Day 5: OpenClaw Skills — Install, Combine & Build Custom Skills (2026)
OpenClaw Day 5 tutorial: explore the skills ecosystem, install skill packs, chain Gmail + calendar + search for complex tasks, and author custom skills for your hosted or self-hosted agent.
Part of the 7-day OpenClaw learning path on One Claw — SEO-friendly tutorials for hosted OpenClaw, private AI assistant, and OpenClaw skills.
Day 5 of the OpenClaw learn path is the skills tree: install community packs, chain skills for multi-step work, and sketch your first custom skill.
The OpenClaw skills ecosystem
Skills are how OpenClaw stays extensible without forking core code:
- Official & community packs — Gmail, calendar, SEO, code review, home automation
- Composable workflows — output of skill A feeds skill B
- Your IP — custom skills for internal APIs, CRM, or data warehouses
Search terms that land here: OpenClaw skills, OpenClaw skill development, AI agent workflow.
Install your first skill pack
- Browse the community registry or docs for your OpenClaw version.
- Install via CLI or dashboard (
skills install <name>pattern — follow upstream). - Restart or reload gateway if required.
- Run the skill's built-in self-test.
On One Claw, prefer skills you can also expose to non-technical users via the workspace Skills panel.
Combine skills for complex tasks
Example: Weekly growth brief
- Gmail — pull partner replies
- Calendar — list customer calls
- Search / analytics skill — pull traffic deltas
- Summarize — one Telegram message at 8:00 (scheduled on Day 6)
Document the chain in AGENTS.md so the agent knows the order and stop conditions.
Combining too many skills in one prompt increases failure rate. Prefer explicit steps or a small orchestrator skill.
Build a minimal custom skill
Skeleton concepts (names vary by OpenClaw version):
- Manifest — name, description, required env vars
- Tools — functions the model can call
- Prompt fragment — default instructions
Start from copying an existing small skill in the repo. Ship one internal integration (Notion, Jira, Stripe dashboard) your team already checks daily.
Governance for teams
- Review third-party skills like any dependency
- Pin versions; read what shell/network access they request
- Separate prod vs sandbox gateways
One Claw + skills library
Product teams often maintain:
- Gateway skills for heavy integrations
- One Claw skills library for copy-paste prompts and UI-triggered flows
Keep naming aligned so support knows which layer broke.
Day 5 checklist
- Installed ≥1 community skill pack
- Ran one multi-skill workflow successfully
- Drafted spec for one custom skill (even if not coded yet)
- Documented skill list in
AGENTS.mdor team wiki
Key takeaways
- Day 5 = breadth (install) + depth (compose + create)
- Chained skills are how AI agents beat single-shot ChatGPT
- Tomorrow: heartbeat + cron + memory for proactive delivery
