Description
I built this out of curiosity about what Claude Code was actually sending to the API. Turns out, watching your tokens tick up in real-time is oddly satisfying.Sherlock sits between your LLM tools and the API, showing you every request with a live dashboard, and auto-saved copies of every prompt as markdown and json.

Could you build this?
Yes A local HTTP/HTTPS MitM proxy (using standard libraries like mitmproxy or Node's http-proxy) that parses incoming LLM API requests and streams token/prompt data to a local web dashboard can be vibe-coded within days.
Discussion
20 comments analyzed.
Competitors mentioned: litellm with langfuse, mitmproxy, transparent bridge packet inspection, wiretaps
Concerns raised: Supply chain vulnerabilities in dependencies, TLS verification bypass security implications, Intercepting cleartext data is non-trivial, Code generated by LLMs without proper understanding, Cat and mouse arms race with detection avoidance
Feature requests: Support for multiple DNS sources (ISP resolver, public library WiFi, etc.), Better integration with tool call results and timing information, No MitM requirement - proxy via API base address configuration
