v3.0.2

When using native tool calling, the assistant's tool_calls must be saved
in message history. Without this, the model doesn't know it already called
a tool and loops indefinitely calling the same tool.

This fix saves tool_calls in both startTaskWithNativeTools and
continueWithNativeTools methods.

Also updates @push.rocks/smartai to v0.13.3 for tool_calls forwarding support.

 # Changelog
 
+## 2026-03-06 - 3.0.2 - fix(agent)
+use output parameter when invoking onToolResult instead of toolCall.result
+
+- Replace (toolCall as any).result with the explicit output parameter when calling options.onToolResult.
+- Prevents undefined/misread results by aligning the callback with the tool runner's output signature.
+
+## 2026-03-06 - 3.0.1 - fix(readme)
+adjust ASCII art in README to fix box widths and spacing in agent diagram
+
+- Updated readme.md diagram: expanded 'Messages' box width and realigned 'streamText' and 'Tools' columns
+- Documentation-only change; no code or behavior affected
+
+## 2026-03-06 - 3.0.0 - BREAKING CHANGE(api)
+Migrate public API to ai-sdk v6 and refactor core agent architecture: replace class-based DualAgent/Driver/Guardian with a single runAgent function; introduce ts_tools factories for tools, a compactMessages compaction subpath, and truncateOutput utility; simplify ToolRegistry to return ToolSet and remove legacy BaseToolWrapper/tool classes; update package exports and dependencies and bump major version.
+
+- Major API break: DualAgent/Driver/Guardian classes and many legacy tool wrapper classes were removed and replaced by runAgent and functional tool factories.
+- Tooling refactor: new ts_tools (filesystem, shell, http, json) produce ToolSet-style tools; ToolRegistry now stores ToolSet and exposes getTools().
+- Context management: added compactMessages in ts_compaction for onContextOverflow handling and truncateOutput util to limit tool outputs.
+- Package changes: package.json bumped to 2.0.0, added exports map, updated devDependencies and dependencies (@push.rocks/smartai -> ^2.0.0, ai -> ^6.0.0, zod added).
+- Tests updated/added to reflect new API (unit tests and an end-to-end test added).
+- Consumers must update imports/usages (e.g. import runAgent, tool, z, stepCountIs and new subpath exports) — this is a breaking change. 
+
+## 2026-01-20 - 1.8.0 - feat(tools)
+add ToolRegistry, ToolSearchTool and ExpertTool to support on-demand tool visibility, discovery, activation, and expert/subagent tooling; extend DualAgentOrchestrator API and interfaces to manage tool lifecycle
+
+- Introduce ToolRegistry to manage tool registration, visibility (initial vs on-demand), activation, initialization, cleanup, and search
+- Add ToolSearchTool providing search/list/activate/details actions for discovering and enabling on-demand tools
+- Add ExpertTool to wrap a DualAgentOrchestrator as a sub-agent (expert) tool and the IExpertConfig interface
+- Extend DualAgentOrchestrator API: registerTool(tool, options?), registerExpert(config), enableToolSearch(), getRegistry(); registerStandardTools/start now initialize visible tools via registry
+- Add IToolRegistrationOptions and IToolMetadata/IExpertConfig types to smartagent.interfaces and export ToolRegistry/ToolSearchTool/ExpertTool in public entry points
+- Documentation updates (readme) describing tool visibility, tool search, and expert/subagent system
+
+## 2026-01-20 - 1.7.0 - feat(docs)
+document native tool calling support and update README to clarify standard and additional tools
+
