Add new developer-essentials plugin containing 8 high-value skills that
address critical gaps in the existing skill coverage:
Skills Added:
- git-advanced-workflows: Advanced Git techniques (rebase, cherry-pick, bisect, worktrees, reflog)
- sql-optimization-patterns: SQL query optimization, indexing, and EXPLAIN analysis
- error-handling-patterns: Multi-language error handling strategies and patterns
- code-review-excellence: Effective code review practices and constructive feedback
- e2e-testing-patterns: End-to-end testing with Playwright and Cypress
- auth-implementation-patterns: Authentication/authorization with JWT, OAuth2, RBAC
- debugging-strategies: Systematic debugging techniques and profiling tools
- monorepo-management: Monorepo setup and management with Turborepo, Nx, pnpm
These skills were identified through comprehensive research of:
- Existing 50+ skills across 14 plugins in the project
- Anthropic's official skills repository
- Gap analysis revealing missing coverage in general developer workflows
Changes:
- Added plugins/developer-essentials/ with 8 new SKILL.md files
- Updated .claude-plugin/marketplace.json to register new plugin
- Updated docs/agent-skills.md (47→55 skills, 14→15 plugins)
Each skill follows Anthropic's Agent Skills Specification with proper
YAML frontmatter, progressive disclosure, and clear activation triggers.

Fantastic work, Ryan! You delivered an exceptional shell-scripting plugin with comprehensive coverage of defensive programming, static analysis, and testing patterns. Your responsiveness to feedback and commitment to quality are exactly what we value in this project. Thanks for the great contribution! 🎉
- Migrate all 48 Opus agents to Sonnet
- Optimize 35 execution-focused agents for Haiku
- Update README with hybrid orchestration patterns
- Simplify model configuration to use agnostic aliases
Final distribution: 97 Sonnet / 47 Haiku agents
- Revert plugin name from embedded-systems to arm-cortex-microcontrollers
- Keep original name chosen by contributor Ryan Snodgrass
- Update all references in README.md and marketplace.json
- Plugin structure remains properly organized in plugins/ directory
- Refactor standalone agent into proper plugin structure
- Create plugins/embedded-systems/ directory with agents/ subdirectory
- Move arm-cortex-expert.md to plugins/embedded-systems/agents/
- Update marketplace.json plugin name and source path
- Update README.md to reflect 7 language plugins (was 6)
- Add embedded-systems to Languages plugin table
- Update all agent references to new path
- Remove empty agents/ directory
This aligns the embedded-systems plugin with the standard plugin
architecture used throughout the repository.
- Organize 62 plugins into isolated directories under plugins/
- Consolidate tools and workflows into commands/ following Anthropic conventions
- Update marketplace.json with isolated source paths for each plugin
- Revise README to reflect plugin-based structure and token efficiency
- Remove shared resource directories (agents/, tools/, workflows/)
Each plugin now contains only its specific agents and commands, enabling
granular installation and minimal token usage. Installing a single plugin
loads only its resources rather than the entire marketplace.
Structure: plugins/{plugin-name}/{agents/,commands/}
