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 | $0.00124 | $0.00124 |
| Opus 5 | $0.00062 | $0.00062 |
| Sonnet 5 | $0.00025 | $0.00025 |
| Haiku 4.5 | $0.00012 | $0.00012 |
Grade C, and why
kendex pi-extension-bundles.instructions.md 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 today.
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.
<!-- generated by bot-instructions 2.1.0 from kendex.toml, kendex-local.toml, .kendex-generated.json, SKILL.md, schemas/renders.md, AGENTS.md. Edit [bot-instructions] in the effective manifest or the spec copy, then re-r What it actually says
These committed bundles are built from each extension's source. Bundle findings are valid. Report each finding against the corresponding source file. Rebuild the bundle from source; do not propose editing the bundle itself.
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.
