What it does
Neva Language is an agent skill from nevalang/neva. Use for Neva source or snippets: authoring, refactoring, debugging, or review.
Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Refactoring. The repository describes itself as: Dataflow programming language where you write a program as a message-passing graph and everything runs in parallel by default. It has strong static types, compiles to machine… The licence is MIT.
When your agent uses it
- Snippets: authoring
- Tasks that involve Refactoring
Example prompts
- “/neva-language”
What it can do on your machine
Read from SKILL.md and the folder at commit 127afd9. 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
Shell commands in SKILL.md call:
go
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
Neva Language loads about 270 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 125 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.

Neva Language
Use this skill for changes touching *.neva or Neva code snippets.
CLI Discovery
- Use
neva --helpto list commands and global options. - Use
neva <command> --helpbefore relying on a command's flags or argument contract. - During repository development, run
go run ./cmd/neva --helporgo run ./cmd/neva <command> --helpwhen a local binary is unavailable. neva doc [package/path] [.] <pattern>searches the bundled standard library; use it to discover existing components before adding one.
Rules
- Read
docs/user/style_guide.mdbefore editing. - Keep edited
.nevafiles syntactically valid. - If syntax is uncertain, consult
internal/compiler/parser/neva.g4and nearby.nevaexamples before editing. - When feasible, validate changed Neva programs by compiling or running them.
- When editing documentation or snippets, prefer a quick local compile/run check of an equivalent minimal example.
