What it does

Spikard is an agent skill from Goldziher/spikard. Scaffold Spikard projects and generate code from OpenAPI, AsyncAPI, OpenRPC, GraphQL, and Protobuf schemas using the Spikard CLI or its MCP server. Use when building or updating Spikard-based apps, fixtures, test apps, or agent workflows that should prefer code generation over handwritten boilerplate.

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `references/cli-reference.md`, `references/codegen-workflows.md` and `references/language-bindings.md`).

It sits in Backend & APIs, covering Project scaffolding, gRPC and Protobuf and OpenAPI specifications. It works with Model Context Protocol, gRPC, OpenAPI and GraphQL. The repository describes itself as: Codegen-first polyglot web toolkit: one Rust core, 14 language bindings, spec-driven codegen (OpenAPI, AsyncAPI, GraphQL, gRPC, SQL to HTTP) and a 13-tool MCP server… The licence is MIT.

When your agent uses it

  • Updating Spikard-based apps
  • Agent workflows that should prefer code generation over handwritten boilerplate

Example prompts

  • “/spikard”

What it can do on your machine

Read from SKILL.md and the folder at commit 13216c1. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    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

Spikard loads about 799 tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 78 tokens; SKILL.md has 282 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~799
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

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.

Spikard Codegen-First Workflows

Spikard is a Rust-centric framework with polyglot bindings and a codegen-first CLI. For agent workflows, prefer the MCP server because it exposes the same scaffolding, generation, validation, and fixture flows as structured tools instead of shell output.

Use this skill when the task involves:

  • Scaffolding a new Spikard project
  • Generating handlers or types from API schemas
  • Building AsyncAPI fixtures or language-specific test apps
  • Validating AsyncAPI schemas before generation
  • Driving Spikard from an agent through MCP instead of shelling out repeatedly

Use MCP First

Start the tracked MCP server from the repo or installed binary:

bash
spikard mcp

Default transport is stdio. HTTP transport exists behind the mcp-http Cargo feature and is not the default workflow.

Use the MCP tools for:

  • init_project
  • generate_openapi
  • generate_asyncapi_handlers
  • generate_jsonrpc
  • generate_graphql
  • generate_protobuf
  • generate_php_dto
  • generate_asyncapi_fixtures
  • generate_asyncapi_test_app
  • generate_asyncapi_bundle
  • validate_asyncapi
  • get_features

Read references/mcp-tools.md when you need parameter details or defaults.

CLI Fallback

If MCP is unavailable, use the CLI directly. The CLI and MCP are backed by the same typed application layer in crates/spikard-cli/src/app.rs, so behavior should match.

Read:

Working Style

  • Prefer generated scaffolding over handwritten boilerplate.
  • Validate schemas before broad generation when the source spec may be invalid.
  • For AsyncAPI work, keep fixtures and generated test apps in sync.
  • Treat bindings as thin adapters over the Rust core; do not duplicate framework logic per language.
  • When touching generator behavior, run real CLI or library tests rather than only snapshotting text.

To copy it by hand, put the folder in .cursor/skills/spikard, .gemini/skills/spikard, .github/skills/spikard and .opencode/skills/spikard in your project.

What does Spikard need to run?

SKILL.md names no scripts, command-line tools or credentials: Spikard is instructions for the agent only.

Does Spikard access the network?

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.

Is Spikard safe to install?
