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

[devin-ai-integration]

Summary

openrouter-web #27306 flipped the media_type contract on POST /api/v1/images output: it's now present whenever the format is identifiable (including image/png), and omitted only when the format couldn't be determined. Previously it was omitted for PNG and only set for vector outputs like SVG.

• Updated the "API Response Shapes" section in SKILL.md to the new contract and added media_type to the sample response
• Updated the stale saveImage doc comment in scripts/lib.ts (behavior unchanged — extension already followed media_type when present)

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

Perry's Review

Docs-only sync: updates the media_type contract description in SKILL.md and a doc comment in lib.ts to match openrouter-web#27306's contract flip (media_type now set whenever the format is identifiable, not just for non-PNG).

Verdict: ✅ LGTM

Details

Risk: 🟢 Low

CI: all checks pending/none required; no failures

Findings: none — verified against openrouter-web commit 518f0b0457 (#27306): the response schema, route handler, and media_type contract all match the new docs. saveImage() in scripts/lib.ts is functionally unchanged (doc comment only), confirmed by diffing against the pre-PR version.

Research: cross-checked openrouter-web's image-generation response schema and image-generation route handler at the referenced PR's merge commit — the new docs accurately describe the shipped contract.

Security: no concerns — docs/comments only, no code paths changed

Test coverage: n/a — no behavior change

Unresolved threads: none
