Memory

Overview

Memory provides persistent context across Claude Code sessions by storing and retrieving project decisions, user preferences, and coding conventions from a local JSON file. When a new session starts, stored memories load automatically so previously established patterns carry forward without re-explanation.

Prerequisites

• Project memory file at .claude/memories/project_memory.json (created automatically on first memory save)
• Read and Write permissions for the .claude/memories/ directory
• Claude Never Forgets plugin installed (/plugin install yldrmahmet/claude-never-forgets)

Instructions

1. Access stored memories. On session start, locate and read the memory file at .claude/memories/projectmemory.json using the Read tool. Parse the JSON structure containing timestamped memory entries. See ${CLAUDESKILL_DIR}/references/implementation.md for the full retrieval workflow.
2. Match memories to current context. Scan memory entries for keywords and topics relevant to the current task. Extract applicable decisions (e.g., "use pnpm instead of npm"), architectural patterns, library choices, and coding style preferences.
3. Apply memories silently. Incorporate remembered preferences into responses and tool usage without announcing them. When a memory dictates a package manager, testing framework, or naming convention, follow it automatically.
4. Store new memories. When significant decisions occur -- library selections, architectural choices, user-stated preferences, or tool rejections -- write them to the memory file with a timestamp. Add entries via the /remember command or through automatic capture of conversation signals.
5. Resolve conflicts. When a stored memory contradicts a current explicit request, prioritize the current request. Flag the conflict if appropriate and update the memory entry to reflect the new decision. Remove outdated memories that no longer apply.
6. Handle cleanup. When memory entries exceed 10, consolidate by removing noise (greetings, acknowledgments) and preserving high-value entries (preferences, decisions, corrections). The cleanup threshold is configurable in hooks/stop_cleanup.py.

Output

• Automatic loading of stored memories at session start
• Silent application of remembered preferences to tool usage and responses
• New memory entries written with timestamps for significant decisions
• Consolidated memory file after cleanup (preserves important entries, removes noise)
• Explicit memory listing via /memories command

Error Handling

Session 1:
You: "Use pnpm instead of npm for this project"
Claude: *uses pnpm*
→ Saved to memory

Session 2 (next day):
🧠 Loaded 3 memories
You: "Install axios"
Claude: *runs pnpm add axios*
→ Remembered your preference