+- Add 'Native Tool Calling' section documenting useNativeToolCalling option and behavior for providers (e.g., Ollama).
+- Explain tool name mapping when native tool calling is enabled (toolName_actionName) and streaming markers ([THINKING], [OUTPUT]).
+- Add example showing enabling useNativeToolCalling and note ollamaToken config option (Ollama endpoint).
+- Clarify that registerStandardTools() registers five tools (Filesystem, HTTP, Shell, Browser, Deno) and that JsonValidatorTool must be registered manually as an additional tool.
+- Documentation-only changes (README updates) — no code functionality changed in this diff.
+
+## 2026-01-20 - 1.6.2 - fix(release)
+bump version to 1.6.2
+
+- No source changes detected in the diff
+- Current package.json version is 1.6.1
+- Recommend a patch bump to 1.6.2 for a release
+
+## 2026-01-20 - 1.6.1 - fix(driveragent)
+include full message history for tool results and use a continuation prompt when invoking provider.collectStreamResponse
+
+- When toolName is provided, include the full messageHistory (do not slice off the last message) so tool result messages are preserved.
+- Set userMessage to a continuation prompt ('Continue with the task. The tool result has been provided above.') when handling tool results to avoid repeating the tool output.
+- Keeps existing maxHistoryMessages trimming and validates provider.collectStreamResponse is available before streaming.
+
+## 2026-01-20 - 1.6.0 - feat(smartagent)
+record native tool results in message history by adding optional toolName to continueWithNativeTools and passing tool identifier from DualAgent
+
+- continueWithNativeTools(message, toolName?) now accepts an optional toolName; when provided the message is stored with role 'tool' and includes a toolName property (cast to ChatMessage)
+- DualAgent constructs a toolNameForHistory as `${proposal.toolName}_${proposal.action}` and forwards it to continueWithNativeTools in both normal and error flows
+- Preserves tool-origin information in the conversation history to support native tool calling and tracking
+
+## 2026-01-20 - 1.5.4 - fix(driveragent)
+prevent duplicate thinking/output markers during token streaming and mark transitions
+
+- Add isInThinkingMode flag to track thinking vs output state
+- Emit "\n[THINKING] " only when transitioning into thinking mode (avoids repeated thinking markers)
+- Emit "\n[OUTPUT] " when transitioning out of thinking mode to mark content output
+- Reset thinking state after response completes to ensure correct markers for subsequent responses
+- Applied the same streaming marker logic to both response handling paths
+
+## 2026-01-20 - 1.5.3 - fix(driveragent)
+prefix thinking tokens with [THINKING] when forwarding streaming chunks to onToken
+
+- Wraps chunk.thinking with '[THINKING] ' before calling onToken to mark thinking tokens
+- Forwards chunk.content unchanged
+- Change applied in ts/smartagent.classes.driveragent.ts for both initial and subsequent assistant streaming responses
+- No API signature changes; only the token payloads sent to onToken are altered
+
+## 2026-01-20 - 1.5.2 - fix()
+no changes in this diff; nothing to release
+
+- No files changed; no release required
+- No code or dependency changes detected
+
+## 2026-01-20 - 1.5.1 - fix(smartagent)
+bump patch version to 1.5.1 (no changes in diff)
+
+- No code changes detected in the provided diff
+- Current package.json version is 1.5.0
+- Recommended semantic version bump: patch -> 1.5.1
+
+## 2026-01-20 - 1.5.0 - feat(driveragent)

