Hippo Memory
Manage long-term project memory across sessions with automatic decay and error retention.
Installation
- Make sure Claude is on your device and in your terminal.
Skills load from
~/.claude/skills/when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then runclaudein any terminal to verify.One-time setupnpm i -g @anthropic-ai/claude-codeAlready have it? Skip ahead.
- Paste into Claude Code or into your terminal.
This copies the whole skill folder into
~/.claude/skills/memory-kitfunso/— the SKILL.md plus any scripts, reference docs, or templates the skill ships with. Safe default: works for every skill.Faster alternative (instruction-only skills)
Skips the clone and grabs only the SKILL.md file. Don't use this if the skill ships Python scripts, reference markdowns, or asset templates — they won't be downloaded and the skill will fail when it tries to load them.
Quick install (SKILL.md only)Sign up to copy - Restart Claude Code.
Quit and reopen Claude Code (or any other agent that loads from
~/.claude/skills/). New skills are picked up on startup. - Just ask Claude.
Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.

When Claude uses it
Project memory powered by Hippo. Use when starting a session, after learning something, after hitting an error, or when the user mentions memory/remember/recall. Auto-invoked at session start.
What this skill does
Hippo Memory
Make your agent's memory work like a brain. Hippo is long-term memory for coding agents. Memories decay over time unless retrieved. Errors stick longer. Sleep consolidates.
At session start (MANDATORY)
Before doing any work, load relevant context:
hippo context --auto --budget 1500
Read the output. These are things the project has learned from past sessions.
When you learn something non-obvious
hippo remember "<the lesson in 1-2 sentences>" --tag <category>
When you hit an error or unexpected failure
hippo remember "<what failed, why, and how you fixed it>" --error
The --error flag doubles the half-life. Hard lessons don't fade quietly.
After completing work successfully
hippo outcome --good
If the recalled memories were irrelevant:
hippo outcome --bad
When stuck or hitting repeated errors
hippo recall "<what's going wrong>" --budget 2000 --why
When making an architectural decision
hippo decide "<decision>" --context "<why>"
Decisions get a recall boost so they surface when relevant, and stay active until superseded.
When migrating or replacing a tool
hippo invalidate "<old tool>" --reason "migrated to <new tool>"
Or let hippo learn --git detect it automatically from migration commits.
After significant coding sessions
hippo learn --git
This scans recent commits, auto-extracts lessons, and invalidates memories about replaced tools.
Export memories
hippo export memories.json
hippo export --format markdown memories.md
