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

Sharing 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 8d 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

100% identical to Sharing Skills — 0 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.

Sharing Skills

Overview

Contribute skills from your local branch back to the upstream repository.

Workflow: Branch → Edit/Create skill → Commit → Push → PR

When to Share

Share when:

  • Skill applies broadly (not project-specific)
  • Pattern/technique others would benefit from
  • Well-tested and documented
  • Follows skills/meta/writing-skills guidelines

Keep personal when:

  • Project-specific or organization-specific
  • Experimental or unstable
  • Contains sensitive information
  • Too narrow/niche for general use

Prerequisites

  • gh CLI installed and authenticated
  • Working directory is ~/.config/superpowers/skills/ (your local clone)
  • Skill has been tested (see skills/meta/writing-skills for TDD process)

Sharing Workflow

1. Ensure You're on Main and Synced

cd ~/.config/superpowers/skills/
git checkout main
git pull upstream main
git push origin main  # Push to your fork

2. Create Feature Branch

# Branch name: add-skillname-skill
skill_name="your-skill-name"
git checkout -b "add-${skill_name}-skill"

3. Create or Edit Skill

# Work on your skill in skills/
# Create new skill or edit existing one
# Skill should be in skills/category/skill-name/SKILL.md

4. Commit Changes

# Add and commit
git add skills/your-skill-name/
git commit -m "Add ${skill_name} skill

$(cat <<'EOF'
Brief description of what this skill does and why it's useful.

Tested with: [describe testing approach]
EOF
)"

5. Push to Your Fork

git push -u origin "add-${skill_name}-skill"

6. Create Pull Request

# Create PR to upstream using gh CLI
gh pr create \
  --repo upstream-org/upstream-repo \
  --title "Add ${skill_name} skill" \
  --body "$(cat <<'EOF'
## Summary
Brief description of the skill and what problem it solves.

## Testing
Describe how you tested this skill (pressure scenarios, baseline tests, etc.).

## Context
Any additional context about why this skill is needed and how it should be used.

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.
