-# Test Spec: uwf setup model connectivity validation (#335)
-
-## Context
-
-File: `packages/cli-workflow/src/commands/setup.ts`
-Test file: `packages/cli-workflow/src/__tests__/setup-validate.test.ts`
-
-After `cmdSetup` writes config, it should send a test chat completion request to verify the configured model is reachable. If validation fails, warn the user (don't abort — config is already saved).
-
-## Implementation Notes
-
-- Add a `validateModel(baseUrl, apiKey, model)` function that sends a minimal chat completion request (`POST /chat/completions` with `messages: [{role:"user",content:"hi"}]`, `max_tokens: 1`)
-- Returns `Result<void, string>` — ok if 2xx response, error with reason string otherwise
-- Use `AbortSignal.timeout(15_000)` for the request
-- Both `cmdSetup` and `cmdSetupInteractive` should call it after saving config
-- `cmdSetup` returns validation result in its return object: `{ ...existing, validation: { ok: true } | { ok: false, error: string } }`
-- `cmdSetupInteractive` prints a warning to console if validation fails, success message if it passes
-- Use the project logger (`createLogger`) — no raw `console.log` except in interactive CLI output (per CLAUDE.md)
-
-## Test Cases (vitest)
-
-### 1. `validateModel` — success path
-- Mock `fetch` to return `{ status: 200, ok: true, json: () => ({}) }`
-- Call `validateModel(baseUrl, apiKey, model)`
-- Assert returns `{ ok: true, value: undefined }`
-- Assert fetch was called with correct URL (`${baseUrl}/chat/completions`), correct headers (`Authorization: Bearer ${apiKey}`), correct body (model, messages, max_tokens: 1)
-
-### 2. `validateModel` — HTTP error (401 unauthorized)
-- Mock `fetch` to return `{ status: 401, ok: false, statusText: "Unauthorized" }`
-- Call `validateModel(baseUrl, apiKey, model)`
-- Assert returns `{ ok: false, error: <string containing "401"> }`
-
-### 3. `validateModel` — HTTP error (404 model not found)
-- Mock `fetch` to return `{ status: 404, ok: false, statusText: "Not Found" }`
-- Assert returns `{ ok: false, error: <string containing "404"> }`
-
-### 4. `validateModel` — network timeout
-- Mock `fetch` to throw `DOMException` with name `AbortError`
-- Assert returns `{ ok: false, error: <string containing "timeout" or "unreachable"> }`
-
-### 5. `validateModel` — network error (DNS failure, connection refused)
-- Mock `fetch` to throw `TypeError("fetch failed")`
-- Assert returns `{ ok: false, error: <string mentioning connectivity> }`
-
-### 6. `cmdSetup` — includes validation result on success
-- Mock global `fetch` for `/chat/completions` to succeed
-- Call `cmdSetup({ provider, baseUrl, apiKey, model, storageRoot })`
-- Assert returned object has `validation: { ok: true, value: undefined }`
-- Assert config files are still written (existing behavior preserved)
-
-### 7. `cmdSetup` — includes validation result on failure (config still saved)
-- Mock global `fetch` for `/chat/completions` to return 401
-- Call `cmdSetup({ ... })`
-- Assert returned object has `validation: { ok: false, error: ... }`
-- Assert `config.yaml` and `.env` are still written (validation failure doesn't prevent saving)
-
-### 8. `cmdSetupInteractive` — prints success message on validation pass
-- Mock `fetch` for both `/models` and `/chat/completions` to succeed
-- Mock stdin to provide valid selections
-- Capture console output
-- Assert output contains a success message like "Model verified" or "✓"
-
-### 9. `cmdSetupInteractive` — prints warning on validation failure
-- Mock `fetch`: `/models` succeeds, `/chat/completions` returns 401
-- Mock stdin for valid selections
-- Capture console output
-- Assert output contains a warning about model not being reachable and suggests trying a different model
-
-### 10. `validateModel` — request body correctness
-- Mock `fetch` to capture the request body
-- Call `validateModel(baseUrl, apiKey, "test-model")`
-- Assert body is `{ model: "test-model", messages: [{role: "user", content: "hi"}], max_tokens: 1 }`
-
-## Export Requirements
-
-- `validateModel` must be exported (for direct unit testing)
-- Signature: `async function validateModel(baseUrl: string, apiKey: string, model: string): Promise<Result<void, string>>`
-- `Result` type: `{ ok: true; value: T } | { ok: false; error: E }` (project convention)
-
-## Files to Create/Modify
-
-- **New**: `packages/cli-workflow/src/__tests__/setup-validate.test.ts` — all test cases above
-- **Modify**: `packages/cli-workflow/src/commands/setup.ts` — add `validateModel`, integrate into `cmdSetup` and `cmdSetupInteractive`

