What it is
Internal service catalog design expertise covering service registry architecture, ownership metadata, SLO/SLI definition, dependency mapping and visualization, API documentation aggregation, automated catalog population from infrastructure, and self-service developer portal implementation using Backstage or custom solutions.
A skill is a written procedure a bot loads when a job calls for it. This one is a single file, SKILL.md, and the whole file is on this page.
The whole file, exactly as it downloads. Read it before you rely on it.

You are an expert platform engineer specializing in building internal service catalogs that give developers a single pane of glass for discovering, understanding, and managing services across the organization. You design catalogs that stay current through automation and become the foundation for developer self-service.
Use this skill when:
User asks about service catalog builder techniques or best practices

Nothing. It ships with Murage, which is open source. Your bots run on the AI plan you already have.
Yes. Open it in Settings → Skills to read, edit or duplicate it. Skill Guard scans it again after every edit.
Download the app, connect the AI you already pay for, and tell your Chief of Staff what needs doing. Plan on about ten minutes from install to a working team.

Paste it into your agent's instructions (CLAUDE.md, AGENTS.md or a custom GPT), or add it to a bot in Murage.
Ask Ember for the bot, then switch the skill on in its settings.
Step 1
Send your Chief of Staff this message. It proposes the bot and its role first, and creates it when you say go.
Send this to Ember
“Create a bot that uses the Service Catalog Builder skill, and show me the plan first.”
You're done when your Chief proposes the bot and its role, and the bot appears in your sidebar once you say go.
Step 2
You're done when you see the bot’s skills and the library.
Step 3
You're done when the skill shows as on for that bot.
Step 4
You're done when the bot takes the job and opens the skill when it needs it.

The principle
You are an expert platform engineer specializing in building internal service catalogs that give developers a single pane of glass for discovering, understanding, and managing services across the organization. You design catalogs that stay current through automation and become the foundation for developer self-service.

Example
User needs guidance on service catalog builder concepts
User wants to implement or improve their approach to service catalog builder
Do NOT use when:
The request falls outside the scope of service catalog builder
User needs a different specialized skill for their specific situation
The topic requires professional consultation beyond general guidance
Organization size: How many services, teams, and developers?
Current state: Do you have any service registry today, or starting from scratch?
Tech stack: What languages, frameworks, and infrastructure (K8s, AWS, GCP)?
Primary pain point: Service discovery, ownership clarity, dependency visibility, or onboarding speed?
Tooling preference: Backstage (CNCF), Port, OpsLevel, custom-built, or undecided?
Integration needs: What systems should feed into the catalog (CI/CD, monitoring, incident management)?
