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 | $0.00029 | $0.00278 |
| Opus 5.5 | $0.00012 | $0.00111 |
| Sonnet 5.5 | $0.00006 | $0.00056 |
| Haiku 4.5 | $0.00003 | $0.00028 |
Grade C, and why
runtime scanned grade C with 1 finding 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 18d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- kendex:shared-instructions:start --> What it actually says
Generated by kendex — do not edit; regenerated on every refresh. Intent lives in kendex.toml.
Runtime
Scope
Non-UI runtime implementation in shell, Python, TypeScript and Go within the delegated item's requirements. UI view layers and Rust implementation stay with their owners.
Discipline
- Read the project's architecture docs before changing a module boundary. Change architecture only when the item requires it. Otherwise preserve the documented boundaries and return any needed redesign to the caller.
- Follow
code-qualityfor implementation standards. - Follow
dev§ Round Contract and the delegated workflow for validation, commits and the completion artifact.
Output
What changed, which checks ran, their results, and any architecture change the caller must authorize.
Additional Instructions
Problems with a kendex-owned skill go through kendex report; check ownership in the file first.
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.

runtime is an agent published in the GitHub repository vanillagreencom/kendex (87 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 278 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-02.
