Prompt

A project memory entry contains a sensitive user email address, but the structural architectural lesson in the memory remains valuable and needs to stay visible. Should we delete the entire entry or redact it, and what flag option specifies this?

What's inside

The instructions your model reads when the skill loads.

SKILL.md290 linessingle file

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:

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

First Check

If the current project contains Tree Ring files, read them before using global assumptions:

.tree-ring/SKILL.md
.tree-ring/CLI.md

If the CLI is not installed, use the canonical project install guide: https://github.com/TerminallyLazy/Tree-Ring-Memory#install

This wrapper requires Tree Ring Memory CLI >= 0.13.0. Check before using a shared store or v0.13 policy commands:

tree-ring --version

On macOS ARM64:

brew tap TerminallyLazy/tree-ring
brew install tree-ring
