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 | $0.02681 | $0.02681 |
| Opus 5.5 | $0.01072 | $0.01072 |
| Sonnet 5.5 | $0.00536 | $0.00536 |
| Haiku 4.5 | $0.00268 | $0.00268 |
Grade A, and why
vibecoding 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 2mo 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 — 288 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Context for Claude Code: CLAUDE.md
This file provides Claude Code with essential project context, rules, and implementation details. This is derived from the Windsurf-specific .windsurfrules.md but adapted for Claude Code workflow.
Project Overview
Vibe Coding Digest is an automated content aggregation and summarization tool that delivers curated, daily email digests of the most relevant developments in AI, developer tools, and emerging technology.
Key Components
- RSS Feed Aggregation: Multi-source content collection with concurrent processing from 29+ feeds
- External Configuration: JSON/YAML feed management with categorization and enable/disable controls
- AI Summarization: OpenAI-powered content summarization with error handling
- Email Delivery: SendGrid integration for HTML digest delivery
- AWS Blog Search: Targeted search functionality for AWS-specific content
- ATDD Test Suite: Comprehensive unit, integration, and acceptance testing with user story traceability

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.
