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 | $0.00182 | $0.00182 |
| Opus 5.5 | $0.00073 | $0.00073 |
| Sonnet 5.5 | $0.00036 | $0.00036 |
| Haiku 4.5 | $0.00018 | $0.00018 |
Grade C, and why
kendex tests.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 21d 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.
<!-- generated by bot-instructions 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-render. What it actually says
The -- rule covers paths from configuration, arguments, or the environment. Its absence on a fixture path that the test creates is not a finding.
A scratch directory removed by the test's EXIT trap is cleaned up. Do not report it as a leak.
${arr[@]+"${arr[@]}"} is the quoted empty-array expansion used with Bash 3.2 and set -u. Do not report it as unquoted expansion or word splitting.
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.
