If you have started using Claude Cowork, you will have seen mention of plugins and wondered whether you should install them all. The short answer is no. Plugins are useful precisely because they are specific, and the skill is choosing the few that match the work you actually do. This is a practical guide to what plugins are, what the main packs cover, and how to pick without cluttering your setup with things you will never run.
What plugins are in Cowork
A plugin bundles skills, connectors, and workflows for a particular job function. Installing one teaches Cowork the playbooks of that role: the small business pack knows how to run a month-end close, the sales pack knows how to run a pipeline review. The skills inside a plugin are step-by-step procedures Claude follows, which is what makes the output consistent rather than improvised. Think of a plugin as hiring an assistant who already knows the standard routines of a specific role, instead of one you have to teach from scratch.
The packs that matter for an Australian SMB
Four packs cover most of what a small or mid-sized Australian business needs.
Small business: cash-flow snapshots, invoice chasing, month-end prep, customer pulse checks, and Monday and Friday briefs.
Sales: account research, call prep and summaries, pipeline review, forecasting, and outreach drafting.
Marketing: campaign planning, content drafting, competitive analysis, and performance reporting.
Productivity: task tracking and memory, so the assistant remembers your shorthand, your projects, and how your business refers to things.
It helps to separate two things a plugin gives you: connectors and skills. Connectors are the links to your systems, such as email, calendar, or your CRM, and they are scoped so each one is approved on its own. Skills are the written procedures that tell Claude how to do a job in a consistent order. A pack ships both, but you do not have to switch everything on. Enabling the two or three skills you will actually use, and only the connectors they need, keeps the setup tidy and the permissions tight.
Choosing well
The mistake to avoid is installing for coverage. Three rules keep a setup clean and useful.
Install for the workflows you run weekly, not for completeness. An unused plugin is just clutter that makes the useful ones harder to find.
Start with one function. Prove the value in finance or sales before spreading sideways into everything else.
Reach for custom skills once a workflow repeats. A skill written for your own quoting process will outperform any off-the-shelf pack.
The general pattern is that breadth is tempting and depth is what pays. A business running three plugins well is in a far better position than one that installed a dozen and uses none of them properly. Treat each plugin as a commitment to actually use it, not a box to tick.
A quick word on how to trial a pack. Give it a fortnight on a real recurring task before deciding whether it stays. Plugins look impressive in a demo and only prove themselves against your actual work, with your files and your quirks. If a pack has not earned a place in your weekly routine within two weeks, it probably is not the right one for your business, and removing it costs nothing. The point is to end up with a small set you trust, not a long list you ignore.
What plugins cost
The packs themselves ship with the platform, so the plugins are not where the money goes. The real investment is configuration and workflow design: connecting them to your systems, scoping access, and tuning the workflows to how your business actually operates. A professional setup with two or three working workflows typically starts around $8,000 AUD, set against admin time savings that commonly reach $25,000 a year per document-heavy role. The packs give you a head start. The configuration is what turns that head start into a result.
Where custom skills come in
Off-the-shelf packs are the right starting point, but the biggest gains usually come from custom skills written for your business. Commission one when a procedure is repeatable, high-volume, and specific to how you work, with a clear definition of done. A custom skill for your quoting process, your engagement onboarding, or your particular reporting format captures the way your business does it, and it produces the same quality every time without anyone having to remember the steps. That is where a generic assistant becomes your assistant.
We handle plugin and skill configuration as part of a Cowork rollout, and the training to use them well. If you are not sure which packs fit your business or whether a custom skill is worth it, book a discovery call and we will work it out with you.
