+# AI Agents — Deaf-First Platform
+
+This document describes the AI agents used in the Deaf-First Platform ecosystem, their capabilities, constraints, and integration points.
+
+## Overview
+
+The Deaf-First Platform uses AI agents to automate workflows, assist users with accessibility needs, and manage CI/CD processes.
+
+## Agents
+
+### Copilot Coding Agent
+
+- **Purpose**: Automates code changes, CI fixes, PR creation, and repository maintenance.
+- **Capabilities**: Code generation, file editing, branch management, PR creation.
+- **Constraints**: Cannot push directly; all changes go through GitHub pull requests. Follows repository coding guidelines.
+
+### AI Workspace (`/ai`)
+
+- **Purpose**: Provides AI-powered features for the Deaf-First SaaS platform including sign language recognition and accessibility workflows.
+- **Capabilities**: OpenAI API integration, custom model endpoints.
+- **Constraints**: API keys must be stored as environment secrets. No hardcoded credentials.
+
+### DeafAuth Service (`Services/deafauth`)
+
+- **Purpose**: Biometric and accessibility-first authentication for deaf and hard-of-hearing users.
+- **Capabilities**: Sign language recognition for authentication, accessible MFA.
+- **Constraints**: All biometric data must be processed locally; no PII sent to third parties.
+
+### PinkSync Service (`Services/pinksync`)
+
+- **Purpose**: Real-time sign language video synchronization and captioning.
+- **Capabilities**: Video stream processing, live caption generation.
+- **Constraints**: Video data is not stored beyond session scope.
+
+## Security
+
+- All agents run with the principle of least privilege.
+- No agent may commit secrets, credentials, or private keys.
+- Agent activity is audited via GitHub Actions logs.
