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.

Security

Grade A, and why

post-launch 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 8d 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.

The opening of the file, as written. The whole thing — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Post-Launch

Your app is live. Now keep it alive. This skill covers the ongoing lifecycle.

Crash Reporting (Set Up Before v1 Launch)

You need to know when your app crashes in the wild. Set this up before TestFlight distribution.

Option 1: Firebase Crashlytics (Recommended for Solo/Small)

Tell Claude Code:

Add Firebase Crashlytics to the project using Swift Package Manager.
Configure it in the App struct's init. Follow the Firebase iOS
setup guide. Do NOT modify the .xcodeproj file for build phases.
I'll add the build phase script in Xcode manually.

Important: Firebase requires a GoogleService-Info.plist file and a build phase script. Claude Code should create the Swift integration code, but you add the plist and build phase in Xcode manually (.pbxproj safety rule).

Option 2: Apple's Built-In Crash Reports

App Store Connect > Your App > Analytics > Crashes. No setup required, but reports are delayed (24-48 hours) and less detailed. Good enough for v1 if you don't want to add Firebase.

TestFlight Feedback Loop

Collecting Feedback

TestFlight has built-in feedback: testers take a screenshot, it prompts them to send feedback with the screenshot attached. This arrives in App Store Connect > TestFlight > Feedback.

Tell your testers (your wife, friends):

  • "If something feels wrong, screenshot it and submit feedback via TestFlight"
  • "If something crashes, just tell me what you were doing when it crashed"

Processing Feedback into Tasks

After collecting feedback, sit down with Claude:

Here's the feedback from TestFlight this week:
- [Tester] said the project list loads slowly with 20+ items
- [Tester] said the delete confirmation doesn't appear sometimes
- [Tester] said dark mode makes the progress ring hard to see

Turn these into specific, actionable tasks I can give to
Claude Code. Prioritize by severity (crashes > broken features
> visual issues > nice-to-haves).

Claude helps you triage. You take the prioritized list into Conductor.

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.
