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 | $0.00877 | $0.00877 |
| Opus 5 | $0.00439 | $0.00439 |
| Sonnet 5 | $0.00175 | $0.00175 |
| Haiku 4.5 | $0.00088 | $0.00088 |
Grade A, and why
itsyconnect-macos 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 9d 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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Itsyconnect – LLM build guide
Self-hosted App Store Connect dashboard. Next.js 16, TypeScript, Tailwind v4, shadcn/ui, SQLite.
Required reading
Before writing any code, read these docs:
- docs/UI.md – typography, icons, component patterns, form conventions, layout rules. All UI must follow these conventions exactly.
- docs/BACKEND.md – architecture, security model, database schema, caching strategy, API conventions, testing. All server-side code must follow these conventions.
- docs/DB.md – database migrations, how to add tables/columns, checklist. Must read before any schema changes.
Project rules
- shadcn/ui 100% – every UI element uses shadcn. No custom primitives.
- Phosphor icons only –
@phosphor-icons/react. Never import from lucide-react. - Geist font – sans (body) and mono (code/inputs). Set globally, never override.
- Custom CSS classes over inline Tailwind – reusable styles live in
globals.css@layer components. Use.section-titlefor form headings, not ad-hoc utility classes. Add new classes there when a pattern repeats. - Sosumi for Apple docs – always use the
sosumiMCP server to search and fetch Apple developer documentation. Never guess at ASC API shapes, field names, or endpoint paths – look them up via sosumi first.
Core principles
- Security first – never expose API keys client-side. Use session tokens for browser auth, API keys server-side only. No security shortcuts.
- Test-driven – write tests before code. No untested code in production.
- No hacks – fix root causes, not symptoms. No "temporary" workarounds.
- No dead code – remove unused code immediately. Every line must serve a purpose.
- Refactor continuously – extract duplication, simplify complexity, rename for clarity. Not optional.
- No assumptions – ask if uncertain. Verify with tests. Facts over guesses.
- Research before guessing – web search for solutions before guessing at fixes, especially for platform-specific layout/rendering issues. Facts over trial-and-error.
- Revert failed changes – if a code change doesn't fix the problem, remove it completely before trying the next approach. Never leave dead or ineffective code behind.
- Clean up failed fixes immediately – if a code change aimed at fixing something has no effect, remove it completely before trying the next approach. Never accumulate layers of ineffective code.
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.
