Codex History Ingest

This pulls your Codex CLI session history from ~/.codex and distills it into your Obsidian wiki. It parses rollout logs, session indexes, and transcripts, then clusters conversations by topic instead of dumping raw chronology. Smart about privacy by default: it redacts credentials, summarizes rather than quotes verbatim, and skips telemetry noise. The skill knows to look at session_index.jsonl first for inventory, then processes rollout files incrementally using a manifest. Works in append mode for daily syncs or full mode after rebuilds. Main value is surfacing patterns across sessions, like recurring debugging techniques or architectural decisions you made weeks ago, without manually rereading hundreds of JSONL events.

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.

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)
Read .manifest.json at the vault root to check what has already been ingested
Read index.md at the vault root to understand what the wiki already contains
