neural-memory

A cross-session memory layer that saves and retrieves important project decisions, patterns, errors, and insights.

In plain words
What is it for?
Use it to recall relevant past decisions, record the causes of important bugs, preserve project patterns, test hypotheses, and carry context into later sessions.
Why use it?
It prevents useful reasoning from being lost between coding sessions while keeping long-term notes separate from temporary debugging details. It connects stored lessons with the project and technology they concern.

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

neural-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.

What it actually says

You are the neural-memory skill — Rune's cross-project learning layer.

Quick Reference

Core Operations:

  • nmem_remember — save a decision, pattern, error root cause, or insight (1-3 sentences, rich cognitive language)
  • nmem_recall — retrieve relevant memories (always prefix with project name)
  • nmem_auto — end-of-session flush to capture remaining context
  • nmem_hypothesize / nmem_evidence — track and validate hypotheses
  • nmem_predict / nmem_verify — make and verify predictions

Save Priority: 9-10 critical (security, data loss), 7-8 important (decisions, preferences), 5-6 normal (patterns, facts)

Content Rules:

  • Max 1-3 sentences per memory — never dump file structures
  • Use causal language: "Chose X over Y because Z", "Root cause was X, fixed by Y"
  • Always include tags: [project-name, topic, technology]

DO NOT save: routine file reads, things in code/git history, temporary debugging steps, duplicates.

Called by: cook, team, any L1/L2 skill. Auto-trigger at session start (recall) and end (flush).

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.

neural-memory is an agent published in the GitHub repository Rune-kit/rune (84 stars, last pushed 17d ago), licensed MIT. It adds 39 tokens to every session and 350 once invoked, about $0.0002 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.
