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 | $0.00055 | $0.00950 |
| Opus 5 | $0.00028 | $0.00475 |
| Sonnet 5 | $0.00011 | $0.00190 |
| Haiku 4.5 | $0.00006 | $0.00095 |
Grade A, and why
watchos-code-review 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.

Review Checklist
- SwiftUI App protocol used with
@WKApplicationDelegateAdaptorfor lifecycle events -
scenePhaseread from root view (not sheets/modals where it's always.active) -
WKExtendedRuntimeSessionstarted only while app is active (not from background) - Workout sessions recovered in
applicationDidFinishLaunching(not just delegate) - Background tasks scheduled at least 5 minutes apart; next scheduled before completing current
-
URLSessionDownloadTask(notDataTask) used for background network requests - WidgetKit used instead of ClockKit for watchOS 9+ complications
- Timeline includes future entries (not just current state); gaps avoided
-
TimelineEntryRelevanceimplemented for Smart Stack prioritization - WCSession delegate set before
activate(); singleton pattern used -
isReachablechecked beforesendMessage;transferUserInfofor critical data - Received files moved synchronously before delegate callback returns
When to Load References
- Reviewing app lifecycle, background modes, or extended sessions -> lifecycle.md
- Reviewing complications, widgets, or timeline providers -> complications.md
- Reviewing WCSession, iPhone-Watch communication -> connectivity.md
- Reviewing memory, battery, or performance issues -> performance.md

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

watchos-code-review is a skill published in the GitHub repository Project-Kiri/Kiri-Friends (11 stars, last pushed 3mo ago), licensed MIT. It adds 55 tokens to every session and 950 once invoked, about $0.0003 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.
