Codex History Ingest — Conversation Mining

You are extracting knowledge from the user's past Codex sessions and distilling it into the Obsidian wiki. Session logs are rich but noisy: focus on durable knowledge, not operational telemetry.

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

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 and CODEX_HISTORY_PATH (defaults to ~/.codex)
2. Read .manifest.json at the vault root to check what has already been ingested
3. Read index.md at the vault root to understand what the wiki already contains
