Promptise Foundry is an open-source framework designed for building, deploying, and managing production-ready autonomous AI agents. It addresses common challenges in agent development, such as limited reasoning capabilities, lack of robust state management, insufficient observability, and the need for secure, scalable agent deployment. The framework is positioned as a foundation layer for agentic intelligence, enabling teams to move from prototype to production with a unified system rather than assembling multiple disjointed libraries. The platform is built around five integrated subsystems, each designed to interoperate seamlessly. The Promptise Agent subsystem allows developers to turn any large language model into a production-ready agent with a single function call. Agents can automatically discover tools by pointing at MCP servers, search and inject relevant memory before each turn, and employ real-time security guardrails to block injection attacks. The Reasoning Engine subsystem offers composable reasoning patterns, enabling agents to build their own execution paths at runtime using up to 20 reasoning nodes such as Plan, Think, Act, Reflect, Critique, and Synthesize. Developers can use seven prebuilt reasoning patterns or create custom ones, with fine-grained control over each node's instructions, tools, models, and data flow. Promptise Foundry also provides an MCP Server & Client subsystem for building APIs that are accessible to AI agents. This includes features like JWT authentication, role-based access, rate limiting, circuit breakers, and HMAC audit logs, all with minimal code. The Agent Runtime subsystem manages lifecycle tasks such as cron scheduling, webhook triggers, crash recovery, cost budgeting, behavioral health monitoring, and mission-oriented execution, with deployment via YAML. The Prompt & Context subsystem structures prompts as typed blocks with priority-based token budgeting, supports context evolution, output validation with auto-retry, and thorough observability through an inspector and version registry. Additional features include vector memory with support for ChromaDB, Mem0, and in-memory options, semantic caching with per-user isolation and AES-256 encryption, GDPR-compliant data purging, human approval workflows, model fallback mechanisms, real-time streaming of tool and token events, and observability integrations with destinations such as Prometheus, OTel, and webhooks. Promptise Foundry is delivered as a Python package and is open source, emphasizing type safety and production readiness for teams building autonomous agents.
dot-prompt provides a structured approach to composing, reviewing, and managing prompts for AI applications. It addresses the challenge of prompt invisibility—where developers and teams lose track of the exact instructions sent to large language models—by turning prompts into inspectable, reusable components. prompt files, which can include branching logic, variables, and reusable fragments. This structure allows prompts to be separated from application code, making them readable and accessible to developers, product managers, designers, and domain experts alike. dot-prompt enables real-time preview of compiled prompts: users can select variables, see the exact output that will be sent to the AI, and instantly observe changes as variables are updated. Branching logic is resolved before submission, ensuring the AI receives a single, clear instruction rather than embedded conditionals. The tool supports fragment composition, allowing prompt authors to build prompts from reusable pieces such as skill definitions, context blocks, and examples, with static fragments cached and dynamic fragments fetched afresh each time. Input and output contracts can be declared, and dot-prompt validates both sides to detect breaking changes automatically. Version control is built in, recognizing the difference between breaking and non-breaking changes and prompting for versioning when necessary, so older versions remain available for callers who have not upgraded. dot-prompt is delivered as a language and viewer for writing and inspecting prompts, with files managed separately from codebases. It is intended for developers, product teams, domain experts, and founders who need visibility and control over AI prompt workflows.
