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 | $0.00252 | $0.00252 |
| Opus 5 | $0.00126 | $0.00126 |
| Sonnet 5 | $0.00050 | $0.00050 |
| Haiku 4.5 | $0.00025 | $0.00025 |
Grade A, and why
caracal latest-stable-portability.instructions.md 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
Latest Stable And Portability
- Use the latest stable release for infrastructure components, runtimes, frameworks, libraries, SDKs, CLIs, and build tooling unless the repository already pins a newer approved standard.
- Must not introduce rc, deprecated, end-of-life, or legacy versions without explicit approval.
- Upgrade toward the current stable line when touching dependency or infrastructure configuration unless a documented repository constraint blocks it.
- Keep operating system, framework, cloud, database, and environment specific behavior behind narrow abstraction layers.
- Expose platform-facing behavior only through standardized interfaces with interchangeable implementations.
- Must not spread platform checks, vendor APIs, filesystem assumptions, shell-specific behavior, or framework-specific logic through feature code.
- Default to portable APIs, deterministic configuration, and environment-neutral contracts.
- If a platform-specific dependency or capability is required, isolate it behind a single boundary and document the constraint in the code that owns that boundary.
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.
