Pulled straight from the server with tools/list on 2026-10-17.
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 Returns only the facts a reviewer would be annoyed to discover afterwards: whether the publisher has withdrawn the package, whether it runs scripts on the installing machine, whether its repository is archived, how many advisories are on record, whether the licence is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

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.

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.

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.

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.

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 Use this before choosing a model: prices move without announcement and training data is out of date on the day it ships.

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.

check_provider

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

list_readings

List every reading this server can return, what each one measures, and which require a key. Call this first if unsure which tool answers a question.

who_can_publish

How many accounts hold publish rights on a package, as the registry lists them. Answers who can put code on your machine, which is a different question from who writes it. Requires a key; see https://sighttrue.com/pricing.

package_weight_history

How the published artefact size has moved over time. Returns the readings taken, not a verdict. Requires a key; see https://sighttrue.com/pricing.

withdrawn_but_installed

Packages whose own publisher has withdrawn them and which are still being installed heavily, with the download figure and the publisher’s notice. Requires a key; see https://sighttrue.com/pricing.

typosquat_check

Whether a name is one edit away from a more widely installed package. States that both names exist; which one was meant is the caller’s call. Requires a key; see https://sighttrue.com/pricing.

funding_gap

Packages that ask for funding, beside how heavily they are installed and how many people write them. Requires a key; see https://sighttrue.com/pricing.

time_to_fix

Days between an advisory being published and a release appearing that postdates it, per package and as a distribution. Requires a key; see https://sighttrue.com/pricing.

advisory_severity

Advisories broken down by severity rather than counted, with identifiers and dates. Requires a key; see https://sighttrue.com/pricing.

runtime_deadlines

Support end dates for the runtimes a dependency set requires, including any already past. Requires a key; see https://sighttrue.com/pricing.

base_image_check

For a container base image: its size, when it was last rebuilt, and whether the OS underneath it is still supported. Requires a key; see https://sighttrue.com/pricing.

registry_health

Recorded outages of the package registries themselves, kept after their status pages drop them. Requires a key; see https://sighttrue.com/pricing.

provider_incidents

A provider’s recorded incidents, grouped by the component that failed, over the whole archive rather than the window its status page shows. Requires a key; see https://sighttrue.com/pricing.

provider_transparency

How long a provider takes to acknowledge an incident: the interval between an incident starting and its first public update. Requires a key; see https://sighttrue.com/pricing.

provider_terms_changed

When a provider last changed its terms or pricing page, from a stored fingerprint of the page. Requires a key; see https://sighttrue.com/pricing.

model_price_history

Every recorded price for a model, with the date each was read. Requires a key; see https://sighttrue.com/pricing.

model_withdrawn

Models that were in the catalogue and no longer are, with the date last seen. Requires a key; see https://sighttrue.com/pricing.

help_availability

For a technology tag: questions asked against questions answered, over time. Requires a key; see https://sighttrue.com/pricing.

audit_manifest

Read a whole manifest and return every reading on record for it, ordered by how much a reviewer would want to know. One call instead of one per dependency. Requires a key; see https://sighttrue.com/pricing.

diff_since

What changed for a set of packages since a given date, read from the daily archive. Requires a key; see https://sighttrue.com/pricing.

watch_add

Add a package to the caller’s own private watchlist, so later readings are about their stack rather than the public one. The list is private to the key that created it. Requires a key; see https://sighttrue.com/pricing.

watch_changes

Everything that has changed across the caller’s private watchlist since a given date: withdrawals, licence changes, advisories, archived repositories and runtimes going out of support. Requires a key; see https://sighttrue.com/pricing.

explain_finding

Given a finding id, return what was measured, when, by whom, and the address it can be checked at. For an agent quoting a figure into a review. Requires a key; see https://sighttrue.com/pricing.

domain_risk

Whether the domains a package points at — homepage, funding, documentation — still resolve to a registered owner. Requires a key; see https://sighttrue.com/pricing.
