pamsignal

Professional C programming craft for the PAMSignal project — clean code, idiomatic modern C (C17/gnu17), memory safety patterns, defensive programming, error-handling discipline, and refactoring guidance. Use this skill whenever writing, editing, reviewing, or refactoring any `.c` or `.h` file in this project, even for small changes or one-line fixes. Triggers on adding new functions, modifying existing C code, extracting helpers, fixing bugs in C, introducing new modules, or any work that produces or modifies C source. Also triggers on phrases like "clean up this C", "make this safer", "refactor this function", "review this C code", "is this idiomatic". Complements `senior-linux-developer` (Linux systems persona) and `owasp-asvs` (security verification) by owning the craft layer — how the code is written, not just what it does.

Project-aware OWASP ASVS 5.0 audit skill for PAMSignal — a C17/gnu17 daemon that monitors PAM events via systemd journal and dispatches alerts via fork+exec curl. Use when reviewing code against the Application Security Verification Standard — full audit (with N/A chapters explicitly marked), single-chapter deep dive, or level-targeted compliance check (L1 baseline, L2 standard, L3 high-assurance). Triggers on English requests like "ASVS audit", "OWASP ASVS review", "L1 compliance", "verify V1 encoding", "ASVS V15 secure coding review", "security verification", "is this ASVS-compliant". Also triggers on Vietnamese requests like "rà soát ASVS", "đánh giá OWASP ASVS", "kiểm tra ASVS V15", "compliance bảo mật". Each chapter has a dedicated reference file under `references/` with the V-ID list, project-specific evaluation guide pointing at the actual PAMSignal code surfaces (sanitize_string, is_valid_ip, json_escape, validate_tls_path, ps_is_trusted_exe, build_secrets_memfd, fork+exec curl, O_NOFOLLOW|O_EXCL, mes

Senior Linux systems programmer persona. Deep expertise in C (gnu17), PAM, systemd, POSIX, Linux security, CERT C, CWE prevention, FHS compliance, and distribution packaging (deb/rpm/AUR). Auto-invoke when writing or reviewing C code, systemd units, build configs, or packaging files.

Generate Linux distribution package specs (deb and rpm) for the pamsignal project. Use this skill whenever the user mentions packaging, .deb, .rpm, dpkg, apt, dnf, yum, creating packages, release packaging, debian directory, spec files, or wants to distribute pamsignal for Debian, Ubuntu, Fedora, CentOS, AlmaLinux, or Rocky Linux. Also trigger when the user asks about install/uninstall scripts, maintainer scripts, or package metadata for this project.
