 A stateless workflow engine driven by a single-step CLI. Workflows are YAML definitions with roles, JSONata routing conditions, and a directed graph. Threads are immutable CAS-linked chains — each `uwf thread step` runs one moderator→agent→extract cycle and exits.
 
-## Package Map
+## Overview
 
-| Package | npm | Role |
-|---------|-----|------|
-| `cli-workflow` | `@uncaged/cli-workflow` | `uwf` CLI binary — thread lifecycle, workflow registry, CAS inspection, setup |
-| `workflow-protocol` | `@uncaged/workflow-protocol` | Shared TypeScript types (`WorkflowPayload`, `StepNodePayload`, `WorkflowConfig`, etc.) |
-| `workflow-moderator` | `@uncaged/workflow-moderator` | JSONata graph evaluator — determines next role or `$END` |
-| `workflow-agent-kit` | `@uncaged/workflow-agent-kit` | `createAgent` factory, context builder, two-layer extract pipeline |
-| `workflow-agent-hermes` | `@uncaged/workflow-agent-hermes` | `uwf-hermes` agent — spawns Hermes chat, captures session |
-| `workflow-util` | `@uncaged/workflow-util` | Crockford Base32, ULID, logger, frontmatter parsing |
+This monorepo implements **uwf**, a workflow engine with no long-running daemon. You register YAML workflow definitions in a content-addressed store (CAS), start a thread with an initial prompt, then invoke `uwf thread step` repeatedly until the moderator routes to `$END`. Each step is a complete process: the moderator evaluates JSONata conditions to pick the next role, an external agent CLI produces frontmatter markdown output, and an extract pipeline validates or structures that output against the role's JSON Schema.
 
-External: [`@uncaged/json-cas`](https://www.npmjs.com/package/@uncaged/json-cas) (CAS store + JSON Schema validation) + `@uncaged/json-cas-fs` (filesystem backend).
+Workflow state lives entirely on disk under `~/.uncaged/workflow/`: CAS nodes for definitions and step payloads, `registry.yaml` for workflow name→hash mappings, and `threads.yaml` for active thread head pointers. Completed threads are archived to `history.jsonl`. Because there is no server process, workflows are easy to debug, fork, and inspect with ordinary CLI tools.
+
+Agents are pluggable CLI binaries (`uwf-hermes`, `uwf-builtin`, `uwf-claude-code`, or custom commands). The engine spawns the configured agent with `<thread-id>` and `<role>`, sets `UWF_EDGE_PROMPT` from the graph transition, and captures both the agent's markdown output and a detail CAS node for session replay.
+
+## Architecture
+
+Dependency layers (lower layers have no dependency on higher layers):
+
+```
+Layer 0 — Contract
+  workflow-protocol          Shared types and JSON Schema definitions
+
+Layer 1 — Shared infra
+  workflow-util              Encoding, IDs, logging, frontmatter, paths
+  workflow-moderator         JSONata graph evaluator
+
+Layer 2 — Agent framework
+  workflow-agent-kit         createAgent factory, context builder, extract pipeline
+
+Layer 3 — Agent implementations
+  workflow-agent-hermes      Hermes ACP agent (uwf-hermes)
+  workflow-agent-builtin     Built-in LLM + tools agent (uwf-builtin)
+  workflow-agent-claude-code Claude Code agent (uwf-claude-code)
+
+Layer 4 — CLI
+  cli-workflow               uwf binary — thread lifecycle, registry, CAS, setup
+
+App (uses protocol; not in the runtime engine stack)
+  workflow-dashboard         Web UI for visual workflow editing
+```
+
+External CAS: [`@uncaged/json-cas`](https://www.npmjs.com/package/@uncaged/json-cas) (store API, hashing, schema validation) + `@uncaged/json-cas-fs` (filesystem backend).

+`uwf` CLI — thread lifecycle, workflow registry, CAS inspection, and setup.
+
+## Overview
+
+Layer 4 entry point for the workflow engine. The `uwf` binary orchestrates one step per invocation: load thread head from `threads.yaml`, run the moderator, spawn the configured agent CLI, run extract, append a CAS step node, and update the head pointer (or archive when `$END`).
+
+This package has no library `src/index.ts` — it is consumed as a CLI binary only.
+
+**Dependencies:** `@uncaged/json-cas`, `@uncaged/json-cas-fs`, `@uncaged/workflow-agent-kit`, `@uncaged/workflow-moderator`, `@uncaged/workflow-protocol`, `@uncaged/workflow-util`, `commander`, `dotenv`, `yaml`
+
+## Installation
+
+Included as the `uwf` binary when you install `@uncaged/cli-workflow`:
+
+```bash
+bun add -g @uncaged/cli-workflow
+# or from the monorepo:
+bun link packages/cli-workflow
+```
+
+## CLI Usage
+
+### Global options

