memory

A file-based system for saving and searching project, user, feedback, and reference notes, with optional synchronisation to a semantic search store. It keeps these notes in Markdown files and maintains an index.

In plain words
What is it for?
Use it to save, update, delete, search, or re-index stored memories about a project, its preferences, instructions, or references.
Why use it?
It prevents useful context from being scattered across conversations or forgotten between tasks. It also supports checking for duplicate memories before saving new ones.

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 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.

How it starts

The opening of the file, as written. The whole thing — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Memory Skill

Purpose

Unified CRUD operations over the scaffolding memory system. Handles file-based markdown entries under ~/.claude/projects/.../memory/ and synchronises every write/delete with the MCP semantic vector store when available.

Use this skill when an explicit memory management action is requested: save a new entry, update or delete an existing one, query/search stored entries, or rebuild the MEMORY.md index.


Memory Types

Type File prefix Use for
user user_*.md Personal preferences, identity, recurring instructions
feedback feedback_*.md Corrections, tone/style adjustments, behavioural feedback
project project_*.md Stack details, environment facts, team conventions
reference reference_*.md External resources, URLs, credentials pointers

File Layout

~/.claude/projects/{project-slug}/memory/
├── MEMORY.md           ← index (one bullet per entry)
├── user_*.md           ← user-type entries
├── feedback_*.md       ← feedback-type entries
├── project_*.md        ← project-type entries
└── reference_*.md      ← reference-type entries

The project slug is the filesystem-safe version of the working directory path (hyphens replacing /, e.g. -home-komluk-repos).


Entry File Format

Every entry file MUST begin with YAML frontmatter followed by the body:

---
name: <kebab-case-slug>
description: "<one-line summary>"
metadata:
  node_type: memory
  type: <user|feedback|project|reference>
  originSessionId: <session-uuid-or-unknown>
---

<Body content — concise markdown. Max ~40 lines per file.>

**Why:** <rationale or context>

**How to apply:** <when/how to use this entry>

Rules:

  • name must be kebab-case and equal the file slug (after the prefix).
  • description is the single line shown in MEMORY.md.
  • Body MUST include Why and How to apply sections.
  • Do NOT store secrets, tokens, or passwords.

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 komluk/scaffolding (15 stars, last pushed 26d ago), licensed MIT. It adds 73 tokens to every session and 1,634 once invoked, about $0.0004 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.
