Parse ~/.gemini/tmp/<project>/chats/session-*.json files from Gemini CLI 0.38+. Uses real token counts (input, output, cached, thoughts) embedded in each message instead of character estimation. Correctly separates cached tokens from fresh input to avoid double-charging. - Pricing for gemini-3.1-pro-preview, gemini-3-flash-preview, gemini-2.5-pro, gemini-2.5-flash from official Google API rates - Tool name normalization (ReadFile->Read, SearchText->Grep, etc.) - Menubar tab with Google Blue color (#4485F4) Closes #166 |

CodeBurn Menubar (macOS)
Native Swift + SwiftUI menubar app. The codeburn menubar surface.
Requirements
- macOS 14+ (Sonoma)
- Swift 6.0+ toolchain (bundled with Xcode 16 or standalone)
codeburnCLI installed globally (npm install -g codeburn) or available at a path you pass viaCODEBURN_BIN
Install (end users)
One command:
npx codeburn menubar
That's it. The command downloads the latest .app from GitHub Releases, drops it into ~/Applications, clears Gatekeeper quarantine, and launches it. Re-running it upgrades in place with --force, or just launches the existing copy otherwise.
If you already have the CLI installed globally (npm install -g codeburn), codeburn menubar works the same way.
Build from source
For contributors running a local build instead of the packaged release:
npm install -g codeburn # CLI the app shells out to for data
git clone https://github.com/getagentseal/codeburn.git
cd codeburn/mac
swift build -c release
.build/release/CodeBurnMenubar # launch
Build & run (dev against a local CLI checkout)
cd mac
swift build
# Point the app at your dev CLI build instead of the globally installed `codeburn`:
npm --prefix .. run build
CODEBURN_BIN="node $(pwd)/../dist/cli.js" swift run
The app registers itself as a menubar accessory (LSUIElement = true at runtime). No Dock icon.
Data source
On launch and every 60 seconds thereafter, the app spawns codeburn status --format menubar-json --no-optimize directly (argv, no shell) via CodeburnCLI.makeProcess and decodes the JSON into MenubarPayload. The manual refresh button in the footer invokes the same command without --no-optimize, which includes optimize findings but takes longer.
Override the binary via the CODEBURN_BIN environment variable (default: codeburn on PATH). The value is validated against a strict allowlist (alphanumerics plus ._/- space) before use, so a malicious env var can't inject shell commands.

Status
Live data wired. Next iterations:
- FSEvents watch for
~/.claude/projects/changes (debounced refresh on real edits) - Persistent disk cache for optimize findings so the default refresh can include them without the 30-second penalty
- Currency metadata in the JSON payload + Swift-side formatting
- Sparkle auto-update
- DMG packaging + Homebrew Cask tap
