feat: add ponytail-audit skill (#20)

* Add ponytail-audit skill Whole-codebase audit for over-engineering. Scans a repository and produces a ranked report of things to delete, simplify, or replace with stdlib/native equivalents. * Drop counting-by-number heuristics: remove Phase 5 (structural audit) and TODO-age heuristic per review * feat: slim ponytail-audit and add cross-platform parity Rewrite the ponytail-audit skill to ponytail-review's lean shape (35 lines, was 111): same five tags, repo-wide scope, ranked output. Drop the prescriptive phase walkthrough, sampling rules, report template, and the license frontmatter that no other skill carries. Add the adapters the skill was missing so it ships on every supported platform the way ponytail-review does: - commands/ponytail-audit.toml - .opencode/command/ponytail-audit.md - pi-extension registerCommand (+ test) - agent-portability and README entries Co-authored-by: Alexander Brandt <github@a13x.de> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Emeriko <dietrich.gebert@gmail.com> Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

+name: ponytail-audit
+description: >
+  Whole-repo audit for over-engineering. Like ponytail-review, but scans the
+  entire codebase instead of a diff: a ranked list of what to delete, simplify,
+  or replace with stdlib/native equivalents. Use when the user says "audit this
+  codebase", "audit for over-engineering", "what can I delete from this repo",
+  "find bloat", "ponytail-audit", or "/ponytail-audit". One-shot report, does
+  not apply fixes.
+---
+
+ponytail-review, repo-wide. Scan the whole tree instead of a diff. Rank
+findings biggest cut first.
+
+## Tags
+
+Same as ponytail-review:
+
+- `delete:` dead code, unused flexibility, speculative feature. Replacement: nothing.
+- `stdlib:` hand-rolled thing the standard library ships. Name the function.
+- `native:` dependency or code doing what the platform already does. Name the feature.
+- `yagni:` abstraction with one implementation, config nobody sets, layer with one caller.
+- `shrink:` same logic, fewer lines. Show the shorter form.
+
+## Hunt
+
+Deps the stdlib or platform already ships, single-implementation interfaces,
+factories with one product, wrappers that only delegate, files exporting one
+thing, dead flags and config, hand-rolled stdlib.
+
+## Output
+
+One line per finding, ranked: `<tag> <what to cut>. <replacement>. [path]`.
+End with `net: -<N> lines, -<M> deps possible.` Nothing to cut: `Lean already. Ship.`
+
+## Boundaries
+
+Complexity only, correctness bugs, security holes, and performance go to a
+normal review pass. Lists findings, applies nothing. One-shot.
+"stop ponytail-audit" or "normal mode" to revert.
