memory-system

A project-memory system that stores important information in seven files arranged across three levels. It keeps active context and summaries readily available, while loading architecture, components, decisions, and logs only when needed.

In plain words
What is it for?
Use it to retain project context, support coding and debugging work, and automatically save useful information after tasks finish.
Why use it?
It helps an agent continue work across sessions without rereading every project file or losing important decisions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-system 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.

🧠 Memory System Skill

Purpose: Tiered, low-token memory — load only what the task needs, save what matters Version: 2.0.0 For: Toh Framework v2.0.0+ Updated: 2026-07-14


Overview

Automatic memory that keeps AI in context across sessions with zero user effort. v2 replaces the old "read all files every time" mandate with tiered loading: Tier 1 is always read (~800 tokens), Tier 2 is read only for the relevant task type, Tier 3 only when explicitly referenced.

Key principles

  • Zero config — no setup required
  • Tiered — Tier 1 always; Tier 2/3 on demand (no more ~3,000 tokens every time)
  • Auto save — saves after task completion, never asks the user
  • Delegated agents don't re-read — they receive context from the orchestrator
  • IDE & model agnostic

📚 The Tiered Model (use this everywhere)

There are 7 memory files across 3 tiers. Read by tier, not all at once.

Tier Files When to read Budget
Tier 1 active.md + summary.md ALWAYS, at every session start ~800 tokens
Tier 2 architecture.md + components.md Build / code work (creating pages, components, logic) ~600 tokens
Tier 2 changelog.md Debug work (to see previous attempts) ~400 tokens
Tier 3 decisions.md + agents-log.md Only when explicitly referenced / asked about on demand

This replaces the old "read ALL files (MANDATORY)" rule. Never bulk-read all 7. Read Tier 1 always, add the Tier 2 files that match the task type, and touch Tier 3 only when needed.

Delegated agents: an agent invoked by the orchestrator receives context from the orchestrator and does NOT re-read memory itself. This avoids every agent re-reading the same files.

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

memory-system is a skill published in the GitHub repository wasintoh/toh-framework (95 stars, last pushed 6d ago), licensed MIT. It adds 114 tokens to every session and 2,033 once invoked, about $0.0006 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 2026-08-30.
