Skill Refresh

Refresh Skill (Direct Execution)

Direct execution skill for managing Claude Code resources. Performs two operations:

1. Process cleanup: Identify and terminate orphaned Claude Code processes
2. Directory cleanup: Clean up accumulated files in ~/.claude/

This skill executes inline without spawning a subagent.

Execution

Step 1: Parse Arguments

Extract flags from command input:

• --dry-run: Preview mode
• --force: Skip confirmation, use 8-hour default

# Parse from command input
dry_run=false
force=false
if [[ "$*" == *"--dry-run"* ]]; then
  dry_run=true
fi
if [[ "$*" == *"--force"* ]]; then
  force=true
fi

Step 2: Run Process Cleanup

Execute process cleanup script:

.claude/scripts/claude-refresh.sh $( [ "$force" = true ] && echo "--force" )

Store process cleanup output for display.

Step 3: Clean Orphaned Postflight Markers

Clean any orphaned postflight coordination files from the specs directory. These files should normally be cleaned up by skills after postflight completes, but may be left behind if a process is interrupted.

echo ""
echo "=== Cleaning Orphaned Postflight Markers ==="
echo ""

# Find orphaned postflight markers (older than 1 hour)
orphaned_pending=$(find specs -maxdepth 3 -name ".postflight-pending" -mmin +60 -type f 2>/dev/null)
orphaned_guard=$(find specs -maxdepth 3 -name ".postflight-loop-guard" -mmin +60 -type f 2>/dev/null)

# Also check for legacy global markers
legacy_pending=""
legacy_guard=""
if [ -f "specs/.postflight-pending" ]; then
    legacy_pending="specs/.postflight-pending"
fi
if [ -f "specs/.postflight-loop-guard" ]; then
    legacy_guard="specs/.postflight-loop-guard"
fi

if [ -n "$orphaned_pending" ] || [ -n "$orphaned_guard" ] || [ -n "$legacy_pending" ] || [ -n "$legacy_guard" ]; then
    if [ "$dry_run" = true ]; then
        echo "Would delete the following orphaned markers:"
        [ -n "$orphaned_pending" ] && echo "$orphaned_pending"
        [ -n "$orphaned_guard" ] && echo "$orphaned_guard"
        [ -n "$legacy_pending" ] && echo "$legacy_pending"
        [ -n "$legacy_guard" ] && echo "$legacy_guard"
    else
        # Delete orphaned task-scoped markers
        find specs -maxdepth 3 -name ".postflight-pending" -mmin +60 -delete 2>/dev/null
        find specs -maxdepth 3 -name ".postflight-loop-guard" -mmin +60 -delete 2>/dev/null

        # Delete legacy global markers
        rm -f specs/.postflight-pending 2>/dev/null
        rm -f specs/.postflight-loop-guard 2>/dev/null

        echo "Cleaned orphaned postflight markers."
    fi
else
    echo "No orphaned postflight markers found."
fi

Step 4: Run Directory Survey

Show current directory status without cleaning yet:

.claude/scripts/claude-cleanup.sh

This displays:

• Current ~/.claude/ directory size
• Breakdown by directory
• Space that can be reclaimed

Step 5: Execute Based on Mode

Dry-Run Mode

If --dry-run is set:

echo ""
echo "=== DRY RUN MODE ==="
echo "Showing 8-hour cleanup preview..."
echo ""
.claude/scripts/claude-cleanup.sh --dry-run --age 8

Exit after showing preview.

Force Mode

If --force is set:

echo ""
echo "=== EXECUTING CLEANUP (8-hour default) ==="
echo ""
.claude/scripts/claude-cleanup.sh --force --age 8

Show results and exit.

Interactive Mode (Default)

If neither flag is set:

1. Check if cleanup candidates exist (claude-cleanup.sh exits with code 1 if candidates found)

2. If no candidates, display message and exit:

No cleanup candidates found within default thresholds.
All files are either protected or recently modified.

3. If candidates exist, prompt user for age selection:

{
  "question": "Select cleanup age threshold:",
  "header": "Age Threshold",
  "multiSelect": false,
  "options": [
    {
      "label": "8 hours (default)",
      "description": "Remove files older than 8 hours - aggressive cleanup"
    },
    {
      "label": "2 days",
      "description": "Remove files older than 2 days - conservative cleanup"
    },
    {
      "label": "Clean slate",
      "description": "Remove everything except safety margin (1 hour)"
    }
  ]
}

4. Map user selection to age parameter:

   • "8 hours (default)" → --age 8
   • "2 days" → --age 48
   • "Clean slate" → --age 0

5. Execute cleanup with selected age:

case "$selection" in
  "8 hours (default)")
    .claude/scripts/claude-cleanup.sh --force --age 8
    ;;
  "2 days")
    .claude/scripts/claude-cleanup.sh --force --age 48
    ;;
  "Clean slate")
    .claude/scripts/claude-cleanup.sh --force --age 0
    ;;
esac

6. Display cleanup results

Example Execution Flows

# User runs: /refresh

# Output:
Claude Code Refresh
===================

No orphaned processes found.
All 3 Claude processes are active sessions.

# Prompt appears:
[Age Threshold]
Select cleanup age threshold:
  1. 8 hours (default) - Remove files older than 8 hours
  2. 2 days - Remove files older than 2 days
  3. Clean slate - Remove everything except safety margin

# User selects option 1

# Cleanup executes:
Cleanup Complete
================
Deleted: 5577 files
Failed:  0 files

Dry-Run Flow

# User runs: /refresh --dry-run

# Shows survey, then:
=== DRY RUN MODE ===
Showing 8-hour cleanup preview...

Would delete: 5577 files
Would reclaim: 6.7 GB

Dry Run Summary
===============
No changes made.

Force Flow

# User runs: /refresh --force

# Shows survey, then immediately:
=== EXECUTING CLEANUP (8-hour default) ===

Cleanup Complete
================
Deleted: 5577 files
Space reclaimed: 6.7 GB

Safety Measures

Protected Files (Never Deleted)

• sessions-index.json (in each project directory)
• settings.json
• .credentials.json
• history.jsonl

Safety Margin

Files modified within the last hour are never deleted, regardless of age threshold.

Process Safety

• Only targets orphaned processes (TTY = "?")
• Never kills active sessions
• Excludes current process tree

Error Handling

Scripts Not Found

If scripts don't exist:

Error: Cleanup scripts not found at .claude/scripts/
Please ensure claude-refresh.sh and claude-cleanup.sh are installed.

Permission Denied

If kill/delete fails due to permissions:

Warning: Some operations failed due to insufficient permissions.
Failed files: 5
Successfully deleted: 5572 files

No ~/.claude/ Directory

If directory doesn't exist:

Error: ~/.claude/ directory not found.
Nothing to clean up.
