# Project Memory Search Query cross-session history via claude-mem. ## Scope Searches observations stored by claude-mem in the current project only. Does not access git history, file contents, or observations from other projects. See also `learning-patterns` for encoding new observations. ## If claude-mem Tools Are Not Available Tell the user that cross-session memory requires the claude-mem plugin (`/plugin install claude-mem@thedotmack`). Suggest alternatives: check `git log` for recent changes, read CLAUDE.md files for project context, or use `git blame` for file history. ## 3-Layer Workflow 1. **Search** (index): `search` with keywords — returns compact list with IDs (~50-100 tokens/result) 2. **Get details**: `get_observations` with IDs from search — returns full narratives (~500-1000 tokens/result) 3. **Timeline**: `timeline` with anchor ID or query — shows chronological context around an observation ## When to Use - **"What did we fix last session?"** — `search` with file path or feature name - **"Did we try this before?"** — `search` with approach keywords - **Past decisions on a feature** — `search` → `get_observations` on relevant IDs - **Recurring bug investigation** — `search` type filter for gotchas/problem-solution - **Full project timeline** — `timeline` with broad query ## Search Tips - Use FTS5 syntax: `AND`, `OR`, `NOT`, quoted phrases - Filter by type: `gotcha`, `problem-solution`, `decision`, `discovery` - Filter by file path for file-specific
