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

Writing profile: Before drafting or rewriting natural-language Markdown, read and apply the Writing Profile Resolution section in llm-wiki/SKILL.md. Framework schema, provenance, safety, and operation-specific requirements take precedence. WRITING.md preferences apply only to newly drafted or rewritten natural-language Markdown; preserve source content and structured records.

1. Resolve config, follow the Config Resolution Protocol in llm-wiki/SKILL.md (inline @name override → walk up CWD for .env → global 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:

• Sessions not in the manifest (new sessions)
• Sessions whose updated_at is newer than their ingested_at in the manifest

This is usually what you want, the user ran a few new sessions and wants to capture the delta.

Full Mode

Process everything regardless of manifest. Use after a wiki-rebuild or if the user explicitly asks.

GitHub Copilot Data Layout

Copilot stores data in three locations. Scan all three.

Source 1: ~/.copilot/session-state/ (CLI sessions)
