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 | $0.00026 | $0.02643 |
| Opus 5 | $0.00013 | $0.01321 |
| Sonnet 5 | $0.00005 | $0.00529 |
| Haiku 4.5 | $0.00003 | $0.00264 |
Grade C, and why
rb:deploy scanned grade C with 2 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 2d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Solid Trifecta
Rails 8's "Solid Trifecta" replaces Redis for most apps:
Solid Queue
Database-backed job queue (replaces Sidekiq for many):
# Gemfile
gem 'solid_queue'
# config/application.rb
config.active_job.queue_adapter = :solid_queue
# config/recurring.yml (recurring jobs)
production:
periodic_cleanup:
class: CleanupJob
schedule: every day at 3am
Solid Cache
Database-backed caching (replaces Redis/Memcached):
# Gemfile
gem 'solid_cache'
# config/cache.yml
production:
database: cache
store_options:
max_entries: 10000000
max_size: 256.megabytes
Solid Cable
Database-backed Action Cable (replaces Redis for websockets):
# Gemfile
gem 'solid_cable'
# config/cable.yml
production:
adapter: solid_cable
polling_interval: 0.1.seconds
keep_messages_around_for: 1.day
What ships with it
3 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.

rb:deploy is a skill published in the GitHub repository slbug/claude-ruby-grape-rails (7 stars, last pushed 2d ago), licensed MIT. It adds 26 tokens to every session and 2,643 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
