codegen

codegen is a skill for Claude Code, Codex from Azure/azure-sdk-for-java. It costs 37 tokens per session (660 once invoked), scanned A, original, MIT.

A workflow for generating code from TypeSpec, a language for describing APIs and their data types. It uses a project file named tsp-location.yaml to locate the TypeSpec inputs and tools.

In plain words
What is it for?
Use it to update code-generation tooling, sync TypeSpec definitions, generate code, optionally save the synced inputs, or change the recorded source commit before generation.
Why use it?
It gives a defined process for updating the generator, synchronizing TypeSpec sources, and producing code from them. This avoids running the workflow in a directory that lacks the required project file.

About the project

Azure SDK for Java is a collection of Java libraries that let applications connect to and manage Azure services. Java developers use its client libraries to consume services and its management libraries to configure Azure resources. The catalogue add-ons support development with these libraries.

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

codegen 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.

TypeSpec Code Generation (tsp-client)

Use this skill to run tsp-client workflows for projects that include a tsp-location.yaml file.

Preconditions

  • You must be in the directory that contains tsp-location.yaml.
  • If the file is missing, warn the user and ask for the correct directory (do not run commands).

Commit hash update

If the user provides a commit hash, update the commit: field in tsp-location.yaml before running tsp-client.

  • Read the file and locate the commit: line.
  • Replace the value with the provided hash (keep the same key name and formatting).
  • Example:
    • Before: commit: 6267b6...
    • After: commit: <new_hash>

Commands

tsp-client update

Pull the latest codegen tooling or definitions (default action when the user is vague).

tsp-client update

tsp-client sync

Fetch/sync TypeSpec inputs for the project.

tsp-client sync

tsp-client generate

Generate code from TypeSpec inputs.

tsp-client generate

Keep the synced TypeSpec inputs:

tsp-client generate --save-inputs

Steps

  1. Verify tsp-location.yaml exists in the current directory. If not, stop and ask for the correct location.
  2. If the user provided a commit hash, update the commit: value in tsp-location.yaml.
  3. Determine the user intent:
    • Refresh/update/ingest changes from a commit: run tsp-client update.
    • Fetch/sync spec from the current commit: run tsp-client sync.
    • Generate from fetched spec: run tsp-client generate (use --save-inputs only if the user asks to keep inputs).
    • Generate (no fetch requested): run tsp-client generate.
  4. If the user doesn’t specify, default to tsp-client update.
  5. If the project defines or creates a TempTypeSpecFiles folder and the user wants code generation, run tsp-client generate (with --save-inputs if requested).
  6. If a tsp-client command fails, report the error output and suggest checking the TypeSpec repo/commit referenced in tsp-location.yaml. Build a GitHub URL from repo: and directory: (and include the commit: as the ref), e.g.:
    • Repo: Azure/azure-rest-api-specs
    • Commit: 6267b6...
    • Directory: specification/cognitiveservices/OpenAI.Inference
    • URL: https://github.com/Azure/azure-rest-api-specs/tree/6267b6.../specification/cognitiveservices/OpenAI.Inference

codegen is a skill published in the GitHub repository Azure/azure-sdk-for-java (2,564 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 660 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
