corvus-codegenGenerate strongly-typed C from JSON Schema using the Roslyn source generator or the corvusjson CLI tool.
Corvus Codegen is an agent skill from corvus-dotnet/Corvus.JsonSchema. Generate strongly-typed C from JSON Schema using the Roslyn source generator or the corvusjson CLI tool. Covers the JsonSchemaTypeGenerator attribute, CLI options, naming heuristics, AdditionalFiles registration, config file format, MSBuild properties, and troubleshooting generated output. USE FOR: generating types from schemas, configuring the source generator or CLI tool, understanding naming heuristics, inspecting generated output, troubleshooting generation issues. DO NOT USE FOR: modifying the generator…
Its SKILL.md is about 2.1k 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 Project scaffolding. It works with C#. The repository describes itself as: Support for Json Schema validation and entity generation. The licence is Apache-2.0.
2 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 51cc725. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
dotnetFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Corvus Codegen loads about 2.1k tokens when it runs. Until then it costs about 155 tokens; SKILL.md has 688 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.
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.

corvusjson jsonschema <schema-path> `
--rootNamespace MyApp.Models `
--outputRootTypeName PersonSchema `
--outputPath Generated/ `
--engine V5The command is corvusjson jsonschema (registered in CliAppFactory.cs).
Key CLI options (defined in src/Corvus.Json.Cli.Core/GenerateCommand.cs):
--rootNamespace — C# namespace for generated types--outputRootTypeName — name of the root generated type--outputPath — output directory--engine — V4 or V5 (default: V5 for corvusjson, V4 for legacy generatejsonschematypes)--assertFormat — whether format validation asserts globally (default: true). Takes a value: --assertFormat false gives annotation-only output where the vocabulary treats format as an annotation (e.g. 2020-12)--formatMode — format assertion mode overrides as comma-separated entries (mode ∈ assert/disable/warning). format=mode targets one format (e.g. date-time=disable,time=warning); a bare mode (equivalently *=mode) sets the default for all formats across every draft — --formatMode disable is the way to get annotation-only output for draft-04/06/07 (whose vocabulary asserts format, so --assertFormat false alone doesn't). Repeatable; a per-format override beats the * default, --assertFormat, and the vocabulary. warning (string formats only) validates but always succeeds, emitting a WARNING annotation on mismatch--codeGenerationMode — TypeGeneration, SchemaEvaluationOnly, or Both--nativeEnums — native C# enum emission (V5 engine only, default All): StringEnums emits a nested KnownValues enum for pure string-enum schemas; FlagsObjects emits a nested [Flags] enum for objects whose declared properties are all boolean; All emits both; None emits neitherIMPORTANT: Never invent option names. Verify against
GenerateCommand.cs.
The generatejsonschematypes command (package: Corvus.Json.CodeGenerator) still works as a shim but defaults to the V4 engine.

The generator uses 15 heuristics (priorities 1–11000) to derive C# type names from JSON Schema. Key ones:
title — uses the schema's title keyword$anchor / $id — uses the fragment or filename$ref path — derives from the $ref URI path/fragmentCollisions are resolved by appending a type-kind suffix: Object, Array, String, Number, Boolean.
Optional heuristics can be disabled via CorvusTextJsonDisabledNamingHeuristics.
For complex generation scenarios, use a config file (corvusjson config):
{
"typesToGenerate": [
{
"schemaFile": "schemas/main.json",
"rootTypeName": "MainType"
}
],
"additionalFiles": [
{ "canonicalUri": "https://example.com/shared.json", "contentPath": "schemas/shared.json" }
],

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add corvus-dotnet/Corvus.JsonSchema --skill corvus-codegen -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/corvus-codegen, .gemini/skills/corvus-codegen, .github/skills/corvus-codegen and .opencode/skills/corvus-codegen in your project.
Going by SKILL.md and its folder, Corvus Codegen needs the command-line tools its instructions call (dotnet).
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Corvus Codegen is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.1k tokens (SKILL.md is roughly 8.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
