Measured tools (7)

• check_dependencies read-only

  Check a dependency manifest (package.json, requirements.txt, pyproject.toml or Pipfile) for third-party API SDKs that are major versions behind, deprecated or replaced, against the live npm registry and PyPI. Returns each SDK's current spec, latest version, release-notes link and a Versyka migration guide when one exists.

  Parameters:

  • manifest (required) — string — The full text of the manifest file.
  • all — boolean — Check every package, not just third-party API SDKs.
  • file_name — string — The file name, e.g. requirements.txt. Helps detect the format.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• find_retired_models read-only

  Scan source and config files for AI model IDs that the vendor (OpenAI, Anthropic, Google Gemini, Mistral, Cohere) or hosting platform (Amazon Bedrock, Groq) has retired or scheduled for retirement. Exact matches only, including Bedrock, Vertex AI, LiteLLM and OpenRouter spellings. Returns each model's shutdown date, days left, the vendor's recommended replacement, the source page and the file:line locations.

  Parameters:

  • files (required) — array — Files to scan, each with its repository-relative path and full text.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• lookup_model read-only

  Is this AI model ID retired or scheduled for retirement? Accepts plain IDs and gateway spellings (e.g. openai/gpt-4-0613, anthropic.claude-3-sonnet-20240229-v1:0, claude-3-opus@20240229). Returns the shutdown date, status, replacement and source, or that no retirement is listed.

  Parameters:

  • model (required) — string — The model ID as written in code or config.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• list_model_retirements read-only

  The AI model retirement calendar: model IDs with their shutdown dates, replacements and sources, soonest first. Filter by vendor or by how many days ahead to look.

  Parameters:

  • vendor — string
  • within_days — integer — Only retirements within this many days from today.
  • include_retired — boolean — Also list models that are already retired.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_sdk_versions read-only

  The latest version of an npm or PyPI package, whether it is deprecated, its release-notes link, the API vendor it belongs to and a Versyka migration guide when one exists.

  Parameters:

  • package (required) — string — Package name, e.g. openai, @anthropic-ai/sdk, boto3.
  • ecosystem (required) — string — Which registry: npm (JavaScript/TypeScript) or pypi (Python).

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• list_migration_guides read-only

  Versyka's step-by-step SDK migration guides (OpenAI, Anthropic, Google Gemini, AWS, Stripe, Firebase, Slack, Twilio, Auth0, Pinecone), optionally filtered by package name.

  Parameters:

  • package — string — Only guides for this package, e.g. openai.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_migration_guide read-only

  One migration guide as Markdown: what changed, each step with before and after code, how to find every affected call, how to test, and the vendor sources it is based on.

  Parameters:

  • slug (required) — string — The guide slug from list_migration_guides, e.g. openai-python-v0-to-v1.
