corvus-yamlConvert between YAML 1.2 and JSON using the high-performance ref struct tokenizer.
Corvus YAML is an agent skill from corvus-dotnet/Corvus.JsonSchema. Convert between YAML 1.2 and JSON using the high-performance ref struct tokenizer. Covers the two packages (Corvus.Text.Json.Yaml for full integration, Corvus.Yaml.SystemTextJson for System.Text.Json-only), YAML→JSON and JSON→YAML conversion, schema modes, anchor/alias support, multi-document streams, Utf8YamlWriter, and 100% yaml-test-suite JSON-testable conformance (373 of 402 tests). USE FOR: YAML-to-JSON conversion, JSON-to-YAML conversion, understanding the tokenizer architecture, troubleshooting YAML…
Its SKILL.md is about 1.2k 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 Testing & QA, covering Test generation. The repository describes itself as: Support for Json Schema validation and entity generation. The licence is Apache-2.0.
Read from SKILL.md and the folder at commit b9e3040. 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 YAML loads about 1.2k tokens when it runs. Until then it costs about 150 tokens; SKILL.md has 337 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.

.claude/skills/corvus-yaml/SKILL.md (or your agent's skills folder).Conformance: 100% of JSON-testable cases — 373 of 402 total (279 valid + 94 error). The remaining 29 cases exercise YAML features with no JSON equivalent.
The YAML converter operates as a zero-allocation ref struct tokenizer on UTF-8 bytes, streaming tokens directly into a Utf8JsonWriter.
| Package | Purpose |
|---|---|
Corvus.Text.Json.Yaml | Full Corvus integration — returns ParsedJsonDocument<T> |
Corvus.Yaml.SystemTextJson | System.Text.Json only — writes to Utf8JsonWriter |
// Full Corvus integration — returns ParsedJsonDocument<T>
using ParsedJsonDocument<JsonElement> doc = YamlDocument.Parse<JsonElement>(yamlBytes);
JsonElement root = doc.RootElement;
// System.Text.Json only — returns JsonDocument
JsonDocument doc = YamlDocument.Parse(yamlBytes);
// Get JSON string from YAML
string json = YamlDocument.ConvertToJsonString(yamlBytes);// Convert a JSON element to a YAML string (static method on YamlDocument)
string yaml = YamlDocument.ConvertToYamlString(jsonElement);
// Convert to YAML, writing to an IBufferWriter<byte>
YamlDocument.ConvertToYaml(jsonElement, bufferWriter);
// Convert to YAML, writing to a Stream
YamlDocument.ConvertToYaml(jsonElement, utf8Stream);KYAML (Kubernetes KEP-5295) is a strict subset of YAML 1.2: explicit { } / [ ]
delimiters laid out across indented lines, string values always double-quoted, numbers/
booleans/null bare, keys quoted only when ambiguous, trailing comma after every element.
Output is always valid YAML 1.2 (read it back with YamlDocument.Parse, no config needed).
Enable it on any ConvertToYaml* overload (or Utf8YamlWriter) via the options:
// Preset (easiest):
string kyaml = YamlDocument.ConvertToYamlString(json, YamlWriterOptions.Kyaml);
// Or set the format explicitly:
var options = new YamlWriterOptions { Format = YamlWriterFormat.Kyaml };Implemented entirely in Utf8YamlWriter (gated on YamlWriterFormat.Kyaml); the JSON→YAML
converter is format-agnostic. Output is canonical (non-"cuddled") KYAML.
Four YAML schema modes control how scalar values are interpreted:
| Mode | Description |
|---|---|
| Core | YAML 1.2 Core Schema (default) |
| JSON | JSON-compatible — strings, numbers, booleans, null only |
| Failsafe | All scalars as strings |
| Yaml11 | YAML 1.1 compatibility (yes/no/on/off booleans, sexagesimal integers, merge keys) |

Run `npx skills add corvus-dotnet/Corvus.JsonSchema --skill corvus-yaml -a claude-code`. Or copy the skill folder (.github/skills/corvus-yaml in corvus-dotnet/Corvus.JsonSchema) into .claude/skills/corvus-yaml in your project. Claude Code loads it when a task matches its description.
Run `npx skills add corvus-dotnet/Corvus.JsonSchema --skill corvus-yaml -a codex`. Or copy the skill folder (.github/skills/corvus-yaml in corvus-dotnet/Corvus.JsonSchema) into .agents/skills/corvus-yaml in your project. Codex loads it when a task matches its description.
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-yaml -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-yaml, .gemini/skills/corvus-yaml, .github/skills/corvus-yaml and .opencode/skills/corvus-yaml in your project.
Going by SKILL.md and its folder, Corvus YAML 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 YAML 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 1.2k tokens (SKILL.md is roughly 4.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
