+fix: improve bootstrap docs — agent discovery, pnpm/npm parity, preset provider table (#118, #120)
+
+- Step 1: detect installed agents (hermes/claude) before choosing adapter
+- Step 1: clarify adapter versions are independent from CLI — install @latest
+- Step 1: show pnpm and npm side-by-side
+- Step 1: add "adapter must be installed before `uwf setup --agent`" note
+- Step 1: add ACP verification step (hermes acp --help)
+- Step 2: `--agent` takes adapter command name (e.g. `uwf-hermes`), not npm package
+- Step 2: preset providers listed as a table with names and default base URLs
+- Remove uwf-builtin from supported adapters (not ready yet)

+fix: unify $status to const-only, drop enum support (#123)
+
+Breaking: `$status` in frontmatter now requires `const` everywhere.
+`enum` is no longer accepted and will be rejected by the validator.
+
+- Validator: `hasStatusConst()` / `getConstStatuses()` replace enum-based checks
+- Error message: "must define $status as const (or oneOf with const)"
+- workflow-authoring docs: all examples use `const`, enum explicitly noted as unsupported
+- bootstrap hello.yaml: `$status: { const: done }`
+- All test fixtures migrated from enum to const/oneOf

+  - 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:

+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> --base-url <url> --api-key <key> --model <model> [--agent <adapter>]
+uwf setup --provider <name> --api-key <key> --model <model> --agent <adapter-command>
 \`\`\`
 
-Preset providers (base-url is auto-filled when using a preset name):
-openai, xai, openrouter, venice, dashscope, deepseek, siliconflow, volcengine, kimi, glm, stepfun, minimax, ollama
+**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.
