Libafl
Skill ActiveLibAFL is a modular fuzzing library for building custom fuzzers. Use for advanced fuzzing needs, custom mutators, or non-standard fuzzing targets.
To provide a powerful and flexible Rust library for developers and security researchers to build custom fuzzing tools for advanced needs, novel techniques, or non-standard targets.
Features
- Modular fuzzing library in Rust
- Customizable fuzzing components (observers, mutators, schedulers)
- libFuzzer drop-in replacement
- Build custom fuzzers from scratch
- Extensive examples and troubleshooting guide
Use Cases
- Building advanced fuzzing strategies beyond standard tools
- Implementing novel fuzzing techniques for research
- Fuzzing non-standard architectures or complex targets
- Replacing existing libFuzzer setups with a more modular backend
Non-Goals
- Providing a ready-to-use end-user fuzzer application
- Automating the entire fuzzing campaign setup without user intervention
- Fuzzing simple targets that are adequately covered by standard tools like libFuzzer or AFL++
Documentation
- info:Configuration & parameter referenceWhile the SKILL.md details installation and compilation flags, it does not explicitly document default values for all possible configuration parameters or their precedence order.
Trust
- warning:Issues AttentionIn the last 90 days, 13 issues were opened and 4 were closed, indicating a low closure rate and potentially slow maintainer response.
Errors
- info:Actionable error messagesWhile Rust's error handling is generally good, the SKILL.md focuses on build and usage instructions rather than detailing specific error messages and their remediation steps for user-facing issues.
Practical Utility
- info:Edge casesThe troubleshooting section addresses common problems and their solutions, but explicit documentation of all failure modes and recovery steps for the LibAFL library itself is not comprehensive.

Senior Backend Engineer
100Designs and implements backend systems including REST APIs, microservices, database architectures, authentication flows, and security hardening. Use when the user asks to "design REST APIs", "optimize database queries", "implement authentication", "build microservices", "review backend code", "set up GraphQL", "handle database migrations", or "load test APIs". Covers Node.js/Express/Fastify development, PostgreSQL optimization, API security, and backend architecture patterns.
LibFuzzer
95Coverage-guided fuzzer built into LLVM for C/C++ projects. Use for fuzzing C/C++ code that can be compiled with Clang.
Lean Ctx
100Context Runtime for AI Agents — 59 MCP tools, 10 read modes, 95+ shell patterns, tree-sitter AST for 18 languages. Compresses LLM context by up to 99%. Use when reading files, running shell commands, searching code, or exploring directories. Auto-installs if not present.
Cleanup Cycles
100Detect and untangle circular dependencies. Runs madge/skott (TS), pycycle (Py), or compiler-only checks (Go/Rust). Auto-fixes leaf-extractable cycles; reports core cycles for human review. Use when the user asks to find circular imports, fix dependency cycles, or untangle module graph. Example queries — "find circular imports", "fix dependency cycles", "untangle our module graph", "why is madge complaining".
Running Tend
100Worktrunk-specific guidance for tend CI workflows. Adds codecov polling, Rust test commands, labels, and review criteria on top of the generic tend-* skills. Use when operating in CI.
Secrets Management
100Implement secure secrets management for CI/CD pipelines using Vault, AWS Secrets Manager, or native platform solutions. Use when handling sensitive credentials, rotating secrets, or securing CI/CD environments.
