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 | $0.00082 | $0.02309 |
| Opus 5 | $0.00041 | $0.01154 |
| Sonnet 5 | $0.00016 | $0.00462 |
| Haiku 4.5 | $0.00008 | $0.00231 |
Grade A, and why
ui-developer 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

AGENTS-REFERENCE
This file lists all 20 agents in the complete system. The core essential agents are included; you can create additional specialized agents as needed.
build-doctor
Native build failure specialist for React Native projects. Delegate when an iOS or Android build fails and the fix may take several investigation rounds, or when a long build log needs to be dug through without flooding the main conversation.
crash-analyst
Production crash and error-report investigator for React Native apps. Delegate when there is a Sentry event, a minified Hermes stack trace, a tombstone, or a user-reported crash to trace back to source and root cause.
perf-auditor
Read-only performance auditor for React Native codebases. Delegate when the app feels slow and the code should be swept for list, re-render, animation and startup antipatterns without making any edits.
release-checker
Pre-submission auditor for React Native releases. Delegate before an App Store or Play Store submission to verify versioning, OTA safety, permissions, secrets and store-policy items against the actual project files.
version-manager
Specialized agent for all version number management — bumping, syncing, validating iOS and Android version codes across app.json, Info.plist, and build.gradle.
