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 | $0.00330 | $0.00330 |
| Opus 5 | $0.00165 | $0.00165 |
| Sonnet 5 | $0.00066 | $0.00066 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
caracal product-isolation.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 10d 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
Product Isolation
- Treat
caracal/andcaracalEnterprise/as separate products with a hard architectural boundary. - Must not import, require, reference, or load source files across the
caracal/andcaracalEnterprise/roots. - Must not add workspace, package-manager, build, or generated-artifact links that make one product depend on the other.
- Must not copy, mirror, or move implementation code from one product into the other as a shortcut for reuse.
- Shared behavior must only cross the boundary through explicitly approved, license-compliant interfaces.
- If an approved interface does not already exist, stop and ask for the sanctioned interface location or contract before implementing cross-product reuse.
- Keep tests, fixtures, generated files, and documentation references isolated to the product they belong to unless an approved interface explicitly requires otherwise.
- When parallel changes are needed in both products, implement them independently on each side of the boundary.
- Enforce separate local ports for all OSS and enterprise services. Localhost ports used by
caracal/services must not be reused bycaracalEnterprise/services in code, config, Docker files, examples, or documentation. - When introducing or changing a local service port, keep the assignment explicit and non-overlapping across the workspace so local OSS and enterprise stacks can run side by side.
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.

caracal product-isolation.instructions.md is an instructions file published in the GitHub repository Garudex-Labs/caracal (206 stars, last pushed 2d ago), licensed Apache-2.0. It adds 330 tokens to every session, about $0.0016 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 2026-08-30.