+
+`uwf-builtin` agent — built-in LLM agent with file read/write and shell tools.
+
+## Overview
+
+Layer 3 agent implementation. Runs an OpenAI-compatible chat completion loop with built-in tools (`read_file`, `write_file`, `run_command`). Uses the configured provider/model from `config.yaml`. Produces frontmatter markdown output and stores turn-by-turn session detail in CAS.
+
+Useful when you want a self-contained agent without an external CLI like Hermes or Claude Code.
+
+**Dependencies:** `@uncaged/json-cas`, `@uncaged/workflow-agent-kit`, `@uncaged/workflow-util`
+
+## Installation
+
+Included as the `uwf-builtin` binary when you install `@uncaged/workflow-agent-builtin`:
+
+```bash
+bun add -g @uncaged/workflow-agent-builtin
+```
+
+## CLI Usage
+
+Invoked by `uwf thread step`:
+
+```bash
+uwf-builtin <thread-id> <role>
+```
+
+Configure as default agent:
+
+```bash
+uwf setup --agent builtin
+```
+
+Override per step:
+
+```bash
+uwf thread step <thread-id> --agent uwf-builtin
+```
+
+Environment variables set by the engine:
+
+| Variable | Purpose |
+|----------|---------|
+| `UWF_EDGE_PROMPT` | Moderator edge instruction for this step |
+
+## API
+
+All exports come from `src/index.ts`.
+
+### Agent factory
+
+```typescript
+function createBuiltinAgent(): () => Promise<void>
+function buildBuiltinMessages(ctx: AgentContext): ChatMessage[]
+```
+
+### LLM loop
+
+```typescript
+const BUILTIN_MAX_TURNS = 30;
+const BUILTIN_CONTINUE_MAX_TURNS = 5;
+
+function runBuiltinLoop(/* options: RunBuiltinLoopOptions */): Promise<RunBuiltinLoopResult>
+function chatCompletionWithTools(
+  provider: ResolvedLlmProvider,
+  messages: ChatMessage[],
+  tools: OpenAiToolDefinition[],
+): Promise<LlmAssistantResponse>
+```
+
+`RunBuiltinLoopOptions` and `RunBuiltinLoopResult` are internal to `loop.ts` and not re-exported from `index.ts`.
+
+### Tools
+
+```typescript
+function getBuiltinTools(): readonly BuiltinTool[]
+function executeBuiltinTool(
+  name: string,
+  args: Record<string, unknown>,
+  ctx: ToolContext,
+): Promise<string>
+```
+
+### Session and detail
+
+```typescript
+function initSessionDir(storageRoot: string): Promise<void>
+function appendSessionTurn(storageRoot: string, sessionId: string, turn: BuiltinTurnPayload): Promise<void>
+function readSessionTurns(storageRoot: string, sessionId: string): Promise<BuiltinTurnPayload[]>
+function removeSession(storageRoot: string, sessionId: string): Promise<void>
+function registerBuiltinSchemas(store: Store): Promise<BuiltinSchemaHashes>
+function storeBuiltinDetail(store: Store, payload: BuiltinDetailPayload): Promise<string>
+```
+
+### Types
+
+```typescript
+type ChatMessage = /* system | user | assistant | tool */;
+type LlmAssistantResponse = { content: string | null; toolCalls: LlmToolCall[] | null };
+type LlmToolCall = { id: string; name: string; arguments: string };
+type BuiltinTool = { name: string; description: string; parameters: Record<string, unknown> };
+type ToolContext = { cwd: string; storageRoot: string };
+type BuiltinDetailPayload = { /* session turns, model, timestamps */ };
+type BuiltinLoopTurn = { /* single loop iteration record */ };
+type BuiltinToolCallRecord = { /* tool call audit */ };
+type BuiltinToolResultRecord = { /* tool result audit */ };
+type BuiltinTurnPayload = { /* persisted turn */ };
+```

+
+## Configuration
+
+Requires a configured OpenAI-compatible provider and model in `~/.uncaged/workflow/config.yaml` (via `uwf setup`). API keys are loaded from `~/.uncaged/workflow/.env`.
+
+Tools run with the current working directory as `ToolContext.cwd` (typically the directory where `uwf thread step` was invoked).