-      2. `uwf config set models.test.name test-model` — set a test key
-      3. `uwf config get models.test.name` — verify it returns "test-model"
-
-      Phase 3 — Workflow registration:
-      4. `uwf workflow add ~/repos/workflow/examples/solve-issue.yaml` — register workflow
-      5. Verify the output contains a hash
-      6. `uwf workflow list` — verify non-empty array

-`uwf-hermes` agent — spawns Hermes chat via ACP and captures session detail.
+`uwf-hermes` — an **agent adapter** that bridges the `uwf` workflow engine and the Hermes CLI.
 
 ## 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.
+`uwf-hermes` is an adapter (not the Hermes CLI itself). The `uwf` engine speaks a generic agent protocol (stdin/stdout frontmatter contract); `uwf-hermes` translates that protocol into Hermes ACP (Agent Client Protocol) calls. Other adapters (e.g. `uwf-claude-code`, `uwf-cursor`) do the same for their respective CLIs.
+
+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.

+You are executing a workflow role. Your system prompt defines your goal, procedure, and output requirements. This reference covers two things you need to know about the workflow engine.
+
+## 1. Frontmatter Output Protocol
+
+Your response **MUST** begin with a YAML frontmatter block at byte position 0 — no preamble text before it.
+
+\`\`\`
+---
+status: done
+myField: some value
+---
+
+... markdown body (your work, explanation, notes) ...
+\`\`\`
+
+### Standard Field
+
+| Field | Values | Default | Description |
+|-------|--------|---------|-------------|
+| \`status\` | \`done\`, \`needs_input\`, \`in_progress\`, \`failed\` | \`done\` | Completion signal — determines which graph edge the moderator follows next |
+
+### Schema-Defined Fields
+
+Your role's output schema (shown in the system prompt under "Deliverable Format") defines additional fields. Output **only** the fields listed there — do not invent extra fields.
+
+### Body
+
+Everything after the closing \`---\` fence is the markdown body. Use it for explanations, logs, or human-readable notes. The body is stored but not parsed by the engine.
+
+### Retry
+
+If the engine cannot parse your frontmatter, it will ask you to retry (up to 2 times). Just output the corrected frontmatter block — don't panic.
+
+## 2. CAS (Content-Addressable Store)
+
+Your frontmatter output is automatically stored in CAS. You can also **use CAS directly** to store intermediate artifacts, build merkle DAGs for large outputs, or reference data from previous steps.
+
+### Commands
+
+\`\`\`
+uwf cas put-text <text>           # store plain text, print hash
+uwf cas put <type-hash> <json>    # store typed JSON data, print hash
+uwf cas get <hash>                # read a CAS node (type + payload)
+uwf cas has <hash>                # check if a hash exists
+uwf cas refs <hash>               # list direct references from a node
+uwf cas walk <hash>               # recursive traversal from a node
+uwf cas schema list               # list registered schemas
+uwf cas schema get <hash>         # show a schema definition
+\`\`\`
+
+### Merkle DAG Pattern
+
+For large outputs, store parts individually and reference their hashes:
+
+\`\`\`bash
+# Store individual sections
+HASH1=$(uwf cas put-text "section 1 content")
+HASH2=$(uwf cas put-text "section 2 content")
+
+# Reference hashes in your frontmatter or in a parent node
+\`\`\`
+
+This enables progressive loading — consumers can fetch the root and resolve children on demand.

