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

# 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:

# 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:

{
  "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:

# 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:

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

3. Select (Multiple Choice)

Present options for selection:

# 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:

{
  "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:

agentping approve-steps --file steps.json --json

Steps JSON format:

{
  "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",    
  
   

JSON Output:

{
  "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:

# 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:

# Start daemon
agentping daemon start

# Check status
agentping daemon status

# Stop daemon
agentping daemon stop

# Restart
agentping daemon restart

Web UI Development

Running E2E Tests

# 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

# 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

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

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 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 for component-specific ADA checklists.

Adapter Development

Create custom adapters for new platforms:

# 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

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

ParsedInteraction Output

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:

{
  "error": true,
  "code": "TIMEOUT",
  "message": "Response timeout after 300s",
  "pingId": "ping-abc123"
}

Examples for AI Agents

Claude Code Integration

# 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)

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

agentping daemon status
agentping daemon start

Timeout issues

# Increase timeout
agentping approve "Long decision?" --timeout 600

Connection refused

# Check API endpoint
curl http://localhost:7890/health

E2E tests failing

# 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.