+
+## 2026-01-20 - 1.4.0 - feat(docs)
+document Dual-Agent Driver/Guardian architecture, new standard tools, streaming/vision support, progress events, and updated API/export docs
+
+- Add DualAgentOrchestrator concept and describe Driver/Guardian agents and BaseToolWrapper
+- Document six standard tools including new JsonValidatorTool and expanded descriptions for Filesystem, Http, Shell, Browser, Deno
+- Add examples for scoped filesystem with exclusion patterns and line-range reads
+- Add token streaming (onToken) and progress events (onProgress) examples and event types
+- Document vision support for passing images as base64 and example usage
+- Expose additional config options in docs: name, verbose, maxResultChars, maxHistoryMessages, onProgress, onToken, logPrefix
+- Document additional result fields: toolCallCount, rejectionCount, toolLog, and error
+- Update API signatures in docs: run(task, options?) and registerScopedFilesystemTool(basePath, excludePatterns?)
+- Update re-exports to include IFilesystemToolOptions, TDenoPermission, JsonValidatorTool and re-export several smartai types
+
+## 2026-01-20 - 1.3.0 - feat(smartagent)
+add JsonValidatorTool and support passing base64-encoded images with task runs (vision-capable models); bump @push.rocks/smartai to ^0.12.0
+
+- Add JsonValidatorTool (validate/format actions) implemented in ts/smartagent.tools.json.ts
+- Export JsonValidatorTool from ts/index.ts
+- Add ITaskRunOptions interface (images?: string[]) in smartagent.interfaces.ts
+- DualAgent.run and Driver.startTask accept optional images and pass them to provider.chat/provider.chatStreaming; assistant responses added to message history
+- Bump dependency @push.rocks/smartai from ^0.11.1 to ^0.12.0 in package.json
+
+## 2026-01-20 - 1.2.7 - fix(deps(smartai))
+bump @push.rocks/smartai to ^0.11.0
+
+- package.json: @push.rocks/smartai updated from ^0.10.1 to ^0.11.0
+- Recommend a patch release since this is a dependency update with no breaking API changes: 1.2.7
+
+## 2026-01-20 - 1.2.6 - fix(deps)
+bump @push.rocks/smartai to ^0.10.1
+
+- Updated dependency @push.rocks/smartai from ^0.8.0 to ^0.10.1 in package.json

