memory

memory is a skill for Claude Code, Codex from sharpninja/McpServer. It costs 23 tokens per session (302 once invoked), scanned A, a copy of memory, Apache-2.0.

A durable memory layer for a GitHub Copilot coding agent. It can save, find, organize, promote, and restore information across conversations.

In plain words
What is it for?
Use it to remember decisions, preferences, procedures, facts, or entities; recall related guidance; maintain stored memories; or restore an earlier version.
Why use it?
It prevents useful project context from being lost between sessions and keeps the agent's local cache from being treated as the source of truth.

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

memory 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 19d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (tests/MemorySkill.Tests.ps1), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Origin

This is a copy

86% identical to memory — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

MCP Memory (copilot)

Use the Copilot plugin memory surface. Do not invent memories. Prefer MCP tools over local files.

Injection

At a request boundary, render required memories exactly as:

REQUIRED MEMORIES - MEMORY-REQ-001: Raw memory text.

If no required memories are visible:

REQUIRED MEMORIES - None.

Preserve raw memory text. Do not summarize, paraphrase, or add secrets.

Fallback

If the MCP server is unavailable, keep a local failsafe for mutating tools and replay after the server acknowledges the write. Agent-local memory stores are caches only.

Tools

  • memory_remember when a fact, decision, preference, procedure, or entity should persist
  • memory_recall when you need ranked guidance by meaning
  • memory_explore when you need neighborhood context from a seed
  • memory_consolidate when the operator asks for sleep/merge maintenance
  • memory_promote when the operator explicitly wants a session-log or context source remembered
  • memory_revert when current content is wrong and a snapshot should be restored

Compat CRUD remains: memory_add, memory_list, memory_update, memory_remove.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
