Example Plugins

Three complete plugin structures at different complexity levels. Use these as templates when implementing in Phase 4.

Minimal Plugin: Single Skill

A simple plugin with one skill and no other components.

skills/meeting-notes/SKILL.md

---
name: meeting-notes
description: >
  Generate structured meeting notes from a transcript. Use when the user asks
  to "summarize this meeting", "create meeting notes", "extract action items
  from this transcript", or provides a meeting transcript file.
---

Read the transcript file the user provided and generate structured meeting notes.

Include these sections:

1. **Attendees** — list all participants mentioned
2. **Summary** — 2-3 sentence overview of the meeting
3. **Key Decisions** — numbered list of decisions made
4. **Action Items** — table with columns: Owner, Task, Due Date
5. **Open Questions** — anything unresolved

Write the notes to a new file named after the transcript with `-notes` appended.

Standard Plugin: Skills + MCP

A plugin that combines domain knowledge, user-initiated actions, and external service integration.

skills/review-changes/SKILL.md

---
name: review-changes
description: >
  Review code changes for style and quality issues. Use when the user asks to
  "review my changes", "check this diff", "review for style violations", or
  wants a code quality pass on uncommitted work.
---

Run `git diff --name-only` to get the list of changed files.

For each changed file:

1. Read the file
2. Check against the coding-standards skill for style violations
3. Identify potential bugs or anti-patterns
4. Flag any security concerns

Present a summary with:

- File path
- Issue severity (Error, Warning, Info)
- Description and suggested fix

skills/fix-lint/SKILL.md

---
name: fix-lint
description: >
  Auto-fix linting issues in changed files. Use when the user asks to
  "fix lint errors", "clean up linting", or "auto-fix my lint issues".
---

Run the linter: `npm run lint -- --format json 2>&1`

Parse the linter output and fix each issue:

- For auto-fixable issues, apply the fix directly
- For manual-fix issues, make the correction following project conventions
- Skip issues that require architectural changes

After all fixes, run the linter again to confirm clean output.

skills/coding-standards/SKILL.md

---
name: coding-standards
description: >
  This skill should be used when the user asks about "coding standards",
  "style guide", "naming conventions", "code formatting rules", or needs
  guidance on project-specific code quality expectations.

  version: "0.1.0"

# Coding Standards

Project coding standards and conventions for consistent, high-quality code.

## Core Rules

- Use camelCase for variables and functions
- Use PascalCase for classes and types
- Prefer const over let; avoid var
- Maximum line length: 100 characters
- Use explicit return types on all exported functions

## Import Order

1. External packages
2. Internal packages (aliased with @/)
3. Relative imports
4. Type-only imports last

## Additional Resources

- **`references/style-rules.md`** — complete style rules by language

Full-Featured Plugin: All Component Types

A plugin using skills, agents, hooks, and MCP integration with tool-agnostic connectors.

agents/ticket-analyzer.md

---
name: ticket-analyzer
description: Use this agent when the user needs to analyze tickets, triage incoming issues, or prioritize a backlog.

<example>
Context: User is preparing for sprint planning
user: "Help me triage these new tickets"
assistant: "I'll use the ticket-analyzer agent to review and categorize the tickets."
<commentary>
Ticket triage requires systematic analysis across multiple dimensions, making the agent appropriate.
</commentary>
</example>

<example>
Context: User has a large backlog
user: "Prioritize my backlog for next sprint"
assistant: "Let me analyze the backlog using the ticket-analyzer agent to recommend priorities."
<commentary>
Backlog prioritization is a multi-step autonomous task well-suited for the agent.
</commentary>

You are a ticket analysis specialist. Analyze tickets for priority, effort, and dependencies.

**Your Core Responsibilities:**

1. Categorize tickets by type (bug, feature, tech debt, improvement)
2. Estimate relative effort (S, M, L, XL)
3. Identify dependencies between tickets
4. Recommend priority ordering

**Analysis Process:**

1. Read all ticket descriptions
2. Categorize each by type
3. Estimate effort based on scope
4. Map dependencies
5. Rank by impact-to-effort ratio

**Output Format:**
| Ticket | Type | Effort | Dependencies | Priority |
|--------|------|--------|-------------|----------|
| ... | ... | ... | ... | ... |

Followed by a brief rationale for the top 5 priorities.

CONNECTORS.md

# Connectors

## How tool references work

Plugin files use `~~category` as a placeholder for whatever tool the user
connects in that category. Plugins are tool-agnostic.

## Connectors for this plugin

| Category        | Placeholder         | Included servers | Other options       |
| --------------- | ------------------- | ---------------- | ------------------- |
| Project tracker | `~~project tracker` | Linear           | Asana, Jira, Monday |
| Chat            | `~~chat`            | Slack            | Microsoft Teams     |
| Source control  | `~~source control`  | GitHub           | GitLab, Bitbucket   |
