<Summary type="rolling" window-days="90" release-count="11">
Stainless pushed toward deeper AI agent integration and expanded distribution capabilities. The skills command teaches coding agents how to use the CLI itself, while the docs platform entered public beta to centralize project documentation. On the SDK side, they shipped per-endpoint security codegen to fix authentication conflicts, PyPI trusted publishing via OIDC for Python packages, and CLI tools gained raw file download endpoints with smart output naming. The CLI generator itself graduated to general availability after the January launch.
</Summary>

<Summary type="monthly" period="March 2026" release-count="5">
March focused on extending Stainless across AI workflows, release distribution, and CLI capabilities. The skills command lets coding agents discover how to use the Stainless CLI by auto-detecting project structure and installing to the right agent directory. Separately, the Docs Platform entered public beta, while CLI tools gained file download endpoints with output control via flags or smart naming, and generated SDKs can now omit X-Stainless-* headers through config.

## Skills for the Stainless CLI

The new stl skills command installs a Stainless CLI skill into your project so coding agents like Claude Code, Codex, and Gemini can learn how to use the Stainless CLI. It auto-detects whether your project uses .agents/ or .claude/ and installs to the right location, with symlink support when both exist.

## CLI tool binary endpoint downloads

Generated CLI tools now support endpoints for downloading files using raw file data. The output destination can be specified with --output / -o flags, or if unspecified, a smart filename will be chosen to avoid overwriting local files. Files can also be sent through pipes or IO redirection.
