Build a service catalog — schema, starter entries, and governance model. Produces what information to capture per service, how it's maintained, and where it lives. Use when asked to "service catalog", "what services do we have", "catalog our services", "service inventory", or "who owns what".

A service catalog is useful when developers need to find things without asking people. It fails when it becomes a stale spreadsheet nobody trusts. The right catalog is the simplest one that answers the questions developers actually ask — and has a governance model that keeps it current.
Start with the questions, not the schema.
Before designing the catalog, establish what problem it's solving:
If the answer to all of these is "not really a problem yet," the catalog is premature. Document it as a lightweight table in the root README instead.
If the pain is real, continue.
Also check:
catalog-info.yaml, Backstage configs, Port/Cortex/OpsLevel setup, any wiki pagesWrite down only the fields developers actually need. Every field you add is a field someone has to keep updated.
Minimum viable schema (every service must have these):
# catalog-info.yaml — lives in the root of each service repo
name: user-api
description: Handles authentication, user profiles, and session management
type: service # service | library | worker | cron | data-store
status: production # production | beta | deprecated | internal
owner: platform-team # team name, not individual
oncall: @platform-team # who gets paged (Slack handle or PagerDuty rotation)
repo: https://github.com/org/user-api
docs: https://notion.so/org/user-api-runbook
dashboard: https://grafana.org/d/user-api
Extended schema (add only when the pain exists):
# Add these when they answer a question that comes up repeatedly
language: python
framework: fastapi
deploy_target: fly.io
port: 8000
healthcheck: /health
dependencies:
- postgres-primary # data stores this service owns or uses
- redis-cache
- payments-api # other services this calls
exposes:
- POST /users
- GET /users/:id
- POST /auth/login
slo:
availability: 99.9%
latency_p99: 200ms
Do not add fields speculatively. Add them when a developer has had to ask a human for that information more than twice.
Discover what exists. Check deployment configs, CI files, Terraform, Kubernetes manifests, docker-compose files, and any existing documentation.
For each service, produce one catalog entry using the schema from Step 1. Write the actual entries — don't produce a template and ask the human to fill it in.
Starter inventory table (produce this as a cross-reference, not a replacement for the YAML):
| Service | Type | Owner | Status | Repo | Runbook | Dashboard |
|---|---|---|---|---|---|---|
| user-api | service | platform-team | production | link | link | link |
| web-app | service | product-team | production | link | link | — |
| email-worker | worker | comms-team | production | link | — | — |
Flag every missing field. A catalog with gaps is expected — the gaps are the backlog.
Dependency map (Mermaid, only if dependencies are unclear and causing problems):
graph LR
web-app --> user-api
web-app --> content-api
user-api --> postgres-primary
user-api --> redis-cache
email-worker --> user-api
Match the tooling to the team size and complexity:
Under 10 services — Markdown table in root README:
10–50 services — catalog-info.yaml in each repo + generated index:
50+ services or multi-team — Backstage, Port, or Cortex:
Do not adopt a catalog tool to look mature. Adopt it when the simpler approach has failed.
A catalog without a governance model is a catalog that will be stale in 90 days.
Write the governance model as a short policy, not a process diagram:
## Service Catalog Governance
**Who updates it:** The team that owns the service updates their own catalog-info.yaml.
No central team owns catalog entries — ownership is distributed.
**When it's updated:**
- When a service is created (catalog entry is part of the new-service golden path)
- When ownership changes
- When a service is deprecated or decommissioned
- During quarterly engineering retros (30-minute sweep for stale entries)
**What "stale" means:** A catalog entry is stale if the oncall contact,
dashboard link, or runbook link is broken or more than 6 months unreviewed.
**How staleness is caught:**
- CI check on catalog-info.yaml schema validity (auto)
- Quarterly link-rot sweep (manual, 30 min, owned by Pave)
- Incident retrospectives flag missing runbook links
**What happens with orphaned services:**
- No owner listed → Pave pings the last committer in Slack
- No response in 1 week → escalates to Apex for ownership assignment
The governance model must name a specific owner for the quarterly sweep. "The team" owns nothing.
Write all of the following — don't describe what to write, write it:
catalog-info.yaml for each service discovered (or a starter set if the full inventory isn't available yet)make catalog-check target or CI step that validates schema and checks for required fieldsFollow the output-kit: 40-line CLI max, box-drawing skeleton, unified severity indicators.
