docs(openrouter-video): sync with openrouter-web changes

[devin-ai-integration]

Summary

Video upscaling shipped as public surface on /api/v1/videos in openrouter-web#35046, and the skill did not mention it. Two request parameters (upscale_factor, creativity) and two model-capability fields of the same names are now live, and upscaling models take a different request shape than generation models.

Adds an Upscaling models section and the two parameter bullets, and extends the model-field list. Also corrects input_references[], which the skill described as image-only style guidance while the schema accepts image_url, audio_url, and video_url.

The upscale contract documented: exactly one video_url input reference, no frame_images, and duration / resolution / aspect_ratio / size / seed / generate_audio rejected because source geometry carries over.

Verified against production rather than only the diff:

$ curl .../api/v1/videos/models | jq '.data[0] | keys'   # includes upscale_factor, creativity
$ curl -X POST .../api/v1/videos -d '{"model":"google/veo-3.1","prompt":"a cat","upscale_factor":2}'
{"error":{"message":"Upscale factor 2 is not supported for this model. This model does not support upscale_factor.","code":400}}

No upscaling model is listed publicly yet, so the section is written capability-gated (applies to models whose upscale_factor / creativity fields are non-null) and stays accurate before and after a model appears.

Original prompt from Automation

You are the public skills sync pipeline. Your job is to scan PRs merged to main on OpenRouterTeam/openrouter-web in the last 24 hours, determine if any changes warrant updating the public agent skills in OpenRouterTeam/skills, and open PRs to the skills repo when updates are needed.

#``# Step 1: Identify relevant merged PRs

Clone both repos:

cd /home/ubuntu/repos/openrouter-web
git fetch origin main
git log --since='24 hours ago' --merges --first-parent origin/main --pretty=format:'%H|%s' --name-only

For each merged PR, collect the list of changed files. Only PRs that touch the paths in the mapping below are relevant. Skip bot commits (devin-ai-integration[bot], Devin AI, GitHub Actions Bot, openrouter[bot], opencode-agent[bot], OpenRouter SDK Bot, Claude, detail-app[bot], forge-the-devex-intern[bot], dependabot[bot]).

If no relevant PRs were merged, post a short message to the #devrel Slack channel (C08LQFVSC7Q) saying no skill-relevant changes were detected today, and exit.

#``# Step 2: Map changed files to affected skills

Use this mapping to determine which public skills are potentially affected:

openrouter-web paths	Affected skill(s) in OpenRouterTeam/skills
sdks/typescript/, packages/llm-interfaces/	openrouter-typescript-sdk, openrouter-agent-migration
services/cfw-*/src/routes/*analytics*, analytics query/response schemas	openrouter-analytics, openrouter-analytics-query, openrouter-analytics-schema
Generation routes, /api/v1/generation	openrouter-generations
Image generation adapters, packages/image-generation/	openrouter-images
supabase/seeds/, model schemas, /api/v1/models route	openrouter-models
OAuth/auth routes, PKCE flow code	openrouter-oauth
STT adapters, services/cfw-stt-api/, /api/v1/audio/transcriptions	openrouter-stt
TTS routes, /api/v1/audio/speech	openrouter-tts
Video adapters, /api/v1/videos	openrouter-video
