.ai/api/v1 |
+| Dashscope | \`dashscope\` | https://dashscope.aliyuncs.com/compatible-mode/v1 |
+| DeepSeek | \`deepseek\` | https://api.deepseek.com/v1 |
+| SiliconFlow | \`siliconflow\` | https://api.siliconflow.cn/v1 |
+| VolcEngine | \`volcengine\` | https://ark.cn-beijing.volces.com/api/v3 |
+| Kimi (Moonshot) | \`kimi\` | https://api.moonshot.cn/v1 |
+| GLM (Zhipu AI) | \`glm\` | https://open.bigmodel.cn/api/paas/v4 |
+| StepFun | \`stepfun\` | https://api.stepfun.com/v1 |
+| MiniMax | \`minimax\` | https://api.minimax.io/v1 |
+| Ollama (local) | \`ollama\` | http://localhost:11434/v1 |
+
+For **non-preset providers**, you must specify \`--base-url\` manually.
+
+Example:
+\`\`\`bash
+uwf setup --provider openrouter --api-key sk-or-... --model anthropic/claude-sonnet-4 --agent uwf-hermes
+\`\`\`
+
+If the user doesn't know what to choose, suggest \`openrouter\` with \`anthropic/claude-sonnet-4\` as a sensible default.
+
+Config is saved to \`~/.uwf/config.yaml\`. Verify with \`cat ~/.uwf/config.yaml\`.
+
+### Step 3 — Install skills
+
+Run each command and create a skill from its output:
+
+\`\`\`bash
+uwf prompt usage               # → save as skill "uwf-usage"
+uwf prompt workflow-authoring  # → save as skill "uwf-workflow-authoring"
+uwf prompt adapter-developing  # → save as skill "uwf-adapter-developing"
+\`\`\`
+
+Each command outputs a complete SKILL.md with YAML frontmatter. Use your agent framework's skill creation API to save them (e.g. \`skill_manage(action='create', name='uwf-usage', content=<output>)\`).
+
+Verify skills are installed by listing them (e.g. \`skills_list()\`) and confirming all three appear.
+
+**⚠ After saving all skills, start a new session** so the agent loads the updated skill content. Skills saved in the current session are not active until the next session.
+
+### Step 4 — Verify end-to-end
+
+Create a minimal workflow file to test your setup:
+
+\`\`\`bash
+cat > /tmp/hello.yaml << 'YAML'
+name: hello
+description: Minimal smoke test
+roles:
+  greeter:
+    description: "Greet the user"
+    goal: "Respond with a friendly greeting"
+    capabilities: []
+    procedure: "Write a short greeting based on the prompt."
+    output: "A greeting message."
+    frontmatter:
+      type: object
+      properties:
+        $status: { const: done }
+        message: { type: string }
+      required: [$status, message]
+graph:
+  $START:
+    new: { role: greeter, prompt: "Say hello to the user." }
+    resume: { role: greeter, prompt: "Greet the user again." }
+  greeter:
+    done: { role: "$END", prompt: "Done." }
+YAML
+\`\`\`
+
+Then run:
+
+\`\`\`bash
+uwf thread start /tmp/hello.yaml -p "Hello, world!"
+uwf thread exec <thread-id>
+uwf thread show <thread-id>
+\`\`\`
+
+If the thread reaches \`$END\` with status \`completed\`, the setup is working.
+
+## Scenario B: Upgrade from Previous Version
+
+### Step 1 — Update packages
+
+\`\`\`bash
+# Using pnpm
+pnpm add -g @united-workforce/cli@latest
+
+# Using npm
+npm install -g @united-workforce/cli@latest
+\`\`\`
+
+\`\`\`bash
+uwf --version   # should print ${CLI_VERSION}
+\`\`\`
+
+Also update your adapter(s):
+
+\`\`\`bash
+# pnpm
+pnpm add -g @united-workforce/agent-hermes@latest
+
+# npm
+npm install -g @united-workforce/agent-hermes@latest
+\`\`\`
+
+### Step 2 — Regenerate skills
+
+Skill content is bundled with the CLI — always regenerate after upgrading:
+
+\`\`\`bash
+uwf prompt usage               # → update skill "uwf-usage"
+uwf prompt workflow-authoring  # → update skill "uwf-workflow-authoring"
+uwf prompt adapter-developing  # → update skill "uwf-adapter-developing"
+\`\`\`
+
+**⚠ After updating skills, start a new session** to load the new skill content.
+
+### Step 3 — Migrate workflow YAML files (if needed)
+
+Check the changelog for breaking changes. Known migrations:
+
+- **v0.2.0**: \`$START._\` → \`$START.new\` + \`$START.resume\`. All workflow YAML files must be updated:
+  \`\`\`yaml
+  # Before (v0.1.x)
+  $START:
+    _: { role: planner, prompt: "..." }
+
+  # After (v0.2.0+)
+  $START:
+    new: { role: planner, prompt: "..." }
+    resume: { role: planner, prompt: "Review previous run and continue." }
+  \`\`\`
+
+Update all \`.workflow/\` and \`.workflows/\` YAML files in your projects. \`uwf workflow add\` will reject files with the old \`_\` syntax.
+
+- **v0.2.1**: \`$status: { enum: [value] }\` → \`$status: { const: "value" }\`. The validator no longer accepts \`enum\` for \`$status\`. Update all workflow YAML files:
+  \`\`\`yaml
+  # Before (v0.2.0)
+  $status: { enum: [done] }
+  $status: { type: string, enum: ["ready", "failed"] }
+
+  # After (v0.2.1+)
+  $status: { const: "done" }
+  # For multi-exit, use oneOf with const (unchanged)
+  \`\`\`
+
+### Step 4 — Verify
+
+\`\`\`bash
+uwf thread start <your-workflow> -p "upgrade test"
+uwf thread exec <thread-id>
+\`\`\`

