Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/mineugene-ponytail-gain
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

# Ponytail Gain
Display this scoreboard. One-shot: do not change mode, write flag files, or
persist anything.
The figures are published benchmark medians over 5 tasks (email validator,
debounce, CSV sum, countdown timer, rate limiter) and 3 models (Haiku, Sonnet,
Opus), measured from `benchmarks/` and the README. They are not computed from
the current repository.
## Scoreboard
Render plain ASCII bars. The bar length shows the measured range; the label
carries the exact figure:
```
ponytail gain benchmark median - 5 tasks - 3 models
Lines of code no-skill #################### 100%
ponytail ##.................. 6-20% down 80-94%
Cost no-skill #################### 100%
ponytail #####............... 23-53% down 47-77%
Speed ponytail 3-6x faster
This repo: $skill:ponytail-debt (shortcuts you deferred)
$skill:ponytail-audit (what's still cuttable)
```
## Honesty boundary
Do not print a per-repository savings number. The unbuilt version was never
written, so no real baseline exists in a live repository. The only real
per-repository figure is the counted ledger from `$skill:ponytail-debt`; point
there instead.
## Exclusions
One-shot display. Edit nothing. Do not change the Ponytail runtime mode.From mineugene/pi-dev-config, MIT.
