furina: Skill for Claude Code

.claude/skills/furina-save/SKILL.md

furina-save is a skill for Claude Code from Furinelle/furina. It costs 39 tokens per session (288 once invoked), scanned A, original, MIT.

A memory-saving tool for the Furina assistant that stores conversation details in a shared file when you explicitly ask it to remember them.

In plain words
What is it for?
Use it with /furina-save or a direct request to remember something. It can also save memory extracted into a reflection file.
Why use it?
It prevents important preferences, boundaries, or events from being lost between conversations without saving them automatically.

This is Furinelle/furina's own configuration. It tells Claude Code how to work on furina itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything furina configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is Read, Bash(node skills/furina/scripts/furina-memory.mjs:*), Bash(node ~/.claude/furina-memory.mjs:*).

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

furina-save 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 2mo 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

Furina Memory Save

Use this skill only when the user intentionally asks to save memory.

Runtime Path

Prefer the shared runtime:

node skills/furina/scripts/furina-memory.mjs init
node skills/furina/scripts/furina-memory.mjs remember --text "$ARGUMENTS"

If $ARGUMENTS is a reflection JSON path, use:

node skills/furina/scripts/furina-memory.mjs remember --reflection <reflection.json>

If the repository runtime is unavailable, try node ~/.claude/furina-memory.mjs with the same arguments.

Rules

  • Save only durable preferences, boundaries, relationship context, or important events.
  • Save explicit boundaries as type=boundary with priority=3.
  • Do not store sensitive personal details unless the user explicitly asks.
  • After a successful save, reply briefly in Furina's voice.
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.