+`uwf-claude-code` agent — spawns the Claude Code CLI and captures session detail.
+
+## Overview
+
+Layer 3 agent implementation. Spawns the `claude` CLI with a composed system prompt (role definition, task, prior steps, edge prompt). Parses stream or JSON stdout, caches session IDs for multi-turn continuation, and stores raw output plus structured detail in CAS.
+
+**Dependencies:** `@uncaged/json-cas`, `@uncaged/workflow-agent-kit`
+

+
+Requires the `claude` CLI on `PATH`.
+
+## CLI Usage
+
+Invoked by `uwf thread step`:

+
+## API

+
+`uwf-hermes` agent — spawns Hermes chat via ACP and captures session detail.
+
+## Overview
+
+Layer 3 agent implementation. Wraps the Hermes CLI using the Agent Client Protocol (ACP). On first visit to a role it sends a composed prompt (role definition, task, history, edge prompt); on continuation it resumes the cached session. Session transcripts and raw output are stored as CAS detail nodes.
+
+**Dependencies:** `@uncaged/json-cas`, `@uncaged/workflow-agent-kit`, `@uncaged/workflow-protocol`, `@uncaged/workflow-util`
+
+## Installation
+
+Included as the `uwf-hermes` binary when you install `@uncaged/workflow-agent-hermes`:
+
+```bash
+bun add -g @uncaged/workflow-agent-hermes
+```
+
+Requires the `hermes` CLI on `PATH`.
+
+## CLI Usage
+
+Invoked by `uwf thread step` (not typically run directly):
+
+```bash
+uwf-hermes <thread-id> <role>
+```
+
+Environment variables set by the engine:
+
+| Variable | Purpose |
+|----------|---------|
+| `UWF_EDGE_PROMPT` | Moderator edge instruction for this step |
+
+Configure as the default agent via `uwf setup --agent hermes`.
+
+Override per step:
+
+```bash
+uwf thread step <thread-id> --agent uwf-hermes
+```
+
+## API
+
+All exports come from `src/index.ts`.
+
+### Agent factory
+
+```typescript
+function createHermesAgent(): () => Promise<void>
+function buildHermesPrompt(ctx: AgentContext): string
+```
+
+### ACP client
+
+```typescript
+class HermesAcpClient {
+  // Spawns hermes, handles JSON-RPC over stdio
+}
+```
+
+## Usage (library)
+
+```typescript
+import { createHermesAgent, buildHermesPrompt } from "@uncaged/workflow-agent-hermes";

+const main = createHermesAgent();

