Build Safer Systems with Memory Safety Patterns

Memory errors and unsafe resource ownership can cause crashes, leaks, and data races. This skill applies proven patterns across C, C++, and Rust.

Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request
Review the Skillstore skill "memory-safety-patterns" from https://skillstore.io/skills/sickn33-memory-safety-patterns.md and its manifest at https://skillstore.io/api/skills/sickn33-memory-safety-patterns/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "memory-safety-patterns". Review a C function that allocates a buffer, opens a file, and returns early after errors.

Expected outcome:

  • High priority: centralize cleanup so every failure path releases the buffer and file.
  • Initialize resource handles before acquisition and release each resource only when valid.
  • Verify the change with allocation-failure tests and AddressSanitizer.

Using "memory-safety-patterns". Choose an ownership model for a C++ object shared by worker tasks.

Expected outcome:

  • Use unique ownership when one component controls the lifetime and workers borrow within a guaranteed scope.
  • Use shared ownership only when tasks must extend the lifetime independently.
  • Use weak references for observers to prevent ownership cycles.

What You Can Build

Review Systems Code

Identify ownership, lifetime, cleanup, bounds, and synchronization risks in a focused code review.

Design Resource Lifecycles

Choose RAII, smart pointers, or explicit cleanup for files, sockets, memory, and locks.

Learn Rust Ownership

Understand moves, borrowing, lifetimes, reference counting, and thread-safe shared state through practical examples.

Try These Prompts

Explain a Memory Safety Pattern 
Explain how [pattern] prevents [memory bug]. Include one concise example in [language] and list its main tradeoffs.
Review Resource Cleanup 
Review this [C or C++] resource lifecycle. Find leak, double-free, and exception-safety risks, then recommend specific cleanup changes.
Compare Ownership Designs 
Compare RAII, reference counting, and Rust ownership for this component: [description]. Recommend one model based on concurrency and lifetime needs.
Audit Concurrent Memory Safety 
Audit this concurrent systems code for data races, invalid lifetimes, lock misuse, and unsafe sharing. Prioritize findings and propose verification steps.

Best Practices

  • State the resource owner and expected lifetime before selecting a pattern.
  • Provide the relevant code, language version, concurrency model, and failure behavior.
  • Verify recommendations with compiler warnings, sanitizers, and targeted tests.

Avoid

  • Do not assume smart pointers automatically make object graphs cycle free.
  • Do not use unchecked access or unsafe blocks without a documented invariant.
  • Do not apply examples unchanged without checking project APIs and error handling.

Frequently Asked Questions

Which languages does this skill cover?
It focuses on C, C++, and Rust, with general guidance that also applies to other systems languages.
Can this skill prove my program is memory safe?
No. It provides patterns and review guidance, but verification still requires testing, analysis tools, and project-specific review.
Does the skill run AddressSanitizer or Valgrind?
No. It can recommend commands and interpret supplied results, but it does not run tools by itself.
Can it help migrate raw pointers to smart pointers?
Yes. It can map ownership roles and recommend unique, shared, or weak pointers based on actual lifetime requirements.
Does it cover concurrent memory safety?
Yes. It explains atomics, mutexes, read-write locks, thread-safe sharing, and Rust data race prevention.
What context improves the review?
Provide the code, language version, ownership expectations, thread model, error paths, and available test or sanitizer results.
