In `@skills/cmux-billing/SKILL.md`:
- Line 34: Update the billing description near the paid Cloud VM allowance to
document that Team’s 50 active-VM allowance is per paid seat and multiplies
across the billing team, rather than implying a fixed team-wide cap. Preserve
the existing shared resource limits and references to machineSpec.ts and
pro-pricing.test.ts.
In `@web/services/vms/machineSpec.ts`:
- Around line 4-5: Update the pricing copy near maxActiveVms to describe the 20
GB memory, 5 vCPU, and 200 GB disk values as per-VM sizing, unless the
implementation is changed to enforce aggregate resource limits across active
VMs. Keep the wording consistent with Freestyle.growToRequestedSize and the
enforced maxActiveVms entitlement.
In `@web/tests/pro-pricing.test.ts`:
- Around line 130-134: Strengthen the pricing test’s Team-column assertions to
require the expected RAM and disk capacity values in addition to vCPU, using the
existing capacity-row data and locale handling. Update the FAQ assertion to
require the complete shared-capacity wording, including both the per-user text
and the new capacity sentence, rather than only rejecting stale per-VM wording.

supported locales beyond en and ja, using the repository-approved English
fallback where translations are unavailable and preserving the existing en/ja

- Line 770: Align the pricing copy and entitlement behavior represented by the
VM allowance with the enforced storage quota: either add aggregate disk-usage
enforcement for the shared 200 GB pool, or revise the 50-VM allowance and
related text to match the actual quota. Update the relevant pricing default
value and entitlement/quota symbols consistently, preserving the stated
no-overage behavior.
In `@web/services/vms/machineSpec.ts`:
- Around line 3-6: Update the module documentation to accurately state the
enforcement boundary: `create` enforces only `maxActiveVms`,
`FreestyleProvider.growToRequestedSize` applies the CPU and memory profile per
VM, and `resizeVm` enforces the per-VM 256 GiB disk ceiling. Only describe the
advertised CPU, memory, and disk values as a shared pool if an external billing
or provider boundary enforces that aggregate capacity; otherwise document them
as per-VM limits.

- Around line 13-17: Update the PLAN_SHARED_* capacity constants to cover the
full 50-VM allowance, ensuring shared CPU, memory, and disk totals are scaled
consistently with the per-VM reservations used by
sharedResourceCapacityForMaxActiveVms and firstExceededSharedResource.
In `@web/services/vms/repository.ts`:
- Line 538: Update reservedResourceTotals to use the personal-account scope when
billingTeamId is null, matching the accountScopeWhere behavior. Pass the user
scope and apply the corresponding null billingTeamId predicate so sibling
personal VMs are included in resize capacity calculations. Preserve billing-team
matching for non-null scopes.

- Around line 536-537: Update vmSharedResourceLimitExceededResponse and every
caller across the VM route paths to accept vmRequestLocale(request), resolve
both message and action through the existing vmErrors catalog, and make the
helper/callers asynchronous where needed. Add the corresponding localization
keys to every locale configured in web/i18n/routing.ts while preserving the
existing resource interpolation and response behavior.
- Around line 536-537: Update vmSharedResourceLimitExceededResponse to
distinguish requested capacity exceeding the shared resource limit from
rejection caused by existing usage: when requested is greater than limit, return
guidance to choose a smaller supported target; retain the
delete-an-unused-Cloud-VM action only when used capacity causes the pool to be
full.
In `@web/services/vms/workflows.ts`:
- Around line 2067-2069: Update the resize workflow around providers.resize to
import Exit from effect/Exit and replace Effect.tapError with Effect.onExit,
invoking rollbackReservation for every exit that is not successful while
preserving the existing resize operation.