+# @uncaged/workflow-agent-kit
+
+Agent framework — `createAgent` factory, context builder, frontmatter fast-path, and LLM extract pipeline.
+
+## Overview
+
+Layer 2 agent framework. Provides the standard entrypoint for all agent CLIs: parse `<thread-id> <role>` from argv, load thread/workflow context from CAS, invoke the agent's `run`/`continue` functions, validate output via frontmatter fast-path or LLM extract, and write a `StepNodePayload` to CAS.
+
+Also exports prompt builders, config/storage helpers, and session ID caching for multi-turn agents.
+
+**Dependencies:** `@uncaged/json-cas`, `@uncaged/json-cas-fs`, `@uncaged/workflow-protocol`, `@uncaged/workflow-util`, `dotenv`, `yaml`
+
+## Installation
+
+```bash
+bun add @uncaged/workflow-agent-kit
+```
+
+## API
+
+All exports come from `src/index.ts`.
+
+### Agent factory
+
+```typescript
+function createAgent(options: AgentOptions): () => Promise<void>
+
+type AgentOptions = {
+  name: string;
+  run: AgentRunFn;
+  continue: AgentContinueFn;
+};
+
+type AgentRunFn = (ctx: AgentContext) => Promise<AgentRunResult>;
+type AgentContinueFn = (
+  sessionId: string,
+  message: string,
+  store: AgentContext["store"],
+) => Promise<AgentRunResult>;
+
+type AgentRunResult = {
+  output: string;
+  detailHash: string;
+  sessionId: string;
+};
+```
+
+Agent CLIs call `createAgent(...)` and invoke the returned function as `main()`.
+
+### Context
+
+```typescript
+function buildContext(threadId: ThreadId, role: string): Promise<AgentContext>
+function buildContextWithMeta(
+  threadId: ThreadId,
+  role: string,
+): Promise<AgentContext & { meta: BuildContextMeta }>
+
+type AgentContext = ModeratorContext & {
+  threadId: ThreadId;
+  role: string;
+  store: Store;
+  workflow: WorkflowPayload;
+  outputFormatInstruction: string;
+  edgePrompt: string;
+  isFirstVisit: boolean;
+};
+
+type BuildContextMeta = {
+  storageRoot: string;
+  store: Store;
+  schemas: AgentStore["schemas"];
+  headHash: CasRef;
+  chain: ChainState;
+};
+```
+
+Requires `UWF_EDGE_PROMPT` in the environment (set by `uwf thread step`).
+
+### Prompt builders
+
+```typescript
+function buildRolePrompt(role: RoleDefinition): string
+function buildOutputFormatInstruction(schema: JSONSchema): string
+function buildContinuationPrompt(
+  ctx: AgentContext,
+  priorOutput: string,
+  instruction: string,
+): string
+```
+
+### Extract pipeline
+
+```typescript
+function resolveExtractModelAlias(config: WorkflowConfig): ModelAlias
+function resolveModel(config: WorkflowConfig, alias: ModelAlias): ResolvedLlmProvider
+function extract(
+  rawOutput: string,
+  outputSchema: CasRef,
+  config: WorkflowConfig,
+): Promise<ExtractResult>
+
+type ResolvedLlmProvider = { baseUrl: string; apiKey: string; model: string };
+type ExtractResult = { value: unknown; hash: CasRef };
+```
+
+### Frontmatter fast-path
+
+```typescript
+function tryFrontmatterFastPath(
+  rawOutput: string,
+  outputSchema: CasRef,
+  store: Store,
+): Promise<FrontmatterFastPathResult | null>
+
+type FrontmatterFastPathResult = { body: string; outputHash: CasRef };
+```
+
+### Session cache
+
+```typescript
+function getCachedSessionId(threadId: ThreadId, role: string): Promise<string | null>
+function setCachedSessionId(
+  threadId: ThreadId,
+  role: string,
+  sessionId: string,
+): Promise<void>
+```
+
+### Config and storage
+
+```typescript
+function getConfigPath(storageRoot: string): string
+function getEnvPath(storageRoot: string): string
+function resolveStorageRoot(): string
+function loadWorkflowConfig(storageRoot: string): Promise<WorkflowConfig>
+```
+
+## Usage
+
+```typescript
+import { createAgent, buildRolePrompt } from "@uncaged/workflow-agent-kit";
+import type { AgentContext, AgentRunResult } from "@uncaged/workflow-agent-kit";
+
+async function run(ctx: AgentContext): Promise<AgentRunResult> {
+  const prompt = buildRolePrompt(ctx.workflow.roles[ctx.role]!);
+  // ... spawn external process, capture output ...
+  return { output: markdown, detailHash: "...", sessionId: "..." };
+}
+
+async function continueSession(
+  sessionId: string,
+  message: string,
+): Promise<AgentRunResult> {
+  // ... continue multi-turn session ...
+  return { output: markdown, detailHash: "...", sessionId };
+}

+## Configuration
+
+| Setting | Default | Notes |
+|---------|---------|-------|
+| Dev server port | `3000` | Set in `server.ts` |
+| Workflow storage (dev) | `tmp/workflow/` | YAML files during development |
+| Path alias | `@/` → `src/` | Configured in `vite.config.ts` |
+
+No library API — this package is an application, not importable as a module.

+# @uncaged/workflow-moderator
+
+JSONata-based graph evaluator — determines the next role or `$END` with zero LLM cost.
+
+## Overview
+
+The moderator (Layer 1) walks the workflow graph from the current role. For each outgoing transition it evaluates an optional JSONata condition against `ModeratorContext` (start prompt + prior step outputs). The first truthy transition wins; its target role and edge prompt are returned. When no transition matches, the workflow ends (`$END`).
+
+**Dependencies:** `@uncaged/workflow-protocol`, `jsonata`
+
+## Installation
+
+```bash
+bun add @uncaged/workflow-moderator
+```
+
+## API
+
+### Functions
+
+```typescript
+function evaluate(
+  workflow: WorkflowPayload,
+  context: ModeratorContext,
+): Promise<Result<EvaluateResult, Error>>
+```
+
+Returns `{ ok: true, value: { role, prompt } }` where `role` is the next role name or `"$END"`, and `prompt` is the edge instruction for the agent.
+
+### Types
+
+```typescript
+type EvaluateResult = {
+  role: string;
+  prompt: string;
+};
+```
+
+The `Result<T, E>` type is local to this package (`{ ok: true; value: T } | { ok: false; error: E }`), not re-exported from `index.ts`.
+
+## Usage
+
+```typescript
+import { evaluate } from "@uncaged/workflow-moderator";
+import type { ModeratorContext, WorkflowPayload } from "@uncaged/workflow-protocol";
+
+const result = await evaluate(workflow, context);
+if (result.ok && result.value.role !== "$END") {
+  console.log(`Next role: ${result.value.role}, prompt: ${result.value.prompt}`);
+}
