adopt-c-bounds-safety SKILL.md skillA

adopt-c-bounds-safety from tartinerlabs/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add tartinerlabs/skills/adopt-c-bounds-safety@git:20260713.ba4f7f8

Pins git:20260713.ba4f7f8 in mdr.lock. Pin the fingerprint instead.

Guide for the C -fbounds-safety language extension. Covers the language model, pointer annotations, adopting bounds-safety in existing C code, compiler build settings and modes, and runtime debugging of bounds violations.

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

## 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:
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add tartinerlabs/skills/adopt-c-bounds-safety@sha256:531fd0d74a769801

The line at the top of this page pins the label git:20260713.ba4f7f8, 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.
