Why it matters

🔁
Stop re-explaining
Every session starts cold. Stack, conventions, ongoing work, past decisions — gone. Elephant loads that context automatically.
📝
Changelogs write themselves
No more release-day archaeology. Semver-aware bump dialog, categorized entries, synced README badge.
👥
Team memory
ELEPHANT.md gets committed. Every teammate, every clone, same context — with @author attribution on every entry.
🌍
Cross-repo
A global memory at ~/.claude/elephant/memory.md keeps context across every project you work on. Switch repos, keep the thread.
⚡
~150 tokens of history
Caveman compression + compact = a full week of project context in ~150 tokens. vs. 500+ tokens of manual preamble.
🚀
Instant cold start
New machine, fresh clone, new teammate. /elephant takeover seeds memory from 60 commits in seconds.

How it works

📁
Just a file
Memory lives in ELEPHANT.md at the repo root. Readable, editable, committable. Share it with your team.
☁️
No cloud
Nothing leaves your machine. No API keys beyond your Claude subscription.
🗜️
Token-efficient
Caveman compression strips articles and filler. Compact merges old entries. History stays lean automatically.