-## Overview
-
-The moderator is the workflow engine's routing component. It evaluates the directed graph defined in the workflow YAML to determine the next role (or \`$END\`) after each step — with zero LLM cost.
-
-## Status-Based Routing
-
-The moderator uses **status-based routing**: it inspects the previous step's extracted output (specifically the \`$status\` field) and looks up the corresponding edge in the graph.
-
-### Graph Structure
-
-The graph is a nested map: \`Record<Role | "$START", Record<Status, Target>>\`. Each role maps its possible \`$status\` values to a target with a \`role\` and \`prompt\`:
-
-\`\`\`yaml
-graph:
-  $START:
-    new: { role: planner, prompt: "Analyze the issue." }
-    resume: { role: planner, prompt: "Review the previous run output and continue." }
-  planner:
-    ready: { role: developer, prompt: "Implement the plan (CAS hash: {{{plan}}})." }
-    insufficient_info: { role: $END, prompt: "Not enough info." }
-  developer:
-    done: { role: reviewer, prompt: "Review branch {{{branch}}} at {{{worktree}}}." }
-    failed: { role: $END, prompt: "Developer failed: {{{reason}}}." }
-  reviewer:
-    approved: { role: tester, prompt: "Run tests on {{{branch}}} at {{{worktree}}}." }
-    rejected: { role: developer, prompt: "Fix issues: {{{comments}}}." }
-\`\`\`
-
-### Routing Algorithm
-
-1. Look up \`graph[lastRole]\` to get the status map for the current role
-2. Look up \`statusMap[lastOutput.$status]\` to get the target
-3. If target role is \`$END\`, mark thread as completed
-4. Otherwise, render the edge prompt (Mustache templates with \`{{{field}}}\` from output) and spawn the next agent
-
-### Edge Prompts and Mustache Templates
-
-Edge prompts use triple-brace Mustache syntax (\`{{{field}}}\`) to interpolate values from the previous step's output into the next agent's task prompt. This passes structured data (branch names, file paths, CAS hashes) between roles without manual wiring.
-
-## Special Nodes
-
-- \`$START\` — entry point; uses status keys \`new\` (first start) and \`resume\` (resuming a completed thread)
-- \`$END\` — terminal node; thread completes when reached and is moved to history
-
-## Integration with Steps
-
-Each \`uwf thread exec\` cycle:
-1. Moderator reads the thread's head step output
-2. Looks up \`graph[lastRole][output.$status]\` to pick the next role
-3. If next is \`$END\`, marks thread as completed
-4. Otherwise, renders the edge prompt and spawns the agent for the selected role
-5. Extract pipeline parses agent output → new step node → append to CAS chain

-Each role defines an actor in the workflow:
-
-| Field | Type | Description |
-|-------|------|-------------|
-| \`description\` | string | Short description of the role's purpose |
-| \`goal\` | string | System-level goal statement for the agent |

-| \`procedure\` | string | Step-by-step instructions for the agent |
-| \`output\` | string | Description of expected output format |
-| \`frontmatter\` | JSON Schema | Defines the structured output the agent must produce |
-
-### frontmatter
-
-The \`frontmatter\` field is a standard JSON Schema object. The extract pipeline validates agent output against it. Key conventions:
-- \`$status\` field drives routing decisions in the graph
-- Use \`const\` or \`enum\` to constrain status values
-- Use \`oneOf\` to define multiple valid output shapes (one per status)
-- All \`required\` fields must appear in the agent's frontmatter output