 # Project Readme Hints
 
 ## Overview
-`@push.rocks/smartagent` is an agentic framework built on top of `@push.rocks/smartai`. It provides autonomous AI agent capabilities including tool use, multi-step reasoning, and conversation memory.
+`@push.rocks/smartagent` v2.0.0 is an agentic loop built on Vercel AI SDK v6 via `@push.rocks/smartai`. It wraps `streamText` with `stopWhen: stepCountIs(n)` for parallel multi-step tool execution.
 
-## Architecture
-- **SmartAgent**: Main class that wraps SmartAi and adds agentic behaviors
-- **plugins.ts**: Imports and re-exports smartai
-- **index.ts**: Main entry point, exports SmartAgent class and relevant types
+## Architecture (v2)
+- **`runAgent()`**: Pure async function — the core agentic loop. No class state.
+- **`ToolRegistry`**: Lightweight helper for collecting tools into a `ToolSet`.
+- **`truncateOutput()`**: Utility to prevent tool output from bloating context.
+- **`compactMessages()`**: Context overflow handler (separate subpath export).
+
+## Source Layout
+```
+ts/              → core: runAgent, ToolRegistry, truncateOutput, interfaces
+ts_tools/        → built-in tool factories (filesystem, shell, http, json)
+ts_compaction/   → compactMessages helper for onContextOverflow
+```
+
+## Built-in Tools (ts_tools/)
+Each exports a factory returning a flat `ToolSet` (Record<string, Tool>):
+1. **filesystemTool()** → `read_file`, `write_file`, `list_directory`, `delete_file`
+2. **shellTool()** → `run_command`
+3. **httpTool()** → `http_get`, `http_post`
+4. **jsonTool()** → `json_validate`, `json_transform`
 
 ## Key Dependencies
-- `@push.rocks/smartai`: Provides the underlying multi-modal AI provider interface
+- `@push.rocks/smartai` ^2.0.0 — provider registry, `getModel()`, re-exports `tool`, `jsonSchema`
+- `ai` ^6.0.0 — Vercel AI SDK v6 (`streamText`, `stepCountIs`, `ModelMessage`, `ToolSet`)
+- `zod` ^3.25.0 — tool input schema definitions
+- `@push.rocks/smartfs`, `smartshell`, `smartrequest` — tool implementations
+
+## AI SDK v6 Key APIs
+- `streamText({ model, messages, tools, stopWhen: stepCountIs(20) })` — agentic loop
+- `tool({ description, inputSchema: z.object({...}), execute })` — define tools
+- `ModelMessage` — message type (replaces v4's `CoreMessage`)
+- `LanguageModelV3` — model type from `@ai-sdk/provider`
+- Result is `StreamTextResult` with PromiseLike properties (`await result.text`, etc.)
+
+## Package Exports
+- `.` → core (runAgent, ToolRegistry, truncateOutput, re-exports)
+- `./tools` → built-in tool factories
+- `./compaction` → compactMessages
+
+## Build
+- `pnpm build` → `tsbuild tsfolders --allowimplicitany`
+- Cross-folder imports via each folder's `plugins.ts` (tsbuild unpack resolves them)
 
