This is a collection of small add-ons, called skills, for AI coding agents like Claude Code and Codex. A coding agent is an AI assistant that can read and change code on your behalf. The idea here is to give teams optional pieces they can install and adapt, rather than a single heavy process framework, so the AI keeps room to think where judgment matters. The README lists several skills. Two of them, efficient-fable and efficient-frontier, deal with cost. They keep an expensive, capable AI model focused on planning, tradeoffs, and final review, while cheaper agents do the token-heavy grunt work like reading every file or reducing logs. The point is to avoid wasting money on the pricey model for routine reading. Another skill, stay-within-limits, checks how much of your usage allowance you have left over a five-hour and weekly window, and pauses new work at 95 percent so a long session does not run out mid-task. Two more, visual-plan and visual-recap, turn plain text plans or code-change summaries into richer interactive views with diagrams, file maps, and annotated diffs, so a human can review and approve before or after code changes. A final skill, quick-recap, adds a simple convention where every response ends with a green, yellow, or red status signal showing whether the work is done, waiting on a step, or blocked. Installation is done through a command-line installer run with npx, which walks you through which skills to add, whether you use Codex or Claude Code, and whether to install at the user or project level. It can also add instruction blocks for the agent and an optional GitHub Action. The README notes an alternative installer exists for plain copying but it skips those extra instruction blocks.
