Open the dashboard and look at the top-right corner. That little pill that says “Weekly Sonnet 0%, no reset”? Until v0.40.0, that was a lie.

Anthropic quietly retired the Sonnet weekly bucket weeks ago. The API still returns it for backward compatibility — utilization at 0, resets_at set to null — but the bucket itself is gone. Older claude-view versions saw the data and dutifully rendered it as “Weekly Sonnet, 0% used.” If you took that pill at face value, you’d think you had unlimited Sonnet headroom for the week. You didn’t. Sonnet just doesn’t have a weekly window anymore.

This is the kind of bug that’s worse than not shipping the feature at all. Wrong information destroys trust permanently — once you see one wrong number from a tool, you stop believing any of them.

What v0.40.0 does

The OAuth usage pill now follows a hard rule: if we aren’t confident, we don’t show it. Specifically:

Trust gate. Any tier where utilization is unknown, OR where utilization is exactly 0 and resets_at is null, is hidden. The decommissioned Sonnet bucket disappears entirely. So do new buckets we don’t have a label for yet but can’t read confidently.
Six new windows recognised. Anthropic shipped buckets we hadn’t seen before — seven_day_opus, seven_day_omelette, seven_day_oauth_apps, seven_day_cowork, plus a couple more codenames. Older versions failed to parse the response when one of these appeared, dropping the entire pill. v0.40.0 reads them all, with curated labels for the known ones and a humanised fallback (“seven_day_omelette” → “Weekly · omelette”) for the rest.
Multi-currency extras. extra_usage now respects the currency field. EUR gets “EUR”, JPY gets “JPY”. No fabricated dollar signs on European invoices.
Grouped tooltip. When the pill expands, tiers are organised by kind: Session, Weekly windows, Additional tiers, Extra usage. If there’s only one group, the layout collapses to its old single-tier form so nothing feels heavier than it needs to.

The principle

claude-view treats every inferred or derived display through a confidence-gated lens. Better to show nothing than to show something wrong. Better to admit “we don’t have a label for this codename yet” than to make up a friendly name. Better to lose a row than to confuse you about what’s running on your account.

We have a phrase in the codebase: 寧願唔顯示，都唔顯示錯嘅嘢 — better to display nothing than to display the wrong thing. It’s borrowed from how Apple handles uncertainty in surfaces like Siri and the Lock Screen: precision over recall, every time.

Under the hood

The fix is structural, not a band-aid. The OAuth handler used to be a single 574-line oauth.rs that parsed the raw API response straight into typed structs. One unknown field would break the whole response.

We split it into five focused files (mod.rs, anthropic.rs, tiers.rs, identity.rs, handlers.rs) and changed the parser shape:

utilization is now Option<f64> instead of f64. A null in any window no longer poisons the whole response.
#[serde(flatten)] extra_windows: HashMap<String, _> catches every codename Anthropic ships, known or not, without a code change.
A TierKind enum (session | window | other | extra) lets the frontend group rows correctly when new tiers appear.
humanize_id provides a fallback label for codenames we haven’t curated yet.

The frontend pill component went through the same treatment — 364 lines became 6 small files, none over 154. Backward compatibility is preserved: pre-2026-04 backends without kind/currency fields render exactly as before.

A small thing that wasn’t really small

While we were in there, we also renamed the /usage plugin command to /cv-usage. Claude Code shipped a built-in /usage that shadowed ours, making the plugin command silently unreachable. The cv- prefix matches the npm package name and lets both coexist. Update your aliases.

What’s next

Subagent attribution surfacing. Claude Code 2.1.123 added metadata tagging which subagent / skill / plugin dispatched each sidechain message. v0.40.0 baselines these new fields so the integrity check passes; the next release wires them into the session view so you can see at a glance who was driving each turn.
Mobile pairing client. The phone app to pair with claude-view (server-side scaffolding shipped in v0.39.0) is in active development.
Plan-driven sessions. Editable plan TODOs paired with plan blocks so you can drive a session from a written plan.