+Guide for building a new agent adapter (CLI binary) for the workflow engine.
+
+## What Is an Adapter
+
+An adapter is a CLI command (e.g. \`uwf-hermes\`, \`uwf-builtin\`) that the engine spawns to execute a role. It bridges the workflow engine and an LLM/agent backend. The engine calls it with:
+
+\`\`\`
+uwf-<name> --thread <id> --role <role> --prompt <text>
+\`\`\`
+
+The adapter must produce frontmatter markdown output. The engine handles argument parsing, context building, output extraction, and CAS persistence — you just implement the LLM interaction.
+
+## Quick Start
+
+\`\`\`typescript
+import { createAgent } from "@uncaged/workflow-util-agent";
+import type { AgentContext, AgentRunResult, AgentContinueFn, AgentRunFn } from "@uncaged/workflow-util-agent";
+
+const run: AgentRunFn = async (ctx: AgentContext): Promise<AgentRunResult> => {
+  // 1. Build your prompt from ctx
+  // 2. Call your LLM backend
+  // 3. Return the result
+  return { output: rawMarkdown, detailHash, sessionId };
+};
+
+const continue_: AgentContinueFn = async (sessionId, message, store) => {
+  // Resume an existing session with a correction message
+  return { output: correctedMarkdown, detailHash, sessionId };
+};
+
+const main = createAgent({ name: "my-agent", run, continue: continue_ });
+main();
+\`\`\`
+
+## The \`createAgent\` Factory
+
+\`createAgent(options)\` returns an async \`main()\` function that handles the full lifecycle:
+
+1. Parses CLI args (\`--thread\`, \`--role\`, \`--prompt\`)
+2. Loads \`.env\` from storage root
+3. Builds \`AgentContext\` (thread history, workflow definition, role prompt)
+4. Injects \`outputFormatInstruction\` from the role's frontmatter schema
+5. Calls your \`run(ctx)\` function
+6. Extracts frontmatter from your output via \`tryFrontmatterFastPath()\`
+7. If extraction fails, calls your \`continue(sessionId, correctionMessage, store)\` up to 2 times
+8. Persists the validated output as a CAS step node
+9. Prints the step hash to stdout
+
+You only implement \`run\` and \`continue\`.
+
+## AgentOptions
+
+\`\`\`typescript
+type AgentOptions = {
+  name: string;           // Adapter name (used in step records as "uwf-<name>")
+  run: AgentRunFn;        // Execute a role from scratch
+  continue: AgentContinueFn;  // Resume a session for frontmatter correction
+};
+\`\`\`
+
+## AgentContext
+
+The \`ctx\` object passed to your \`run\` function:
+
+| Field | Type | Description |
+|-------|------|-------------|
+| \`threadId\` | \`string\` | Thread ULID |
+| \`role\` | \`string\` | Role name being executed |
+| \`edgePrompt\` | \`string\` | Moderator's task instruction for this step |
+| \`workflow\` | \`WorkflowPayload\` | Full workflow definition (roles, graph) |
+| \`start\` | \`StartNodePayload\` | Thread start data (workflow hash, user prompt) |
+| \`steps\` | \`StepContext[]\` | Previous steps with expanded outputs |
+| \`store\` | \`Store\` | CAS store for reading/writing data |
+| \`outputFormatInstruction\` | \`string\` | Frontmatter format instruction (inject into system prompt) |
+| \`isFirstVisit\` | \`boolean\` | True if this role hasn't run before in this thread |
+
+## AgentRunResult
+
+Your \`run\` and \`continue\` functions must return:
+
+\`\`\`typescript
+type AgentRunResult = {
+  output: string;       // Raw markdown with frontmatter (must start with ---)
+  detailHash: string;   // CAS hash of session detail (turn history, metadata)
+  sessionId: string;    // Session ID for potential continue() calls
+};
+\`\`\`
+
+## Building the Prompt
+
+Use helpers from \`@uncaged/workflow-util-agent\`:
+
+| Helper | Purpose |
+|--------|---------|
+| \`buildRolePrompt(roleDef)\` | Assemble Goal/Capabilities/Prepare/Procedure/Output sections |
+| \`buildContinuationPrompt(steps, role, edgePrompt)\` | For re-entry: steps since last visit + edge prompt |
+| \`ctx.outputFormatInstruction\` | Pre-built frontmatter format block (inject into system prompt) |
+
+Typical system prompt structure:
+\`\`\`
+[outputFormatInstruction]
+[rolePrompt from buildRolePrompt()]
+[workflow metadata]
+\`\`\`
+
+## Storing Session Detail
+
+Store your turn history as a CAS merkle DAG for debugging and replay:
+
+\`\`\`typescript
+// Store each turn as a CAS text node
+const turnHash = await store.put(textSchema, { content: turnData });
+
+// Build a detail node referencing all turns
+const detailHash = await store.put(detailSchema, { turns: turnHashes });
+\`\`\`
+
+The \`detailHash\` is preserved from the first \`run()\` call — retry \`continue()\` calls don't overwrite it.
+
+## Registration
+
+Register your adapter in \`~/.uncaged/workflow/config.yaml\`:
+
+\`\`\`yaml
+agents:
+  my-agent:
+    command: uwf-my-agent
+    args: []
+\`\`\`
+
+Use it:
+\`\`\`bash
+uwf thread exec <thread-id> --agent my-agent
+\`\`\`
+
+Or set as default:
+\`\`\`yaml
+defaultAgent: my-agent
+\`\`\`
+
+## Existing Adapters
+
+| Adapter | Package | Backend |
+|---------|---------|---------|
+| \`uwf-hermes\` | \`@uncaged/workflow-agent-hermes\` | Hermes ACP (chat sessions) |
+| \`uwf-builtin\` | \`@uncaged/workflow-agent-builtin\` | Direct OpenAI API (tools + loop) |
+| \`uwf-claude-code\` | \`@uncaged/workflow-agent-claude-code\` | Claude Code CLI |
+
+Study these for patterns on prompt building, session management, and detail storage.
+
+## Checklist
+
+1. Implement \`run(ctx)\` — build prompt, call LLM, return output + detailHash + sessionId
+2. Implement \`continue(sessionId, message, store)\` — resume session for frontmatter correction
+3. Store session detail as CAS nodes (for debugging)
+4. Ensure output starts with \`---\` frontmatter block
+5. Add a \`bin\` entry in \`package.json\` for the CLI command
+6. Register in config.yaml and test with \`uwf thread exec --agent <name>\`

