Document
name: v description: V simple systems programming language. Use for .v files.
V (Vlang)
V (2024 updates) focuses on compilation speed (1 million LOC/s) and safety (Autofree). It aims to be a modern C replacement with Go-like simplicity.
When to Use
- Fast Compilation: Iteration speed of an interpreted language.
- Graphics:
v uimodule provides a cross-platform UI toolkit. - No Dependencies: V is a single binary executable.
Core Concepts
Autofree
Compiler inserts free() calls automatically (experimental/improving).
C Interop
C.printf(). Direct calling of C functions.
Option/Result
fn foo() ?int. Error handling with or { ... }.
Best Practices (2025)
Do:
- Use
v fmt: Built-in formatter. - Use
v install: Built-in package manager. - Cross-compile: V makes outputting C for other platforms easy.
Don't:
- Don't use globals: V discourages mutable global state.

Repository README
Describes majiayu000/claude-skill-registry-data as a whole, which may contain artifacts other than this one. Where this artifact had no useful description of its own, its summary was taken from here.
Claude Skill Registry (Data)
This repo contains the archived skill contents (the heavy, browsable skill files).
Canonical layout
- Category folders at repo root (e.g.
development/,documents/,data/, ...) - Each skill lives under a category:
<category>/<skill>/SKILL.md+<category>/<skill>/metadata.json - Case conflicts are resolved with
{name}-{owner}-{repo}suffixes (fallback:-{short-hash}).
Archive status
- Live badges above are sourced from
claude-skill-registry-corestats.json. - Counts in this README are intentionally dynamic, not hardcoded.
- If the badges look stale, refresh the
corebuild/index pipeline rather than editing numbers here.
Where the index + site live
- Core repo: https://github.com/majiayu000/claude-skill-registry-core

Trustgrade B
- passBody integrity
Whether the stored document is plausibly the kind of file the artifact declares, rather than something fetched by mistake.
- passType matchnot applicable to this artifact type
Whether the artifact is really the kind of thing its metadata claims it is.
- passFreshness
How long since the source repository was last pushed to.
- passPrompt injection
Scans the artifact's own text for instructions aimed at your agent rather than at you.
- warnLicenseno SPDX license detected
Whether the source repository declares an SPDX license permissive enough to redistribute.
How the grade is calculated
Each check contributes 0 points when it passes, 1 when it warns, and 2 when it fails. The total maps to a letter:
- Aevery check passed
- Bone warning
- Ctwo warnings
- Dprompt injection or body integrity failed, or three warnings
- Fone of those failed, and something else is wrong
These are automated hygiene checks, not a security audit, and not a dependency or vulnerability scan. A grade of A means nothing was flagged — not that the artifact is safe.
