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 5.1 | $0.00033 | $0.00513 |
| Opus 5 | $0.00016 | $0.00257 |
| Sonnet 5 | $0.00007 | $0.00103 |
| Haiku 4.5 | $0.00003 | $0.00051 |
Grade A, and why
superpowers-ruby:handoff-list 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.
What it actually says
Handoff List
Overview
Display all available handoff documents, both active (unrestored) and archived (consumed). Helps you decide which handoff to resume or review.
Announce at start: "I'm using the handoff-list skill to show available handoffs."
When to Use
- When starting a session and unsure if handoffs exist
- When you want to review past handoff history
- Before using

The Process
Step 1: Scan Handoff Directories
# Active handoffs
ls docs/handoffs/*.md 2>/dev/null
# Archived handoffs
ls docs/handoffs/_archive/*.md 2>/dev/null
Step 2: Parse Frontmatter
For each file found, read the YAML frontmatter to extract: created, topic, branch, trigger, restored.
Step 3: Display Table
Present results with active (unrestored) handoffs first, then archived, sorted by date descending:
## Active Handoffs
| Date | Topic | Branch | Trigger |
|------|-------|--------|---------|
| 2026-04-14 | handoff-skill | lg/handoff | manual |
## Archived Handoffs
| Date | Topic | Branch | Trigger | Restored At |
|------|-------|--------|---------|-------------|
| 2026-04-13 | auth-refactor | fix/auth | compact | 2026-04-13T15:30:00 |
If no handoffs exist:
No handoff documents found in docs/handoffs/ or docs/handoffs/_archive/.
Use `/superpowers-ruby:handoff` to create one.
Step 4: Offer Next Action
If active handoffs exist, offer:
"Would you like to resume from one of the active handoffs? Use
/superpowers-ruby:handoff-resume."
Pairs With
- superpowers-ruby:handoff — Creates new handoff documents
- superpowers-ruby:handoff-resume — Resume from a specific handoff
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.
- 9d ago First seen · 72 lines · 33 tokens per session scan A 600e72a7a851
superpowers-ruby:handoff-list is a skill published in the GitHub repository zarpay/rails-template (9 stars, last pushed 27d ago), licensed MIT. It adds 33 tokens to every session and 513 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.