 ## Test Structure
 - Tests use `@git.zone/tstest/tapbundle`
-- Tests must end with `export default tap.start();`
+- Tests must end with `export default tap.start()`
+- `pnpm test` → `tstest test/ --verbose`

 ## Overview
 
-SmartAgent implements a **dual-agent architecture** where AI safety isn't just an afterthought—it's baked into the core design:
+`@push.rocks/smartagent` wraps the AI SDK's `streamText` with `stopWhen: stepCountIs(n)` for **parallel multi-step tool execution**. No classes to instantiate, no lifecycle to manage — just one async function:
 
-- **🎯 Driver Agent**: The executor. Reasons about goals, plans steps, and proposes tool calls
-- **🛡️ Guardian Agent**: The gatekeeper. Evaluates every tool call against your policy, approving or rejecting with feedback
+```typescript
+import { runAgent, tool, z } from '@push.rocks/smartagent';
+import { getModel } from '@push.rocks/smartai';
 
-This design ensures safe tool use through **AI-based policy evaluation** rather than rigid programmatic rules. The Guardian can understand context, nuance, and intent—catching dangerous operations that simple regex or allowlists would miss.
+const model = getModel({
+  provider: 'anthropic',
+  model: 'claude-sonnet-4-5-20250929',
+  apiKey: process.env.ANTHROPIC_TOKEN,
+});
 
-### Why Dual-Agent?
+const result = await runAgent({
+  model,
+  prompt: 'What is 7 + 35?',
+  system: 'You are a helpful assistant. Use tools when asked.',
+  tools: {
+    calculator: tool({
+      description: 'Perform arithmetic',
+      inputSchema: z.object({
+        operation: z.enum(['add', 'subtract', 'multiply', 'divide']),
+        a: z.number(),
+        b: z.number(),
+      }),
+      execute: async ({ operation, a, b }) => {
+        const ops = { add: a + b, subtract: a - b, multiply: a * b, divide: a / b };
+        return String(ops[operation]);
+      },
+    }),
+  },
+  maxSteps: 10,
+});
 
-Traditional AI agents have a fundamental problem: they're given tools and expected to use them responsibly. SmartAgent adds a second AI specifically trained to evaluate whether each action is safe and appropriate. Think of it as separation of concerns, but for AI safety.
+console.log(result.text);    // "7 + 35 = 42"
+console.log(result.steps);   // number of agentic steps taken
+console.log(result.usage);   // { promptTokens, completionTokens, totalTokens }
+```

-## Quick Start
+**Key features:**
+
+- 🔄 **Multi-step agentic loop** — the model calls tools, sees results, and continues reasoning until done
+- ⚡ **Parallel tool execution** — multiple tool calls in a single step are executed concurrently
+- 🔧 **Auto-retry with backoff** — handles 429/529/503 errors with header-aware retry delays
+- 🩹 **Tool call repair** — case-insensitive name matching + invalid tool sink prevents crashes
+- 📊 **Token streaming** — `onToken` and `onToolCall` callbacks for real-time progress
+- 💥 **Context overflow handling** — detects overflow and invokes your `onContextOverflow` callback
+
+## Core API

-console.log('Result:', result.result);
-console.log('Iterations:', result.iterations);
-
-// Cleanup
-await orchestrator.stop();
-```
-
-## Standard Tools
-
-SmartAgent comes with five battle-tested tools out of the box:
-
-### 🗂️ FilesystemTool
-
-File and directory operations powered by `@push.rocks/smartfs`.
-
-**Actions**: `read`, `write`, `append`, `list`, `delete`, `exists`, `stat`, `copy`, `move`, `mkdir`
-
-```typescript
-// Example tool call by Driver
-<tool_call>
-  <tool>filesystem</tool>
-  <action>read</action>
-  <params>{"path": "/tmp/config.json"}</params>
-  <reasoning>Need to read the configuration file to understand the settings</reasoning>
-</tool_call>
-```
-
-**Scoped Filesystem**: Lock file operations to a specific directory:
-
-```typescript
-// Only allow access within a specific directory
-orchestrator.registerScopedFilesystemTool('/home/user/workspace');
-```
-
-### 🌐 HttpTool
-
-HTTP requests using `@push.rocks/smartrequest`.
-
-**Actions**: `get`, `post`, `put`, `patch`, `delete`
-
-```typescript
-<tool_call>

