+feat: replace $START `_` status with `new`/`resume` semantics
+
+BREAKING: All workflow YAML files must update `$START._` to `$START.new` + `$START.resume`.
+The `resume` edge prompt replaces the previously hardcoded resume message in the CLI.

-      You are an experienced scholar arguing FOR the proposition.
+      1. If this is the opening, present your strongest argument against the proposition.
-

-Set up or upgrade uwf (United Workforce) — from zero to running your first workflow.
+Install or update the uwf (United Workforce) skills for your agent.
 
-## Scenario A: Fresh Install
+## Steps
-
-### Step 0 — Environment pre-flight check
-
-Run ALL checks below BEFORE installing anything. If any check fails, fix it first — do NOT skip ahead.
 
+1. **Check if uwf CLI is installed:**
    \`\`\`bash
-# 1. Node.js
+   uwf --help
-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"
    \`\`\`
+   If not installed: \`npm install -g @united-workforce/cli\`
+   Current version: ${VERSION}
 
-**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.
+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\`
 
-### Step 1 — Discover agents and install adapter
+   Each command outputs a complete SKILL.md with YAML frontmatter — use your agent framework's skill creation API to save them.
 
-**First, detect which supported agents are already installed on the user's machine:**
+3. **Verify** the skills are loadable by your agent framework.
 
-\`\`\`bash
+## Updating
-# Check for Hermes Agent
-which hermes 2>/dev/null && hermes --version
 
-# Check for Claude Code
+When \`uwf\` is upgraded, re-run \`uwf prompt bootstrap\` and follow the steps again.
-which claude 2>/dev/null && claude --version   # should show "X.Y.Z (Claude Code)"
+The skill content is bundled with the CLI — always use \`uwf prompt <name>\` to get
-\`\`\`
+content matching your installed version.
-
-**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 ${CLI_VERSION}
-uwf-hermes --version   # or: uwf-claude-code --version
-\`\`\`
-
-If either command is not found, the global bin directory is not in the current shell's PATH. **You must fix this before continuing:**
-
-1. Find where the binary was installed:
-   \`\`\`bash
-   find ~/.local ~/.hermes /usr/local -name uwf -type f 2>/dev/null
-   npm prefix -g    # global prefix — bin is <prefix>/bin
-   \`\`\`
-2. Add the directory to PATH permanently by appending to the user's shell config (e.g. \`~/.bashrc\`, \`~/.zshrc\`, \`~/.profile\`, or fish config):
-   \`\`\`bash
-   export PATH="<global-bin-dir>:$PATH"
-   \`\`\`
-3. Source the updated config or open a new shell, then re-verify the commands work.
-
-**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]
-
-# Option B: pipx
-pipx install 'hermes-agent[acp]'
-
-# Option C: if installed from source
-pip install -e '.[acp]'
-\`\`\`
-
-### Step 2 — Configure provider and model
-
-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
