SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

kit prevents “version drift” and weak supply-chain verification when installing developer tools from multiple git-based registries by making resolution, integrity checks, and trust posture explicit and reproducible.

Core Features & Use Cases

Resolve cross-registry tool versions: selects the effective tool definition across configured registries and generates the corresponding mise configuration lock.
Enforce verification posture by tier: validates installed binaries using the required method (cosign/attestation for higher trust tiers, checksums for lower tiers) rather than relying on ad-hoc installs.
Automate upstream update tracking (CI pipelines): supports a three-stage workflow to detect upstream changes, evaluate them, apply updates, and hard-gate registry merges via deterministic verification.

Quick Start

Run the safety-first flow by syncing your resolved tool versions with kit sync after you set up one registry, then confirm what you actually have with kit status.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I prevent version drift when installing developer tools from multiple git-based registries?▼

You prevent version drift by resolving cross-registry tool definitions and generating a locked mise configuration, ensuring your installed environment stays synchronized with the declared registry state.

How does cosign signature verification work for developer toolchain binaries?▼

Cosign signature verification for developer toolchain binaries works by enforcing a tier-based trust posture, validating higher-trust tier binaries through cosign attestations rather than relying on ad-hoc checksums or unverified installs.

What is the best way to automate upstream update tracking for developer toolchains in CI pipelines?▼

The best way to automate upstream update tracking in CI pipelines is using a deterministic three-stage workflow that detects upstream changes, evaluates them, applies updates, and hard-gates registry merges via required verification checks.

Does kit support local pin overrides for specific developer tool versions?▼

Yes, the tool supports local pin overrides, allowing developers to explicitly set and maintain specific tool versions locally while still tracking upstream registry changes and enforcing required checksum or signature verification.

Can I use checksum verification instead of cosign for lower trust tier developer tools?▼

Yes, you can use standard checksum verification instead of cosign for lower trust tier developer tools, as the system enforces verification posture by tier to apply the appropriate integrity checks based on your configured trust levels.

How do I sync resolved developer tool versions and check my current verification status?▼

You sync resolved developer tool versions by running the safety-first flow with a sync command after setting up a registry, then check your current installed versions and verification posture using a status command.