-  <action>get</action>
-  <params>{"url": "https://api.example.com/data", "headers": {"Authorization": "Bearer token"}}</params>
-  <reasoning>Fetching data from the API endpoint</reasoning>
-</tool_call>
-```
-
-### 💻 ShellTool
-
-Secure shell command execution using `@push.rocks/smartshell` with `execSpawn` (no shell injection possible).
-
-**Actions**: `execute`, `which`
-
-```typescript
-<tool_call>
-  <tool>shell</tool>
-  <action>execute</action>
-  <params>{"command": "ls", "args": ["-la", "/tmp"]}</params>
-  <reasoning>Listing directory contents to find relevant files</reasoning>
-</tool_call>
-```
-
-> 🔒 **Security Note**: The shell tool uses `execSpawn` with `shell: false`, meaning command and arguments are passed separately. This makes shell injection attacks impossible.
-
-### 🌍 BrowserTool
-
-Web page interaction using `@push.rocks/smartbrowser` (Puppeteer-based).
-
-**Actions**: `screenshot`, `pdf`, `evaluate`, `getPageContent`
-
-```typescript
-<tool_call>
-  <tool>browser</tool>
-  <action>getPageContent</action>
-  <params>{"url": "https://example.com"}</params>
-  <reasoning>Extracting text content from the webpage</reasoning>
-</tool_call>
-```
-
-### 🦕 DenoTool
-
-Execute TypeScript/JavaScript code in a **sandboxed Deno environment** with fine-grained permission control.
-
-**Actions**: `execute`, `executeWithResult`
-
-**Permissions**: `all`, `env`, `ffi`, `hrtime`, `net`, `read`, `run`, `sys`, `write`
-
-By default, code runs **fully sandboxed with no permissions**. Permissions must be explicitly requested and are subject to Guardian approval.
-
-```typescript
-// Simple code execution (sandboxed, no permissions)
-<tool_call>
-  <tool>deno</tool>
-  <action>execute</action>
-  <params>{"code": "console.log('Hello from Deno!')"}</params>
-  <reasoning>Running a simple script to verify the environment</reasoning>
-</tool_call>
-
-// Code with network permission
-<tool_call>
-  <tool>deno</tool>
-  <action>execute</action>
-  <params>{
-    "code": "const resp = await fetch('https://api.example.com/data'); console.log(await resp.json());",
-    "permissions": ["net"]
-  }</params>
-  <reasoning>Fetching data from API using Deno's fetch</reasoning>
-</tool_call>
-
-// Execute and parse JSON result
-<tool_call>
-  <tool>deno</tool>
-  <action>executeWithResult</action>
-  <params>{
-    "code": "const result = { sum: 2 + 2, date: new Date().toISOString() }; console.log(JSON.stringify(result));"
-  }</params>
-  <reasoning>Computing values and returning structured data</reasoning>
-</tool_call>
-```
-
-## Guardian Policy Examples
-
-The Guardian's power comes from your policy. Here are battle-tested examples:
-
-### 🔐 Strict Security Policy
-
-```typescript
-const securityPolicy = `
-SECURITY POLICY:
-1. REJECT any file operations outside /home/user/workspace
-2. REJECT any shell commands that could modify system state
-3. REJECT any HTTP requests to internal/private IP ranges
-4. REJECT any attempts to read environment variables or credentials
-5. FLAG and REJECT obfuscated code execution
-
-When rejecting, always explain:
-- What policy was violated
-- What would be a safer alternative
-`;
-```
-
-### 🛠️ Development Environment Policy
-
-```typescript
-const devPolicy = `
-DEVELOPMENT POLICY:
-- Allow file operations only within the project directory
-- Allow npm/pnpm commands for package management
-- Allow git commands for version control
-- Allow HTTP requests to public APIs only
-- REJECT direct database modifications
-- REJECT commands that could affect other users
-
-Always verify:
-- File paths are relative or within project bounds
-- Commands don't have dangerous flags (--force, -rf)
-`;
-```
-
-### 🦕 Deno Code Execution Policy
-
-```typescript
-const denoPolicy = `
-DENO CODE EXECUTION POLICY:
-- ONLY allow 'read' permission for files within the workspace
-- REJECT 'all' permission unless explicitly justified for the task
-- REJECT 'run' permission (subprocess execution) without specific justification
-- REJECT code that attempts to:
-  - Access credentials or environment secrets (even with 'env' permission)
-  - Make network requests to internal/private IP ranges
-  - Write to system directories
-- FLAG obfuscated or encoded code (base64, eval with dynamic strings)
-- Prefer sandboxed execution (no permissions) when possible
-
-When evaluating code:
-- Review the actual code content, not just permissions
-- Consider what data the code could exfiltrate
-- Verify network endpoints are legitimate public APIs
-`;
-```
-
-## Configuration Options
-
-```typescript
-interface IDualAgentOptions {
-  // Provider tokens (from @push.rocks/smartai)
-  openaiToken?: string;
-  anthropicToken?: string;
-  perplexityToken?: string;
-  groqToken?: string;
-  xaiToken?: string;
-
-  // Use existing SmartAi instance (optional - avoids duplicate providers)
-  smartAiInstance?: SmartAi;
-
-  // Provider selection
-  defaultProvider?: TProvider;      // For both Driver and Guardian
-  guardianProvider?: TProvider;     // Optional: separate provider for Guardian
-

