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 | $0.00402 | $0.00402 |
| Opus 5.5 | $0.00161 | $0.00161 |
| Sonnet 5.5 | $0.00080 | $0.00080 |
| Haiku 4.5 | $0.00040 | $0.00040 |
Grade C, and why
kendex copilot-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.

kendex
kendex has a desktop app and CLI over a shared Rust core. It distributes skills, agent definitions, hooks, and Pi extensions to coding tools. The app uses Tauri and React. Pi extensions include source files and committed bundles.
Code review
The complete review doctrine for this repository, the reply contract included, is in .github/instructions/code-review.md. Read that file before you comment.
severity
Mark a finding as blocking only if it must stop the merge. Mark other findings as suggestions. Group suggestions together. Omit suggestions when a repeat review covers a one-line fix. Match severity and confidence to the evidence. Name the user-visible consequence in every finding.
Approve the pull request when the review reports no finding, and when every finding it reports is a suggestion or a nit. Withhold approval only for a blocking finding, and name that finding in the review. Do not withhold approval for a concern you cannot state as a finding. On a later review, a finding the author answered under the reply contract does not block approval unless the code it names changed after the answer.
Copilot code review reviews each new head on a push. Copilot re-reads a head only on a review request. The vanillagreen-overseer GitHub App can approve a head that no review bot approves and whose findings the author answered under the reply contract, in their threads or in a Dispositions at <sha> comment. The conditions for that approval are the KEN-2067 design note, attached to that issue, § Copilot-down fallback.
Path rules
Per-path review rules live in .github/instructions/, one file per path set.
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.
