# Chat History - **IS:** recover historical context with source evidence: prior fixes, decision trails, exact passages and what followed, research across sessions. - **IS NOT:** browsing history, automatic memory writing, or proof of current repository or production state. For Obsidian notes use `obsidian`; for recent computer activity use an available computer-history capability. ## Agent compatibility The same skill and bundled script run in Codex, Grok, Cursor, and Claude Code. The model does not select the source adapter: every host can search every accessible supported source. No vendor SDK, host-specific tool names, or Claude-only substitutions are required. Read [host setup](references/hosts.md) when installing, moving between hosts, or diagnosing unavailable tools. ## Workflow 1. **Discover available evidence.** Resolve `scripts/history.py` relative to this installed SKILL.md, then execute it with `python3`. Run `discover` to report local source paths. Use explicit exports for web conversations; local Codex sessions do not include ChatGPT web history. Missing access is a coverage gap, not an empty search result. 2. **Search narrowly, widen deliberately.** Choose distinctive terms from the user's defect, artifact, project, or quoted passage. Start with known project/session paths; for cross-project research search the selected source roots. Batch spelling variants with repeated `-e` flags. Search results are literal OR matches in encounter order, not exhaustive or...
