Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00040 | $0.00941 |
| Opus 5 | $0.00020 | $0.00470 |
| Sonnet 5 | $0.00008 | $0.00188 |
| Haiku 4.5 | $0.00004 | $0.00094 |
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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 102 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.
Getting Started with Skills
MANDATORY FIRST RESPONSE PROTOCOL
Before responding to ANY user message, you MUST complete this checklist:
- ☐ List available skills in your mind
- ☐ Ask yourself: "Does ANY skill match this request?"
- ☐ If yes → Use the Skill tool to read and run the skill file
- ☐ Announce which skill you're using
- ☐ Follow the skill exactly
Responding WITHOUT completing this checklist = automatic failure.
Critical Rules
-
Follow mandatory workflows. Brainstorming before coding. Check for relevant skills before ANY task.
-
Execute skills with the Skill tool
Common Rationalizations That Mean You're About To Fail
If you catch yourself thinking ANY of these thoughts, STOP. You are rationalizing. Check for and use the skill.
- "This is just a simple question" → WRONG. Questions are tasks. Check for skills.
- "I can check git/files quickly" → WRONG. Files don't have conversation context. Check for skills.
- "Let me gather information first" → WRONG. Skills tell you HOW to gather information. Check for skills.
- "This doesn't need a formal skill" → WRONG. If a skill exists for it, use it.
- "I remember this skill" → WRONG. Skills evolve. Run the current version.
- "This doesn't count as a task" → WRONG. If you're taking action, it's a task. Check for skills.
- "The skill is overkill for this" → WRONG. Skills exist because simple things become complex. Use it.
- "I'll just do this one thing first" → WRONG. Check for skills BEFORE doing anything.
Why: Skills document proven techniques that save time and prevent mistakes. Not using available skills means repeating solved problems and making known errors.
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.
- 3d ago First seen · 102 lines · 40 tokens per session scan A 8421cac4e142
using-superpowers is a skill published in the GitHub repository movebrickschi/harness-engineering-mcp (2 stars, last pushed 3mo ago), licensed MIT. It adds 40 tokens to every session and 941 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
systematic-debugging
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes.
brainstorming
You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
auto-perf-optimize
Run agent-driven VS Code performance or memory investigations. Use when asked to launch Code OSS, automate a VS Code scenario, run the Chat memory smoke runner, capture renderer heap snapshots, take workflow screenshots, compare run summaries, or drive a repeatable scenario before heap-snapshot analysis.
chat-perf
Run chat perf benchmarks and memory leak checks against the local dev build or any published VS Code version. Use when investigating chat rendering regressions, validating perf-sensitive changes to chat UI, or checking for memory leaks in the chat response pipeline.
chat-pet-sprite-creation
Use when creating or changing VS Code chat pet sprite art, sprite sheets, state animations, eye treatments, Stable/Insiders variants, or pet transitions under src/vs/workbench/contrib/chat/browser/widget/media/chatPet.
cpu-profile-analysis
Analyze V8/Chrome CPU profiles (.cpuprofile) and DevTools trace files (Trace-.json). Use when: profiling performance, investigating slow functions, comparing code paths, finding bottlenecks, analyzing timeToRequest, understanding call trees from sampling profiler data, analyzing layout/paint/rendering, investigating…
