DietrichGebertandClaude Opus 4.8 ce153bc95f chore: bump version to 4.6.0 (#72)
Bumps all four plugin manifests to 4.6.0 so /ponytail-help reaches the release-install hosts (Gemini CLI, Copilot CLI marketplace).

YIZIHN 084f10fb48 fix: ship the missing /ponytail-help command on Claude Code and OpenCode (#62)
Ships the previously-missing /ponytail-help adapter files (commands/ponytail-help.toml, .opencode/command/ponytail-help.md) and adds tests/commands.test.js, a parity guard asserting every pi-registered command has both adapter files. Thanks @hooni0918.

DietrichGebertandClaude Opus 4.8 2e6a93765a fix(benchmarks): count unfenced code, ASCII-safe output, refresh llama3.2 results (#67)
Fixes the local benchmark LOC counter (counted only fenced code, scored bare output 0), makes summary output ASCII-safe (a Unicode arrow crashed the script on Windows cp1252), gitignores generated artifacts, and refreshes the llama3.2 writeup with n=5 data showing the LOC effect is within the noise floor. Follow-up to #63. Verified live.

description: Quick reference for ponytail levels, skills, and commands
---
Show the ponytail quick reference. One shot, change nothing: do not switch mode, write flag files, or persist anything. Levels: /ponytail lite (build what's asked, name the lazier alternative in one line), /ponytail (full, the default ladder: YAGNI then stdlib then native then one line then minimum), /ponytail ultra (deletion before addition, challenges the requirement before building). Commands: /ponytail-review (over-engineering review of the current changes), /ponytail-audit (whole-repo over-engineering audit), /ponytail-debt (harvest ponytail: comments into a tracked ledger), /ponytail-help (this card). Deactivate with 'stop ponytail', 'normal mode', or /ponytail off; resume anytime with /ponytail. Default mode is full; change it with the PONYTAIL_DEFAULT_MODE environment variable (off|lite|full|ultra) or a config file at ~/.config/ponytail/config.json (Windows: %APPDATA%\ponytail\config.json) with {"defaultMode": "lite"}. Resolution order: env var, then config file, then full.

No API key or promptfoo required. Runs against any model served by Ollama:
```bash
ollama pull llama3.2 # or any other model
python benchmarks/benchmark-local.py --model llama3.2 --repeat 3
```
See `benchmarks/results/2026-06-15-llama3.2-local.md` for what to expect: the skill works
well on instruction-following models (Claude-class) but transfers poorly to small local
models where the multi-step decision ladder isn't reliably followed.
Tasks: email validator, JS debounce, CSV sum, React countdown, FastAPI rate-limit (see `promptfooconfig.yaml`). Single-shot completions, default temperature.

# Local model benchmark: llama3.2 via Ollama — 2026-06-15
Same 5 tasks as the Claude benchmark, same three arms (baseline / caveman / ponytail),
run against a local **llama3.2:latest** (3.2B, Q4_K_M) via Ollama on a Windows 11 machine.
Tooling: `benchmarks/benchmark-local.py` (no promptfoo needed).
> **Updated 2026-06-15:** the LOC counter now counts bare, unfenced code. It
> previously counted only fenced code blocks and scored everything else as 0,
> which silently deflated any arm whose output happened to skip the fences (small
> models do this often). Numbers below use the corrected counter at n=5 median.
> Absolute times reflect this machine (GPU-accelerated); compare arms within a
> run, not against an earlier CPU-bound machine.
## Results (n=5, median)
**Code LOC**
| arm | email | debounce | csv-sum | countdown | rate-limit | **TOTAL** |
|---|--:|--:|--:|--:|--:|--:|
| baseline | 16 | 18 | 22 | 37 | 16 | **109** |
| caveman | 16 | 21 | 18 | 46 | 32 | **133** |
| ponytail | 17 | 22 | 18 | 52 | 28 | **137** |
**Time (seconds)**
| arm | email | debounce | csv-sum | countdown | rate-limit | **TOTAL** |
|---|--:|--:|--:|--:|--:|--:|
| baseline | 3.1 | 3.7 | 3.6 | 4.2 | 4.8 | **19.4** |
| caveman | 4.1 | 4.2 | 3.6 | 4.4 | 4.8 | **21.1** |
| ponytail | 4.1 | 4.2 | 3.8 | 4.8 | 4.9 | **21.8** |
## Key findings
**On llama3.2 the LOC effect is inside the noise floor.** At temperature 0.7 the
per-run totals swing hard: across the five runs, ponytail landed anywhere from
17% *below* baseline to 50% *above* it. The n=5 median came out +26%; a separate
n=3 median came out 17%. The aggregate itself flips sign depending on the
sample, and the countdown task alone ranged 19 to 74 LOC on baseline. There is no
stable LOC reduction to report.
**Ponytail does not transfer to llama3.2.** The 80-94% LOC reduction seen on
Claude is simply absent: the signal is lost in run-to-run variance. The one
consistent effect is on time, and it goes the wrong way: ponytail is ~10-15%
*slower* than baseline (more system-prompt tokens to process), never the 3-6x
speedup seen on Claude.
**Why:** ponytail is a prompt-engineering skill calibrated on Claude models,
which are trained to follow detailed system instructions. A 3.2B quantised model
absorbs the rules only partially and adds prose justifying its choices, paying
the instruction-following cost without reliably converting it into less code.
## Reproduce
Install Ollama and pull a model, then run from the repo root:
```bash
ollama pull llama3.2
python benchmarks/benchmark-local.py --model llama3.2 --repeat 5
```
At this model size the LOC signal is noisy; raise `--repeat` (or lower the
sampling temperature in the script) before reading anything into the totals.
Optional flags:
```
--repeat N Runs per cell; median is reported (default: 1)
--ollama-url URL Ollama base URL (default: http://localhost:11434)
```
## Takeaway
The benchmark claims in the README are accurate for the models tested (Haiku,
Sonnet, Opus). For local/small models, expect the gains to shrink into the noise
until instruction-following reaches a threshold comparable to Claude Haiku or
better.
