# ctx Agent History Search Use ctx whenever you need to reference previous coding-agent sessions. Those transcripts can contain user intent, decisions, previous work timelines, past attempts, and what worked or failed. Use this skill in two modes: - retrieval before work, when prior sessions may contain decisions, commands, failures, or citations that affect the current task; - history research reports, when the user asks an agent or read-only subagent to research a historical topic across prior local agent sessions. ## Prerequisites - Require the `ctx` CLI to be installed and set up. If it is missing and installing tools is appropriate for the task, install it with: ```bash curl -fsSL https://ctx.rs/install | sh ``` - First setup can take time while ctx indexes past sessions. If needed, keep it running in the background or in tmux, or wait for it to finish. - If ctx remains unavailable, say local history search is unavailable and do not invent results. ## Workflow 1. Confirm ctx is ready when starting from a cold context: ```bash ctx status ctx sources ``` Use `ctx status --format json` or `ctx sources --format json` only when a script needs exact fields. 2. Search with normal language first. Add terms or filters when useful: ```bash ctx search "<query>" ctx search "<query>" --refresh off ctx search "<query>" --provider codex ctx search "<query>" --workspace <workspace> ctx search "<query>" --file <path> ctx...