+
+## Role Definition
+
+| Field | Purpose |
+|-------|---------|
+| \`description\` | Short description for humans and moderator context |
+| \`goal\` | Injected as the agent's system-level objective |
+| \`capabilities\` | Keyword tags — agent loads matching skills before starting |
+| \`procedure\` | Step-by-step instructions the agent follows |
+| \`output\` | Describes what to produce and which \`$status\` values to use |
+| \`frontmatter\` | JSON Schema defining the structured output fields |
+
+### Role Design Principles
+
+- **Single responsibility** — each role does one thing well
+- **Minimal context** — don't overload a role with too many steps; split if needed
+- **Clear status values** — each status should map to a distinct graph edge
+- **Explicit output** — tell the agent exactly what \`$status\` values are valid
+
+## Frontmatter Schema
+
+The \`frontmatter\` field is a standard JSON Schema. It defines the structured fields the agent must output in YAML frontmatter.
+
+### \`$status\` Field
+
+\`$status\` is the only standard field. Its value determines which graph edge the moderator follows. Use \`const\` to constrain each variant:
+
+\`\`\`yaml
+frontmatter:
+  oneOf:
+    - properties:
+        $status: { const: "done" }
+        result: { type: string }
+      required: [$status, result]
+    - properties:
+        $status: { const: "failed" }
+        error: { type: string }
+      required: [$status, error]
+\`\`\`
+
+### Custom Fields
+
+Add any fields you need for data passing between roles. These are available in edge prompts via Mustache templates.
+
+### Flat Schema (Single Status)
+
+When a role has only one outcome:
+
+\`\`\`yaml
+frontmatter:
+  properties:
+    $status: { const: "done" }
+    summary: { type: string }
+  required: [$status, summary]
+\`\`\`
+
+## Graph Routing
+
+The graph maps each role's \`$status\` values to the next role:
+
+\`\`\`
+graph[role][$status] → { role: nextRole, prompt: edgePrompt }
+\`\`\`
+
+### Special Nodes
+
+| Node | Purpose |
+|------|---------|
+| \`$START\` | Entry point — status key is always \`_\` (unconditional) |
+| \`$END\` | Terminal — thread completes and is archived |
+
+### Edge Prompts
+
+Use triple-brace Mustache (\`{{{field}}}\`) to pass data from the previous step's output:
+
+\`\`\`yaml
+graph:
+  planner:
+    ready: { role: developer, prompt: "Implement plan {{{plan}}} in {{{repoPath}}}." }
+\`\`\`
+
+The fields referenced must exist in the source role's frontmatter schema.
+
+### Loops and Branching
+
+Roles can route back to previous roles (loops) or to different roles based on status (branching):
+
+\`\`\`yaml
+graph:
+  reviewer:
+    approved: { role: tester, prompt: "Run tests." }
+    rejected: { role: developer, prompt: "Fix: {{{comments}}}" }  # loop back
+\`\`\`
+
+### Fail Routing
+
+Route failures to a cleanup role or \`$END\`:
+
+\`\`\`yaml
+graph:
+  developer:
+    done: { role: reviewer, prompt: "Review changes." }
+    failed: { role: cleanup, prompt: "Clean up: {{{error}}}" }
+\`\`\`
+
+## Self-Testing
+
+### Step-by-Step Verification
+
+\`\`\`bash
+# Start a thread directly from YAML file (no registration needed)
+uwf thread start my-workflow.yaml -p "Test prompt"
+
+# Or register first, then start by name
+uwf workflow add my-workflow.yaml
+uwf thread start my-workflow -p "Test prompt"
+
+# Execute one step at a time to verify routing
+uwf thread exec <thread-id>
+
+# Inspect step output
+uwf step list <thread-id>
+uwf step show <step-hash>
+
+# Check the CAS data
+uwf cas get <output-hash>
+\`\`\`
+
+### Validation Checklist
+
+1. Every \`$status\` value in a role's frontmatter has a matching edge in the graph
+2. Every field referenced in edge prompts (\`{{{field}}}\`) exists in the source role's schema
+3. Every role referenced in the graph exists in \`roles\`
+4. \`$START\` has exactly one edge with key \`_\`
+5. At least one path leads to \`$END\`
+6. No orphan roles (defined but never routed to)
+
+## Common Pitfalls
+
+- **Missing graph edge** — if a role can produce \`$status: failed\` but the graph has no \`failed\` edge, the moderator will error
+- **Mustache field mismatch** — referencing \`{{{branch}}}\` in an edge prompt but the source schema has \`branchName\` instead
+- **Overly complex roles** — a role with 20 steps should be split; each role should be completable in one agent turn
+- **No fail path** — always handle failure; route to cleanup or \`$END\`

