Stores project tasks as markdown files in .knowns/tasks/ directory with Git-friendly format, enabling AI agents to maintain persistent memory across sessions. Tasks include acceptance criteria, implementation plans, and @doc/path/@task-N references that create a context graph. When an AI agent is assigned a task, it parses all embedded references, recursively follows links to documentation, and builds a complete context graph before implementation — solving the stateless AI problem where context must be re-explained each session.
Unique: Uses Git-tracked markdown files with @reference syntax for context linking instead of a centralized database, making the entire knowledge base human-readable, version-controlled, and portable. The reference resolution happens at read-time (when AI agent accesses a task) rather than at write-time, enabling dynamic context graphs that adapt as documentation changes.
vs alternatives: Unlike Jira or Linear which store context in proprietary databases, knowns makes task context Git-trackable and AI-readable; unlike simple markdown folders, it provides structured reference linking and recursive context resolution for AI agents.
Implements a Model Context Protocol (MCP) server that exposes the task and documentation system to AI agents via standardized protocol bindings. When an AI agent connects via MCP, it can query tasks, resolve references, and retrieve full context graphs without parsing markdown directly. The MCP server translates internal FileStore operations into MCP resource and tool endpoints, enabling seamless integration with Claude, GPT, and other MCP-compatible agents.
Unique: Implements MCP as a first-class integration point rather than an afterthought, making the entire task/doc system queryable via standard protocol. The MCP server translates FileStore operations into protocol-native endpoints, enabling AI agents to resolve context graphs without understanding knowns' internal markdown structure.
vs alternatives: Provides standardized MCP integration vs. custom API endpoints; enables any MCP-compatible agent to access context without custom adapters; follows protocol standards for interoperability.
Implements knowns as a TypeScript codebase that compiles to JavaScript and runs on Node.js, Deno, and browser runtimes. The build system uses Vite for bundling and supports multiple entry points (CLI, server, web UI). Core logic is runtime-agnostic, with platform-specific adapters for file I/O, HTTP, and other system operations. This enables the same codebase to run as a CLI tool, HTTP server, web application, and embedded library.
Unique: Implements a single TypeScript codebase with runtime-agnostic core logic and platform-specific adapters, enabling deployment as CLI, server, and web application without code duplication. Vite-based build system supports multiple entry points and targets.
vs alternatives: More flexible than single-runtime tools (CLI-only or server-only); enables code reuse across platforms; simpler than maintaining separate implementations for each runtime.
Provides a React-based web interface that renders the same task and documentation data as the CLI. The web UI includes a Kanban board for visual task management, a documentation browser for exploring linked docs, and a task detail view with full context. The UI communicates with the knowns server via HTTP API and WebSocket for real-time updates. All UI state is derived from the FileStore, ensuring consistency with CLI and other interfaces.
Unique: Implements web UI as a separate React application that communicates with knowns server via standard HTTP API and WebSocket, rather than embedding UI logic in the server. This enables independent UI updates and scaling.
vs alternatives: Lighter than Jira/Linear UI (no complex state management) but more polished than plain CLI; provides visual overview for non-technical stakeholders while maintaining CLI-first developer experience.
Parses @doc/path and @task-N reference syntax embedded in task descriptions and documentation, then recursively resolves all linked documents to build a complete context graph. When an AI agent requests a task, the system traverses the reference tree, fetches all linked documentation, and returns a flattened context structure. This enables AI agents to understand not just the immediate task but all architectural decisions, patterns, and related work that inform implementation.
Unique: Uses a simple @reference syntax embedded directly in markdown rather than a separate link database, making references human-readable and editable. Resolution happens at read-time with recursive traversal, enabling dynamic context graphs that adapt as documentation changes without requiring index updates.
vs alternatives: Simpler than graph database approaches (no schema, no query language) but more powerful than flat document lists; enables AI agents to discover context through reference chains rather than requiring explicit context specification.
Provides a command-line interface (knowns/kn commands) for creating, updating, and organizing tasks and documentation with built-in Kanban board state management. Tasks move through predefined states (backlog, in-progress, review, done) tracked in markdown frontmatter. The CLI supports batch operations, filtering, and status transitions. A companion web UI (React-based) renders the same data as a visual Kanban board, with both interfaces operating on the shared .knowns/ file store.
Unique: Implements a dual-interface design where CLI and web UI operate on the same file-based storage, avoiding database synchronization issues. Kanban state is stored in markdown frontmatter, making workflow status Git-trackable and mergeable.
vs alternatives: Lighter than Jira/Linear (no server, no database) but more structured than plain markdown folders; CLI-first design appeals to developers while web UI provides visual overview for non-technical stakeholders.
Maintains a version history of all task and documentation changes using a VersionStore layer that tracks file mutations over time. Each change is recorded with timestamp and metadata, enabling rollback to previous states. The versioning system operates transparently on top of the FileStore, capturing all mutations whether they come from CLI, web UI, or API calls. This enables audit trails and recovery from accidental deletions or edits.
Unique: Implements versioning at the FileStore layer (below CLI/web UI) rather than as a separate feature, capturing all mutations regardless of interface. Version history is stored alongside data files, making it portable and Git-compatible.
vs alternatives: Provides version history without relying on Git commits; enables rollback without understanding Git; simpler than full Git integration but less powerful than Git's branching model.
Stores project documentation as markdown files in .knowns/docs/ with YAML frontmatter for metadata (title, tags, created, updated). Documentation supports standard markdown syntax plus knowns-specific reference syntax (@doc/path, @task-N) for linking to other docs and tasks. The system treats documentation as first-class entities that can be queried, linked, and versioned alongside tasks. A documentation browser in the web UI enables visual navigation of the doc structure.
