# AgentPing - Agent-Human Interaction Protocol

## Overview

AgentPing provides structured communication between AI agents and humans. Instead of unstructured text, agents create typed "pings" that render appropriately across surfaces (CLI, web UI, Slack, Telegram).

**Phase 2 Status (Production Ready):**
- ✅ 198 React components with Cyber-Premium dark theme
- ✅ 38 E2E tests passing across 5 browsers (Chromium, Firefox, WebKit, Mobile)
- ✅ Full ADA compliance with WCAG 2.1 AA standards
- ✅ Responsive design (mobile, tablet, desktop)
- ✅ Tailwind CSS v4 integration
- ✅ Storybook documentation for P0/P1 components

## Quick Decision Tree

```
Agent needs human input?
|
+-> Simple yes/no?
|   +-> Use `agentping approve "Deploy to production?"`
|
+-> Multiple options?
|   +-> Use `agentping select --options "A,B,C" "Choose approach"`
|
+-> Open-ended question?
|   +-> Use `agentping ask "What should I focus on?"`
|
+-> Multiple steps to approve?
|   +-> Use `agentping approve-steps --file steps.json`
|
+-> Just informing (no response)?
    +-> Use `agentping notify "Task completed"`
```

## Installation

```bash
# Via npm (global)
npm install -g @agentping/cli

# Via pnpm (monorepo)
pnpm add @agentping/cli

# Verify
agentping --version
```

## Core Commands

### 1. Approval (Yes/No)

Request approval for an action:

```bash
# Basic approval
agentping approve "Deploy to production?"

# With JSON output for agents
agentping approve "Run database migration?" --json

# With timeout
agentping approve "Execute build?" --timeout 60

# Exit codes: 0=approved, 1=denied, 2=timeout, 3=error
```

JSON Output:
```json
{
  "approved": true,
  "action": "approved",
  "enrichment": {
    "directives": [
      {"type": "constraint", "rule": "run during low-traffic hours"}
    ],
    "notes": "approved for staging first"
  }
}
```

### 2. Ask (Freeform Question)

Ask a question and wait for response:

```bash
# Open-ended question
agentping ask "What should I prioritize?"

# With suggested options
agentping ask "Which approach?" --options "A,B,C"

# JSON output for parsing
agentping ask "Database choice?" --options "postgres,mysql,sqlite" --json
```

JSON Output:
```json
{
  "action": "answered",
  "data": {
    "type": "answer",
    "value": "postgres"
  },
  "enrichment": {
    "notes": "we already use postgres in prod"
  }
}
```

### 3. Select (Multiple Choice)

Present options for selection:

```bash
# Single selection
agentping select --title "Choose framework" --options "React,Vue,Svelte"

# Multiple selection allowed
agentping select --title "Select features" --options "auth,api,ui" --multiple

# From JSON file
agentping select --file options.json --json
```

Options JSON format:
```json
{
  "title": "Choose deployment target",
  "options": [
    {"id": "prod", "label": "Production", "description": "Live environment"},
    {"id": "staging", "label": "Staging", "description": "Pre-production"}
  ],
  "allowMultiple": false
}
```

### 4. Step Approval (Multi-Step)

Request approval for multiple steps:

```bash
agentping approve-steps --file steps.json --json
```

Steps JSON format:
```json
{
  "title": "Database Migration Plan",
  "context": "Migrating to new schema version",
  "steps": [
    {"id": "backup", "description": "Create backup", "risk": "low", "reversible": true},
    {"id": "migrate", "description": "Run migration", "risk": "medium", "reversible": true},
    {"id": "verify", "description": "Verify integrity", "risk": "low", "reversible": true}
  ],
  "allowPartial": true
}
```

JSON Output:
```json
{
  "action": "selected",
  "data": {
    "type": "step_approval",
    "approvedSteps": ["backup", "verify"],
    "deniedSteps": ["migrate"]
  },
  "enrichment": {
    "directives": [
      {"type": "constraint", "rule": "wait for QA sign-off before migrate"}
    ]
  }
}
```

### 5. Notify (Fire-and-Forget)

Send notification without waiting for response:

```bash
# Info notification
agentping notify "Build completed successfully"

# Warning
agentping notify --level warning "Tests are slow (>5m)"

# Error
agentping notify --level error "Deployment failed"
```

### 6. Daemon Management

Control the AgentPing daemon:

```bash
# Start daemon
agentping daemon start

# Check status
agentping daemon status

# Stop daemon
agentping daemon stop

# Restart
agentping daemon restart
```

