Dashboard

• Recoloured the dashboard to a warm, neutral palette aligned with the Claude Code interface (less blue): page #161617, cards #1E1F20, lighter text #BFBFBF, plus a --raised hover layer and a dedicated --red. Switched to an elevated layering model — cards sit above the page (lighter), hover lighter still — replacing the previous inverted scheme.
• Reworked chart colours: a warm, Anthropic-leaning donut palette (clay/tan/sage/dusty-blue/...); token series are blue / coral / green / amber; chart axis & legend text use a slightly lighter shade so small labels stay legible on the dark cards.
• Chart hovers now lighten consistently (bars/series go to full opacity; the doughnut pops the hovered slice). Tooltip colour swatches are solid and borderless — removed Chart.js's default white multiKeyBackground edge. The hourly chart's legend/tooltip use a coral circle for the output line and a blue square for the turns bars.
• Legend series toggles now persist across repaints (filter changes, auto-refresh, sorting) for every chart, including per-slice visibility on the doughnut.
• Header title and gauge icon now use the lightest text colour (neutral) instead of coral. Selected model chips use a neutral background with a coral border; range / timezone tabs use a neutral selected background (no orange).
• Cost values use thousand separators (e.g. 1,050ドル.49).
• Header meta puts "Auto-refresh in 30s" on its own line, with more space before the Rescan button.
• Removed the ⚡ peak-hour markers from the hourly axis labels (they collided with the axis; peak hours are still shown by the red bars and the legend).
• Fixed a stale "Apr 2026" stat sublabel → "May 2026".

Extension

• The loading / status screen now matches the dashboard header — same gauge icon (served via a webview URI), title, and elevated-palette colours — instead of the old coral heading on a mismatched background.

Extension

• Fixed CSV export (Download CSV buttons / "Download CSV to see all" links) not working inside the VS Code webview. The dashboard iframe's sandbox was missing allow-downloads, so Chromium silently blocked the Blob download; added the token. Keeps the export client-side, so it still respects the current model/range/sort filters.
• The extension no longer pops a system browser tab when opening the dashboard — it passes the new --no-browser flag to the bundled cli.py dashboard. Running python cli.py dashboard as a script still opens the browser as before.
• Matched the webview's pre-load / behind-iframe background to the dashboard (#191A1B), removing the brief #0f1117 flash before the dashboard renders.

Scanner / CLI

• Added a --no-browser flag to cli.py dashboard to start the server without opening a browser (used by the VS Code extension; standalone CLI usage is unchanged).

Dashboard

• Show the gauge icon to the left of the header title, tinted to match the title color (var(--accent)) via a CSS mask so it tracks the accent dynamically. Served from a new GET /icon.svg route that locates resources/icon.svg in both run contexts (bundled .vsix — python/dashboard.py → ../resources/icon.svg; and standalone repo — vscode-extension/resources/icon.svg).
• Renamed the header from "Claude Code Usage Dashboard" to "Claude Code Usage".
• Fixed charts not resizing when the window is narrowed (they only adjusted on the next data refresh). Grid cards now set min-width: 0 so the container can shrink below the canvas's intrinsic width, letting Chart.js's ResizeObserver fire live. Widening already worked.
• Debounced chart resizing with Chart.js resizeDelay (150 ms) so dragging the window narrower no longer re-renders the canvases on every tick.
• Cost by Model, Recent Sessions, Cost by Project, and Cost by Project & Branch tables now reveal rows in steps — 10 → 25 → 50 — with Show more ▾ / Show less ▴ controls at the bottom right (Show less appears only once a table is expanded past the first step). Rendering is capped at 50 rows for performance; past that the footer shows a "Download CSV to see all (N)" link (N = total rows) that triggers the same export as the table's CSV button, alongside Show less (which resets to 10). Sorting re-applies to the full data set, so the visible rows always reflect the active sort; the control is hidden when a table has 10 or fewer rows. Clicking Show less also scrolls back to the top of that table.
• Styled scrollbars to match the VS Code dark UI (no arrows) via ::-webkit-scrollbar: a 21px-wide gutter with a #28292B thumb (#8B8B8D on hover) over a #121314 track. The dashboard's webview iframe doesn't inherit VS Code's --vscode-* theme variables, so the colors are set directly.
• Added a CSV export for the Cost by Model table (exportModelCSV), used by its "Download CSV to see more" link.
• Adjusted the page background to #191A1B.
• Updated the pricing footnote date to "as of May 2026".

