Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. Dan Kieft (2026-08-01) describes "vibe-coding" three tools with a coding agent (Claude Code; Fable 5 or cheaper Opus 5): define the problem (his AI-film workflow had too much back-and-forth between an LLM and a generation platform), answer three questions (what, why, which features), have an LLM turn them into a master build prompt ("meta prompting"), revise it heavily, then iterate in the coding agent. Results: (1) a story/character/location "world builder" web app where users connect their own Claude API key and their Higgsfield account via MCP (so the site runs at no cost to him), which writes a structured script PDF, generates character sheets (GPT Image 2) and loca...

Dan Kieft (2026-08-01) describes "vibe-coding" three tools with a coding agent (Claude Code; Fable 5 or cheaper Opus 5): define the problem (his AI-film workflow had too much back-and-forth between an LLM and a generation platform), answer three questions (what, why, which features), have an LLM turn them into a master build prompt ("meta prompting"), revise it heavily, then iterate in the coding agent. Results: (1) a story/character/location "world builder" web app where users connect their own Claude API key and their Higgsfield account via MCP (so the site runs at no cost to him), which writes a structured script PDF, generates character sheets (GPT Image 2) and location coverage shots (cheap "Soul" model vs slower detailed GPT Image 2); (2) a free browser 3D pose-and-camera blocking tool (move camera with WASD/mouse, focal length, shot types, two posable mannequins) that outputs a reference image plus a prompt to combine with character sheets; (3) a camera-movement prompt cheat sheet that "went viral". Caveats he states: MCP-driven batch generation burns credits faster; start from a strong reference; agents may one-shot or need many revisions. Builder note: bring-your-own-key architecture shifts cost and data exposure to users; review keys/terms (C3-B358-01 on tool terms).

Curator qualifications: Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. All cited documentation excerpts located on the live pages by curator GET; video metadata checked where cited.

Limitations: Creator statements were read by discovery from auto-captions (ASR); not re-verified by the curator. Tool quality and security not inspected; tool URLs not visited.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
