tagpr is a Go CLI tool that automates the GitHub release workflow. It runs as a GitHub Action, monitoring the main branch. When unreleased changes exist, it creates or updates a release pull request with an auto-generated changelog. When that PR is merged, tagpr automatically tags the merge commit with the next semantic or calendar version and creates a GitHub Release. It supports monorepo configurations via tag prefixes, custom version files, label-based version bumping, and both SemVer and CalVer schemes. The tool integrates deeply with the GitHub API (PRs, releases, git trees, issues) and local git commands. It also includes a reusable submodule `gh2changelog` for generating changelogs from GitHub release notes. The codebase is well-structured, with clear separation of concerns, extensive tests, and a functional options pattern for configuration.

ecschedule is a production-grade CLI tool for managing AWS EventBridge scheduled tasks that trigger ECS tasks. Written in Go, it uses declarative YAML/JSON/Jsonnet configuration files with template functions for environment variables, tfstate lookups, and SSM parameters. The tool supports full lifecycle management: dumping existing rules, diffing local vs remote state, applying changes (create/update/delete), and manually triggering rules. It provides parallel execution for performance, unified diff output with color control, and a plugin system for tfstate and ssm integrations. The codebase demonstrates strong engineering practices: clean separation of concerns, comprehensive unit tests, CI/CD pipelines, and dependency management with dependabot. The architecture is a single-binary CLI with subcommands, leveraging AWS SDK v2 and a custom template engine that defers variable resolution for idempotent diffing. Notable design patterns include a generic parallel job executor with panic recovery and context cancellation, a 'localYAMLForDiff' normalization technique to avoid flapping diffs, and a Resource Groups search-based orphan rule detection using custom tags.