## Web UI Development

### Running the Development Server

```bash
# Start daemon (in background)
cd packages/adapters/daemon
pnpm dev &

# Start web UI (in foreground)
cd packages/adapters/web-ui
pnpm dev

# Open browser to http://localhost:7891
```

### Running Storybook

```bash
cd packages/adapters/web-ui
pnpm storybook

# Open browser to http://localhost:6006
```

**Available Stories:**
- P0 Components: Badge, Spinner, StatusIndicator, ProgressBar, ToggleSwitch, SearchInput, TextArea, Slider, DatePicker, MultiSelect
- P1 Components: PingCard, StepChecklist, SelectionList, EnrichmentPanel, QuickActions

See [Component Reference](./references/components.md) for full inventory.

### Running E2E Tests

```bash
# Install Playwright browsers
npx playwright install

# Build required packages
pnpm --filter @agentping/core build
pnpm --filter @agentping/storage-sqlite build
pnpm --filter @agentping/http-api build
pnpm --filter @agentping/daemon build

# Run E2E tests (38 tests × 5 browsers = 190 test runs)
cd packages/adapters/web-ui
pnpm test:e2e

# View HTML report
npx playwright show-report
```

**Test Coverage:**
- All 10 ping types (Notification, Approval, Question, Selection, StepApproval, Research, Review, TaskWorkflow, Secret, Custom)
- All P1 components (PingCard, StepChecklist, SelectionList, QuickActions, EnrichmentPanel)
- Responsive layouts (mobile, tablet, desktop)
- Keyboard navigation (j/k for navigation, 'a' for approve)
- Accessibility (ARIA roles, screen reader support)

## Agent-First JSON Interface

All commands support `--json` flag for structured output. Agents should:

1. Always use `--json` flag
2. Parse exit codes: 0=success, 1=denied, 2=timeout, 3=error
3. Handle enrichment directives in responses

### Input via stdin

```bash
# Pipe JSON input
echo '{"title":"Deploy?","action":"deploy to prod"}' | agentping approve --stdin --json

# From file
cat ping.json | agentping approve --stdin --json
```

### Environment Variables

```bash
AGENTPING_URL=http://localhost:7890  # API endpoint
AGENTPING_TIMEOUT=300                # Default timeout (seconds)
AGENTPING_AGENT_ID=my-agent          # Default agent ID
AGENTPING_SESSION_ID=session-123     # Default session ID
```

## Ping Types Reference

| Type | Use Case | Response |
|------|----------|----------|
| `notification` | FYI, no response | Auto-dismissed |
| `question` | Open-ended query | Text answer |
| `approval` | Yes/no decision | approved/denied |
| `step_approval` | Multi-step approval | Selected steps |
| `selection` | Pick from options | Selected IDs |
| `research_request` | Research direction | Direction IDs |
| `review_request` | Review content | Feedback |
| `secret` | Sensitive input | Masked value |
| `custom` | Extensible | Custom data |

## Directive Types

Humans can enrich responses with directives:

| Directive | Purpose | Example |
|-----------|---------|---------|
| `focus_on` | Direct attention | `{"type":"focus_on","target":"auth flow"}` |
| `skip` | Ignore something | `{"type":"skip","target":"unit tests"}` |
| `constraint` | Add rule | `{"type":"constraint","rule":"no breaking changes"}` |
| `prioritize` | Set priority | `{"type":"prioritize","items":["security","perf"]}` |
| `timeline` | Time constraint | `{"type":"timeline","deadline":"EOD","flexibility":"soft"}` |
| `reference` | Provide link | `{"type":"reference","url":"https://..."}` |
| `alternative` | Suggest option | `{"type":"alternative","suggestion":"use Redis"}` |

## Design System

AgentPing uses the **Cyber-Premium** dark theme with:

- **Background**: Deep black (#050505) with subtle elevation layers
- **Text**: High-contrast (#ededed primary, #a1a1aa secondary)
- **Accents**: Neon cyan (#00e5ff), green (#00ff9d), pink (#ff2a6d), amber (#ffb800)
- **Effects**: Glassmorphism, neon glows, smooth animations
- **Typography**: Inter (sans), JetBrains Mono (code)

See [Design Standards](./references/design-standards.md) for complete reference.

