What it does
Cpp String API Review is an agent skill from tetherto/qvac. Review C++ changes for string parameter and call-site efficiency conventions (std::stringview, std::string&&, const std::string&, const char, and TransparentStringMap lookup). Use when reviewing C++ code, refactoring addon interfaces, or invoking /cpp-string-api-review.
Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in AI & LLM Engineering, covering Refactoring. It works with C++. The repository describes itself as: Open-source local AI SDK - run AI on-device with no cloud, no API keys. Supports GGUF, RAG, image, music, and video generation, speech-to-text, P2P inference, and more… The licence is Apache-2.0.
When your agent uses it
- Reviewing C++ code
- Refactoring addon interfaces
- Invoking /cpp-string-api-review
Example prompts
- “/cpp-string-api-review”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Identify touched C++ files (*.h, *.hpp, *.cc, *.cpp, *.cxx) in scope.
- Inspect string parameters and classify each as
- Flag cost/correctness issues
- Check for requirement propagation ("requirements bubble up")
- Produce findings grouped by severity
- Propose precise edits with before/after snippets. Only apply code changes after explicit user confirmation.
What it can do on your machine
Read from SKILL.md and the folder at commit d92f697. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cpp String API Review loads about 702 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 249 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

C++ String API Review
Review C++ code for string API convention compliance and produce actionable fixes.
When to use this skill
Use when:
- User asks for a review of C++ string parameter choices.
- User asks to migrate existing code toward string API conventions.
- User invokes
/cpp-string-api-review.
Do NOT use for:
- Non-C++ changes.
- Broad performance review unrelated to string interfaces.
Scope and source of truth
- Primary reference:
docs/conventions/string-api-conventions.md - Supporting implementation reference:
packages/inference-addon-cpp/src/inference-addon-cpp/TransparentStringMap.hpp
Review workflow
- Identify touched C++ files (
*.h,*.hpp,*.cc,*.cpp,*.cxx) in scope. - Inspect string parameters and classify each as:
- read-only non-owning (
std::string_view), - sink ownership transfer (
std::string&&), - downstream compatibility (
const std::string&), - C boundary (
const char*).
- read-only non-owning (
- Flag cost/correctness issues:
- read-only
const std::string&wherestd::string_viewis sufficient, - sink modeled as
const std::string&+ copy instead ofstd::string&&+ move, - hidden temporary conversions (
std::string{view}) on hot paths, - unsafe
view.data()usage where null termination is not guaranteed, - avoidable temporary key materialization in map lookups.
- read-only
- Check for requirement propagation ("requirements bubble up"):
- if a wrapper takes
std::string_viewbut must call aconst std::string&API, surface the trade-off and propose the correct boundary.
- if a wrapper takes
- Produce findings grouped by severity:
- High: correctness/lifetime/null-termination issues,
- Medium: hidden alloc/copy churn in common paths,
- Low: style/consistency improvements.
- Propose precise edits with before/after snippets. Only apply code changes after explicit user confirmation.
Output format
Use this structure:
## C++ String API Review
### Findings
- [High|Medium|Low] <short title> — <file/symbol>
- Why it matters: <cost/correctness impact>
- Suggested change: <concise fix>
### Recommended edits
1. <edit 1>
2. <edit 2>
### Notes
- <boundary trade-offs, if any>Quick heuristics
- Prefer explicit ownership intent over hidden conversions.
- Prefer leaf-first migration to
std::string_viewthrough call chains. - If downstream requires
const std::string&, do not hide that cost behind wrapper layers.
