**/ponytail-debt is a read-only Ponytail skill that recursively scans your codebase for `ponytail:` comment markers and generates a comprehensive debt ledger listing every deferred shortcut that requires future attention.**

The primary **purpose of the `/ponytail-debt` command** is to provide a lightweight audit tool that surfaces technical debt before it becomes orphaned code. When invoked in the `DietrichGebert/ponytail` repository context, `/ponytail-debt` traverses the entire repository tree to catalog intentional shortcuts left by developers, ensuring these temporary solutions don't permanently settle into the codebase.

## How the Debt Ledger Scan Works

The `/ponytail-debt` command operates as a **non-destructive reporting mechanism** that analyzes source code without modifying any files. It functions as a read-only audit that helps teams track deferred work before it rots into “later = never.”

### Pattern Matching for ponytail Markers

During execution, the command recursively greps the repository for comment patterns containing `ponytail:` markers. It recognizes both shell-style comments (`# ponytail:`) and C-style comments (`// ponytail:`), capturing the line number and description of each deferred shortcut.

### Excluding Build Artifacts and Dependencies

The scan automatically ignores standard directories that don't contain source code requiring debt tracking. Specifically, it excludes:

- `node_modules/` directories
- `.git/` version control folders
- Compiled build output directories

## Understanding the Output Format

The command emits a structured report showing exactly where each marker lives in your codebase. For every match found, it prints:

```text
<file>:<line> — <description of the shortcut>

```

After listing all individual markers, `/ponytail-debt` provides a summary line indicating the **total number of markers** and how many of them **lack an upgrade-path trigger**. If no markers exist, the command outputs a clean status message:

```text
No ponytail: debt. Clean ledger.

```

## Source Code Implementation

According to the `DietrichGebert/ponytail` source code, the `/ponytail-debt` command is implemented across three key files:

**Command Definition** — The [`commands/ponytail-debt.toml`](https://github.com/DietrichGebert/ponytail/blob/main/commands/ponytail-debt.toml) file defines the command description and prompt configuration that registers the skill with the Ponytail system.

**Skill Documentation** — The [`skills/ponytail-debt/SKILL.md`](https://github.com/DietrichGebert/ponytail/blob/main/skills/ponytail-debt/SKILL.md) file contains the full technical specification for how the ledger is built, parsed, and displayed to developers.

**Extension Registration** — The [`pi-extension/index.js`](https://github.com/DietrichGebert/ponytail/blob/main/pi-extension/index.js) file handles the actual registration of the `"ponytail-debt"` slash-command, binding the user input to the skill execution logic.

## Practical Usage Example

Invoke the command in any chat or terminal session attached to your Ponytail instance:

```bash
/ponytail-debt

```

**Sample output with existing debt markers:**

```text
src/utils.ts:23 — ponytail: replace manual loop with Array.map()
src/api/client.js:87 — ponytail: cache HTTP response
src/components/Header.tsx:45 — ponytail: extract to shared component
...
Total markers: 42, missing upgrade trigger: 5

```

**Sample output for clean repositories:**

```text
No ponytail: debt. Clean ledger.

```

## Summary

- **/ponytail-debt** scans recursively for `ponytail:` comment markers without modifying files
- It ignores `node_modules/`, `.git/`, and build output to focus on relevant source code
- Output format shows file paths, line numbers, and descriptions for each deferred shortcut
- The summary line reports total markers and missing upgrade triggers
- Three source files power the command: [`commands/ponytail-debt.toml`](https://github.com/DietrichGebert/ponytail/blob/main/commands/ponytail-debt.toml), [`skills/ponytail-debt/SKILL.md`](https://github.com/DietrichGebert/ponytail/blob/main/skills/ponytail-debt/SKILL.md), and [`pi-extension/index.js`](https://github.com/DietrichGebert/ponytail/blob/main/pi-extension/index.js)

## Frequently Asked Questions

### Does /ponytail-debt modify any source files?

No. The `/ponytail-debt` command is strictly read-only. It analyzes the repository state and generates reports without changing, deleting, or updating any files in your codebase.

### What comment formats does /ponytail-debt recognize?

The command recognizes two primary comment formats: shell-style single-line comments (`# ponytail:`) and C-style single-line comments (`// ponytail:`). The marker must include the colon immediately after "ponytail" to be detected.

### How does the command handle large repositories?

The scan recursively traverses the entire code tree while explicitly excluding `node_modules/`, `.git/`, and build output directories. This filtering ensures the command remains performant even in large Node.js or compiled projects with extensive dependency trees.

### What does "missing upgrade trigger" mean in the summary?

The summary line indicates how many of the detected `ponytail:` markers lack an associated upgrade-path trigger. These represent deferred shortcuts that don't yet have a defined plan or automated mechanism for eventual resolution, distinguishing them from tracked debt that has a clear remediation path.