+interface IAgentRunResult {
+  text: string;              // Final response text
+  finishReason: string;      // 'stop', 'tool-calls', 'length', etc.
+  steps: number;             // Number of agentic steps taken
+  messages: ModelMessage[];  // Full conversation for multi-turn
+  usage: {
+    promptTokens: number;
+    completionTokens: number;
+    totalTokens: number;
+  };
 }
 ```
 
-## Result Interface
+## Defining Tools 🛠️
+
+Tools use Vercel AI SDK's `tool()` helper with Zod schemas:
 
 ```typescript
-interface IDualAgentRunResult {
-  success: boolean;           // Whether task completed successfully
-  completed: boolean;         // Task completion status
-  result: string;             // Final result or response
-  iterations: number;         // Number of iterations taken
-  history: IAgentMessage[];   // Full conversation history
-  status: TDualAgentRunStatus; // 'completed' | 'max_iterations_reached' | etc.
-}
+import { tool, z } from '@push.rocks/smartagent';
 
-type TDualAgentRunStatus =
-  | 'completed'
-  | 'in_progress'
-  | 'max_iterations_reached'
-  | 'max_rejections_reached'
-  | 'clarification_needed'
-  | 'error';
-```
-
-## Custom Tools
-
-Create custom tools by extending `BaseToolWrapper`:
-
-```typescript
-import { BaseToolWrapper, IToolAction, IToolExecutionResult } from '@push.rocks/smartagent';
-
-class MyCustomTool extends BaseToolWrapper {
-  public name = 'custom';
-  public description = 'My custom tool for specific operations';
-
-  public actions: IToolAction[] = [
-    {
-      name: 'myAction',
-      description: 'Performs a custom action',
-      parameters: {
-        type: 'object',
-        properties: {
-          input: { type: 'string', description: 'Input for the action' },
-        },
-        required: ['input'],
-      },
-    },
-  ];
-
-  public async initialize(): Promise<void> {
-    // Setup your tool (called when orchestrator.start() runs)
-    this.isInitialized = true;
-  }
-
-  public async cleanup(): Promise<void> {
-    // Cleanup resources (called when orchestrator.stop() runs)
-    this.isInitialized = false;
-  }
-
-  public async execute(action: string, params: Record<string, unknown>): Promise<IToolExecutionResult> {
-    this.validateAction(action);
-    this.ensureInitialized();
-
-    if (action === 'myAction') {
-      return {
-        success: true,
-        result: { processed: params.input },
-      };
-    }
-
-    return { success: false, error: 'Unknown action' };
-  }
-
-  // Human-readable summary for Guardian evaluation
-  public getCallSummary(action: string, params: Record<string, unknown>): string {
-    return `Custom action "${action}" with input "${params.input}"`;
-  }
-}
-
-// Register custom tool
-orchestrator.registerTool(new MyCustomTool());
-```
-
-## Reusing SmartAi Instances
-
-If you already have a `@push.rocks/smartai` instance, you can share it:
-
-```typescript
-import { SmartAi } from '@push.rocks/smartai';
-import { DualAgentOrchestrator } from '@push.rocks/smartagent';
-
-const smartai = new SmartAi({ openaiToken: 'sk-...' });
-await smartai.start();
-
-const orchestrator = new DualAgentOrchestrator({
-  smartAiInstance: smartai,  // Reuse existing instance
-  guardianPolicyPrompt: '...',
-});
-
-await orchestrator.start();
-// ... use orchestrator ...
-await orchestrator.stop();
-
-// SmartAi instance lifecycle is managed separately
-await smartai.stop();
-```
-
-## Supported Providers
-
-SmartAgent supports all providers from `@push.rocks/smartai`:
-
-| Provider | Driver | Guardian |
-|----------|:------:|:--------:|
-| OpenAI | ✅ | ✅ |
-| Anthropic | ✅ | ✅ |
-| Perplexity | ✅ | ✅ |
-| Groq | ✅ | ✅ |
-| Ollama | ✅ | ✅ |
-| XAI | ✅ | ✅ |
-| Exo | ✅ | ✅ |
-
-**💡 Pro tip**: Use a faster/cheaper model for Guardian (like Groq) and a more capable model for Driver:
-
-```typescript
-const orchestrator = new DualAgentOrchestrator({
-  openaiToken: 'sk-...',
-  groqToken: 'gsk-...',
-  defaultProvider: 'openai',    // Driver uses OpenAI
-  guardianProvider: 'groq',     // Guardian uses Groq (faster, cheaper)
-  guardianPolicyPrompt: '...',
+const myTool = tool({
+  description: 'Describe what this tool does',
+  inputSchema: z.object({
+    param1: z.string().describe('What this parameter is for'),
+    param2: z.number().optional(),
+  }),
+  execute: async ({ param1, param2 }) => {
+    // Do work, return a string
+    return `Result: ${param1}`;
+  },
 });
 ```

+await runAgent({
+  model,
+  prompt: 'Do the thing',
+  tools: { myTool, anotherTool },
+  maxSteps: 10,
+});
 ```
 