## Accessibility (ADA Compliance)

All components meet WCAG 2.1 AA standards:

- ✅ Contrast ratios: 4.5:1 (normal text), 3:1 (large text, interactive)
- ✅ Focus indicators: 2px cyan outline on keyboard navigation
- ✅ Touch targets: 44×44px minimum (mobile), 32px (desktop)
- ✅ Screen reader support: ARIA roles, labels, live regions
- ✅ Keyboard navigation: Tab, Enter/Space, Escape, Arrow keys
- ✅ Reduced motion: Respects `prefers-reduced-motion`

See [Design Standards](./references/design-standards.md) for component-specific ADA checklists.

## Adapter Development

Create custom adapters for new platforms:

```bash
# Generate adapter scaffold
agentping adapter create --name myplatform --template default
```

This creates:
```
adapters/myplatform/
+-- parser.ts      # Message -> PingSpec
+-- renderer.ts    # Response -> Native format
+-- config.yaml    # Platform settings
+-- index.ts       # Barrel export
```

### Parser Interface

```typescript
interface IInteractionParser {
  readonly name: string;
  readonly priority: number;  // Higher = tried first
  canParse(ping: Ping): boolean;
  parse(ping: Ping): ParsedInteraction;
}
```

### ParsedInteraction Output

```typescript
interface ParsedInteraction {
  interactionType: string;      // UI component hint
  quickActions: QuickAction[];  // 1-click responses
  uiHints: Record<string, unknown>;
  fallbackText: string;         // Text-only fallback
  fallbackOptions: string[];    // Simple options
}
```

## Error Handling

Exit codes:
- `0` - Success (approved/answered)
- `1` - Denied/rejected
- `2` - Timeout
- `3` - Error (network, validation, etc.)

Error JSON format:
```json
{
  "error": true,
  "code": "TIMEOUT",
  "message": "Response timeout after 300s",
  "pingId": "ping-abc123"
}
```

## Examples for AI Agents

### Claude Code Integration

```bash
# Before destructive operation
result=$(agentping approve "Delete 47 files from /src?" --json)
if [ $? -eq 0 ]; then
  rm -rf /src/old/*
fi

# Get user direction
direction=$(agentping ask "Which feature should I implement first?" \
  --options "auth,api,dashboard" --json | jq -r '.data.value')
```

### Programmatic (TypeScript)

```typescript
import { PingService } from '@agentping/core';

const service = new PingService(store, parsers);

const ping = await service.createPing({
  agentId: 'my-agent',
  agentName: 'My Agent',
  sessionId: 'session-123',
  payload: {
    type: 'approval',
    title: 'Deploy to production?',
    action: 'deploy',
    risk: 'high'
  }
});

const response = await service.waitForResponse(ping.id, 300000);
if (response?.action === 'approved') {
  // proceed
}
```

## Troubleshooting

**Daemon not running**
```bash
agentping daemon status
agentping daemon start
```

**Timeout issues**
```bash
# Increase timeout
agentping approve "Long decision?" --timeout 600
```

**Connection refused**
```bash
# Check API endpoint
curl http://localhost:7890/health
```

**E2E tests failing**
```bash
# Rebuild core packages
pnpm --filter @agentping/core build
pnpm --filter @agentping/storage-sqlite build
pnpm --filter @agentping/http-api build
pnpm --filter @agentping/daemon build

# Ensure servers are running
pnpm --filter @agentping/daemon dev &
pnpm --filter @agentping/web-ui dev &
```

## Technique Map

- **Identify scope** — Determine what the skill applies to before executing.
- **Follow workflow** — Use documented steps; avoid ad-hoc shortcuts.
- **Verify outputs** — Check results match expected contract.
- **Handle errors** — Graceful degradation when dependencies missing.
- **Reference docs** — Load references/ when detail needed.
- **Preserve state** — Don't overwrite user config or artifacts.

## Technique Notes

Skill-specific technique rationale. Apply patterns from the skill body. Progressive disclosure: metadata first, body on trigger, references on demand.

## Prompt Architect Overlay

**Role Definition:** Specialist for agentping domain. Executes workflows, produces artifacts, routes to related skills when needed.

**Input Contract:** Context, optional config, artifacts from prior steps. Depends on skill.

**Output Contract:** Artifacts, status, next-step recommendations. Format per skill.

**Edge Cases & Fallbacks:** Missing context—ask or infer from workspace. Dependency missing—degrade gracefully; note in output. Ambiguous request—clarify before proceeding.
