bus factor = how many people it takes to cover more than half the commits (6 months). 1 is a solo project; higher means the work is spread across a team. top-author share is the single busiest author's slice of those commits.

why it's a big deal
- It is the purest expression of this issue’s thesis: there is no bespoke “video agent” here, just a general coding agent plus a folder of skills. The capability lives in instructions, not in a binary.
- It treats video production like engineering - twelve pipelines, scored provider selection, quality gates, and audit trails - so the agent works like a studio rather than a prompt-to-clip toy.
- It makes real footage, not just animated stills - the documentary pipeline builds a CLIP-searchable corpus from open archives and cuts an actual timeline, which is the line most “free AI video” stacks quietly never cross.
under the hood
- An agent-first architecture with no code orchestrator: the coding agent reads YAML pipeline manifests and Markdown stage-director skills, calls 52 Python tools, self-reviews, checkpoints state to JSON, and pauses for your approval at each creative decision.
- A three-layer knowledge stack - tools and pipeline definitions for what exists, skills for how OpenMontage wants them used, and external knowledge packs for how each provider works - with 500+ agent skills in total.
- Scored provider selection across seven dimensions over 14 video models, 10 image models, and 4 TTS engines (FLUX, Veo, Kling, WAN, Piper and more), plus pre-compose and post-render gates that run ffprobe, frame sampling, and audio analysis before you ever see a frame.

star history
- PR#37 30k 2026-07-01
- now 48k + 18k since first covered
curve is sampled from GitHub's star history, plus our own daily readings since we covered it; the dashed stretch is before we first covered it, the solid line since. figures at coverage are the numbers we printed then (approx.), current count is live.
understory
Better known than its recent output, coasting a little on attention.
- output, commits & releases
- clout, star velocity
output = commits & releases; clout = star velocity, both 0 to 100 monthly indices; the gap where output runs above clout is the understory. The understory →
