Memory

Memory is a skill for Claude Code, Codex from llaa33219/casabot. It costs 14 tokens per session (1,455 once invoked), scanned A, original, Apache-2.0.

A manual for agents that explains how to save and retrieve important notes separately from automatically preserved conversation logs.

In plain words
What is it for?
Writing, updating, and querying agent memory, while leaving the original conversation history unchanged.
Why use it?
It prevents agents from treating raw session history as editable notes and provides a place to keep useful information for later work.

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

Memory 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 3d 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.

Memory

This manual explains the difference between History and Memory, and guides agents on how to write and query memos.


1. Difference between History and Memory

CasAbot has two storage systems. Make sure to use them correctly.

History — Conversation Logs

Item Description
Path ~/casabot/history/
Format JSON
Author System (auto-saved)
Editable ❌ Read-only
Purpose Raw logs of entire conversations
Contents User input, agent responses, tool call results, etc.

Memory — Agent Memos

Item Description
Path ~/casabot/memory/
Format Markdown (.md)
Author Agents (written directly)
Editable ✅ Freely editable
Purpose Record important information, learning outcomes, analysis results, etc.
Contents Things agents need to remember

Core Principles

  • Never modify History. It is preserved as the original conversation log.
  • Memory is freely written, modified, and deleted by agents. It is a space for organizing important information.
  • When important information comes up in conversation, record it in Memory.

2. Memory File Location

~/casabot/memory/
├── 2024-01-15-project-analysis.md
├── 2024-01-16-server-setup.md
├── user-preferences.md
├── frequently-used-commands.md
└── ...

3. Writing Rules

Filename Rules

  • With date (recommended): YYYY-MM-DD-topic.md — Record at a specific point in time
  • Without date: topic.md — Continuously updated record
  • Use alphanumeric characters and hyphens (-)
  • Use hyphens instead of spaces

File Format

All memory files are written in Markdown (.md) format.

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.

Memory is a skill published in the GitHub repository llaa33219/casabot (5 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 14 tokens to every session and 1,455 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-31.
