This is rand/mnemosyne's own configuration. It tells Claude Code how to work on mnemosyne itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mnemosyne configures →

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 B, and why

ics scanned grade B with 1 finding 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 1mo ago.

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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.

I will launch the Integrated Context Studio (ICS) for you to interactively edit a context file.

Parse arguments:

  • First positional arg: file path (optional, creates temp file if not provided)
  • --template <T>: Use template (api|architecture|bugfix|feature|refactor)
  • --readonly: Open in read-only mode (view only, no editing)
  • --panel <P>: Start with panel visible (memory|diagnostics|proposals|holes)

Examples:

/ics context.md
/ics --template api new-api-spec.md
/ics --readonly docs/architecture.md
/ics --panel memory context.md

Steps:

  1. Parse command arguments:

    • Extract file path from first positional argument
    • Extract flags: --template, --readonly, --panel
    • If no file provided: create .claude/context-temp-{timestamp}.md
  2. Prepare file:

    • If file doesn't exist and template requested: note template will be applied by ICS
    • If file doesn't exist and no template: ICS will create empty file
    • If file exists: ICS will load it
  3. Create session directory:

    mkdir -p .claude/sessions
    
  4. Build mnemosyne edit command:

    # Base command
    CMD="mnemosyne edit"
    
    # Add file path
    CMD="$CMD <file_path>"
    
    # Add options
    if [[ -n "$template" ]]; then
      CMD="$CMD --template $template"
    fi
    
    if [[ "$readonly" == "true" ]]; then
      CMD="$CMD --readonly"
    fi
    
    if [[ -n "$panel" ]]; then
      CMD="$CMD --panel $panel"
    fi
    
    # Add session context for handoff (hidden flag)
    CMD="$CMD --session-context .claude/sessions/edit-intent.json"
    
  5. Show launch message:

    🎨 Launching Integrated Context Studio...
    
    File: <file_path>
    Template: <template or "none">
    Mode: <"read-only" or "edit">
    Panel: <panel or "none">
    
    ICS will now take over your terminal.
    Edit your context with full features:
    • Vim mode (if enabled)
    • Syntax highlighting
    • Semantic analysis
    • Memory panel (Ctrl+M)
    • Diagnostics (Ctrl+D)
    • Typed holes (Ctrl+H)
    
    Save (Ctrl+S) and quit (Ctrl+Q) when done.
    
  6. Execute command (this takes over terminal):

    $CMD
    

    Note: The terminal is now controlled by ICS. Wait for user to exit.

  7. After ICS exits, read result:

    # Check if result file exists
    if [ -f .claude/sessions/edit-result.json ]; then
      # Read and parse result
      RESULT=$(cat .claude/sessions/edit-result.json)
    
      # Extract key fields with jq
      STATUS=$(echo "$RESULT" | jq -r '.status')
      CHANGES=$(echo "$RESULT" | jq -r '.changes_made')
      EXIT_REASON=$(echo "$RESULT" | jq -r '.exit_reason')
    
      # Read the edited file content
      CONTENT=$(cat <file_path>)
    else
      # No result file - user may have force-quit
      STATUS="unknown"
      CHANGES="false"
      EXIT_REASON="unknown"
      CONTENT=$(cat <file_path> 2>/dev/null || echo "")
    fi
    
  8. Display result summary:

    ✓ ICS session complete
    
    Status: <status>
    Changes made: <yes/no>
    Exit: <user_saved/user_cancelled/error>
    

    If changes_made == true and result has analysis:

    Semantic Analysis:
    • Filled <N> typed holes
    • Referenced <N> memories
    • Resolved <N> diagnostics
    • Extracted entities: <list>
    
  9. Display edited content (if not readonly):

    Here's your edited context:
    
    <CONTENT>
    
    Shall I proceed with this context?
    
  10. Cleanup:

    # Remove coordination files
    rm -f .claude/sessions/edit-intent.json
    rm -f .claude/sessions/edit-result.json
    
  11. Wait for user response:

    • If user says "yes" or "proceed": continue with the context
    • If user says "edit again" or "refine": Re-run steps 3-11
    • If user says "discard" or "cancel": Discard changes

Error handling:

  • If mnemosyne edit command fails: "Error launching ICS. Please check mnemosyne installation."
  • If user force-quits (Ctrl+C): "ICS session interrupted. File may be partially edited."
  • If timeout (5 min): "ICS session timed out. File saved to {path}."
  • If file is readonly and user tries to edit: ICS will prevent saves automatically
