Use Cases

Real-world ways to use claude-skills

Get an architecture review before you commit to a stack

👤 Tech leads starting a new service ⏱ ~30 min intermediate

When to use: You're about to pick a framework and database for a new product and want a sanity check.

Flow
  1. Describe the service
    Use the engineering skills. We need a real-time collab API — 10k concurrent users, document sync, presence. Compare Node+WebSocket vs Elixir+Phoenix vs Go+gRPC.✓ Copied
    → Comparison grounded in real tradeoffs from the respective skills
  2. Probe risks
    For the choice you'd recommend, what fails at 100k users?✓ Copied
    → Concrete scaling cliffs, not generic platitudes

Outcome: A decision doc with tradeoffs and scaling risks identified.

Pitfalls
  • Skill over-recommends the framework it has the deepest skill for — Ask it to explicitly state why NOT each option

Run an incident response playbook for a production outage

👤 On-call engineers during a live incident ⏱ ~15 min advanced

When to use: Production is on fire and you need structured triage without panicking.

Flow
  1. Open the incident
    Use the incident-response skill. Symptoms: API 500s spiking in US-east, started 10 min ago.✓ Copied
    → Claude walks through structured diagnosis — triage tree, log queries, mitigation options
  2. Follow-up postmortem
    Now draft the postmortem template using what we learned.✓ Copied
    → Filled-in template with blameless framing

Outcome: Faster time-to-mitigate and a credible postmortem.

Pitfalls
  • Skill suggests generic mitigations without knowing your stack — Tell it your stack upfront — 'we're on AWS ECS + RDS Postgres'
Combine with: aws · sentry

Use the CTO skill to pressure-test a board deck

👤 Founders and CTOs prepping for fundraising ⏱ ~45 min advanced

When to use: You have the tech section of a deck and want senior-CTO red team feedback.

Flow
  1. Share the slides
    Use the CTO advisory skill. Here's our tech architecture slide — what would a skeptical board member ask?✓ Copied
    → Specific, pointed questions tied to slide content
  2. Prep answers
    For each question, draft a crisp answer with data we'd need to back it up.✓ Copied
    → Prep notes you can actually rehearse

Outcome: A rehearsed Q&A for the tech portion of your board meeting.

Pitfalls
  • Questions feel generic — Feed in your actual architecture docs, not just the deck summary

Combinations

Pair with other MCPs for X10 leverage

claude-skill + github

Engineering skills suggest the change; GitHub MCP opens the PR

Use the backend skill to design the refactor, then open a PR in our repo with the plan as the description.✓ Copied
claude-skill + filesystem

Skills produce docs; filesystem stores them in the repo

Save the architecture review output to docs/architecture/ and create a README index.✓ Copied

Cost & Limits

What this costs to run

API quota
None
Tokens per call
Varies wildly by skill; big skills load 5-15k tokens of references
Monetary
Free — skills are local
Tip
The library is too big to let Claude browse freely. Name the skill or domain in the prompt.

Security

Permissions, secrets, blast radius

Credential storage: No credentials — skill is prompts
Data egress: None from the skill itself

Troubleshooting

Common errors and fixes

Claude picks the wrong skill for a task

Reference by domain: 'use the marketing > SEO skill'. With 235+ skills, auto-routing is fuzzy.

SKILL.md loads are too large

Pin to one skill at a time; don't try to load multiple domains in one prompt.
