Dev & Coding

A meta-skill that turns a finished task, log trail, or refined workflow into a validated, reusable skill package.

Wires JSpecify, NullAway/ErrorProne and @NullMarked into a Java project so null bugs fail the build.

Clears pre-existing repo-wide lint warnings, type errors, and suppressions in safe waves — one rule at a time, tests green after each.

Empirically detects nondeterministic tests via repeat/shuffle/parallel runs, diagnoses the root cause, and fixes it without retries, sleeps, or skips.

Turns a plain-English project description into a progen CLI config and scaffolds a full production-ready Spring Boot project.

Collects every open Renovate pull request from a GitHub repo and applies their diffs to your local working tree so the combined dependency upgrade can be built and tested at once.

A convention skill for designing, implementing, and testing Cubits and Blocs with bloc/flutter_bloc in Flutter.

Gives Claude the reference map and coding rules needed to build Genkit AI flows, tools and agents in Dart or Flutter.

A skill for writing idiomatic Dart 3 pattern matching, records and sealed classes, and for migrating pre-Dart-3 code.

A step-by-step skill that diagnoses common Terraform/OpenTofu failure modes and proposes fixes with explicit risk controls.

Tracks new Claude Code releases and reports their impact on your plugin as breaking changes, opportunities, or deprecations.

An authoritative lookup skill for the Claude/Anthropic SDK covering model IDs, params, streaming, tool use, agents, caching, and model migration.

A lint skill that structurally validates Claude Code agent and skill markdown files — frontmatter, naming, and body rules — so misconfigured files don't fail silently at runtime.

Diffs HEAD against the latest published npm versions and reports every unpublished change per release layer, with semver bump recommendations.

Turns Claude into an orchestrator that delegates each phase of an implementation plan to specialized subagents and blocks commits until verification passes.

An architecture skill that audits your layers, boundaries and SOLID usage against the Dependency Rule and prescribes concrete inversions.

Commits the working tree as one commit per logical change, merges in upstream, resolves conflicts hunk by hunk, and pushes — never with force.

A staged playbook for publishing Python, R, and static content to a Posit Connect server with the correct commands and flags.

Generates INVENTORY-SKILLS-JAVA.md, a complete checklist of Java system-prompt skills derived from the Plinth repo's skills.xml.
