ai-stack: Skill for Claude Code

.agent/skills/using-superpowers/SKILL.md

using-superpowers is a skill for Claude Code, Codex from jeetkhinde/ai-stack. It costs 31 tokens per session (1,083 once invoked), scanned A, a copy of using-superpowers, MIT.

A workflow guide for checking whether a reusable skill applies before answering or taking action. It explains how to load that skill from the project files.

In plain words
What is it for?
Use it at the start of conversations to find and load applicable skills, including before asking clarifying questions.
Why use it?
It prevents relevant instructions from being missed and makes the agent follow the required process before responding.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

This is jeetkhinde/ai-stack's own configuration. It tells Claude Code and Codex how to work on ai-stack itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-stack configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

using-superpowers scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 14d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

77% identical to using-superpowers — 38 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

IF A SKILL APPLIES TO YOUR TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.

This is not negotiable. This is not optional. You cannot rationalize your way out of this.

How to Access Skills

In Antigravity: Use view_file to load a skill from .agent/skills/<skill-name>/SKILL.md (or ~/.gemini/skills/<skill-name>/SKILL.md when needed). When you load a skill, follow it directly.

In other environments: Check your platform's documentation for how skills are loaded.

Using Skills

The Rule

Invoke relevant or requested skills BEFORE any response or action. Even a 1% chance a skill might apply means that you should invoke the skill to check. If an invoked skill turns out to be wrong for the situation, you don't need to use it.

digraph skill_flow {
    "User message received" [shape=doublecircle];
    "About to EnterPlanMode?" [shape=doublecircle];
    "Already brainstormed?" [shape=diamond];
    "Invoke brainstorming skill" [shape=box];
    "Might any skill apply?" [shape=diamond];
    "Load skill via view_file" [shape=box];
    "Announce: 'Using [skill] to [purpose]'" [shape=box];

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
