trailofbits Bundle

Uses mutation testing to systematically identify gaps in test vector coverage for cryptographic algorithms, then generates new test vectors that close those gaps. Measures effectiveness by comparing mutation kill rates before and after.

trailofbits Bundle

Fuzz C/C++ projects with multi-core support using AFL++, a fork of AFL with better performance and advanced features.

trailofbits Bundle

trailofbits Bundle

Patch code to bypass checksums, global state, and validation checks that block fuzzer progress, using conditional compilation for C/C++ and Rust.

trailofbits Bundle

Guides fuzzers with domain-specific tokens to reach deeper code paths in parsers, protocol handlers, and file format processors.

trailofbits Bundle

Provides guidance for property-based testing across multiple languages and smart contracts, helping detect patterns where PBT offers stronger coverage than example-based tests.

Validate skill outputs against assertion manifests to detect regressions, enforce quality gates, and bootstrap starter manifests from historical runs.

bankrbot Bundle

Write and run smart contract tests with Foundry, covering unit, fuzz, fork, and invariant testing, with guidance on what to test and common LLM pitfalls.

k-dense-ai Bundle

Build discrete-event simulations of systems with processes, queues, resources, and time-based events using SimPy in Python.

mcollina Bundle

Provides domain-specific best practices for Node.js development with TypeScript, covering type stripping, async patterns, error handling, streams, modules, testing, performance, caching, logging, and more.

mcollina Bundle

Guides development of Fastify Node.js backend servers and REST APIs using TypeScript or JavaScript, covering routes, plugins, validation, error handling, authentication, testing, performance, logging, deployment, and more.

wondelai Bundle

Write readable, maintainable code through disciplined naming, small functions, and clean error handling.

wondelai Bundle

Safely change and test untested codebases using techniques from Feathers' 'Working Effectively with Legacy Code': seams, characterization tests, sprout/wrap, and dependency-breaking.
