memory

memory is a skill for Claude Code from Muuuun/luxas. It costs 24 tokens per session (545 once invoked), scanned A, original, MIT.

A cross-project research memory system for finding notes from earlier research projects and saving lessons that apply across projects. Information from past projects is treated as an unverified lead until checked against current evidence.

In plain words
What is it for?
Use it to inspect past project notes, check existing papers and experiments, record corrections, and save decisions or lessons for future research.
Why use it?
It helps you reuse earlier findings without confusing old notes with confirmed results or overlooking recorded corrections.

About the project

Luxas is an open-source multi-agent research system that takes a research topic through literature searches, experiments, reviews, and LaTeX manuscript compilation. It is intended for autonomous scientific research, using separate agents to read papers, run tests, create figures, and write reports. The catalogue lists skills associated with this workflow.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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 6d 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.

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Memory Skill

Access persistent memory that spans across research projects.

You do not need this skill to discover past projects — your system prompt already carries a <past_research> digest (every past project's name, date, notes path, and research question). This skill is for what comes after discovery: deep-diving a relevant project's notes and recording corrections.

Trust rule

Everything read from a past project is a dated, UNVERIFIED lead — not established fact. Values must re-enter the current project's own evidence chain (reader-distilled literature, this project's experiments) before they appear in report.tex. Honor ## CORRECTIONS sections wherever you find them.

Files

Past project notes (primary source)

The <past_research> digest lists each project's live notes path:

<path>/notes/experiments.md   ← findings, alternatives, limitations, red-team
<path>/notes/literature.md    ← reader-distilled per-paper entries
<path>/notes/memory.md        ← decisions, dead ends, TODOs
<path>/data/papers/           ← downloaded PDFs (check before re-downloading)

~/.sisyphus/projects.json

Project registry (path, name, dates, auto-generated summary, cost). The digest is built from this; read it directly only for projects that fell into the digest's overflow index.

~/.sisyphus/archive//

Auto-archived copies of each project's notes + report.tex, written when a run completes. Fallback when the live project dir is gone.

CORRECTIONS convention

When you find that a past project's notes contain a claim that is wrong, append a ## CORRECTIONS section to that file (live notes and archive copy) stating the false claim, why it is wrong, and the evidence — do not edit the original text. History stays intact; future readers see the refutation next to the claim.

Write mechanics

  • ~/.sisyphus/archive/ is whitelisted for your write/edit tools (read before edit, as usual).
  • Another project's LIVE notes are outside your write/edit scope — append corrections there via bash: cat >> <path>/notes/experiments.md << 'EOF' .... Append-only; never rewrite or delete in another project's tree.

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 Muuuun/luxas (1,169 stars, last pushed yesterday), licensed MIT. It adds 24 tokens to every session and 545 once invoked, about $0.0001 per session on Opus 5.5. 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.
