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 | $0.00023 | $0.00132 |
| Opus 5.5 | $0.00009 | $0.00053 |
| Sonnet 5.5 | $0.00005 | $0.00026 |
| Haiku 4.5 | $0.00002 | $0.00013 |
Grade A, and why
RSpec Test Framework 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 1mo 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
RSpec Test Framework
Purpose
Provide RSpec test execution and generation for Ruby projects.
Usage
ruby generate-test.rb --source=lib/calculator.rb --output=spec/calculator_spec.rb --description="Division by zero"
ruby run-test.rb --file=spec/calculator_spec.rb
Output Format
JSON with success, passed, failed, total, and failures array.
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.

RSpec Test Framework is a skill published in the GitHub repository FortiumPartners/ensemble (12 stars, last pushed 7d ago), licensed MIT. It adds 23 tokens to every session and 132 once invoked, about $0.0001 per session on Opus 5.5. 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.
