🤖 Fable 5.2 via Claude Code on behalf of @cardoso-neto

Problem

Claude accounts with a $0 extra-usage cap (is_enabled: true, monthly_limit: 0, utilization: null) leave a blank cell in Usage → Limits → Monthly spend. A blank cell looks like missing data or an error.

Change

The server flags the account (zeroSpendCap) instead of dropping the budget. The pooled view draws a dashed "$0 cap" tile in that cell. Streamed window updates keep the flag.

The flag is not a window on purpose: a 100%-used window would lower the pooled "% left" and mark the account as out of usage.

Scope

Fixes #35339. Dollar amounts for other accounts are not part of this PR.

Verification

I found it on a CLIProxyAPI hub where three of eight Claude accounts have a $0 cap. I rendered UsageLimitsPooled in the browser test harness with six hub accounts, three of them with a $0 cap, with and without the flag:

Approvability

Verdict: Approved at 6813408

Macroscope's review found this PR approvable — Claude accounts with an existing $0 monthly cap now show a labeled tile instead of a blank cell. This changes usage presentation without changing spending limits or enforcement.

Walkthrough

Claude usage limits now identify enabled extra usage with a monthly limit of zero. The flag is preserved in streamed updates and displayed as a $0 cap cell in pooled monthly limits when no usage window exists.

Changes: Claude zero-spend cap handling

Layer / File(s)	Summary
Set the zero-spend-cap flag packages/contracts/src/providerUsageLimits.ts, apps/server/src/provider/claudeUsageLimits.ts, apps/server/src/provider/claudeUsageLimits.test.ts	The provider limits contract adds an optional zeroSpendCap field. Claude response conversion sets it when extra usage is enabled and the monthly limit is zero. A test covers this response.
Preserve the flag in streamed updates packages/provider-core/src/server/usageLimits.ts, packages/provider-core/src/server/usageLimits.test.ts	Streamed usage-limit updates preserve zeroSpendCap from the previous object. The test checks it alongside resetCredits.
Render zero-cap monthly cells apps/web/src/components/usage/UsageLimitsPooled.tsx	The monthly pool view renders a dashed $0 cap cell when an account has no usage window and reports a zero-spend cap. Larger layouts also show the account name.

Merge Risk: Low · up to 68134

The change makes $0-cap Claude accounts visible in the pooled monthly view. On narrow layouts, several such accounts show identical "$0 cap" cells with no account name, so users cannot tell which is which. This is a bounded presentation gap that is worth fixing before or soon after merge, and it does not affect data or other views.

Full details: Title check

Explanation

The title names the fix and its scope: Claude accounts with a $0 monthly cap no longer leave a blank cell. This matches the changeset, which flags zero-spend caps on the server and draws a dashed "$0 cap" tile in the pooled view. The title follows the conventional commit form the template asks for. It is slightly long at 78 characters.

Full details: Linked Issues check

Explanation

Issue #35339 asks that blank Monthly spend cells for Claude accounts with monthly_limit 0 and utilization null become distinguishable from missing data or errors, using a $0 cap label. The diff implements this. In apps/server/src/provider/claudeUsageLimits.ts, claudeUsageResponseToLimits sets zeroSpendCap: true when extra_usage.is_enabled is true and monthly_limit is exactly 0. It does not add a usage window. In apps/web/src/components/usage/UsageLimitsPooled.tsx, PoolBar renders a dashed '$0 cap' cell in the monthly pool column for a member with no window and zeroSpendCap set. packages/provider-core/src/server/usageLimits.ts carries the flag through streamed window updates, and the contract field is added in packages/contracts. A server test covers the zero-cap case, and a provider-core test covers flag preservation. The code checks monthly_limit only, not utilization null, so the server flag is slightly broader than the issue's full condition. The '$0 cap' label conveys the zero amount. The PR description states that dollar amounts for other accounts are excluded. I found no coding requirement left unmet. The live hub and mobile app were not checked, which is not a coding requirement of the issue.

Full details: Out of Scope Changes check

Explanation

All changed areas connect to the monthly-spend zero-cap objective. The changes are: the server flag in claudeUsageLimits.ts, its test; the optional zeroSpendCap field in the provider usage-limits contract; the flag preservation in provider-core applyUsageLimitsUpdate and its test; and the dashed '$0 cap' cell in UsageLimitsPooled.tsx. The PR description keeps the flag out of the window list on purpose, so 100%-used logic does not change. No unrelated change was found in the reviewed diffs.

Full details: Description check

Explanation

The description follows the template's main sections: Problem, Change, Scope, and Verification. It states the problem clearly: a $0 extra-usage cap leaves a blank cell in Monthly spend. It explains the server-side flag, the pooled-view tile, and why the flag is not a usage window. The Scope section links issue #35339 and says dollar amounts for other accounts are excluded. Verification gives a before/after screenshot comparison in dark and light themes and at 390px, and reports that check:changed passes. It also states what was not checked. The description names the authoring model and reviewers, which the template asks for. The Scope section does not explain why the fix is a bug fix rather than a feature, though the problem is framed as a blank-cell defect and the issue is linked. The title is not part of the description, and the template's conventional-commit title cannot be checked here.

Show the account for zero-cap cells on narrow layouts.

Below the @2xl/pool breakpoint, this hides the account name. Unlike normal segments, the zero-cap branch also renders no numbered legend row. With multiple zero-cap accounts, users cannot tell which account each cell represents. Add an account-labelled row or another accessible account identifier for each zero-cap cell.

Not changing this here. Before this PR these cells were blank at every width, so nothing regresses: the wide layout names the account, and the narrow one now says why the cell has no bar. A numbered legend row for accounts without a window is a layout change beyond #35339.

[coderabbitai]

@cardoso-neto Understood. The new labels improve on the previously blank cells, and I’ll leave the layout change outside this PR. I’m not marking the account-identification finding as addressed.

Would you like me to open a follow-up issue for narrow layouts?
