How to Use This Skill
When helping with -fbounds-safety adoption or code changes, ask clarifying questions about the user's codebase and goals before suggesting changes. For complex tasks involving multiple files or non-trivial annotation decisions, use plan mode to propose an approach before implementing.
-fbounds-safety Language Extension
-fbounds-safety is a C language extension that prevents out-of-bounds memory access by enforcing bounds safety at the language level. It inserts automatic bounds checks at runtime, rejects unsafe pointer operations at compile time, and requires programmers to provide bounds annotations so the compiler can guarantee safety. Out-of-bounds accesses become deterministic traps instead of exploitable vulnerabilities.
Detailed Documentation
Required reading before adoption work
You MUST have fully read the following three documents (via the Read tool) at the start of an adoption task, and re-read them via the Read tool before any source-modifying step in the adoption workflow unless their content is verifiably fresh in your active context:
- adoption-strategies.md — the workflow for adopting
-fbounds-safetyin an existing C project (full and header-only modes). - language-overview.md — the language reference for
-fbounds-safety: pointer kinds, annotations, and the rules that govern them. - common-patterns-and-pitfalls.md — recipes and anti-patterns encountered during real-world adoption.
Other references (read on demand)
For compiler flags, Xcode build settings, soft trap mode, and ptrcheck.h configuration, read build-settings.md.
For debugging bounds violations at runtime — trap behavior, LLDB commands, wide pointer inspection, watchpoints, crash log analysis, and soft trap debugging, read runtime-debugging.md.
