ShareMemory Skill

Sets up and maintains a file-based shared memory (AI_MEMORY/) that Claude Code and Codex both read/write in the same project, so each agent sees the other's decisions and changes.

This skill is installable on both platforms (same folder, same SKILL.md):

• Claude Code: ~/.claude/skills/share-memory/ (personal) or <project>/.claude/skills/share-memory/ (project)
• Codex: ~/.agents/skills/share-memory/

AGENT_NAME: use Claude when running as Claude Code, Codex when running as Codex. After init, the rules live in the project's MEMORY_PROTOCOL.md — that file (not this skill) is the source of truth for day-to-day behavior.

Memory model:

• SYNC_LOG.md + archive/ are daily handoff history, with at most one block per date.
• PROJECT.md, DECISIONS.md, TASKS.md, and LEARNINGS.md are current views.
• Boot layer: AGENTS.md carries the shared agent-neutral rules; CLAUDE.md imports it via @AGENTS.md and adds Claude-only notes. All skill-managed boot content lives inside <!-- SHAREMEMORY:START --> / <!-- SHAREMEMORY:END --> marker blocks.
• Before ANY write inside AI_MEMORY/ (incl. creating or archiving files), acquire AI_MEMORY/.write.lock per the protocol.

Determine the operation from the user's intent: init, update, status, consolidate, repair, or migrate.
