Measured tools (31)

• check_before_install

  Call this before adding a dependency. Returns only the facts a reviewer would be annoyed to discover afterwards: whether the publisher has withdrawn the package, whether it runs scripts on the installing machine, whether its repository is archived, how many advisories are on record, whether the licence is source-available, and how long since it was actually published. Each fact carries the address of the body that published it. It does not say whether to install; it says what is on record.

  Parameters:

  • registry (required) — string
  • name (required) — string — Package name as the registry spells it.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• check_package

  Read the current standing of one open-source package: downloads with the window they cover, OpenSSF scorecard, advisory count, licence, whether the repository is archived, and when it was last pushed to.

  Parameters:

  • registry (required) — string
  • name (required) — string — Package name as the registry spells it.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• check_stack

  Read a whole dependency list at once and report what is archived, what carries advisories, what has a source-available licence, and what has not been pushed to in a year. Use when reviewing a package.json, requirements.txt, Cargo.toml, composer.json or Gemfile.

  Parameters:

  • registry (required) — string
  • names (required) — array

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• search_repositories

  Find watched repositories whose name contains a string, with their current readings. Use it to discover what is covered before calling the other tools.

  Parameters:

  • query (required) — string
  • limit — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• compare_repositories

  Hold two watched repositories against each other across downloads, OpenSSF scorecard, advisories, forks, stars and findings on record. Compares only; it does not pick a winner.

  Parameters:

  • a (required) — string — Repository as owner/name.
  • b (required) — string — Repository as owner/name.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• find_model

  Find language models by price and context window, from a catalogue read daily across sixty providers. Use this before choosing a model: prices move without announcement and training data is out of date on the day it ships.

  Parameters:

  • maxPrice — number — Maximum USD per million prompt tokens.
  • provider — string
  • minContext — integer — Minimum context window in tokens.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• check_eol

  Check whether a runtime, database or framework release is still receiving security fixes, and what to move to. Covers about two dozen products read daily from endoflife.date.

  Parameters:

  • product (required) — string — Product as endoflife.date spells it, e.g. python, nodejs, postgresql.
  • cycle — string — Release line, e.g. 3.9 or 20. Omit for every cycle.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• check_provider

  Recorded incidents for a hosting or API provider over a window, kept after the provider’s own status page dropped them.

  Parameters:

  • days — integer
  • provider — string — Provider slug, e.g. cloudflare, openai, github. Omit for every provider.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
