Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01388 | $0.01388 |
| Opus 5 | $0.00694 | $0.00694 |
| Sonnet 5 | $0.00278 | $0.00278 |
| Haiku 4.5 | $0.00139 | $0.00139 |
Grade A, and why
AIBattery CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Battery — AI Agent Guide
macOS menu bar app showing Claude API usage at a glance. Built with Swift 6 / SwiftUI, SPM, macOS 13+.
Spec-Driven Workflow
The spec/ folder is the single source of truth.
- Spec first — describe the desired state in the relevant spec file
- Code second — update code to match the spec
- Never diverge — if you find spec/code drift, fix the spec first
- Before any push to main — ensure all spec files and
README.mdreflect the current state of the code. No merge goes out with stale docs.

spec/ARCHITECTURE.md |
App structure, data flow, project tree, build config |
spec/DATA_LAYER.md |
Models, services, algorithms, ViewModel |
spec/UI_SPEC.md |

Build & Run
swift build -c release
# Quick bundle for local smoke-testing — no codesign, no Sparkle.framework
mkdir -p .build/AIBattery.app/Contents/MacOS
cp .build/release/AIBattery .build/AIBattery.app/Contents/MacOS/
cp AIBattery/Info.plist .build/AIBattery.app/Contents/
open .build/AIBattery.app
# Full signed bundle (what CI/release actually ships): entitlements,
# Sparkle.framework, codesign, zip + dmg
./scripts/build-app.sh
Testing
# Run all tests (requires Xcode for the Swift Testing framework)
swift test
1116 tests across 72 files, using import Testing + @testable import AIBatteryCore.
The package has 3 SPM targets:
- AIBatteryCore (
.target, pathAIBattery/) — all logic: models, services, views, utilities - AIBattery (
.executableTarget, pathAIBatteryApp/) — thin@mainentry point, imports AIBatteryCore - AIBatteryCoreTests (
.testTarget) — unit tests,@testable import AIBatteryCore
CI (macos-15): build → test → verify signed bundle. Runs on push to main, and once when a PR leaves draft — not on later pushes to that PR (force a re-run via workflow_dispatch). A separate Lint job (SwiftLint + SwiftFormat) runs on every PR push touching .swift/lint-config files; run swiftformat AIBattery/ AIBatteryApp/ Tests/ and swiftlint locally before pushing to avoid a red check.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

AIBattery CLAUDE.md is an instructions file published in the GitHub repository KyleNesium/AIBattery (24 stars, last pushed 3d ago), licensed MIT. It adds 1,388 tokens to every session, about $0.0069 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