Unique: Treats documentation as first-class entities with structured metadata and reference linking, rather than as unstructured markdown files. Documentation is queryable, linkable, and versionable alongside tasks, creating a unified knowledge system.
vs alternatives: Simpler than wiki systems (no database, no special syntax) but more structured than plain markdown folders; enables AI agents to discover and link documentation through reference chains.

Processes natural language questions about code within a sidebar chat interface, leveraging the currently open file and project context to provide explanations, suggestions, and code analysis. The system maintains conversation history within a session and can reference multiple files in the workspace, enabling developers to ask follow-up questions about implementation details, architectural patterns, or debugging strategies without leaving the editor.
Unique: Integrates directly into VS Code sidebar with access to editor state (current file, cursor position, selection), allowing questions to reference visible code without explicit copy-paste, and maintains session-scoped conversation history for follow-up questions within the same context window.
vs alternatives: Faster context injection than web-based ChatGPT because it automatically captures editor state without manual context copying, and maintains conversation continuity within the IDE workflow.
Triggered via Ctrl+I (Windows/Linux) or Cmd+I (macOS), this capability opens an inline editor within the current file where developers can describe desired code changes in natural language. The system generates code modifications, inserts them at the cursor position, and allows accept/reject workflows via Tab key acceptance or explicit dismissal. Operates on the current file context and understands surrounding code structure for coherent insertions.
Unique: Uses VS Code's inline suggestion UI (similar to native IntelliSense) to present generated code with Tab-key acceptance, avoiding context-switching to a separate chat window and enabling rapid accept/reject cycles within the editing flow.
vs alternatives: Faster than Copilot's sidebar chat for single-file edits because it keeps focus in the editor and uses native VS Code suggestion rendering, avoiding round-trip latency to chat interface.

Copilot can generate unit tests, integration tests, and test cases based on code analysis and developer requests. The system understands test frameworks (Jest, pytest, JUnit, etc.) and generates tests that cover common scenarios, edge cases, and error conditions. Tests are generated in the appropriate format for the project's test framework and can be validated by running them against the generated or existing code.
Unique: Generates tests that are immediately executable and can be validated against actual code, treating test generation as a code generation task that produces runnable artifacts rather than just templates.
vs alternatives: More practical than template-based test generation because generated tests are immediately runnable; more comprehensive than manual test writing because agents can systematically identify edge cases and error conditions.
When developers encounter errors or bugs, they can describe the problem or paste error messages into the chat, and Copilot analyzes the error, identifies root causes, and generates fixes. The system understands stack traces, error messages, and code context to diagnose issues and suggest corrections. For autonomous agents, this integrates with test execution — when tests fail, agents analyze the failure and automatically generate fixes.
Unique: Integrates error analysis into the code generation pipeline, treating error messages as executable specifications for what needs to be fixed, and for autonomous agents, closes the loop by re-running tests to validate fixes.
vs alternatives: Faster than manual debugging because it analyzes errors automatically; more reliable than generic web searches because it understands project context and can suggest fixes tailored to the specific codebase.
Copilot can refactor code to improve structure, readability, and adherence to design patterns. The system understands architectural patterns, design principles, and code smells, and can suggest refactorings that improve code quality without changing behavior. For multi-file refactoring, agents can update multiple files simultaneously while ensuring tests continue to pass, enabling large-scale architectural improvements.
Unique: Combines code generation with architectural understanding, enabling refactorings that improve structure and design patterns while maintaining behavior, and for multi-file refactoring, validates changes against test suites to ensure correctness.
vs alternatives: More comprehensive than IDE refactoring tools because it understands design patterns and architectural principles; safer than manual refactoring because it can validate against tests and understand cross-file dependencies.
Copilot Chat supports running multiple agent sessions in parallel, with a central session management UI that allows developers to track, switch between, and manage multiple concurrent tasks. Each session maintains its own conversation history and execution context, enabling developers to work on multiple features or refactoring tasks simultaneously without context loss. Sessions can be paused, resumed, or terminated independently.
Unique: Implements a session-based architecture where multiple agents can execute in parallel with independent context and conversation history, enabling developers to manage multiple concurrent development tasks without context loss or interference.
vs alternatives: More efficient than sequential task execution because agents can work in parallel; more manageable than separate tool instances because sessions are unified in a single UI with shared project context.
Copilot CLI enables running agents in the background outside of VS Code, allowing long-running tasks (like multi-file refactoring or feature implementation) to execute without blocking the editor. Results can be reviewed and integrated back into the project, enabling developers to continue editing while agents work asynchronously. This decouples agent execution from the IDE, enabling more flexible workflows.
Unique: Decouples agent execution from the IDE by providing a CLI interface for background execution, enabling long-running tasks to proceed without blocking the editor and allowing results to be integrated asynchronously.
vs alternatives: More flexible than IDE-only execution because agents can run independently; enables longer-running tasks that would be impractical in the editor due to responsiveness constraints.
Provides real-time inline code suggestions as developers type, displaying predicted code completions in light gray text that can be accepted with Tab key. The system learns from context (current file, surrounding code, project patterns) to predict not just the next line but the next logical edit, enabling developers to accept multi-line suggestions or dismiss and continue typing. Operates continuously without explicit invocation.
Unique: Predicts multi-line code blocks and next logical edits rather than single-token completions, using project-wide context to understand developer intent and suggest semantically coherent continuations that match established patterns.
vs alternatives: More contextually aware than traditional IntelliSense because it understands code semantics and project patterns, not just syntax; faster than manual typing for common patterns but requires Tab-key acceptance discipline to avoid unintended insertions.
