librel Skill

When to Use

• Bumping package versions (major/minor/patch)
• Detecting which packages changed between commits
• Retrieving CloudFormation outputs for deployment
• Automating release workflows

Key Concepts

VersionBumper: Updates package.json version following semver rules.

ChangeDetector: Compares git refs to identify modified packages.

StackQuery: Retrieves AWS CloudFormation stack outputs for deployment config.

Usage Patterns

Pattern 1: Bump version

import { VersionBumper } from "@copilot-ld/librel";

const bumper = new VersionBumper("./packages/libagent");
await bumper.bump("minor"); // 1.0.0 -> 1.1.0

Pattern 2: Detect changes

import { ChangeDetector } from "@copilot-ld/librel";

const detector = new ChangeDetector(".");
const changed = await detector.getChangedPackages("main", "HEAD");
// ["libagent", "libmemory"]

Integration

Used by CI/CD scripts for release automation and change detection.
