core-memory-kit CLAUDE.md

core-memory-kit CLAUDE.md is an instructions file for coding agents from LH8PPL/core-memory-kit. It costs 26,397 tokens per session, scanned D, original, MIT.

A project-specific memory system for Claude Code that stores durable facts in Markdown files inside and alongside a code repository.

In plain words
What is it for?
Use it to preserve project decisions, facts, architecture notes, terminology, and working context across sessions.
Why use it?
It reduces the loss of project knowledge between separate AI coding sessions.

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 D, and why

core-memory-kit CLAUDE.md scanned grade D with 2 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

core-memory-kit — project CLAUDE.md

Auto-loaded by Claude Code at session start when this repo is the primary workspace. Read in full before responding to the user.

What this project is

A per-project, in-repo memory system for Claude Code. Fixes per-session amnesia by storing durable facts as markdown inside <repo>/context/ (committed) + <repo>/context.local/ (gitignored) + ~/.core-memory-kit/ (user-tier). Architecture-first v0.1 (~50 dev-days, 36 tasks). Not Cursor's MVP shape — we're laying foundations first.

Read these in order (10 minutes total)

  1. docs/journey/build-log.md — full narrative. The single most important doc.
  2. docs/SYSTEM-MAP.md — the kit as ONE system: whole + parts + the relationship edges, the TARGET learn-loop design ("our Figure 2", §6), and the anti-decomposition guard (§7). Read before any architecture-level thinking or decision — it holds what the structural docs decompose away.
  3. specs/tasks.md — the 44-task build plan. Find the next [ ] parent task.
  4. specs/glossary.md — domain terms. When two docs disagree, glossary wins.
  5. specs/design.md — HOW the kit works (skim, then read sections as needed).
  6. specs/requirements.md — WHAT v0.1.0 must do (FR-, NFR-).

Working style (locked in by the user)

The user is direct and tight on time. Match the energy.

Tone:

  • Terse, direct responses. No filler ("Great question!", "Sure thing!", "I'd love to help!").
  • Lead with the answer. Add context only if it changes the answer.
  • "go" = start the next task immediately, no preamble.
  • "lets continue" / "let's continue with X" = same — execute.
  • Acknowledge mistakes plainly. Don't bury them in apology. "I was wrong about X. Here's the fix."

Decisions:

  • One recommendation > four options. State a choice; user redirects if wrong.
  • Use AskUserQuestion only for genuine forks where you can't pick. Don't over-use it for things you should just decide.
  • When asked for opinions, give a real opinion. Don't equivocate.

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.
