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 | $0.00000 | $0.00244 |
| Opus 5 | $0.00000 | $0.00122 |
| Sonnet 5 | $0.00000 | $0.00049 |
| Haiku 4.5 | $0.00000 | $0.00024 |
Grade A, and why
spec-integration 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 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.
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
Integration specs
- Follow shared conventions in
spec.mdc(namedsubject,describe/context,described_class).
Use integration specs only for behavior that unit/validator specs cannot express cleanly:
- Several validators stacked on one model (especially legacy demo models with
proc_*twins) - Cross-validator interactions (metadata cache sharing, Proc options based on another attachment property, nested attributes)
- Persistence lifecycles (attach → save → purge → reload blob counts)
- Cross-cutting fail-closed timeout behavior →
spec/validators/integration/command_timeout_spec.rb(not a single-validator file)
Do not duplicate single-validator option matrices here — those belong in spec/validators/*_spec.rb via shared examples.
Prefer focused, named examples over one giant smoke file. When removing an old smoke assertion, confirm coverage exists elsewhere first.
Use describe for named units/topics (User presence, #less_than) and context for situations (when …, with …, without …).
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.

spec-integration is a cursor rule published in the GitHub repository igorkasyanchuk/active_storage_validations (1,191 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 244 tokens. 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.
