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 | $0.00030 | $0.00513 |
| Opus 5 | $0.00015 | $0.00257 |
| Sonnet 5 | $0.00006 | $0.00103 |
| Haiku 4.5 | $0.00003 | $0.00051 |
Grade A, and why
guardrails 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.
What it actually says
Guardrails
When to Invoke
- Pre-Flight: before writing any code
- Self-Review: after writing code, before verification
Pre-Flight
- Identified applicable rules from
GEMINI.md - Searched for existing patterns (Pattern Discovery — GEMINI.md § Architectural Patterns)
- Project structure aligned (GEMINI.md § Project Structure)
- I/O boundaries identified for abstraction
- Test strategy determined (unit/integration/E2E)
- Reviewed GEMINI.md § Rule Priority for conflicts
Any item unchecked → STOP and resolve.
Post-Implementation Self-Review
Security:
- No hardcoded secrets/config
- User input validated at boundaries
- Parameterized queries (no SQL concat)
Testability:
- I/O behind interfaces
- Business logic pure (no side effects in calcs)
- Dependencies injected
Observability:
- Public ops logged (start/success/failure)
- Structured logging with correlationId
- Appropriate log levels
Error Handling:
- Explicit error paths (no empty catch)
- Errors wrapped with context
- Resources cleaned up (defer/finally)
Testing:
- Happy path covered
- ≥2 error paths covered
- Domain edge cases
- I/O adapters modified → integration tests
- UI modified → E2E tests exist/planned
Consistency:
- Follows codebase patterns (>80%)
- Naming conventions match
- File org matches GEMINI.md § Project Structure

What ships with it
1 file 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.
- 11d ago First seen · 75 lines · 30 tokens per session scan A e623a5ce348d
guardrails is a skill published in the GitHub repository irahardianto/rugged-gemini (5 stars, last pushed 4mo ago), licensed MIT. It adds 30 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.
