Baguette is a command-line tool and web interface for controlling iOS simulators without opening Xcode or Simulator.app. Developers and agents use it to boot devices, stream screens, send touch and hardware input, inspect accessibility data and logs, and capture screenshots or recordings. The catalogue includes skills, instructions, and a plugin for operating Baguette.

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 | $0.04386 | $0.04386 |
| Opus 5 | $0.02193 | $0.02193 |
| Sonnet 5 | $0.00877 | $0.00877 |
| Haiku 4.5 | $0.00439 | $0.00439 |
Grade A, and why
baguette 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 5d 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.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
TDD is non-negotiable (read this first)
You MUST write a failing test before writing any production code. This rule overrides every other instinct, including "the change is small", "it's just a one-liner", "I'll add the test after". If you catch yourself opening a file under Sources/Baguette/ before a test under Tests/BaguetteTests/ exists and fails, stop and reverse course.
Pre-implementation gate — before editing anything in Sources/ (Domain value type, Domain abstraction, Infrastructure adapter, App-layer command), you must have done all of the following in order:
- Stated the user-facing behaviour in one sentence using domain language, not implementation language. Good: "a tap is dispatched as down → hold → up against the input surface", "describe-ui returns nil when no app is frontmost", "logs reject
noticebecause the iOS-runtimelogbinary doesn't accept it". Bad: "IndigoHIDInput calls sendMouse twice" — that's an interaction, not a behaviour. - Written a
@TestinTests/BaguetteTests/<Context>/<Suite>.swiftthat asserts the expected outcome. Prefer state assertions (#expect(filter.argv == [...]),#expect(node.frame == ...)) over interaction assertions. For@Mockableabstractions, use the auto-generatedMockXxx(given(input).tap(...).willReturn(true)); plain test doubles backed by Mockable are the canonical mocking style — never mock the value type itself. - Run the test and observed it fail —
swift test --filter "<SuiteName>"for the fastest loop. A compile error counts as red only when the failing symbol is the one the test names (KeyboardKey.from(wireCode:)doesn't exist yet); a generic build error somewhere else doesn't. - Reported the red result back to the user (one line is fine: "test
parses lowercase letter wire codes onto HID page 7fails:KeyboardKey.from is not a member").
Only after step 4 may you write code under Sources/. Pure docs / CHANGELOG edits and Resources/Web/ JS tweaks are exempt; the moment a Domain type, Infrastructure adapter, or App command changes, the gate applies.
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.

baguette CLAUDE.md is an instructions file published in the GitHub repository tddworks/baguette (1,745 stars, last pushed 6d ago), licensed Apache-2.0. It adds 4,386 tokens to every session, about $0.0219 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.
