unicity-aos/capsule-memory

This system is a memory capsule component for an AI assistant that injects user preferences and project-specific context into system prompts. It operates using an event-driven publish/subscribe model to listen for prompt building events and retrieves memory data from configurable local file paths. The implementation ensures context stability by independently truncating personal and project memory sections to prevent context window overflow.

The memory capsule now reads and injects two distinct sources of context into the system prompt: personal memory from \home://memory.md\ (user preferences and long-term facts) and project memory from \cwd://{cwd\_dir}/memory.md\ (project-specific conventions and current work). The project memory path is determined by the \cwd\_dir\ environment variable, allowing distros to customize the project folder name without forking the code. Both sources are optional and silently skipped if missing or empty, with personal memory injected first followed by project memory. Each section is independently truncated to 32KB to prevent context window overflow, and a notice is added if truncation occurs.

src · high confidence

The astrid-capsule-memory component has been updated to version 0.2.0, introducing a new event-driven architecture and broader file system access. The component now uses a publish/subscribe schema (replacing the previous interceptor model) to listen for the \prompt\_builder.v1.hook.before\_build\ event and publish responses, ensuring compatibility with the latest WIT definitions. Additionally, the component's file read capabilities have been expanded from the workspace root to include \cwd://\ and \home://\ paths, allowing it to access memory files in the current working directory and home directory. The default project folder for memory storage is now configurable via the \cwd\_dir\ environment variable (defaulting to \.astrid\).

(repo-wide) · high confidence

The astrid-capsule-memory package has been updated to version 0.2.0, primarily driven by a significant upgrade of the astrid-sdk dependency from a local path reference (v0.1.1) to the crates.io registry (v0.7). This change resolves the SDK source to a specific published version and aligns with the project's move to enforce locked builds. Additionally, the release profile has been optimized for size with LTO, stripping, and panic abortion enabled, and the uuid dependency has been explicitly added with the rng-getrandom feature.
