Copilot History Ingest — Conversation Mining

You are extracting knowledge from the user's past GitHub Copilot CLI conversations and distilling it into the Obsidian wiki. Conversations are rich but messy — your job is to find the signal and compile it.

This skill can be invoked directly or via the wiki-history-ingest router (/wiki-history-ingest copilot).

Before You Start

1. Resolve config — follow the Config Resolution Protocol in llm-wiki/SKILL.md (walk up CWD for .env → ~/.obsidian-wiki/config → prompt setup). This gives OBSIDIAN_VAULT_PATH, COPILOT_HISTORY_PATH (defaults to ~/.copilot/session-state), and COPILOT_VSCODE_STORAGE_PATH (VS Code workspaceStorage; platform-specific — ask the user if absent)
2. Read .manifest.json at the vault root to check what's already been ingested
3. Read index.md at the vault root to know what the wiki already contains

Ingest Modes

Append Mode (default)

Check .manifest.json for each source file (events JSONL, transcript JSONL, checkpoint, session-store DB). Only process:
