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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 5.1 | $0.00017 | $0.00935 |
| Opus 5 | $0.00009 | $0.00467 |
| Sonnet 5 | $0.00003 | $0.00187 |
| Haiku 4.5 | $0.00002 | $0.00093 |
Grade A, and why
Getting Started with Skills 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 9d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Getting Started with Skills
Critical Rules
-
Use Read tool before announcing skill usage. The session-start hook does NOT read skills for you. Announcing without calling Read = lying.
-
Follow mandatory workflows. Brainstorming before coding. Check for skills before ANY task.
-
Create TodoWrite todos for checklists. Mental tracking = steps get skipped. Every time.
Mandatory Workflow: Before ANY Task
1. Check skills list at session start, or run find-skills [PATTERN] to filter.
2. If relevant skill exists, YOU MUST use it:
- Use Read tool with full path:
${SUPERPOWERS_SKILLS_ROOT}/skills/category/skill-name/SKILL.md - Read ENTIRE file, not just frontmatter
- Announce: "I've read [Skill Name] skill and I'm using it to [purpose]"
- Follow it exactly
Don't rationalize:
- "I remember this skill" - Skills evolve. Read the current version.
- "Session-start showed it to me" - That was using-skills/SKILL.md only. Read the actual skill.
- "This doesn't count as a task" - It counts. Find and read skills.
Why: Skills document proven techniques that save time and prevent mistakes. Not using available skills means repeating solved problems and making known errors.
If a skill for your task exists, you must use it or you will fail at your task.
Skills with Checklists
If a skill has a checklist, YOU MUST create TodoWrite todos for EACH item.
Don't:
- Work through checklist mentally
- Skip creating todos "to save time"
- Batch multiple items into one todo
- Mark complete without doing them
Why: Checklists without TodoWrite tracking = steps get skipped. Every time. The overhead of TodoWrite is tiny compared to the cost of missing steps.
Examples: skills/testing/test-driven-development/SKILL.md, skills/debugging/systematic-debugging/SKILL.md, skills/meta/writing-skills/SKILL.md
Announcing Skill Usage
After you've read a skill with Read tool, announce you're using it:
"I've read the [Skill Name] skill and I'm using it to [what you're doing]."
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

Getting Started with Skills is a skill published in the GitHub repository obra/superpowers-skills (746 stars, last pushed 10mo ago), licensed MIT. It adds 17 tokens to every session and 935 once invoked, about $0.0001 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 2026-08-30.
Other skills, from other repositories
hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".
book-mirror
Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's…
miniapp
Build a tiny interactive HTML playground only when someone asks to see, play with, or step through a mechanism.
eli5
Explain research, papers, or technical ideas in plain English with minimal jargon, concrete analogies, and clear takeaways. Use when the user says "ELI5 this", asks for a simple explanation of a paper or research result, wants jargon removed, or asks what something technically dense actually means.
deck-course-module
A course or workshop slide template with persistent learning goals, teaching pages, multiple-choice self-tests, and a wrap-up.
master-yinguang
A reference-based assistant for questions about Yinguang and Pure Land Buddhism, a Buddhist tradition focused on faith, ethical living, and practice connected with rebirth in the Pure Land. It can answer in Yinguang’s historical teaching style.
