An AI-native product building platform that orchestrates AI coding agents through visual user story mapping and layered context engineering across planning, context injection, and build delivery.
Dossier is an orchestration platform for medium-to-large AI-assisted development projects, addressing the scaling challenges that arise when AI coding expands from prototypes to production products. It unifies product planning, context management, and build execution into a single visual interface.
Product Map & Planning Presents user story maps in a three-level hierarchy: Product → Workflow → Feature Card. A built-in Planning Agent automatically infers workflows from connected repositories and READMEs to populate the map.
Layered Context Engineering Each feature card links to a context card containing facts, assumptions, open questions, context documents, and generated prompts — ensuring agents receive human-validated, precise context. Supports creating and editing project documents (architecture summaries, design systems, test specs, etc.) via chat, with automatic injection during builds.
Build Orchestration & Observability Triggers builds per card or workflow, creating an isolated feature branch per attempt. The Agent Panel provides real-time visibility into agent activity, reasoning, and completion status, chaining agentic-flow execution, runtime status checks, and PR lifecycle management.
Local-first & Agent-agnostic Design All product and runtime state is stored in local SQLite (~/.dossier/dossier.db) — data never leaves the machine (except for Anthropic API and GitHub connections). The agentic-flow abstraction layer supports multiple agent backends including Claude Code and Cursor. Supports direct use of local Claude MAX accounts.
Three-layer State Separation Architecture
- Product Structure layer (Product → Workflow → Feature Card hierarchy, rich context cards) → SQLite
- Workflow State layer (attempt status, agent logs, execution history) → SQLite
- Code State layer (branches, commits, file changes) → Git (one feature branch per attempt)
