Alex Newman d6cd9e6059 fix: implement pending_messages cleanup to prevent unbounded growth
Fixes #353 - Observations not being saved due to incomplete pending messages implementation

Changes:
- PendingMessageStore.markProcessed() now clears tool_input and tool_response
- PendingMessageStore.cleanupProcessed() changed from time-based to count-based retention
- Keeps most recent 100 processed messages for UI display
- SDKAgent.processSDKResponse() calls cleanup after marking messages processed

This prevents the database from growing unbounded with duplicate transcript data.
The pending_messages table now only stores full transcripts for pending/processing
messages, while processed messages keep metadata only.

Claude-Mem: AI Development Instructions

What This Project Is

Claude-mem is a Claude Code plugin providing persistent memory across sessions. It captures tool usage, compresses observations using the Claude Agent SDK, and injects relevant context into future sessions.

Architecture

5 Lifecycle Hooks: SessionStart → UserPromptSubmit → PostToolUse → Summary → SessionEnd

Hooks (src/hooks/*.ts) - TypeScript → ESM, built to plugin/scripts/*-hook.js

Worker Service (src/services/worker-service.ts) - Express API on port 37777, Bun-managed, handles AI processing asynchronously

Database (src/services/sqlite/) - SQLite3 at ~/.claude-mem/claude-mem.db with FTS5 full-text search

Search Skill (plugin/skills/mem-search/SKILL.md) - HTTP API for searching past work, auto-invoked when users ask about history

Chroma (src/services/sync/ChromaSync.ts) - Vector embeddings for semantic search

Viewer UI (src/ui/viewer/) - React interface at http://localhost:37777, built to plugin/ui/viewer.html

Privacy Tags

Dual-Tag System for meta-observation control:

  • <private>content</private> - User-level privacy control (manual, prevents storage)
  • <claude-mem-context>content</claude-mem-context> - System-level tag (auto-injected observations, prevents recursive storage)

Implementation: Tag stripping happens at hook layer (edge processing) before data reaches worker/database. See src/utils/tag-stripping.ts for shared utilities.

Build Commands

npm run build-and-sync        # Build, sync to marketplace, restart worker (most common)
npm run build                 # Compile TypeScript only
npm run sync-marketplace      # Copy to ~/.claude/plugins only
npm run worker:restart        # Restart worker service only
npm run worker:status         # Check worker status
npm run worker:logs           # View worker logs

Viewer UI: http://localhost:37777

Configuration

Settings are managed in ~/.claude-mem/settings.json. The file is auto-created with defaults on first run.

Core Settings:

  • CLAUDE_MEM_MODEL - Model for observations/summaries (default: claude-sonnet-4-5)
  • CLAUDE_MEM_CONTEXT_OBSERVATIONS - Observations injected at SessionStart
  • CLAUDE_MEM_WORKER_PORT - Worker service port (default: 37777)
  • CLAUDE_MEM_WORKER_HOST - Worker bind address (default: 127.0.0.1, use 0.0.0.0 for remote access)

System Configuration:

  • CLAUDE_MEM_DATA_DIR - Data directory location (default: ~/.claude-mem)
  • CLAUDE_MEM_LOG_LEVEL - Log verbosity: DEBUG, INFO, WARN, ERROR, SILENT (default: INFO)

File Locations

  • Source: <project-root>/src/
  • Built Plugin: <project-root>/plugin/
  • Installed Plugin: ~/.claude/plugins/marketplaces/thedotmack/
