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 | $0.01109 | $0.01109 |
| Opus 5.5 | $0.00444 | $0.00444 |
| Sonnet 5.5 | $0.00222 | $0.00222 |
| Haiku 4.5 | $0.00111 | $0.00111 |
Grade A, and why
vibe-to-prod 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 3d 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude AI Memory - Vibe to Production
Philosophy: Critical rules embedded here. Platform-specific rules in .claude/rules/.
Core Principles
- Single Source of Truth - Edit source, not derived. OpenAPI → generates code.
- Impact Radius = Verification Radius - Change affects N systems → verify N systems.
- Make Wrong Hard - Automation, types, hooks prevent mistakes.
- Continuous Improvement - Every mistake → update rules. Every task → brief retrospective.
Before ANY Code Change
[ ] What is SOURCE vs DERIVED? (Edit source, regenerate derived)
[ ] What systems are affected? (Verify ALL of them)
[ ] Is there automation? (Check Makefile, scripts/)
Critical Rules (All Platforms)
| Rule | Why |
|---|---|
| Use generated types | Clients expect exact JSON from OpenAPI |
| Never edit generated files | PreToolUse hook blocks this automatically |
| Verify build before commit | Backend: make build, iOS: make build, Android: ./gradlew build |
Commit format: type: description |
Conventional commits |
Platform Rules (Auto-loaded by path)
Platform-specific rules load automatically when working on relevant code:
| Platform | Rule File | Trigger Path |
|---|---|---|
| Backend (Go) | .claude/rules/backend.md |
backend/** |
| iOS (Swift) | .claude/rules/ios.md |
mobile/ios/** |
| Android (Kotlin) | .claude/rules/android.md |
mobile/android/** |
| Testing | .claude/rules/testing.md |

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.

vibe-to-prod CLAUDE.md is an instructions file published in the GitHub repository muyen/vibe-to-prod (33 stars, last pushed 6mo ago), licensed MIT. It adds 1,109 tokens to every session, about $0.0044 per session on Opus 5.5. 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 2026-10-04.
