A verification skill for checking whether the Diffuse project is healthy on macOS with Xcode, Apple's development toolset. It runs formatting, tests, SDK checks, and unsigned app builds.

Use it after changing packages, apps, tools, or tests, or when checking the checkout's overall health.

It provides a repeatable final check after code changes and makes failures visible before a change is called complete.

Token cost

What it costs to keep this loaded

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	$0.00051	$0.00182
Opus 5.5	$0.00020	$0.00073
Sonnet 5.5	$0.00010	$0.00036
Haiku 4.5	$0.00005	$0.00018

Security

Grade A, and why

verify 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 yesterday.

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.

What it actually says

Verify

From the repository root on macOS with Xcode:

./Scripts/format.sh
swift test --parallel

Full gate CI uses:

./Scripts/verify.sh

A healthy checkout prints Diffuse is healthy.

Touched domain or tests? Prefer ./Scripts/coverage.sh so the llvm-cov report is fresh.

Do not skip a failing golden fixture by editing Fixtures/ until the expected diff is understood. Do not add CodeQL or other scanners.

Docker and the Dev Container cannot run this skill — they have no Xcode.

Changes

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.
