+title: Deep Session Search
+description: An OpenClaw skill for recovering prior context from session logs when memory is incomplete.
+---
+
+This skill helps recover decision context (domains, PRs, deploys, commands, and error trails) from historical OpenClaw sessions when those details were discussed but never promoted into long-term memory files.
+
+## Why this exists
+
+Sometimes important details are discussed in earlier sessions but never distilled into `MEMORY.md` or daily notes.
+
+This skill gives the agent a reliable fallback path:
+
+1. Try normal memory recall first.
+2. If recall is missing/unclear, search session logs under `~/.openclaw/agents/main/sessions`.
+3. Extract high-signal conversation/tool evidence without dumping noisy artifacts.
+
+## What it does
+
+- **Deep session grep** over `*.jsonl*` logs
+- **Noise control** to avoid dependency/build blobs
+- **Targeted narrowing** by exact domain, PR number, repo, deployment id, etc.
+- **Evidence-first summaries** with path + relevant context
+
+## Typical trigger
+
+Use when the user asks things like:
+
+- “What did we do with Cloudflare today?”
+- “Check earlier sessions for that domain/config”
+- “Find the command we used before”
+
+…especially when memory search has low confidence.
+
+## Search pattern
+
+Prefer `ag` for fast uncompressed session log scans:
+
+```bash
+ag -n --nobreak --depth 1 -G '*.jsonl' "<search-term-1>|<search-term-2>" \
+  ~/.openclaw/agents/main/sessions
+```
+
+For compressed/rotated logs, use one of these:
+
+```bash
+# ripgrep with compressed-file support
+rg -n --search-zip --max-depth 1 "<search-term-1>|<search-term-2>" \
+  ~/.openclaw/agents/main/sessions -g '*.jsonl*'
+
+# or gzip-specific fallback
+find ~/.openclaw/agents/main/sessions -maxdepth 1 -name '*.jsonl.gz' \
+  -exec zgrep -HnE "<search-term-1>|<search-term-2>" {} +
+```
+
+Note: these examples use regex patterns. If your search terms are literals (like domains), either escape regex special characters or use fixed-string modes (for example: `ag -Q`, `rg -F`, `zgrep -F`).
+
+Then narrow to exact needles for stronger evidence.
+
+## Outcome format
+
+The skill returns concise findings with:
+
+- whether hits were found
+- strongest 1–3 examples
+- where they were found (path/context)
+- confidence note if results are partial/noisy
