remember

A command for adding important project information to a long-term memory file named REMEMBER.md. It sorts the information into sections such as setup, architecture, constraints, and lessons learned.

In plain words
What is it for?
Use it to record project structure, development setup, standards, dependencies, constraints, goals, and lessons learned in the appropriate section.
Why use it?
It prevents useful project decisions and facts from being lost between work sessions or buried in conversation history.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 337 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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.

Security

Grade A, and why

remember 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 2d 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.

What it actually says

You are helping add important information to the project's long-term memory system.

Context

The user wants to add this information to .claude/flashback/memory/REMEMBER.md: "$ARGUMENTS"

Current REMEMBER.md Content

{{CURRENT_MEMORY}}

Task

Analyze the user's input and add it to the appropriate section in .claude/flashback/memory/REMEMBER.md. The information should be:

  1. Categorized correctly - Place it in the most relevant section:

    • 📋 Project Overview - For high-level project description
    • 🏗️ Architecture & Patterns - For design decisions and architectural info
    • 🔧 Development Setup - For setup, dependencies, configuration
    • 📝 Conventions & Standards - For code style and project standards
    • 🚨 Important Constraints - For limitations, requirements, things to avoid
    • 🔗 Key Dependencies - For important libraries, frameworks, services
    • 📁 Directory Structure - For file locations and organizational patterns
    • 🧠 Lessons Learned - For insights, gotchas, knowledge gained
    • 🎯 Current Goals - For high-level objectives and current work
  2. Well-formatted - Use consistent formatting with existing content

  3. Concise but complete - Capture the essential information clearly

  4. Actionable - Make it useful for future sessions

If the input doesn't clearly fit existing sections, add it to "🧠 Lessons Learned" as the default.

Please output the complete updated .claude/flashback/memory/REMEMBER.md file with the new information properly integrated.

Changes

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.

remember is a command published in the GitHub repository agentsea/flashbacker (57 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 337 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
