What is common-memory-bank CLAUDE.md?

A set of instructions for AI coding tools that stores a project's goals, design, technology choices, and current work in organised memory files.

Use it to give tools such as Claude, Cursor, Windsurf, or Cline a shared project overview and continuing work context.

It helps an AI assistant recover project context between conversations instead of relying on one session's history. It also documents how task status should be managed with TaskMaster AI, a tool for tracking development tasks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00773	$0.00773
Opus 5.5	$0.00309	$0.00309
Sonnet 5.5	$0.00155	$0.00155
Haiku 4.5	$0.00077	$0.00077

Security

Grade A, and why

common-memory-bank CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

Common Memory Bank is a collection of integrated memory bank rules for AI development tools. It provides memory bank rule files that can be used across various AI development tools such as Cursor, Windsurf, Cline, RooCode, etc. It's specifically designed to work with TaskMaster AI for maintaining context across sessions.

Memory Bank Architecture

The Memory Bank follows a structured hierarchy with these core files:

memory-bank/
├── projectbrief.md       # Foundation document with core requirements and goals
├── productContext.md     # Product purpose, problems solved, user experience
├── systemPatterns.md     # System architecture, design patterns, technical decisions
├── techContext.md        # Technologies, development setup, technical constraints
└── activeContext.md      # Current focus, recent changes, next steps

When working with this project, always check the memory bank files first to understand the current state and context of the project.

TaskMaster Integration

This project is designed to work with TaskMaster AI. When using TaskMaster:

Always synchronize memory bank files with task status changes
Update activeContext.md whenever a task status changes
Check consistency between TaskMaster state and memory bank contents

Task Status Change Process

When changing a task status:

Change the task status with TaskMaster command (e.g., set_task_status)
Update activeContext.md to reflect the current task focus change
Update the next steps and considerations

Common Commands

TaskMaster Commands

# Initialize TaskMaster
task-master init

# Parse PRD to generate tasks
task-master parse-prd scripts/prd.txt

# Generate individual task files
task-master generate

# Show all tasks
task-master list

# Get next task
task-master next

# Set task status
task-master set-task-status <id> <status>

# Add a subtask
task-master add-subtask <id>

# Expand a task into subtasks
task-master expand-task <id>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
