Core agents, commands, skills, and hooks required by all Developer Kit plugins.
The developer-kit plugin (directory: developer-kit-core/) provides the foundational components shared across all Developer Kit plugins. This plugin is required by all other plugins in the Developer Kit marketplace.
Backward Compatibility Note: The plugin name in the manifest is
developer-kit(notdeveloper-kit-core) to maintain compatibility with the existingdevkit.*command prefixes. The directory is nameddeveloper-kit-corefor structural clarity.
| Component Type | Count | Description |
|---|---|---|
| Agents | 7 | General-purpose AI assistants for code analysis, review, refactoring, architecture, debugging, documentation, and pattern learning |
| Commands | 16 | Reusable workflows for feature development, refactoring, debugging, documentation, GitHub integration, and long-running agent sessions |
| Skills | 6 | Specialized capabilities for ADR drafting, memory management, documentation updates, draw.io diagrams, GitHub issues, and project pattern learning |
| Hooks | 1 | Security hook that prevents destructive Bash commands |
Agents are specialized AI assistants with dedicated contexts, custom prompts, and specific tool access. Invoke them using the Agent tool with subagent_type.
| Agent | Purpose | When to Use |
|---|---|---|
general-code-explorer | Deep codebase analysis | Tracing execution paths, mapping architecture layers, understanding how features are implemented |
general-code-reviewer | Code review | Reviewing code changes for quality, bugs, logic errors, security, and best practices (reports only issues with confidence >= 80%) |
general-refactor-expert | Code refactoring | Improving code quality and maintainability while preserving functionality (SOLID patterns, clean code principles) |
general-software-architect | Architecture design | Planning new features, designing system architecture, creating implementation blueprints |
general-debugger | Debugging | Root cause analysis, tracing execution paths, identifying failure points, proposing targeted fixes |
document-generator-expert | Documentation | Creating professional technical and business documents (assessments, specs, reports, process docs) |
learn-analyst | Pattern extraction | Extracting development patterns and conventions from codebase analysis for the learn skill |
Agent(
subagent_type="general-code-explorer",
prompt="Trace the user authentication flow in this codebase"
)Commands are reusable workflows invoked with /developer-kit:devkit.<command-name>. They guide Claude through specific procedures with mandatory confirmation gates.
| Command | Purpose | Arguments |
|---|---|---|
devkit.feature-development | Guided feature implementation | [--lang=...] [feature-description] |
devkit.refactor | Guided code refactoring | [--lang=...] [--scope=...] [refactor-description] |
devkit.fix-debugging | Guided bug fixing | [--lang=...] [issue-description] |
devkit.verify-skill | Validate skill against DevKit standards | [skill-name] |
| Command | Purpose |
|---|---|
devkit.generate-document | Generate professional documents (assessments, features, analysis, process, custom) |
devkit.generate-changelog | Generate and manage changelog following Keep a Changelog standard |
devkit.generate-security-assessment | Generate security assessment document after audit |
| Command | Purpose |
|---|---|
devkit.github.create-pr | Create GitHub pull request with branch creation and commits |
devkit.github.review-pr | Comprehensive PR review with code quality, security, and best practices |
| Command | Purpose |
|---|---|
devkit.lra.init | Initialize LRA environment (feature list, progress file, init.sh) |
devkit.lra.add-feature | Add a new feature to the feature list |
devkit.lra.checkpoint | Create checkpoint (commit changes, update progress, leave clean state) |
devkit.lra.mark-feature | Mark feature as completed (passed) or failed |
devkit.lra.recover | Recover from broken state (diagnose, revert if needed) |
devkit.lra.start-session | Start coding session (read progress, choose next feature, run tests) |
devkit.lra.status | Show project status (features progress, recent activity, next priorities) |
/developer-kit:devkit.lra.init "Chat app with user auth and AI responses"
/developer-kit:devkit.lra.start-session
/developer-kit:devkit.lra.checkpoint "Implemented user registration"
/developer-kit:devkit.github.create-prSkills are specialized capabilities invoked with /skill-name. Each skill includes detailed reference documentation.
| Skill | Purpose | Trigger |
|---|---|---|
adr-drafting | Create Architecture Decision Records | User decides on architectural change, needs to document technical rationale |
memory-md-management | Manage CLAUDE.md files | User asks to check, audit, update, improve, or validate project memory files |
docs-updater | Update documentation | Preparing release, maintaining documentation sync, updating changelog |
drawio-logical-diagrams | Create draw.io diagrams | Creating logical flow diagrams, system architecture, BPMN, UML, data flow |
github-issue-workflow | Resolve GitHub issues | User asks to resolve, implement, work on, fix, or close a GitHub issue |
learn | Extract project patterns | User asks to "learn from project", "extract project rules", "analyze conventions" |

/github-issue-workflow GH-123A security hook that prevents execution of destructive Bash commands.
Location: hooks/prevent-destructive-commands.py
Configuration: hooks/hooks.json
Security Features:
rm, unlink, rmdir, shred targeting paths outside working directory.env, SSH keys, AWS credentials, private keys)Commands support --lang parameter to use specialized language-specific agents:
| Language | Agents Used |
|---|---|
| Java/Spring Boot | spring-boot-backend-development-expert, java-software-architect-review |
| TypeScript/NestJS | typescript-software-architect-review, nestjs-backend-development-expert |
| React | react-frontend-development-expert, react-software-architect-review |
| Python | python-software-architect-expert, python-code-review-expert |
| AWS | aws-solution-architect-expert, aws-cloudformation-devops-expert |
| General | general-code-explorer, general-software-architect, general-code-reviewer |
Specifications-driven development commands have been extracted to a dedicated plugin.
Commands: /specs:brainstorm, /specs:spec-to-tasks, /specs:task-implementation, /specs:task-manage, /specs:task-review
Skills: knowledge-graph — Persistent Knowledge Graph for specifications
Installation: For teams using specifications-driven development, install both developer-kit-core and developer-kit-specs.
None — this is the foundational plugin upon which all other Developer Kit plugins depend.
