Seven Cardinal Sins Auditor
Paste a prompt, system prompt, or CLAUDE.md. The auditor runs seven heuristic checks — model overuse, missing caching, prefix poisoning, hedge bloat, system-prompt bloat, repeated context, missing max_tokens — and returns a Grade A–F report with per-sin severity, evidence, and estimated monthly savings. No AI call, no sign-in, no Anthropic spend.

The Seven Sins
- 1. opus_overuse — Reaching for Opus when Sonnet or Haiku would do
- High-end-model gravitational pull. Heuristic detects task-type keywords (classification, extraction, summarisation) that don't need Opus reasoning.
- 2. no_caching — Large stable prefix sent without cache_control
- Any prompt over ~1024 tokens with a recognisable stable prefix should set a cache breakpoint. Heuristic measures prefix-stability heuristically.
- 3. prefix_poisoning — Volatile content placed before stable content
- Cache works left-to-right; a timestamp or user input before your stable system context invalidates everything downstream. Heuristic flags suspicious ordering.
- 4. hedge_bloat — Hedge / wordy / filler phrasing in the prompt body
- "I would like you to please consider…" patterns. Each call sends ~40–80 wasted tokens. Heuristic matches a corpus of known waste phrases.
- 5. system_prompt_bloat — System prompt exceeds ~3000 tokens
- Static-but-bloated system prompts compound across every call. Heuristic measures token budget vs threshold.
- 6. repeated_context — Same long context resent on every call (no cache or compaction)
- Conversation history grows unbounded or context is rebuilt each call. Heuristic asks for the repeated-context call count.
- 7. no_max_tokens — max_tokens unset or huge on a long-output endpoint
- Without a cap, an off-the-rails completion can burn $0.50–$5 in one call. Heuristic flags unset or unreasonable caps.
