Anonymous. No account, no email.
Several large embedded documentation blocks have been removed from the system prompt and likely externalized:
- Claude API cURL/HTTP documentation (~220 lines)
- Claude API Python documentation (~420 lines)
- Streaming TypeScript documentation (~178 lines)
- Prompt Caching documentation (~171 lines)
- Tool Use Concepts documentation (~287 lines)
- TypeScript API documentation (~333 lines)
This reduces the token footprint of the system prompt. The documentation content is now served from external skill files or live documentation sources.
Evidence
Removed documentation blocks (search for "# Claude API — cURL", "# Claude API — Python")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
