| description | Ingest Codex CLI conversation history into the Obsidian wiki. Use this skill when the user wants to mine their past Codex sessions for knowledge, import their ~/.codex folder, extract insights from previous coding sessions, or says things like "process my Codex history", "add my Codex conversations to the wiki", or "what have I discussed in Codex before". Also triggers when the user mentions .codex sessions, rollout files, session_index.jsonl, or Codex transcript logs.

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
- Read
.env to get OBSIDIAN_VAULT_PATH and CODEX_HISTORY_PATH (default to ~/.codex if unset)
- 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
Ingest Modes
Append Mode (default)
Check .manifest.json for each source file. Only process:
- Files not in the manifest (new session rollouts, new index files)
- Files whose modification time is newer than
ingested_at in the manifest
Use this mode for regular syncs.
Full Mode
Process everything regardless of manifest. Use after wiki-rebuild or if the user explicitly asks for a full re-ingest.
Codex Data Layout
Codex stores local artifacts under ~/.codex/.
