copilot-history-ingest

Copilot-history-ingest captures a user's past GitHub Copilot CLI session history and distills it into an Obsidian wiki as searchable knowledge pages — extracting architecture decisions, debug notes, and reusable patterns from conversations that are rich but messy. It solves the problem of valuable engineering context being locked inside ephemeral Copilot sessions by mining that history and compiling the signal into a personal knowledge base.

The skill resolves configuration (vault path and Copilot history locations) through a defined protocol, then reads a manifest and index to know what already exists. It supports an append mode (default) that only processes new or updated sessions using timestamps, and a full mode that reprocesses everything. It scans three Copilot data locations: the per-session `session-state` directories (workspace metadata, event logs, checkpoints, session summaries), the global `session-store.db` SQLite database (the highest-value, pre-summarized cross-session record with sessions, turns, checkpoints, file references, and a full-text search index), and VS Code workspace storage transcripts. A detailed reference documents each event type and, importantly, an extraction strategy that deliberately skips encrypted/opaque and internal reasoning fields, using only visible content and structured checkpoint summaries.

It targets individual developers who use Copilot CLI and maintain an Obsidian vault and want an automated, incremental way to turn their session history into durable notes. Behaviorally it reads local session data (including SQLite databases and JSONL logs) and writes markdown into a local vault — no network exfiltration — and it is conscious about not surfacing encrypted internal reasoning.