v1.2.1 — 2026年05月29日

Extension

• Bundle the Python sources (cli.py, scanner.py, dashboard.py) inside the .vsix so the extension works standalone — the only end-user dependency is Python 3.8+ on PATH. The vscode:prepublish script copies the files from the repo root at package time, so each extension version embeds the matching Python snapshot.
• Auto-start the dashboard when the user clicks the sidebar icon (no Command Palette step needed). DashboardSidebar accepts an onShow callback wired to openDashboard(); in-flight startup coalescing on the host side keeps clicks idempotent.
• Discover cli.py in any open VS Code workspace folder — covers the "cloned the repo into c:\github\claude-usage and opened it in VS Code" case that the original monorepo-sibling fallback couldn't reach for installed extensions.
• Platform-aware error messages: missing-Python guidance now leads with the right install command (python.org installer on Windows with the "Add to PATH" reminder; brew install python on macOS; distro package manager on Linux). The Homebrew suggestion is hidden on Windows.
• Add a dedicated vscode-extension/README.md for the marketplace listing.
• Real gauge icon shipped (was a placeholder).
• 4 new install-mode tests for bundled discovery + ordering; 4 sidebar tests for the auto-start callback. Total extension test count: 74.

v1.2.0 — 2026年05月29日

Distribution

• Add a VS Code extension under vscode-extension/. Spawns the existing Python dashboard server in the background and embeds it via a webview iframe — no UI rewrite, all existing charts and filters reused. Activity-bar sidebar entry, four commands (Open Dashboard, Rescan, Restart Server, Show Logs), and two settings (pythonPath, cliPath, port). 63 tests covering Python discovery, install-mode resolution, port allocation, server lifecycle, and webview HTML/CSP. Built as .vsix, installable via scripts/install.sh / install.ps1.
• Auto-discovery: extension finds claude-usage on PATH (Homebrew users) or a sibling cli.py in the monorepo (dev). Setting overrides for both Python interpreter and CLI path.

CI

• Add .github/workflows/extension-ci.yml: clean Ubuntu, npm ci && npx tsc && npm test && npm run package, uploads the .vsix as an artifact on every push to DEV/main that touches vscode-extension/.

Dashboard

• Fix ReferenceError: cutoff is not defined in the hourly filter that blanked the entire dashboard (#73, thanks @thomasleveil)
• Fix hourly chart ignoring the range upper bound for week / month / prev-month ranges
• Fix 404 on dashboard URLs containing query strings (?range=...&models=...) so reloads and bookmarks work, with regression tests (#81, thanks @jakduch)
• Fix blank dashboard for users whose data only contains non-billable / unknown models, or rows with empty model names: COALESCE(NULLIF(model, ''), 'unknown') normalises empty-string models (in both SELECT and GROUP BY so mixed NULL + '' rows collapse to a single "unknown" group), and the default selection falls back to all models when no billable models exist (#109, thanks @HaydenHaines)
• Use ThreadingHTTPServer so a slow /api/data no longer blocks other dashboard requests (#79, thanks @jakduch)
• Add a Today range button (#112, thanks @Fruhji)

Scanner

• Fix incremental scan not updating first_timestamp when a newly discovered session's records arrive out of order (#111, thanks @Fruhji)

Project / docs

• Adopt AGENTS.md as the canonical agent guide (shared with Codex); CLAUDE.md is now a thin @AGENTS.md import
• Codify the rule that future PR merges must preserve original-author commits (merge --no-ff for full merges, cherry-pick for partial, Co-Authored-By trailers when applying hunks manually)
• Drop unused .claude/launch.json
