Generates fuzz test scaffolding for parsers handling external input (YAML, JSON, config files, user input). Seeds corpus from existing fixtures and runs initial pass. Use when implementing or changing a parser, or any code that ingests user input, webhook payloads, API responses, or file formats.
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
# vibe-fuzz-parser-inputs
Every parser will eventually see input you didn't expect. Fuzz testing finds the crashes before production does.
## When to Use This Skill
- Implementing any parser (YAML, JSON, XML, config, DSL)
- Processing user-supplied input
- Handling webhook payloads or API responses
- Parsing file formats
## When NOT to Use This Skill
- The parser is a well-tested standard library (e.g., `encoding/json`)
- You're only reading known, controlled input
- The parser is trivial (e.g., splitting a string by comma)
## Steps
### Go Fuzz Tests
1. **Create fuzz test file** (`parser_fuzz_test.go`):
```go
func FuzzParseConfig(f *testing.F) {
// Seed corpus from existing test fixtures
files, _ := filepath.Glob("testdata/*.yaml")
for _, file := range files {
data, _ := os.ReadFile(file)
f.Add(data)
}
// Add targeted seeds
f.Add([]byte("")) // empty
f.Add([]byte("{}")) // minimal valid
f.Add([]byte("\x00\x00")) // binary
f.Fuzz(func(t *testing.T, data []byte) {
// Should never panic
result, err := ParseConfig(data)
…Read the whole file at its exact version.
How to install
mdr add ash1794/vibe-engineering/vibe-fuzz-parser-inputs@sha256:64346911124e9627The line at the top of this page pins the label git:20261007.24cccad, 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.
