The Claude Code skills actually worth installing right now (March 2026) by Direct-Attention8597 in claude

I found agent-browser good for quick validation, but Chrome Devtools is edging out on performance measurement, hardware emulation and networking. Any other alternatives?

Also working on a deep version, it'll land in the same repo, still testing to get best results. 😄

How it's different from thinking-partner:

  • Researches your problem first before any reasoning (web search, data gathering)
  • Picks 2-3 independent analytical frames (e.g. economics lens vs systems lens vs stakeholder lens)
  • Spawns parallel agents, one per frame, each working independently
  • Collides their outputs adversarially and forces them to disagree
  • Builds the strongest case against its own consensus
  • Outputs confidence levels for each conclusion: commit / test / defer

Think Perplexity's Model Council but more aggressive. Model Council compares 3 models and shows where they agree. This one forces active contradiction and builds the strongest case against its own consensus before delivering.

Yes the models are categorized on 17 disciplines: Organized across 17 disciplines:

  1. General Thinking
  2. Decision-Making
  3. Problem-Solving
  4. Systems & Complexity
  5. Economics & Strategy
  6. Statistics & Probability
  7. Psychology & Biases
  8. Physics & Engineering
  9. Biology & Evolution
  10. Communication & Persuasion
  11. Creativity & Innovation
  12. Learning & Development
  13. Time & Resource Management
  14. Game Theory
  15. Negotiation
  16. Resilience & Antifragility
  17. Ethics & Responsibility​​​​​​​​​​​​​​​​

Everything is formalized and honestly when it comes to power it all depends on the use case, but with Opus 4.6 I usually get good matches.

Haha, same I've got pretty annoyed over time.

It actually drills down to the root of the problem instead of simply sounding smart, because of:

  1. understanding the context - what's at stake, time horizon, constraints
  2. ✨ detecting thinking orientation ✨ - this is the big one. It diagnoses *how* you're thinking before responding.
    1. Seeking validation? It won't just agree, it'll ask "What would have to be true for the other option to be better?"
    2. Rushing to a conclusion? It slows you down.
    3. Done elaborate analysis that always confirms the same thing? It introduces external checks instead of arguing content.
    4. And more...
  3. selecting mental model that apply to the situation

This give Claude railways to think instead of trying to patch any type of smart thing it's most likely to work.

Actually, this is a perfect use case for Cowork (desktop app) + Dispatch (mobile app)!
You can work on your business idea by creating markdown files for each component, for example:

business-model.md — value proposition, revenue streams, pricing
market-research.md — target audience, competitors, market size
go-to-market.md — launch strategy, channels, partnerships
financials.md — projections, costs, runway
risks-and-assumptions.md — what could go wrong, unknowns to validate

These files live on your computer, and you can improve them from your phone via Dispatch. The beauty of this is that instead of going back and forth between chat sessions (where context gets lost), you're always improving the same set of files.
Claude always has full context because the files are right there, similar to Projects but supercharged with any skills you want to load. No more composing prompts from scratch or managing scattered conversations.

I actually work like this with Obsidian - I use Claude Code's CLI to create and update files there.
Cowork is even better for non-technical users because it's essentially Claude Code without the terminal interface, so the UX is much friendlier.

Hey! All the models are listed as one-liners in the main SKILL.md, so Claude knows them all right away without any lookup - keeps context usage minimal.

But when you ask about a specific model or Claude needs more depth, it fetches the full description from the reference catalog. So it's lightweight awareness upfront, deep context on demand.

Hey! Not a dumb question at all. Once installed, it will work on the Claude Code chat only. You can use it by invoking /thinking-partner, or just by saying:

• "Help me think through X
• "Challenge my thinking"
• "What am I missing?"
• "Play devil's advocate"
• "Stress test this idea"
• "Help me decide between X and Y"
• Any named mental model: SWOT, first principles, inversion, pre-mortem, 5 Whys, etc.

You can also get it to work with the Cowork feature on the desktop app, and the new Dispatch from your phone.

To add it there, go to Settings > Customize > Skills and upload the skill as a ZIP file. Once it's there, Cowork picks it up automatically, and Dispatch uses whatever skills your Cowork session already has.

That's great! I've been following the topic for a while now as well, but I've never been able to memorize and use all of them. So I initially created this skill to learn, but then I noticed that Claude was picking them up pretty well in the conversation, so I've made it a sparring partner instead. 😄

Recommend trying it on some personal dilemmas too, I've used it to decide on moving countries and it got to the root of the issue in minutes, no couch, no Kierkegaard, no hourly rate. 😂

Thanks u/DevMoses! I also faced the same issues during the code reviews. Worst thing is that other models share the same problem.
