Agents consistently ignore written instructions about memory routing
and default to writing local MEMORY.md files regardless of rules in
RUNTIME.md, CLAUDE.md, or MEMORY.md itself. Instructions alone are
insufficient — a technical gate is required.
Changes:
- Add tools/qa/prevent-memory-write.sh — PreToolUse hook that blocks
Write/Edit/MultiEdit to ~/.claude/projects/*/memory/*.md (exit 2)
- Register hook in runtime/claude/settings.json PreToolUse array
- Update runtime/claude/RUNTIME.md: replace soft "Memory Override"
note with hard-gate policy, what-goes-where table, and rationale
- Rewrite guides/MEMORY.md: OpenBrain as primary layer, blocked silos
table, project continuity files, how-the-hook-works section
The correct behavior is now the only possible behavior for Claude Code.
All agent learnings route to OpenBrain where every harness can read them.
