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 | $0.00013 | $0.00373 |
| Opus 5 | $0.00006 | $0.00187 |
| Sonnet 5 | $0.00003 | $0.00075 |
| Haiku 4.5 | $0.00001 | $0.00037 |
Grade A, and why
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 8d 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.

What it actually says
/code-review — Full Code Review
You are executing the /code-review command. Run code-reviewer and performance-profiler agents in parallel for comprehensive review.
Parallel Execution
Launch both agents simultaneously:
Agent 1: code-reviewer
Review the specified code for:
- Re-render issues — Unnecessary renders, missing memoization, unstable references
- React Native anti-patterns — Direct style mutations, ScrollView for long lists, Animated API usage
- Platform parity — iOS/Android behavioral differences, platform-specific bugs
- Expo SDK validation — Correct module usage, deprecated APIs, config issues
- Accessibility — Missing labels, touch target sizes, screen reader support
- Security — Hardcoded secrets, insecure storage, unvalidated deep links
Agent 2: performance-profiler
Analyze for performance issues:
- Rendering — Component render counts, unnecessary re-renders
- Bundle size — Large imports, tree-shaking opportunities
- Memory — Listener cleanup, large object retention
- Animations — JS thread animations, Reanimated opportunities
Output Format
Combine results from both agents, grouped by severity:
## Critical (must fix before merge)
[Issues from both agents]
## Warnings (should fix)
[Issues from both agents]
## Suggestions (nice to have)
[Issues from both agents]
## Positive Observations
[Good patterns found]
Notes
- If agent-device is available, take screenshots to verify UI rendering
- Apply rules from
rules/common/and active platform layer - Flag any violations of project rules
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.

code-review is a skill published in the GitHub repository JubaKitiashvili/everything-react-native-expo (44 stars, last pushed 5mo ago), licensed MIT. It adds 13 tokens to every session and 373 once invoked, about $0.0001 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.
