Version 2.1.190

A new rate limit type, seven_day_overage_included, tracks weekly Fable 5 usage for accounts where a defined amount is bundled into the plan. When this limit is exhausted, Claude Code now displays a specific message instead of the generic overage prompt:

• "You've reached your Fable 5 limit" — shown in the model picker and notifications
• "You've used your included Fable 5 usage for this week. Continuing on Fable 5 uses usage credits" — explains exactly what happens next

Previously, hitting any Fable 5 limit while on an account with usage credits would show the generic model-switch / credits dialog. Users on the new included-usage tier now see a distinct, accurate message. The model-switch prompt is suppressed when this limit type is active, since the appropriate next step is purchasing credits rather than switching models.

new rate limit type and display label (search for "seven_day_overage_included" and "Fable 5 limit")

The Fable 5 entry in the model picker no longer shows the older "Draws from usage credits" / "Uses your limits ~2× faster than Opus" / "Included with your plan until …" annotation strings. These have been replaced with a single concise label:

• "· Requires usage credits"

The new label applies whenever Fable 5 requires credits on the current account type, and is omitted when it does not.

removed strings (search for "Draws from usage credits" / "· Uses your limits ~2× faster than Opus" — absent from new version); added string (search for "· Requires usage credits")

The internal status endpoint (used by the IDE extensions and the API get_init_params call) now includes a model_scoped array inside the rate_limits object when the server emits per-model windows. Each entry has:

• display_name — server-supplied label for the model bucket (e.g. "Fable")
• utilization — fraction of the weekly window consumed, or null
• resets_at — ISO-8601 timestamp of window reset, or null

This field is additive: it appears only when the server returns per-model data and the list is non-empty. It gives integrators visibility into Fable 5 usage separate from the aggregate weekly limit.

new schema field (search for "Per-model weekly windows from the server limits[] array" or "model_scoped projection failed:")

Previously, when a credits_required error was returned, the overage-disabled reason was read only from the anthropic-ratelimit-unified-overage-disabled-reason response header or from a cached value. The parser now also extracts disabled_reason from the error body JSON, providing a more reliable source of the reason and reducing cases where the wrong message was shown.

new field extraction (search for "credits_required" in the 429 error handler and the overageDisabledReason property)

The prepaid credits balance fetch now checks whether the amount field in the API response is a number before using it. If the field is absent (for example, on accounts or regions where the endpoint is not supported), the fetch returns null and records a not_supported telemetry event rather than passing undefined through to the balance display.

guard added before ke("api_prepaid_balance_fetch") (search for "not_supported" in prepaid balance fetch context)

In-app announcements (the tip-bar messages shown at startup) can now declare a requiresModel field. An announcement with this field set is only shown when the currently active model matches. Previously all eligible announcements were candidates regardless of the selected model.

The startup_announcement value is also now included in the init info payload sent to extensions, allowing the IDE to display the same announcement that the CLI would show.

qCl() filter function (search for "requiresModel" in announcement filter logic) and startupAnnouncement in init payload (search for "startup_announcement")

A new feature flag tengu_saffron_credits_only_tiers (defaulting to ["enterprise"]) specifies which subscription tiers must always pay usage credits for Fable 5. Enterprise accounts without the overage tier are automatically treated as credits-only. A companion flag tengu_saffron_picker_dim allows the model picker entry to be dimmed for these accounts.

The overage consent check (yae) was also updated to respect an enabled: false field in the saffron plan config, allowing the server to explicitly disable the consent gate.
