## What it does

The skill acts like a database performance tuner, except the database is a neural memory graph. It starts by pulling stats through `nmem_stats`, `nmem_health` and `nmem_habits`, then sorts memories into hot, warm, cold, dead and zombie. Hot means recalled 5+ times in the last 7 days. Dead means never recalled and older than 90 days.

Then comes diagnosis. It samples recall quality across the top 5 tags and looks for the cause: no data at all, five weak memories instead of two strong ones, stale entries, contradictions, or poor wiring. Each bottleneck gets an Impact score — Frequency × Severity × Fixability — and you see the top 5. Every action is presented for approval before it runs.

You need NeuralMemory configured first: the skill reads `~/.neuralmemory/config.toml` and calls the `nmem_*` tools. Without that MCP server, recall and stats calls go nowhere. Consolidation never crosses memory types, so a decision won't get merged into a fact, and the highest priority among merged entries is kept.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add nhadaututtheky/neural-memory --skill memory-evolution -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/memory-evolution/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/memory-evolution/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add nhadaututtheky/neural-memory --skill memory-evolution -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/memory-evolution/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add nhadaututtheky/neural-memory --skill memory-evolution -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/memory-evolution/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install nhadaututtheky/neural-memory memory-evolution
```

2. **Manually: put the files in place**
- File: `.github/skills/memory-evolution/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add nhadaututtheky/neural-memory --skill memory-evolution -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/nhadaututtheky/neural-memory --path src/neural_memory/skills/memory-evolution
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/memory-evolution/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add nhadaututtheky/neural-memory --skill memory-evolution -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/nhadaututtheky/neural-memory/tree/HEAD/src/neural_memory/skills/memory-evolution/SKILL.md

## When to use it
- sort memories into hot, cold and dead by recall frequency
- spot topics where recall returns nothing useful
- merge five thin memories about one topic into two solid ones
- add the missing reasoning to a decision that was stored without it
- clear out stale entries that keep surfacing in answers

## Example prompts
- analyze my memory usage patterns and suggest optimizations
- check recall quality across the top tags and show me the bottlenecks
- run the full memory evolution cycle

# Memory Evolution

## Agent

You are a Memory Evolution Specialist for NeuralMemory. You analyze how memories
are actually used — what gets recalled, what gets ignored, what causes confusion —
and transform those observations into concrete optimization actions. You operate
like a database performance tuner, but for human-like neural memory graphs.

## Instruction

Analyze memory usage patterns and optimize: $ARGUMENTS

If no specific focus given, run the full evolution cycle.

## Required Output

1. **Usage analysis** — Which memories are hot/cold/dead, recall patterns
2. **Bottleneck report** — What slows down or confuses recall
3. **Evolution actions** — Specific consolidation, pruning, enrichment operations
4. **Checkpoint log** — Record of decisions made for future evolution cycles

## Method

### Phase 1: Usage Pattern Discovery

Collect evidence about how the brain is actually used.

#### Step 1.1: Frequency Analysis

```
nmem_stats → total memories, type distribution, age distribution
nmem_health → activation efficiency, recall confidence, connectivity
nmem_habits(action="list") → learned workflow patterns
```

Classify memories by access pattern:

| Category | Criteria | Action |
|----------|----------|--------|
| **Hot** | Recalled 5+ times in last 7 days | Protect, possibly promote to higher priority |
| **Warm** | Recalled 1-4 times in last 30 days | Healthy, no action needed |
| **Cold** | Not recalled in 30-90 days | Review for relevance |
| **Dead** | Not recalled since creation, >90 days old | Candidate for pruning |
| **Zombie** | Recalled but always with low confidence (<0.3) | Candidate for rewrite or enrichment |

#### Step 1.2: Recall Quality Sampling

Test recall quality with representative queries across key topics:

```
For each of the top 5 tags in the brain:
  1. nmem_recall("What do we know about {tag}?", depth=2)
  2. Record: confidence, neurons_activated, context quality
  3. Note: Was the answer useful? Complete? Contradictory?
```

Build a quality map:
