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

[devin-ai-integration]

Summary

GET /api/v1/generation/content now returns a third top-level field beside input/output (openrouter-web#32990), so the skill's content-response documentation and printer were incomplete for failed generations.

 data:
   input: {...}
-  output: { completion, reasoning }
+  output: { completion, reasoning }   # completion is null when the generation failed
+  error: null | {
+    status, message, provider_name, raw,
+    previous_errors: [{ code, message, provider_name, raw }]   # earlier failed attempts, in order
+  }

error is required in the response schema and null on success. Gating is unchanged (same bearer auth, same private-logging/ZDR behavior).

Changes:

• SKILL.md — error added to "what you get back", the response-schema example (plus a failed-generation example), the content-fields table, and the "Debug a failed generation" recipe, which previously only pointed at metadata fields.
• scripts/get-generation-content.ts — pretty-print path prints an === ERROR === section (status, message, provider, previous attempts). The empty-content fallback no longer reports "ZDR" when a generation returned only a stored error.
• README.md — one-line description updated.

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
