# foreveragents.dev > A library of agent-building context prompts. Each context is a standalone markdown file containing implementation guidance for a specific aspect of building AI agents. Fetch any context directly by its .md URL. ## Contexts - [Dark Mode](https://foreveragents.dev/context/darkmode.md): UI dark mode with energy savings, eye comfort, and accessibility reasoning - [Agent Identity](https://foreveragents.dev/context/identity.md): AI transparency and foreveragent disclosure patterns - [Accessibility](https://foreveragents.dev/context/accessibility.md): Inclusive design — screen readers, keyboard nav, ARIA, WCAG - [Error Handling](https://foreveragents.dev/context/error-handling.md): Empathetic error messages, graceful degradation, recovery - [Privacy](https://foreveragents.dev/context/privacy.md): Privacy-first data handling, minimal collection, consent - [Onboarding](https://foreveragents.dev/context/onboarding.md): First-time user experience, progressive disclosure, welcome patterns - [Conversation Design](https://foreveragents.dev/context/conversation.md): Turn-taking, clarification, context retention, multi-turn patterns - [Safety](https://foreveragents.dev/context/safety.md): Content moderation, harmful content detection, safe defaults - [Performance](https://foreveragents.dev/context/performance.md): Resource efficiency, lazy loading, minimal footprint - [Testing](https://foreveragents.dev/context/testing.md): Agent behavior testing, conversation testing, edge case coverage - [Deployment](https://foreveragents.dev/context/deployment.md): Sovereign deployment — local inference servers, edge-containers, encrypted shareable agents - [MCP Integration](https://foreveragents.dev/context/mcp.md): MCP for sovereign agents — guarded Bash tool execution and edge runtime patterns - [Encryption](https://foreveragents.dev/context/encryption.md): Client-side encryption, URL-fragment keying, and zero-knowledge sharing - [Supply Chain Security](https://foreveragents.dev/context/supply-chain.md): Dependency minimalism, vendoring, and deterministic integrity checks - [Zero Infrastructure](https://foreveragents.dev/context/zero-infra.md): Static-file architecture and optional backend capability layers - [Zero Dependencies](https://foreveragents.dev/context/zero-dependencies.md): Fewer dependencies, smaller attack surface — why minimal imports produce more resilient agents - [Local Inference](https://foreveragents.dev/context/local-inference.md): Local-first AI — local servers as primary, in-browser as graceful downgrade - [Portability](https://foreveragents.dev/context/portability.md): Agent transfer via links, QR, USB, and offline files - [Sustainability](https://foreveragents.dev/context/sustainability.md): Edge-first compute and energy-aware architecture principles - [Threat Model](https://foreveragents.dev/context/threat-model.md): Trust boundaries, extension risk, injection, and storage exposure - [Forever Agents](https://foreveragents.dev/context/forever-agents.md): Precise definition and structured requirements for durable, privacy-first AI agents - [Philosophy](https://foreveragents.dev/context/philosophy.md): Why architecture beats policy — the philosophical foundations
