wire-memory-write

A rule for saving selected project decisions, corrections, and recurring conventions to Wire Memory. It also defines information that must not be stored, such as secrets and personal data.

In plain words
What is it for?
Use it after decisions, corrections, or patterns are established, and when a session ends with useful project context to retain.
Why use it?
It preserves useful context for later sessions while reducing the risk of recording sensitive or duplicated information.

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-write 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 — Write

Check ~/.wire-memory/context.md for connection status. If the file exists and shows "Connected", Wire memory is active. Use the User and Project values from that file in all writes.

When to Write

Log silently as moments happen — don't announce it:

  • Decision made — user picks an approach or you evaluate trade-offs
  • Correction received — user corrects your approach (highest value)
  • Pattern established — a convention is set or repeated
  • Session ending — brief summary of what was done and what's next

Use wire_write via MCP with structured JSON. Always include type, project, user, scope.

Scope: "project" for project-specific context (default), "global" for cross-project preferences.

Before Writing

Search first for existing entries on the same topic. If outdated, delete with wire_delete then write the replacement.

Do NOT Log

Secrets, credentials, PII, stack traces, verbatim code, or things already in git history.

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-write is a cursor rule published in the GitHub repository usewire/wire-memory (10 stars, last pushed 3mo ago), licensed MIT. It adds 246 tokens to every session, about $0.0012 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.
