Kjell Tore Guttormsen 2491f5c732 feat: initial companion repo for OpenClaw vs Claude Code article 
40 files demonstrating every major OpenClaw capability using Claude Code:
- 3 agents (researcher, writer, reviewer)
- 3 skills (daily-briefing, slack-message, web-research)
- 2 security hooks (pre-tool-use blocker, post-tool-use logger)
- 10 self-contained examples with copy-paste prompts
- Complete feature map (20 capabilities, 11 full match, 7 different, 2 gap)
- Security docs including NemoClaw comparison
- Automation, messaging, browser, memory documentation

Zero dependencies. Clone and run.

Memory System

How Claude Code and OpenClaw handle cross-session persistence.

Claude Code: File-based memory

Claude Code reads files at session start and writes them back on request.

Mechanism:

  • CLAUDE.md files at ~/.claude/CLAUDE.md (global), repo root, and subdirectories
  • Auto-memory: files listed in CLAUDE.md under memory: are auto-loaded
  • Project files: any file you explicitly tell Claude to read at session start
  • No background process, no indexing, no database

Properties:

  • Deterministic: Claude reads exactly what you wrote
  • No semantic search: retrieval is positional, not by meaning
  • Fully transparent: open any file to see what Claude knows
  • Hierarchical: global < project < subdirectory, each level can override

OpenClaw: Hybrid memory

OpenClaw maintains memory through a combination of structured logs and vector search.

Mechanism:

  • Daily markdown logs with structured entries
  • MEMORY.md as a curated summary file
  • SQLite-vec or LanceDB for vector storage
  • BM25 + cosine similarity for retrieval (hybrid search)

Properties:

  • Semantic search: "find notes about authentication" works even without exact keywords
  • Automatic logging: entries written by the agent during execution
  • Higher complexity: requires a running database
  • Retrieval can surface relevant context not explicitly linked

Comparison

Property Claude Code OpenClaw
Storage Plain files Files + SQLite/LanceDB
Retrieval Positional/explicit BM25 + cosine (hybrid)
Semantic search No Yes
Setup complexity Zero Moderate
Transparency Full Partial
Cross-session Yes (manual) Yes (automatic)

Recommendation

For most projects, Claude Code's file-based approach is sufficient. Keep MEMORY.md short and curated. Long files degrade quality faster than missing context does.

Use this directory (memory/) to store any project state that should outlast a session.
