A ledger of deferred shortcuts (ponytail markers) grouped by file, with ceiling, upgrade path, and rot-risk flags.
About
Ponytail-debt is a grep-based scanner that harvests deliberate technical debt markers (ponytail: comments) from a repository and consolidates them into a single ledger. Developers use it to prevent shortcuts from silently becoming permanent by making deferrals visible and trackable. The tool scans for comment patterns like `// ponytail: ceiling, upgrade-path`, groups results by file with line numbers, and flags entries lacking upgrade triggers as rot risks. Output is a one-shot report or optionally persisted to a markdown ledger file. --- name: ponytail-debt description: "Harvest every ponytail: shortcut comment into one debt ledger, so deferrals get tracked instead of forgotten. One-shot report." homepage: https://github.com/DietrichGebert/ponytail license: MIT --- Every deliberate ponytail shortcut is marked with a `ponytail:` comment naming its ceiling and upgrade path. This collects them into one ledger so a deferral can't quietly become permanent. ## Scan Grep the repo for comment markers, skipping `node_modules`, `.git`, and build output: `grep -rnE '(#|//) ?ponytail:' .` (add other comment prefixes if your stack uses them) Each hit is one ledger row.
- Grep-based scanner that finds ponytail: comment markers across the entire repo
- Groups findings by file with line number, ceiling, and upgrade path extracted from comments
- Flags deferred shortcuts with no upgrade trigger as no-trigger rot risks
- Reads-only by default; optionally writes ledger to PONYTAIL-DEBT.md on request
- Skips node_modules, .git, and build output automatically

What it does
Scan codebase for deferred shortcuts marked with ponytail comments and generate a debt ledger report.
Who is it for?
Teams using shortcut-deferral conventions who want to audit and track deferred work across the codebase.
Skip if: Projects without a ponytail comment convention or those seeking automated refactoring tools.
When should I use this skill?
Conducting technical debt audits, reviewing deferred shortcuts, or preparing for debt paydown cycles.
What you get
Developers gain visibility into all deferred shortcuts and can identify which ones lack upgrade triggers, preventing silent debt accumulation.
- Technical debt ledger report
By the numbers
- Outputs N markers and M with no trigger
- Skips node_modules, .git, and build output
Files
Every deliberate ponytail shortcut is marked with a ponytail: comment naming its ceiling and upgrade path. This collects them into one ledger so a deferral can't quietly become permanent.
Scan
Grep the repo for comment markers, skipping node_modules, .git, and build output:
grep -rnE '(#|//) ?ponytail:' . (add other comment prefixes if your stack uses them)
Each hit is one ledger row. The comment prefix keeps prose that merely mentions the convention out of the ledger.
Output
One row per marker, grouped by file:
<file>:<line>, <what was simplified>. ceiling: <the limit named>. upgrade: <the trigger to revisit>.
The convention is ponytail: <ceiling>, <upgrade path>, so pull the ceiling and the trigger straight from the comment. Want an owner per row too? add git blame -L<line>,<line>.
Flag the rot risk: any ponytail: comment that names no upgrade path or trigger gets a no-trigger tag, those are the ones that silently rot.
End with <N> markers, <M> with no trigger. Nothing found: No ponytail: debt. Clean ledger.
Boundaries
Reads and reports only, changes nothing. To persist it, ask and it writes the ledger to a file (e.g. PONYTAIL-DEBT.md). One-shot. "stop ponytail-debt" or "normal mode" to revert.

What is a ponytail shortcut?
A deliberate code simplification or deferral marked with a ponytail: comment naming its ceiling (limit) and upgrade path (when to revisit).
What makes a ponytail rot?
A ponytail marker with no upgrade path or trigger gets flagged as no-trigger; these silently become permanent debt without revisit criteria.
Does it modify code?
No. It reads and reports only. On request, it can write the ledger to PONYTAIL-DEBT.md but never alters source code.
Is Ponytail Debt safe to install?
