Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.11046 | $0.11046 |
| Opus 5 | $0.05523 | $0.05523 |
| Sonnet 5 | $0.02209 | $0.02209 |
| Haiku 4.5 | $0.01105 | $0.01105 |
Grade A, and why
OpenTagViewer AGENTS.md 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 801 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Rules for agents working on OpenTagViewer. Written for automated contributors, but the constraints apply to anyone.
This file is owned and maintained by agents, and keeping it current is part of the work rather than a favour to whoever comes next. @parawanderer asked for that and has not read it since. No human reviews what lands here, so the agent writing a change is the only check on it.
What that means in practice:
- If you learned something the hard way, write it down in the same change that taught you. The next agent starts here, and anything left out is an afternoon they pay for and you did not.
- The reason travels with the rule. An instruction with no reasoning attached is one a later agent deletes the first time it looks inconvenient. That is why the entries here argue.
- Earn it. Nobody is filtering this, so a rule that has not actually cost somebody something does not belong. Rule 10 has the test.
- Do not carry this register outside the repository. It is written for agents who need to be argued out of breaking something. A pull request review, an issue reply, or anything else a person reads is a different job. See rule 16.
What this project is
An Android app that shows Apple AirTag locations without an Apple device. Tags are exported from a Mac once (see the wiki), imported as a zip, and located via Apple's Find My network through FindMy.py.
| Layer | Technology |
|---|---|
| App | Android, Java (not Kotlin), Gradle Kotlin DSL, compileSdk/targetSdk 35, minSdk 24 |
| Apple protocol | Chaquopy — CPython 3.12 embedded, bridged in app/src/main/python/main.py |
| Persistence | Room (opentagviewer-db) |
| Async | RxJava3 through repositories and services |
| Boilerplate | Lombok (@Builder, @Getter on entities) |
| Desktop exporter | python/ — tkinter wizard, PyInstaller |
app/src/main/python/ is packaged into the APK by Chaquopy. Nothing in it may import
Android or Java types — that is what makes it testable on plain CPython.
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.

OpenTagViewer AGENTS.md is an instructions file published in the GitHub repository parawanderer/OpenTagViewer (372 stars, last pushed 3d ago), licensed MIT. It adds 11,046 tokens to every session, about $0.0552 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.
