Is the Memory Bank skill free?

Yes. The skill itself is free from fockus/skill-memory-bank. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Memory Bank SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install Memory Bank?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Memory Bank with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.6/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 53a0ca7

Copied the raw repo straight from GitHub with no installer, and `mb-init-bank.sh` / `mb-note.sh` / `mb-idea.sh` / `mb-search.sh` all worked immediately on a throwaway project, scaffolding a real structured `.memory-bank/` (status, roadmap, backlog with monotonic I-NNN ids, timestamped notes) that a plain 'write some notes' baseline can't match. README's '1,900+ automated tests' claim is actually conservative — repo has 2,275 bats + 1,542 pytest tests, and the 29-subagent count matches exactly.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Memory Bank does

Gives agents durable, git-tracked project memory in `.memory-bank/` (status/plan/checklist/backlog/lessons) plus an enforced engineering-rules baseline (TDD, SOLID, Clean Architecture, FSD) and 25+ `/mb` workflow commands. Triggers automatically in any project with a `.memory-bank/` directory, or when the user explicitly asks for a memory-bank workflow, engineering rules, or dev-toolkit commands.

How to install Memory Bank

git clone https://github.com/fockus/skill-memory-bank
mkdir -p ~/.claude/skills
cp -r skill-memory-bank ~/.claude/skills/memory-bank

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Memory Bank

/memory-bank Persistent .memory-bank/ project memory, TDD/Clean-Architecture rules, and a 25+ command dev toolkit.

It also activates on plain-language prompts like these:

Set up persistent project notes so agents remember context each time.
This project already has saved status notes, let's resume from there.
Log this feature idea into our project's backlog for later.
