Sharing a Claude project with a team

Why a shared project isn't just "let everyone use the same account"

The naive version of team sharing — everyone logging into one shared account — loses exactly the thing that makes a project useful as a team resource: attribution, individual context, and the ability to tell whose work is whose when something needs to be revisited or corrected. A properly shared project keeps the shared material — instructions, reference documents, accumulated context — common to the team while keeping each person's own working sessions distinguishable from everyone else's.

What actually belongs in the shared layer

Not everything that's useful to one person belongs promoted to the shared project level. The material worth sharing is what's genuinely stable and relevant to everyone using the project — the actual reference documents, the conventions the whole team should follow, context that doesn't change based on who's asking. A team member's personal working notes or a one-off exploration they're doing individually doesn't belong mixed into the shared layer, where it adds noise for everyone else without adding value for anyone besides the person who put it there.

The maintenance cost nobody accounts for upfront

A shared project's reference material needs active upkeep the same way any shared documentation does — content that was accurate when the project was set up drifts out of date as the underlying work evolves, and nobody individually owns fixing that unless someone's actually assigned to. A project that was carefully set up once and never revisited tends to accumulate stale context that actively misleads anyone relying on it being current, which is a worse outcome than having no shared context at all, since at least an empty project doesn't assert something false with confidence.

Access control matters more as a project grows

A project that starts with two or three trusted collaborators and grows to include a wider team over time needs its access and content reviewed against that larger audience, not left exactly as it was configured for the original small group. Reference material or instructions that were fine to share with a founding team member might not be appropriate for a broader audience the project eventually reaches — review who has access as deliberately as you'd review it for any other shared resource, rather than letting it accumulate access by default as people join.

Onboarding new members without re-explaining everything by hand

A well-maintained shared project should be able to onboard a new team member largely on its own — if a new person joining still needs a lengthy manual walkthrough before the shared context is actually useful to them, that's usually a sign the project's own material isn't as self-explanatory as it needs to be, not that onboarding inherently requires a human explainer. Treating "can a new person get productive from the shared project alone" as an explicit test, periodically, surfaces gaps in the shared material faster than waiting for someone to struggle through onboarding and mention it after the fact.

Deciding what gets removed, not just what gets added

A shared project tends to accumulate content readily but rarely gets anything deliberately removed — old context stays in place because removing it feels riskier than leaving it, even once it's no longer accurate. Treat pruning outdated shared material as an explicit, regular part of maintaining the project, not an afterthought that only happens when something stale actively causes a visible problem; by the time a stale piece of context causes a visible problem, it's usually already misled several people who never mentioned it.

Assigning real ownership, not assuming it's collectively maintained

A shared resource with no named owner tends to decay the way any unowned resource does — everyone assumes someone else is keeping it current. Naming an actual person responsible for the shared project's health, even informally, is what actually keeps it useful past the first few weeks after setup.
