# tree-ring-memory

This skill guides agents in saving project decisions and lessons, then retrieving them when work resumes or a choice depends on prior context.

## What it does

tree-ring-memory sets out when an agent should look for earlier project notes and what kinds of lessons are worth keeping. It favours short records over conversation transcripts, covering decisions, user preferences, validated findings, and warnings. Sensitive material is blocked, redacted, or left out by default.

The instructions use the Tree Ring CLI, a project-local `.tree-ring` directory, and source sync for systems such as DOX and Revolve. DOX writes require Tree Ring CLI 0.15.11 or later; older versions can preview with `--dry-run` but cannot persist those summaries. Check the project root before setup, since initialization in the wrong directory creates memory in the wrong place.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add TerminallyLazy/Tree-Ring-Memory --skill tree-ring-memory -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add TerminallyLazy/Tree-Ring-Memory --skill tree-ring-memory -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add TerminallyLazy/Tree-Ring-Memory --skill tree-ring-memory -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install TerminallyLazy/Tree-Ring-Memory tree-ring-memory
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add TerminallyLazy/Tree-Ring-Memory --skill tree-ring-memory -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/TerminallyLazy/Tree-Ring-Memory --path skills/tree-ring-memory
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add TerminallyLazy/Tree-Ring-Memory --skill tree-ring-memory -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/TerminallyLazy/Tree-Ring-Memory/tree/HEAD/skills/tree-ring-memory/SKILL.md

## When to use it
- retrieve project decisions before changing architecture
- carry user preferences into later sessions
- record a failed approach so it is not repeated
- save a tested lesson or project warning
- preview project notes from DOX or Revolve sources

## Example prompts
- Look up earlier project decisions and warnings before changing the storage design.
- Save our data-retention decision as a short project memory with its source.
- Preview the DOX material available for import before syncing it.

# Tree Ring Memory

Use Tree Ring Memory as a lifecycle-aware memory layer, not as a transcript dump.

Tree Ring Memory preserves meaningful agent learning like tree rings:

- fresh work stays detailed
- older learning compresses into stable rings
- important warnings remain visible as scars
- durable truths become heartwood
- speculative future work stays as seeds
- sensitive data is blocked, redacted, or kept out by default

## Runtime Bootstrap And Updates

Resolve the actual project root before running Tree Ring. Never initialize a
plugin cache, downloaded package directory, home directory, or arbitrary
working directory by accident.

1. If `<project-root>/.tree-ring/bin/tree-ring` exists, prefer that binary for
   this project. Otherwise check `command -v tree-ring` and run
   `tree-ring --version`.
2. Read existing `<project-root>/.tree-ring/SKILL.md` and `CLI.md` when present.
3. If no CLI is available and the user's request already authorizes Tree Ring
   setup, install the verified current release project-locally from the project
   root. Otherwise explain the exact operation and obtain permission before the
   network download or software installation. Download the official,
   version-pinned `v0.15.0/install.sh` installer to a temporary file, verify its
   SHA-256 is
   `ef0d5eb8f09cbe2e4c3abe80ee9a98a56759c89ad4ddd103d6c68314cd653ade`,
   inspect it, and only then run:

   ```bash
   cd <project-root>
   sh <verified-installer-path> --project --init --release latest --no-animation
   ```

   Do not pipe a network response directly to a shell. The installer verifies
   the selected release archive against its published SHA-256 before placing
   the binary at `<project-root>/.tree-ring/bin/tree-ring`.

4. For an existing global CLI, initialize from the project root with
   `tree-ring --root .tree-ring init`. For a project-local CLI, use
   `.tree-ring/bin/tree-ring --root .tree-ring init`. This must place
   `memory.sqlite`, `AGENTS.md`, `SKILL.md`, and `CLI.md` under that project's
   `.tree-ring/` directory.
5. Verify the created paths and run the same binary with
   `--root .tree-ring integrations status`. Initialization creates safe local
   guidance and bridge material; it is not receipt-backed activation proof.

Check for releases without changing files:

```bash
tree-ring update --check
```