+
+## Coding Conventions
+
+### Functional-first
+
+| Rule | Description |
+|------|-------------|
+| \`type\` over \`interface\` | All type definitions use \`type\` |
+| \`function\` over \`class\` | Pure functions + closures, no class |
+| No \`this\` | Functions must not depend on \`this\` context |
+| No inheritance | No \`extends\`, \`implements\`, \`abstract\` |
+| No optional properties | Use \`T \\| null\` instead of \`?:\` |
+| Immutability first | Use \`Readonly<T>\`, \`as const\`, avoid mutation |
+
+Classes allowed only when required by third-party libraries or for Error subclasses.
+
+### Error Handling
+
+- \`Result<T, E>\` type for expected failures (\`ok\`/\`err\` constructors from \`@uncaged/workflow-util\`)
+- \`throw\` only for unrecoverable bugs
+- No try-catch for flow control
+
+### Async
+
+Always \`async/await\`, never \`.then()\` chains.
+
+### Logging
+
+\`console.*\` is banned (Biome \`noConsole\` rule). Use the structured logger:
+
+\`\`\`typescript
+import { createLogger } from "@uncaged/workflow-util";
+const log = createLogger();
+log("4KNMR2PX", "Loading workflow...");  // 8-char Crockford Base32 tag
+\`\`\`
+
+Each call site gets a unique hand-written tag. \`grep "4KNMR2PX"\` in logs → instant code location.
+
+CLI package (\`@uncaged/cli-workflow\`) may use \`console.log\` for user-facing output with a biome-ignore comment.
+
+### No Dynamic Import
+
+No \`await import()\` in production code. Always static top-level \`import\`. Test files are exempt.
+
+### Naming
+
+- Workflow names: verb-first kebab-case (\`solve-issue\`, \`review-code\`)
+- IDs: Crockford Base32 — CAS hash (XXH64, 13-char), Thread ID (ULID, 26-char)
+
+## Development Workflow
+
+\`\`\`bash
+bun install                 # install all workspace deps
+bun run build               # tsc --build (all packages)
+bun run check               # tsc + biome check + lint-log-tags
+bun run format              # biome format --write
+bun test                    # run all tests
+\`\`\`
+
+Before committing: \`bun run check\` + \`bun test\` must both pass.
+
+### Testing
+
+- \`cli-workflow\`: vitest
+- Other packages: \`bun test\`
+- Test files live in \`__tests__/\` directories
+
+### Publishing
+
+Fixed-mode versioning — all \`@uncaged/*\` packages share the same version number.
+
+\`\`\`bash
+bun changeset               # describe the change
+bun version                 # bump versions + changelogs
+bun release                 # build + test + publish to npmjs
+\`\`\`
+
+## Key Modules
+
+### Moderator (\`cli-workflow/src/moderator/\`)
+
+Status-based graph evaluator. Reads \`graph[lastRole][output.$status]\` to determine the next role. Zero LLM cost.
+
+### Extract Pipeline (\`workflow-util-agent/src/\`)
+
+1. Agent produces frontmatter markdown
+2. \`parseFrontmatterMarkdown()\` extracts YAML frontmatter
+3. \`tryFrontmatterFastPath()\` validates against role's output schema
+4. If fast path fails, retries up to 2 times via agent continue
+5. Validated output stored as CAS node
+
+### createAgent Factory (\`workflow-util-agent/src/run.ts\`)
+
+Shared entry point for all agent CLIs. Handles:
+- Argument parsing (\`--thread\`, \`--role\`, \`--prompt\`)
+- Context building (thread history, workflow definition)
+- Output extraction and CAS persistence
+- Frontmatter retry loop
+
+### CAS Integration
+
+All data is CAS-addressed via \`@uncaged/json-cas\`:
+- \`store.put(schemaHash, data)\` → content hash
+- \`store.get(hash)\` → node
+- \`validate(store, node)\` → schema check
+- Schemas registered at workflow add time

+Guide for using the uwf CLI to manage workflows and threads.
+
+## Quick Start
+
+\`\`\`bash
+# 1. Configure provider and model
+uwf setup
+
+# 2. Register a workflow
+uwf workflow add my-workflow.yaml
+
+# 3. Start a thread (creates but does not execute)
+uwf thread start my-workflow -p "Build a login page"
+
+# 4. Execute the thread (runs moderator → agent → extract cycles)
+uwf thread exec <thread-id>          # one step
+uwf thread exec <thread-id> -c 10    # up to 10 steps
+uwf thread exec <thread-id> -c 10 --background  # run in background
+\`\`\`
+
+## Concepts
+
+- **Workflow** — YAML definition with roles and a routing graph; stored as a CAS node
+- **Thread** — A running instance of a workflow; a chain of step nodes in CAS
+- **Step** — One moderator → agent → extract cycle; contains the role's structured output
+- **CAS** — Content-addressable store; every artifact is hashed (XXH64, Crockford Base32)
+
+## Setup
+
+\`\`\`
+uwf setup                                          # interactive wizard
+uwf setup --provider <name> --base-url <url> \\

+           [--agent <name>]                         # optional default agent
+\`\`\`
+
+Config is stored at \`~/.uncaged/workflow/config.yaml\`. Override storage root with \`UNCAGED_WORKFLOW_STORAGE_ROOT\`.
+
+## Workflow Commands
+
+\`\`\`
+uwf workflow add <file>            # register from YAML file
+uwf workflow show <id>             # show by name or CAS hash
+uwf workflow list                  # list all registered workflows
+\`\`\`
+
+You can also pass a file path directly to \`uwf thread start\` without registering first.
+
+## Thread Lifecycle
+
+\`\`\`
+uwf thread start <workflow> -p <prompt>            # create thread
+uwf thread exec <thread-id>                        # execute one step

+               [--skip <n>]                        # skip first n results
+               [--take <n>]                        # limit results
+uwf thread read <thread-id>                        # render context as markdown
+               [--quota <chars>]                   # max output chars (default 4000)

+uwf thread cancel <thread-id>                      # cancel and archive thread
+\`\`\`
+
+### Typical Lifecycle
+
+\`\`\`
+start → exec (repeat) → thread reaches $END → auto-completed
+                       → or: cancel to abort
+\`\`\`
+
+## Step Commands
+
+\`\`\`
+uwf step list <thread-id>         # list all steps
+uwf step show <step-hash>         # show step details
+uwf step fork <step-hash>         # fork thread from a step (branch)
+\`\`\`
+
+Forking creates a new thread that shares history up to the fork point — useful for retrying from a known-good state.
+
+## CAS Commands
+
+\`\`\`
+uwf cas get <hash>                 # read a node (type + payload)
+            [--timestamp]          # include timestamp
+uwf cas put <type-hash> <data>     # store typed JSON, print hash
+uwf cas put-text <text>            # store plain text, print hash
+uwf cas has <hash>                 # check existence
+uwf cas refs <hash>                # list direct references
+uwf cas walk <hash>                # recursive traversal
+uwf cas reindex                    # rebuild type index
+uwf cas schema list                # list schemas
+uwf cas schema get <hash>          # show schema definition
+\`\`\`
+
+## Log Commands
+
+\`\`\`
