SWE Marketplace
A curated Claude Code plugin marketplace for practical, everyday usage in software engineering — 13 plugins, 53 specialist agents, 14 skills, 3 commands. A few opinionated choices that set it apart from larger awesome-style lists:
- Curated, not exhaustive. Every plugin and agent is one I actually use. No vendored grab-bags, no auto-generated stubs of skills the model already has.
- SDK-loadable. Every plugin ships both the catalog entry and a per-plugin
plugin.json, so consumers using the Claude Agent SDK (ClaudeAgentOptions.plugins=[{"type":"local","path":...}] or --plugin-dir) can load them directly. Many marketplaces only ship the catalog and silently fail to register skills/commands/hooks when loaded that way.
- CI-guarded drift. A GitHub Action validates manifest sync on every PR.
- Zero-warning validation. Every plugin passes
claude plugin validate with no errors or warnings.
= Most skills & plugins have been run through exhaustive evals. I am an avid fan of skill-creator and have a custom-build eval harness for building and evaluating plugins. Many of the resources here are fruit borne from that work.
Quick start
# In Claude Code
/plugin marketplace add https://github.com/andisab/swe-marketplace.git
/plugin install context-engineering@swe-marketplace
# Restart Claude Code, then verify with /help or /agents
Browse the full catalog with /plugin marketplace list. Every plugin is claude plugin validate-clean and version-pinned in marketplace.json.
What's inside
adv — Adversarial multi-model code review (v0.2.0)
Cross-examines code changes using Claude, Codex CLI, and Gemini CLI together. One agent orchestrates 5 specialized reviewers; three commands let you talk to each model directly.
- Agent:
adv-review
- Skill:
dispatch (shared multi-model CLI infrastructure)
- Commands:
/adv-codex, /adv-gemini, /adv-gemini-research
context-engineering — The plugin you use to build other plugins (v1.1.0)
End-to-end toolkit for authoring Claude Code resources following Anthropic specs. Templates, examples, and discovery-optimized patterns for every component type.
- Agent:
context-engineer
- Skills:
agent-dev, skill-dev, command-dev, hook-dev, plugin-dev, mcp-tool-dev, mcp-server-dev
research-team — Multi-agent research orchestration (v1.2.3)
A coordinator skill decomposes a topic into subtopics, spawns parallel research-specialist subagents, then hands off to a research-report-writer for synthesis. Joplin output supported.
- Agents:
research-specialist, research-report-writer
- Skills:
coordinator, joplin-research
knowledgeware — Style-driven deliverable suite (v1.1.1)
Four skills that share one brandbook format and a central style registry: slideware (two output formats — PowerPoint via pptxgenjs or single-file HTML via Reveal.js; asks which when the request doesn't say), knowledgebase (multi-page HTML knowledge bases), chartware (draw.io architecture diagrams), and brandware (registry manager — import, website derivation, per-brand logo-asset folders, local Google Fonts installation, chart-styling guidelines). Ships 5 generic styles plus a fictional acmecorp example brand showing the brand-folder layout; real brandbooks live in a private overlay (styles/brands/, gitignored) so proprietary identities never enter the public repo.
- Skills:
slideware, knowledgebase, chartware, brandware

Plugin manifests
Two manifests ship together:
.claude-plugin/marketplace.json (repo root) — catalog used by /plugin marketplace add and /plugin install. Source of truth.plugins/<name>/.claude-plugin/plugin.json — per-plugin manifest used by SDK consumers loading plugins directly. Generated from the matching marketplace.json entry.
python scripts/synthesize-plugin-manifests.py # regenerate
python scripts/synthesize-plugin-manifests.py --check # drift check (CI runs this)
./scripts/validate-all.sh # full validation
