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 | $0.00072 | $0.01792 |
| Opus 5 | $0.00036 | $0.00896 |
| Sonnet 5 | $0.00014 | $0.00358 |
| Haiku 4.5 | $0.00007 | $0.00179 |
Grade A, and why
rn-asset-hygiene 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 11d 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.

RN Asset Hygiene — Audit & Tidy React Native Assets
Overview
Drives the rn-typed-assets CLI to (1) report unreferenced/unused assets and scattered asset paths, and (2) optionally consolidate those paths and migrate brittle require('../../assets/x.png') strings into a typed registry.
This skill is the judgment + safety layer; rn-typed-assets does the deterministic scanning, codegen, and rewriting.
Nothing in your source or assets changes until you approve it — audit is read-only, and the registry + manifest that generate writes land under src/generated/.
When to Use
- "find unused images/assets", "clean up asset paths", "is this asset still bundled?"
- Onboarding a legacy RN app whose
assets/folder has grown out of control - Trimming dead weight from the bundle before a release
- Migrating string
require()asset references to type-safe constants
Prerequisites
- A React Native project using TypeScript (the audit uses the TS compiler API;
typescriptis a peer dependency ofrn-typed-assets) - A clean git working tree before any mutation step (steps 5+)
- Metro does not need to be running — this is static analysis
Quick Steps
1 — Detect the asset layout & SVG setup
ls src/assets 2>/dev/null # where assets live
grep -R "react-native-svg-transformer" metro.config.* 2>/dev/null # decides SVG config below
2 — Configure SVG typing (no install needed)
Every rn-typed-assets command below runs through npx, so auditing adds nothing to package.json — installing it as a devDependency is part of adopting the tool (see Distribution), not of taking a first look.
If the project renders SVGs, create rn-typed-assets.config.js (see SVG Type Configuration) so the generated registry types them correctly.
Skip it for an images-only project or if the file already exists.
3 — Generate the manifest (writes generated files only; does not touch source)
npx rn-typed-assets generate
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.

rn-asset-hygiene is a skill published in the GitHub repository AndrewDongminYoo/rn-agents-kit (2 stars, last pushed 7d ago), licensed Apache-2.0. It adds 72 tokens to every session and 1,792 once invoked, about $0.0004 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 2026-08-31.
