hermes-crashes from anilburcu/claude-code-react-native is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Decoding Hermes crashes and minified production stack traces. Use for "address at index.android.bundle" frames, unsymbolicated or badly grouped Sentry events, SIGSEGV in libhermes, ANRs, source maps.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Making production crashes readable ## First, classify the crash Three families, three completely different investigations: 1. **JS error**: a thrown Error, a rejected promise, a render error. Stack frames point into the JS bundle (`index.android.bundle`, `main.jsbundle`). Fix in JS. 2. **Native crash**: SIGSEGV, SIGABRT, EXC_BAD_ACCESS, frames in `libhermes.so` or platform frameworks. The JS code may be the trigger but the defect is in a native module or in JSI usage. 3. **ANR / watchdog kill**: no crash at all, the main thread was blocked. Investigate what ran long, not what threw. Misclassifying wastes days. A SIGSEGV cannot be fixed by editing JavaScript, and an unhandled rejection will never appear in a tombstone. ## Decoding "address at index.android.bundle:1:589926" That address is an offset into Hermes bytecode, not a line and column in your source. The decoder is metro-symbolicate plus the source map that was generated for that exact build: ```bash # paste the raw stack into a file, then: npx metro-symbolicate path/to/index.android.bundle.map < stack.txt ``` Rules that make this work: …

How to install
mdr add anilburcu/claude-code-react-native/hermes-crashes@sha256:e5aae527c86867a2The line at the top of this page pins the label git:20260911.98ac3cb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
