Breaking changes between two versions: npm, PyPI, GitHub Actions, Helm, Terraform, crates.io, Go.
Scored across 12 tools
Most tools are clearly separated by ecosystem and artifact type, so an agent can usually select the right one. The main ambiguity is between the per-ecosystem breaking_changes tools and the corresponding changelog tools, since both return release notes and extracted breaking items; dependency_upgrade_plan also overlaps with the single-package breaking-change tools, though its multi-package risk-ordering purpose helps distinguish it.
The tool set mostly follows a predictable ecosystem_artifact/action pattern such as npm_breaking_changes, pypi_changelog, and terraform_breaking_changes. Minor deviations include dependency_upgrade_plan not using an ecosystem prefix and singular/plural inconsistencies like github_action_breaking_changes versus crates_breaking_changes, but the names remain readable and consistent overall.
Twelve tools is a well-scoped size for a multi-ecosystem upgrade-brief server. Each ecosystem-specific breaking-change tool covers a distinct artifact type, and the additional versions, changelog, and multi-package plan tools earn their place without excessive proliferation.
The surface covers breaking-change briefs for several ecosystems and provides full version/changelog support for npm and PyPI, but coverage is uneven. Crates, Go, Helm, Terraform, and GitHub Actions lack companion versions or changelog tools, forcing agents to supply valid from/to versions externally and creating version-discovery dead ends for those ecosystems.
Rust crate upgrade brief between two versions: removed and changed Cargo features, default feature changes, dependency requirement diff, rust-version (MSRV) and edition changes, yanked releases in the range, breaking items from GitHub releases and CHANGELOG, the Cargo.toml edit.

Inputs: packages (required), ecosystem.
GitHub Actions upgrade brief between two versions of an action (e.g. actions/checkout v3 to v4): breaking changes from release notes and migration docs, action.yml input/output diff (removed, renamed, new required inputs, changed defaults), Node runtime change (node16/node20 removed, node24), deprecations, concrete workflow edits with SHA pin, and sources. Paid: $0.005 USDC per call via x402.
Inputs: from (required), action (required), to, with, +1 more.
Go module upgrade brief between two versions: go.mod diff (go directive, requirements), major /vN import path change with the rewrite command, retracted and deprecated flags, breaking items from GitHub releases and CHANGELOG, the go get command. Paid: $0.005 USDC per call via x402.
Inputs: from (required), module (required), to, prereleases.
Helm chart upgrade brief between two chart versions: default values.yaml diff (removed, added, changed keys and possible renames), chart changelog and breaking items from Artifact Hub and the chart repo, README upgrade sections, kubeVersion, subchart and appVersion changes, concrete edits for your values file, sources. Paid: $0.01 USDC per call via x402.
Inputs: from (required), chart (required), to, values, +1 more.
npm breaking changes between two versions of a package, read from its real CHANGELOG and GitHub release notes: documented breaking items per version, major bumps, Node.js engine / ESM-CJS / peer dependency changes, migration guide links and a verdict. Paid: $0.005 USDC per call via x402.
Inputs: from (required), package (required), to, prereleases.
