Expensify/App is the source code for New Expensify, a financial collaboration application organized around chat. It is used by contributors building and testing the web, iOS, and Android versions of the application. Catalogue add-ons support development workflows such as mobile testing and agent-assisted work on the codebase.

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 | $0.00034 | $0.00161 |
| Opus 5.5 | $0.00014 | $0.00064 |
| Sonnet 5.5 | $0.00007 | $0.00032 |
| Haiku 4.5 | $0.00003 | $0.00016 |
Grade A, and why
review-code-pr 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 1mo 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
Perform a comprehensive PR review using a specialized subagent:
Inline Review
Use the code-inline-reviewer agent to:
- Scan all changed source code files
- Detect review rule violations with line-specific, actionable feedback
Run the agent. It will return structured JSON with any violations found.
Output
Return the subagent's violations JSON as your structured output unchanged. Do NOT post comments or reactions yourself - the workflow handles that.
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.

review-code-pr is a command published in the GitHub repository Expensify/App (5,081 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 161 once invoked, about $0.0001 per session on Opus 5.5. 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.
