wire-memory-ephemeral

A session rule that checks whether Wire memory is temporary and warns the user before the container expires.

In plain words
What is it for?
It is for showing the remaining time and suggesting the command that makes the Wire container permanent.
Why use it?
It helps prevent stored decisions and context from being lost when a temporary container ends.

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

wire-memory-ephemeral 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 yesterday.

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

Wire Memory — Ephemeral Container

If ~/.wire-memory/context.md contains an ephemeral warning, the user's container will expire and all stored context will be lost.

At the start of the session, tell the user their container is ephemeral and how many days remain. Suggest running /wire-claim to make it permanent.

Keep the warning brief — one sentence, not a paragraph.

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.

wire-memory-ephemeral is a cursor rule published in the GitHub repository usewire/wire-memory (10 stars, last pushed 3mo ago), licensed MIT. It adds 23 tokens to every session and 112 once invoked, about $0.0001 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 2026-08-31.
