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. 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 | 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 `$END`. Each step is a complete process: the moderator evaluates JSONata conditions to pick the next role, an external agent CLI produces frontmatter markdown output, and an extract pipeline validates or structures that output against the role's JSON Schema.
|---------|-----|------|
| `cli-workflow` | `@uncaged/cli-workflow` | `uwf` CLI binary — thread lifecycle, workflow registry, CAS inspection, setup |
| `workflow-protocol` | `@uncaged/workflow-protocol` | Shared TypeScript types (`WorkflowPayload`, `StepNodePayload`, `WorkflowConfig`, etc.) |
| `workflow-moderator` | `@uncaged/workflow-moderator` | JSONata graph evaluator — determines next role or `$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 |
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).
See [docs/architecture.md](docs/architecture.md) for the full design — three-phase engine loop, CAS node types, storage layout, agent CLI protocol, and design decisions.

# @uncaged/workflow-agent-builtin
`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

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`.

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> };

# @uncaged/workflow-agent-claude-code
`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`
## Installation
Included as the `uwf-claude-code` binary when you install `@uncaged/workflow-agent-claude-code`:
```bash
bun add -g @uncaged/workflow-agent-claude-code
```
Requires the `claude` CLI on `PATH`.
## CLI Usage
Invoked by `uwf thread step`:
```bash
uwf-claude-code <thread-id> <role>
```
Configure or override the agent:
```bash
uwf setup --agent claude-code
uwf thread step <thread-id> --agent uwf-claude-code
```
Environment variables set by the engine:

function buildClaudeCodePrompt(ctx: AgentContext): string
```
### Session detail
```typescript
function parseClaudeCodeStreamOutput(stdout: string): ClaudeCodeParsedResult | null
function parseClaudeCodeJsonOutput(stdout: string): ClaudeCodeParsedResult | null
function storeClaudeCodeDetail(
store: Store,
parsed: ClaudeCodeParsedResult,
sessionId: string,
): Promise<string>
function storeClaudeCodeRawOutput(store: Store, rawOutput: string): Promise<string>
```
## Usage (library)
```typescript
import { createClaudeCodeAgent, buildClaudeCodePrompt } from "@uncaged/workflow-agent-claude-code";
const main = createClaudeCodeAgent();
void main();

# @uncaged/workflow-agent-hermes
`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:

# @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";

# @uncaged/workflow-dashboard
Web graph editor for visualizing and editing workflow YAML definitions.
## Overview
A private alpha web app (not part of the runtime engine stack). Provides a React + `@xyflow/react` canvas for editing workflow roles, conditions, and graph transitions. Uses `@uncaged/workflow-protocol` types for validation and YAML round-tripping.
Planned integration: local `uwf connect` over WebSocket to sync YAML between CLI and the browser editor. The REST API and Elysia backend are currently stubs for development.
**Dependencies:** `@uncaged/workflow-protocol`, `@xyflow/react`, React 19, react-router v7, Vite 8, Tailwind CSS v4, Elysia
## Installation
Monorepo-only ( `"private": true` ). Not published to npm.
```bash
cd packages/workflow-dashboard
bun install --no-cache
```
## CLI Usage
Start the Vite dev server (port 3000):
```bash
cd packages/workflow-dashboard
bun run dev
```
Build for production:
```bash
bun run build
```
Open `http://localhost:3000` in a browser.

# @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}`);
}

# @uncaged/workflow-protocol
Shared TypeScript types and JSON Schema constants for the workflow engine.
## Overview
This is the contract layer (Layer 0). It defines `WorkflowPayload`, thread node payloads, moderator context, CLI output shapes, and configuration types used across every other package. It has no runtime logic beyond exporting schema objects from `@uncaged/json-cas`.
**Dependencies:** `@uncaged/json-cas`, `@uncaged/json-cas-fs`
## Installation
```bash
bun add @uncaged/workflow-protocol
```
## API
All exports come from `src/index.ts`.

# @uncaged/workflow-util # @uncaged/workflow-util
Shared utilities: encoding, IDs, logging, storage paths, and ref-field normalization. Shared utilities: encoding, IDs, logging, frontmatter parsing, storage paths, and CLI reference generation.
## What This Package Does ## Overview
It provides filesystem-safe Base32 and ULID generation, the structured logger used across packages, helpers for the default workflow data directory and global CAS path, and utilities to merge/normalize `refs` on steps. It re-exports `ok`/`err` from protocol for convenience. Layer 1 shared infrastructure used across CLI, agent-kit, and agent packages. Provides Crockford Base32 encoding, ULID generation, structured logging with fixed 8-char tags, frontmatter markdown parsing/validation, process-level debug logging, and helpers for the default workflow data directory.

- **Base32:** `CROCKFORD_BASE32_ALPHABET`, `decodeCrockfordBase32Bits`, `decodeCrockfordToUint64`, `encodeCrockfordBase32Bits`, `encodeUint64AsCrockford` ```bash
- **Logger:** `createLogger` bun add @uncaged/workflow-util
- **Refs:** `mergeRefsWithContentHash`, `normalizeRefsField` ```
- **Result:** `ok`, `err` (from `@uncaged/workflow-protocol`)
- **Paths:** `getDefaultWorkflowStorageRoot`, `getGlobalCasDir`
- **ULID:** `generateUlid`
- **Types:** `CreateLoggerOptions`, `LogFn`, `LoggerSink`, `Result`
