Creating New Skills

Skills follow the Agent Skills specification. Each skill requires a SKILL.md file with YAML frontmatter.

Skill Template

Create a new directory under plugins/sentry-skills/skills/:

plugins/sentry-skills/skills/my-skill/
└── SKILL.md

SKILL.md format:

---
name: my-skill
description: A clear description of what this skill does and when to use it. Include keywords that help agents identify when this skill is relevant.
---

# My Skill Name

## Instructions

Step-by-step guidance for the agent.

## Examples

Concrete examples showing expected input/output.

## Guidelines

- Specific rules to follow
- Edge cases to handle

Naming Conventions

• name: 1-64 characters, lowercase alphanumeric with hyphens only
• description: Up to 1024 characters, include trigger keywords
• Keep SKILL.md under 500 lines; split longer content into reference files

Optional Fields

Field	Description
license	License name or path to license file
compatibility	Environment requirements (max 500 chars)
allowed-tools	Comma-separated list of tools the skill can use
metadata	Arbitrary key-value pairs for additional properties

---
name: my-skill
description: What this skill does
license: Apache-2.0
allowed-tools: Read, Grep, Glob
---

Where Skills Belong

Skills should live in the appropriate location based on their scope:

Scope	Location	Example
Global - Used across Sentry	sentry-skills plugin	commit, code-review, create-pr
Domain-specific - Used by a team or domain	Dedicated plugin in this repo (e.g., infra-skills)	gcp-logs, terraform-review
Repo-specific - Only relevant to one repo	The repository itself (.claude/skills/)	Project-specific workflows

When deciding where to place a skill:

• If most Sentry engineers would benefit, add it to sentry-skills
• If only a specific team needs it, create or use a domain-specific plugin
• If it only makes sense in one repo, keep it in that repo

Marketplace Structure

This repository is a Claude Code marketplace - a collection of plugins that can be installed independently. The marketplace manifest (.claude-plugin/marketplace.json) lists all available plugins:

{
  "plugins": [
    { "name": "sentry-skills", "source": "./plugins/sentry-skills" },
    { "name": "infra-skills", "source": "./plugins/infra-skills" }
  ]
}

Each plugin lives in its own directory under plugins/ with its own plugin.json manifest. Users can install individual plugins:

# Install just the global skills
claude plugin install sentry-skills@sentry-skills

# Install domain-specific skills
claude plugin install infra-skills@sentry-skills

To add a new domain-specific plugin:

1. Create plugins/<plugin-name>/.claude-plugin/plugin.json
2. Add skills under plugins/<plugin-name>/skills/
3. Register the plugin in .claude-plugin/marketplace.json

Vendoring Skills

We vendor (copy) skills and agents that we use regularly into this repository rather than depending on external sources at runtime. This approach:

• Ensures consistency - Everyone on the team uses the same version of each skill
• Enables customization - We can adapt skills to Sentry-specific conventions
• Improves reliability - No external dependencies that could change or disappear

Attribution

When vendoring a skill or agent from an external source, retain proper attribution:

1. Add a comment at the top of the file referencing the original source:

   <!--
   Based on [Original Name] by [Author/Org]:
   https://github.com/example/original-source
   -->

2. Include a LICENSE file in the skill directory if the original has specific licensing requirements:

   plugins/sentry-skills/skills/vendored-skill/
   ├── SKILL.md
   └── LICENSE      # Original license text
   

Example: code-simplifier

The code-simplifier agent is vendored from Anthropic's official plugins. See the attribution comment at the top of the agent file.
