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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00013 | $0.01116 |
| Opus 5 | $0.00006 | $0.00558 |
| Sonnet 5 | $0.00003 | $0.00223 |
| Haiku 4.5 | $0.00001 | $0.00112 |
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 11d 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.

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
ghCLI 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.
