Tether

/asciinema-tools:tether

Manage Claude Code hooks for asciinema-tools automation.

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

Arguments

Hook Definitions

PostToolUse Hook (backup-on-stop)

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Bash",
        "command": "asciinema-backup-if-active"
      }
    ]
  }
}

Execution

Skip Logic

• If action provided -> execute directly
• If hook type flags provided -> use specific hooks

Workflow

1. Status: Read current ~/.claude/settings.json 2. Action: AskUserQuestion for action type 3. Hooks: AskUserQuestion for hook selection 4. Execute: Modify settings.json 5. Verify: Confirm changes applied

Examples

# Check current hook status
/asciinema-tools:tether status

# Install auto-backup hook
/asciinema-tools:tether install --backup-on-stop

# Install without prompts
/asciinema-tools:tether install -y

# Remove all asciinema hooks
/asciinema-tools:tether uninstall

Troubleshooting

Post-Execution Reflection

After this skill completes, check before closing:

1. Did the command succeed? — If not, fix the instruction or error table that caused the failure. 2. Did parameters or output change? — If the underlying tool's interface drifted, update Usage examples and Parameters table to match. 3. Was a workaround needed? — If you had to improvise (different flags, extra steps), update this SKILL.md so the next invocation doesn't need the same workaround.

Only update if the issue is real and reproducible — not speculative.
