Most Cowork users install a Plugin and never customize it.

Default Plugin configurations are generic by design. The gap between a default Cowork setup and a customized one is the gap between a tool that is useful and a tool that feels built for you.

Customize every Plugin before using it seriously.

Click Customize on any installed Plugin to open a setup session where you describe exactly how you work. What you tell Claude during customization becomes embedded in how the Plugin's Skills behave. Five to fifteen minutes per Plugin dramatically improves output relevance.

Customize: your specific role, the format and structure you want Skills to produce, tone and communication style, names of systems and tools your Skills should reference, and what the Skill should always or never do.

Skill chaining – compound automation in one command.

Chain multiple Skills in a single message: /prospect-research [company name] then use those findings to draft a /email-followup for the account executive role runs two Skills in sequence, passing the first's output as context for the second. Effective Skill chains: gather context first, act on it second.

Managing Connectors – authorization, permissions, troubleshooting.

Connectors lose authorization when passwords change or OAuth tokens expire. Signs: a Skill that used to work returns "Connector not available" or empty results. Fix: go to Customize in the Cowork sidebar, find Connectors, and re-authenticate the affected one.

Best practice: review active Connectors monthly and revoke any no longer in active use. Unused authorized Connectors represent ongoing data access you do not need.

Routines – building your automated workflow.

Advanced Routine techniques:

• Combine multiple Skills in one Routine: a morning briefing can pull email summary, calendar overview, and priority tasks in one scheduled run
• Use plain language for scheduling: "Every weekday at 8am" is a valid schedule – no cron syntax required
• Name Routines meaningfully: "Monday Planning Routine" is more useful than a default name
• Test a Routine manually before scheduling it: run the Skills in sequence first to confirm output
• Routines require the desktop app to be open and computer awake

Sub-agents in Cowork.

For multi-part tasks, describe parallel components and Claude will spawn sub-agents to handle each concurrently: "In parallel: research [topic A] from my Google Drive, pull this week's calendar, and summarize my last five email threads from [client name] in Gmail. Then compile all three into a daily briefing." One prompt, three parallel operations, one combined output.

The Profile – the most overlooked Cowork setting.

The Profile section in Cowork Customize is where you describe yourself, your role, and your working style. This shapes how every Plugin's Skills frame their outputs. If you have not filled out your Cowork Profile, every Skill is working without its most important context.
