Project Reactor skills for reactive programming with Flux, Mono, operators, schedulers, sinks, and reactor-test.
Author Reactor pipelines with Flux and Mono. Use this skill when designing or reviewing Flux/Mono source creation, operator composition, combination, empty/error behavior, ordinary backpressure choices, and everyday Context usage in Project Reactor.
Design Reactor execution context with explicit scheduler choice, publishOn/subscribeOn placement, and blocking-boundary decisions. Use this skill when designing or reviewing Reactor execution context decisions: scheduler choice, publishOn/subscribeOn placement, blocking offload, thread-affinity boundaries, and ordinary scheduling diagnostics.
Author Reactor hot sources with Sinks for manual emission, replay/multicast selection, and emit-result handling. Use this skill when designing or reviewing Reactor hot-source APIs with Sinks: sink type selection, manual emission, replay/multicast choices, emit result handling, and the boundary between Sinks and ConnectableFlux-style sharing.
Test Reactor publishers with reactor-test using StepVerifier, virtual time, TestPublisher, and PublisherProbe. Use this skill when designing or reviewing Reactor tests with reactor-test: StepVerifier workflow, virtual time, request and cancellation assertions, TestPublisher, PublisherProbe, and ordinary post-verification checks.

Sinon is a universal AI plugin marketplace repository.
This repository uses the official marketplace paths for Claude Code and Codex, with plugins stored under plugins/.
README.md: repository overview and contribution context..gitignore: development ignore rules..markdownlint.jsonc: Markdown lint configuration..claude-plugin/marketplace.json: Claude marketplace catalog..agents/plugins/marketplace.json: Codex marketplace catalog.plugins/: plugins maintained in this repository.Plugins are stored under plugins/.
Each plugin directory can expose one or more runtime manifests from the same plugin root.
.claude-plugin/plugin.json: Claude plugin manifest..codex-plugin/plugin.json: Codex plugin manifest.
Optional plugin assets such as README.md, .mcp.json, .app.json, commands/, agents/, skills/, and assets/ live beside those manifests at the plugin root.The repository keeps separate official marketplace catalogs per runtime.
This list describes the plugins currently published through the repository marketplace catalogs.

.agents/plugins/marketplace.json is the Codex marketplace catalog.
Individual plugin directories remain the source of truth for plugin-specific runtime manifests and bundled assets.
Bundled upstream plugins may support only a subset of runtimes. In some cases, this repository may add minimal runtime metadata such as .codex-plugin/ while leaving the upstream plugin content otherwise intact.
Claude Code supports registering marketplaces from GitHub repositories, generic git URLs, direct URLs to marketplace.json, and local paths.
For this repository, use a GitHub repository, git URL, or local path. Sinon currently uses relative plugin sources such as ./plugins/java inside .claude-plugin/marketplace.json, so a direct HTTP URL to the catalog file is not a safe distribution path for this marketplace.
The Claude marketplace catalog for this repository is:
.claude-plugin/marketplace.jsonRegister this marketplace from a local checkout:
/plugin marketplace add /path/to/sinon
Register this marketplace from GitHub:
/plugin marketplace add ririnto/sinon
Register this marketplace from a generic git URL:
/plugin marketplace add https://github.com/ririnto/sinon.git
After Claude Code registers the sinon marketplace, install a plugin from it with:
/plugin install <plugin>@sinon
Examples:
Kotlin development plugin with practical skills for idiomatic language design, coroutines and Flow decisions, Kotlin testing workflows, and kotlin-lsp-assisted editing.
JVM development assistant with shared skills for tooling workflows, runtime diagnostics, and garbage-collection guidance.
