Ponytail provides a structured approach to reducing system complexity. It helps technical leads and architects identify unnecessary abstractions and replace over-engineered patterns with standard library features or native implementations.
The skill set transforms scattered shortcut comments into a centralized debt ledger, ensuring that temporary deferrals are tracked and resolved rather than forgotten in the codebase.
Follow the documented setup, then try a first task.
Installs: Complete Ponytail plugin bundle · Claude Code, Claude Code Desktop
In a Claude Code agent session, send this marketplace command as its own prompt.
/plugin marketplace add DietrichGebert/ponytail
In a second, separate Claude Code prompt, install the Ponytail plugin.
/plugin install ponytail@ponytail
In Claude Code Desktop's Code tab, the same two commands can be entered into the prompt box. Alternatively, use the + button, choose Plugins → Add plugin, browse configured marketplaces, and manage marketplaces from Customize in the sidebar.
Installs: Complete Ponytail plugin bundle · Codex, Codex desktop app
Run this complete command block in a terminal to add the marketplace and install the Ponytail plugin.
codex plugin marketplace add DietrichGebert/ponytail codex plugin add ponytail@ponytail
Start Codex, open /hooks in the Codex agent session, review and trust the two lifecycle hooks, then start a new thread.
For the Codex desktop app, restart the app after installation so it detects the same plugin.
Installs: Complete Ponytail plugin bundle · GitHub Copilot CLI
Run this complete command block in a terminal to add the marketplace and install the Ponytail plugin.
copilot plugin marketplace add DietrichGebert/ponytail copilot plugin install ponytail@ponytail
Uses ponytail-review
Use ponytail-review to inspect the current diff for unnecessary complexity. List only concrete opportunities to delete code, use the standard library or a native feature, remove speculative abstractions, or express the same logic more briefly. Include locations and replacements, estimate the net lines removable, and do not apply any fixes.
Uses ponytail-debt
Use ponytail-debt to scan this repository for ponytail: shortcut comments. Return a read-only ledger grouped by file, including each marker's line, stated ceiling, upgrade trigger, and a no-trigger tag where the comment lacks an upgrade path. Do not write the ledger to a file.
Uses ponytail-audit
Use ponytail-audit to scan this repository for over-engineering. Return a ranked, read-only list of the largest opportunities to delete, simplify, or replace code with standard-library or native features, including paths and an estimated net reduction. Do not apply changes, and leave correctness, security, and performance review out of scope.