+## ToolRegistry
+
+A lightweight helper for collecting tools:
+
+```typescript
+import { ToolRegistry, tool, z } from '@push.rocks/smartagent';
+
+const registry = new ToolRegistry();
+
+registry.register('random_number', tool({
+  description: 'Generate a random integer between min and max',
+  inputSchema: z.object({
+    min: z.number(),
+    max: z.number(),
+  }),
+  execute: async ({ min, max }) => {
+    return String(Math.floor(Math.random() * (max - min + 1)) + min);
+  },
+}));
+
+registry.register('is_even', tool({
+  description: 'Check if a number is even',
+  inputSchema: z.object({ number: z.number() }),
+  execute: async ({ number: n }) => n % 2 === 0 ? 'Yes' : 'No',
+}));
+
+const result = await runAgent({
+  model,
+  prompt: 'Generate a random number and tell me if it is even',
+  tools: registry.getTools(),
+  maxSteps: 10,
+});
+```
+
+## Built-in Tool Factories 🧰
+
+Import from the `@push.rocks/smartagent/tools` subpath:
+
+```typescript
+import { filesystemTool, shellTool, httpTool, jsonTool } from '@push.rocks/smartagent/tools';
+```
+
+### `filesystemTool(options?)`
+
+Returns: `read_file`, `write_file`, `list_directory`, `delete_file`
+
+```typescript
+const tools = filesystemTool({ rootDir: '/home/user/workspace' });
+
+await runAgent({
+  model,
+  prompt: 'Create a file called hello.txt with "Hello World"',
+  tools,
+  maxSteps: 5,
+});
+```
+
+Options:
+- `rootDir` — restrict all file operations to this directory. Paths outside it throw `Access denied`.
+
+### `shellTool(options?)`
+
+Returns: `run_command`
+
+```typescript
+const tools = shellTool({ cwd: '/tmp', allowedCommands: ['ls', 'echo', 'cat'] });
+
+await runAgent({
+  model,
+  prompt: 'List all files in /tmp',
+  tools,
+  maxSteps: 5,
+});
+```
+
+Options:
+- `cwd` — working directory for commands
+- `allowedCommands` — whitelist of allowed commands (if set, others are rejected)
+
+### `httpTool()`
+
+Returns: `http_get`, `http_post`
+
+```typescript
+const tools = httpTool();
+
+await runAgent({
+  model,
+  prompt: 'Fetch the data from https://api.example.com/status',
+  tools,
+  maxSteps: 5,
+});
+```
+
+### `jsonTool()`
+
+Returns: `json_validate`, `json_transform`
+
+```typescript
+const tools = jsonTool();
+
+// Direct usage:
+const result = await tools.json_validate.execute({
+  jsonString: '{"name":"test","value":42}',
+  requiredFields: ['name', 'value'],
+});
+// → "Valid JSON: object with 2 keys"
+```
+
+## Streaming & Callbacks 🎥
+
+Monitor the agent in real-time:
+
+```typescript
+const result = await runAgent({
+  model,
+  prompt: 'Analyze this data...',
+  tools,
+  maxSteps: 10,
+
+  // Token-by-token streaming
+  onToken: (delta) => process.stdout.write(delta),
+
+  // Tool call notifications
+  onToolCall: (toolName) => console.log(`\n🔧 Calling: ${toolName}`),
+});
+```
+
+## Context Overflow Handling 💥
+
+For long-running agents that might exceed the model's context window, use the compaction subpath:
+
+```typescript
+import { runAgent } from '@push.rocks/smartagent';
+import { compactMessages } from '@push.rocks/smartagent/compaction';
+
+const result = await runAgent({
+  model,
+  prompt: 'Process all 500 files...',
+  tools,
+  maxSteps: 100,
+
+  onContextOverflow: async (messages) => {
+    // Summarize the conversation to free up context space
+    return await compactMessages(model, messages);
+  },
+});
+```
+
+## Output Truncation ✂️
+
+Prevent large tool outputs from consuming too much context:
+
+```typescript
+import { truncateOutput } from '@push.rocks/smartagent';
+
+const { content, truncated, notice } = truncateOutput(hugeOutput, {
+  maxLines: 2000,   // default
+  maxBytes: 50_000, // default
+});
+```
+
+The built-in tool factories use `truncateOutput` internally.
+
+## Multi-Turn Conversations 💬
+
+Pass the returned `messages` back for multi-turn interactions:
+
+```typescript
+// First turn
+const turn1 = await runAgent({
+  model,
+  prompt: 'Create a project structure',
+  tools,
+  maxSteps: 10,
+});
+
+// Second turn — continues the conversation
+const turn2 = await runAgent({
+  model,
+  prompt: 'Now add a README to the project',
+  tools,
+  maxSteps: 10,
+  messages: turn1.messages, // pass history
+});
+```

-You analyze tasks, break them down into steps, and use tools to accomplish goals.

-## Tool Usage Format
-When you need to use a tool, output a tool call proposal in this format:

-  <tool>tool_name</tool>

-  <params>
-    {"param1": "value1", "param2": "value2"}

-</tool_call>

-1. Think step by step about what needs to be done
-2. Use only the tools that are available to you
-3. Provide clear reasoning for each tool call
-4. If a tool call is rejected, adapt your approach based on the feedback
-5. When the task is complete, indicate this clearly:

-<task_complete>
-  Brief summary of what was accomplished
-</task_complete>

-- Only propose ONE tool call at a time
