Skills: The Hidden Engine of AI Agents (And Why You Don't Need a 'Magic Bot')

Lately, tools like Moltbot (formerly Clawdbot) have broken the internet. It feels like magic: an agent that uses WhatsApp, manages your calendar, and browses the web for you. But if we open the hood, we discover that the true superpower isn’t the bot itself, but Agent Skills.

The Skill is the Message

Moltbot is, in essence, an excellent skill interpreter. It uses an open specification that allows “injecting” capabilities into any LLM. This means that intelligence isn’t hardwired into the bot’s code but documented in files that the agent reads and executes on demand.

The reality is this: you don’t need to install a complex bot to have that power. If you have the skills, you can bring that functionality to your own environment (Claude Code, Codex, or your own custom agent).

My Skills Ecosystem: The Complete Inventory

Since I started tinkering with Moltbot, and later with my own agent (aipal), I’ve been building and collecting a set of skills that allow me to automate much of my daily work.

Some of them are my own, and others are from third parties. You can find many at skills.sh, but be careful with the skills you use, as they could inject malicious prompts into your agent.

🛠️ Development & Infrastructure

• mcp-builder: The ability to manufacture my own “hands” (MCP tools) to connect any API.
• worktree-helper: To work in parallel on multiple Git branches without cluttering the main environment.
• webapp-testing: Use of Playwright for the agent to navigate, test, and capture errors in real-time.
• 3rd-web-artifacts-builder: Creation of complete React/Tailwind applications in a single step.
• create-cli: For the agent to design professional command-line tools for me.

📧 Communication & Presence

• bird-cli: My “radar” on X. Daily briefings, trend searching, and mention management.
• whatsapp-evo, slack & email: My three main channels unified. The agent can read, summarize, and propose replies.
• google-chat: Access to threads and collaborative workspaces.
• postiz: Automated scheduling and publishing on all my social networks.

🎥 Content & Academy

• youtube-publish & short-publish: The complete flow: from uploading the video to burning subtitles with Whisper and creating social posts.
• weekly-newsletter: The intelligence that distills the best of my week into a draft for my newsletter.
• academy-enrollments & zoom-recordings-manager: All DevExpert operations automated.
• devexpert-testimonials: Intelligent management of social proof and website updates.

🧠 Productivity & Analysis

• morning-routine: My starting ritual: a sweep of all my channels to give me the state of the nation.
• total-recall: Infinite memory of all our past conversations and decisions.
• grok-research: Deep investigations with real-time data and source verification.
• justdoit: Management of Google Tasks and calendar from the chat.
• pdf: Advanced data extraction, document merging, and PDF form management.
• holded-invoices: Automatic detection of invoices in email and direct upload to my accounting platform.

⚡ Synergies: When Skills Collaborate

The true power emerges when the agent combines these pieces like LEGO blocks.

There are skills that use other skills, or we can even use them in sequence to create complex workflows.

1. The Creator Synergy:
   • Workflow: short-publish transcribes a video -> gemini generates copy -> postiz schedules it -> weekly-newsletter includes it in the summary -> browser-tools verifies that the post looks good on LinkedIn.
2. The Administrative Synergy:
   • Workflow: email detects an invoice from a provider -> pdf extracts the amount and date -> holded-invoices uploads it to accounting -> justdoit creates a task for me to confirm the payment.
3. The Research Synergy:
   • Workflow: bird-cli detects a new AI trend -> grok-research does a deep dive on the topic -> doc-coauthoring helps me write a technical thread -> postiz publishes it -> total-recall archives it so I never forget it.

Does this completely invalidate the use of a tool like MoltBot? Not necessarily, but skills give you great power without needing to depend on a lot of pieces you might not need.
