Why

Meeting Assistant should provide a meeting capture workflow that is not tied to a specific online meeting provider. The first version needs to establish the platform-independent core: meeting notes, metadata capture, transcription with speaker attribution, generated summaries and next steps, and a project knowledge base that agents can use for later retrieval and controlled project work.

What Changes

• Create Meeting Assistant as a .NET 10 server application in Manuel/meeting-assistant.
• Establish OpenSpec as the source of truth for behavior changes.
• Define the version 1 meeting flow around Obsidian markdown notes created before transcription starts.
• Require the core flow to support in-person meetings and not depend on Teams, Zoom, or similar APIs.
• Add a configurable global hotkey that toggles recording/transcription mode.
• Capture microphone input and computer output into one transcription audio stream.
• Require speech recognition pipelines to accept streamable audio, with FunASR configured for speaker-attributed transcription and local Whisper plus pyannote kept as a fallback pipeline.
• Store the live transcript in a text file under the configured vault folder.
• Add requirements for speaker-attributed transcription, summaries, decisions, and next steps.
• Define project context capture and retrieval as first-class capabilities.
• Define agent tools for project lookup and project file changes in existing projects.

Capabilities

New Capabilities

• meeting-session: creation and lifecycle of meeting notes and metadata.
• meeting-recording: hotkey-controlled recording mode, mixed audio capture, and transcript persistence.
• meeting-transcription: platform-independent transcription with speaker attribution.
• meeting-summary: generated summaries, decisions, and next steps.
• project-knowledge: project context, retrieval, and knowledge base updates from meetings.
• agent-project-tools: agent tools for lookup, retrieval, and project file updates.

Impact

• New .NET 10 solution, service project, tests, README, and OpenSpec structure.
• New recording/transcription services using configurable .NET options.
• NAudio is used for Windows microphone and WASAPI loopback capture.
• FunASR is used as the configured speaker-attribution pipeline, and Whisper.NET plus pyannote remains available as a local transcription fallback.
• Version 1 behavior is documented before feature implementation.
• Future platform integrations remain optional augmentations instead of hard dependencies.
