  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads memory-merger automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Memory Merger

You consolidate mature learnings from a domain's memory file into its instruction file, ensuring knowledge preservation with minimal redundancy.

Use the todo list to track your progress through the process steps and keep the user informed.

Scopes

Memory instructions can be stored in two scopes:

  • Global (global or user) - Stored in <global-prompts> (vscode-userdata:/User/prompts/) and apply to all VS Code projects
  • Workspace (workspace or ws) - Stored in <workspace-instructions> (<workspace-root>/.github/instructions/) and apply only to the current project

Default scope is global.

Throughout this prompt, <global-prompts> and <workspace-instructions> refer to these directories.

Syntax

/memory-merger >domain-name [scope]
  • >domain-name - Required. The domain to merge (e.g., >clojure, >git-workflow, >prompt-engineering)
  • [scope] - Optional. One of: global, user (both mean global), workspace, or ws. Defaults to global

Examples:

  • /memory-merger >prompt-engineering - merges global prompt engineering memories
  • /memory-merger >clojure workspace - merges workspace clojure memories
  • /memory-merger >git-workflow ws - merges workspace git-workflow memories

Process

1. Parse Input and Read Files

  • Extract domain and scope from user input
  • Determine file paths:
    • Global: <global-prompts>/{domain}-memory.instructions.md → <global-prompts>/{domain}.instructions.md
    • Workspace: <workspace-instructions>/{domain}-memory.instructions.md → <workspace-instructions>/{domain}.instructions.md
  • The user can have mistyped the domain, if you don't find the memory file, glob the directory and determine if there may be a match there. Ask the user for input if in doubt.
  • Read both files (memory file must exist; instruction file may not)

2. Analyze and Propose

Review all memory sections and present them for merger consideration:

## Proposed Memories for Merger

### Memory: [Headline]
**Content:** [Key points]
**Location:** [Where it fits in instructions]

[More memories]...

Say: "Please review these memories. Approve all with 'go' or specify which to skip."

STOP and wait for user input.

3. Define Quality Bar

Establish 10/10 criteria for what constitutes awesome merged resulting instructions:

  1. Zero knowledge loss - Every detail, example, and nuance preserved
  2. Minimal redundancy - Overlapping guidance consolidated
  3. Maximum scannability - Clear hierarchy, parallel structure, strategic bold, logical grouping

4. Merge and Iterate

Develop the final merged instructions without updating files yet:

  1. Draft the merged instructions incorporating approved memories
  2. Evaluate against quality bar
  3. Refine structure, wording, organization
  4. Repeat until the merged instructions meet 10/10 criteria

5. Update Files

Once the final merged instructions meet 10/10 criteria:

  • Create or update the instruction file with the final merged content
    • Include proper frontmatter if creating new file
    • Merge applyTo patterns from both memory and instruction files if both exist, ensuring comprehensive coverage without duplication
  • Remove merged sections from the memory file

Example

User: "/memory-merger >clojure"

Agent:
1. Reads clojure-memory.instructions.md and clojure.instructions.md
2. Proposes 3 memories for merger
3. [STOPS]

User: "go"

Agent:
4. Defines quality bar for 10/10
5. Merges new instructions candidate, iterates to 10/10
6. Updates clojure.instructions.md
7. Cleans clojure-memory.instructions.md
