vela

vela is a skill for Claude Code from dbhq-uk/vela-skill. It costs 213 tokens per session (1,471 once invoked), scanned A, original, MIT.

A compiler-aware search tool for .NET code, including C#, Visual Basic, Razor Pages, MVC views, and Blazor components. It uses the code's meaning to find definitions, references, callers, and likely breakage from a change.

In plain words
What is it for?
It helps find where a .NET symbol is defined, locate every meaningful reference and caller, include references in Razor and Blazor files, and assess what a change may break.
Why use it?
Plain text search can return many unrelated matches and cannot reliably show which symbol a reference belongs to. This makes it easier to understand the impact of changing common names.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vela scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

vela

Compiler-exact code search over a SCIP index. .NET answers come from Roslyn, other languages from their own indexers' .scip files. It never writes to the repository.

Which tool

  • grep when the name is distinctive. It is free and needs no index.
  • The LSP tool, where your host has one, for code you have just edited. It stays live, where vela needs a re-index, which takes minutes on a large solution.
  • vela for:
    • ordinary names (Name, Status, Id), where grep is mostly noise and vela reports when a name is ambiguous
    • references from .cshtml and .razor files
    • callers, implementations, and what a change touches
    • a survey of a clean tree before a change
  • Not vela in a repository with no .NET and no .scip to import.

Steps

0. Check the command is installed

command -v vela

Plugin and skills.sh installs copy this file, not the command. If it prints nothing, tell the user rather than quietly falling back to grep. vela needs:

  • the .NET SDK 10.0 or newer
  • the tool itself: clone https://github.com/dbhq-uk/vela-skill and run ./install.sh
  • ~/.dotnet/tools on PATH

1. Build the index

vela does not restore packages. Run dotnet restore first if the solution has never been built.

vela index

vela uses the solution vela.json names, or else the only .sln or .slnx here or in the nearest directory above, up to the repository root. If it cannot pick one, pass --solution <path> to every command.

Indexing costs about what a build costs. Re-index after every code change: once a watched file is newer than the index, answers carry the stale banner. vela index --incremental rebuilds only what changed. Index without it before you delete or rename anything.

If a project fails to load or compile, vela says so, and whatever depended on it is missing.

2. Add other languages

vela import path/to/index.scip             # first time
vela import --replace path/to/index.scip   # after re-running that indexer

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
