memory-merger is a single-file skill in the github/awesome-copilot collection. You run /memory-merger >domain-name [scope], and it reads the memory file {domain}-memory.instructions.md and the matching {domain}.instructions.md. It proposes which memories to merge, waits for your "go", then rewrites the instruction file and removes the merged sections from the memory file.

Its folders are VS Code ones. Global scope is vscode-userdata:/User/prompts/ and workspace scope is .github/instructions/ in the project. SKILL.md does not mention Claude Code or Codex. The skill bundles no scripts, but it edits two files on disk.

Good for

VS Code Copilot users who keep per-topic memory and instruction files
Developers whose memory files have grown long and repetitive
Teams that keep shared project instructions under .github/instructions/
Anyone who wants to review the proposed memories and skip some before anything is merged

What it includes

Starts a merge for one domain, global by default
The domain is required, for example >clojure or >git-workflow. The scope is global, user, workspace or ws, and defaults to global.
Try: “/memory-merger >git-workflow ws”
/memory-merger >domain [scope]
Finds the memory file and the instruction file
Works out both paths from the domain and scope. If the memory file is not found, Claude globs the folder for a close match and asks you if unsure.
Files · 1. Parse input and read files
Lists each memory with its content and where it fits, then waits
Shows a Proposed Memories for Merger list and asks you to approve all with "go" or name the ones to skip. It stops until you answer.
2. Analyze and propose
Zero knowledge loss, minimal redundancy, maximum scannability
Sets the three criteria that the merged instructions are judged against.
3. Define the quality bar
Drafts the merged text and refines it before touching any file
Drafts, checks against the quality bar and refines until it meets the criteria. Files are not updated in this step.
4. Merge and iterate
Writes the instruction file and removes merged sections from the memory file
Creates or updates the instruction file, merging applyTo patterns from both files, then removes the merged sections from the memory file.
Delete · 5. Update files

Low risk

The skill rewrites one instruction file and removes merged text from the memory file, after you approve. Keep both files in git or back them up first.

Watch out for

It removes text from your memory file
After the merge it deletes the merged sections from the memory file. Commit or copy both files first. github.com
Global scope affects every VS Code project
Global is the default scope. Use workspace or ws when you only want to change one project. github.com

Questions

What does the memory-merger skill do?

It moves approved lessons from a domain memory file into the matching instruction file, then removes them from the memory file.

How do I install memory-merger in Claude Code, the Claude app or Codex?

Use the install box at the top of this page. The skill is one SKILL.md file. Its paths are VS Code folders, and SKILL.md does not mention Claude Code, the Claude app or Codex.

Does it change my files without asking?

It stops after proposing the memories and waits for your approval. After you approve it updates the instruction file and removes the merged sections from the memory file.

Which files does it touch?

{domain}-memory.instructions.md and {domain}.instructions.md, in either the VS Code user prompts folder (global) or .github/instructions/ in your workspace.

Is it safe?

It edits and removes text in two instruction files, so keep them in git or back them up first. The awesome-copilot README says its contents come from third-party developers and asks you to inspect them before installing.

Does it need an API key?

SKILL.md names no API key and bundles no scripts.
