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

[devin-ai-integration]

Summary

GET /api/v1/benchmarks now also publishes OpenRouter's own search benchmarks (openrouter-web#33066), on the exact endpoint this skill teaches. The skill claimed the endpoint aggregates Artificial Analysis and Design Arena only, and its query-parameter tables omitted every new parameter, so an agent following it could neither request search results nor parse them.

Documented, in SKILL.md and references/benchmarks-api.md:

• source accepts openrouter; task_type accepts search; new benchmark_type (gpqa_diamond, tau_bench_verified_airline, search_browsecomp, search_hle, search_dsqa, search_widesearch), and the search-only include_run_config (default false), search_engine, search_surface (server-tool | plugin).
• The search item shape, whose score field is metric-tagged rather than a fixed accuracy:

{ source: "openrouter", benchmark_type: "search_widesearch",
  primary_metric: "f1_by_item" /* only WideSearch; "accuracy" otherwise */,
  primary_score: 0.72 /* 0..1 */, total_tasks, avg_cost_per_task, avg_latency_per_task_ms,
  search_engine, search_surface, last_run_timestamp,
  run_config?: { max_agent_turns, reasoning_effort, temperature } /* only when include_run_config=true */ }

• Two behaviors that are not guessable from the parameter list: any search-scoped filter suppresses the other sources, and a contradictory combination (search filter plus source=design-arena) returns an empty 200, not a 400. Search rows carry no pricing field, so the existing per-token pricing guidance is now marked AA/DA-only.

Auth and rate limits are unchanged, so those sections are untouched. Note: open PR #106 separately proposes documenting the classic source=openrouter (GPQA/tau-bench) rows; this branch is based on main and overlaps it textually on the source enum line.

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
