# Send C++ to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

### Quick Reference

TopicFileRAII, smart pointers, new/deletememory.mdRaw pointers, references, nullptrpointers.mdRule of 3/5/0, inheritance, virtualclasses.mdContainers, iterators, algorithmsstl.mdTemplates, SFINAE, conceptstemplates.mdThreads, mutex, atomicsconcurrency.mdC++11/14/17/20, move semanticsmodern.mdUndefined behavior trapsub.md

### Critical Rules

Raw new without delete leaks — use std::unique_ptr or std::make_unique
Returning reference to local — undefined behavior, object destroyed on return
== for C-strings compares pointers — use std::string or strcmp()
Signed integer overflow is UB — not wrap-around like unsigned
Virtual destructor required in base class — otherwise derived destructor skipped
std::move doesn't move — it casts to rvalue, enabling move semantics
Moved-from object valid but unspecified — don't use without reassigning
Data race on non-atomic is UB — use std::mutex or std::atomic
vector<bool> is not a real container — returns proxy, use deque<bool>
map[key] inserts default if missing — use find() or contains() to check
Braced init {} prevents narrowing — int x{3.5} errors, int x(3.5) truncates
Iterator invalidation on push_back — vector may relocate, invalidating iterators
string_view doesn't own data — underlying string must outlive the view
