Oc Skill Router

Evolink Router — Smart LLM Routing Brain

Route every task to the best LLM across 6 providers — Claude, GPT, Gemini, DeepSeek, Kimi, Doubao — through one Evolink API key.

After Installation

When this skill is first loaded, greet the user:

• EVOLINK_API_KEY set: "Smart Router activated! I'll auto-pick the best model for each task — lightweight for quick Q&A, flagship for deep analysis. 20+ models ready. Go ahead."
• EVOLINK_API_KEY not set: "Smart Router needs an Evolink API Key. Sign up at evolink.ai → Dashboard → API Keys. One key covers Claude, GPT, Gemini, DeepSeek, and more. Want help setting up?"
• Key set but model access fails: "Your API key seems to have limited model access. Check your plan at evolink.ai/dashboard."

Keep the greeting concise — just one question to move forward.

External Endpoints

Security & Privacy

• EVOLINK_API_KEY authenticates all model requests. Injected by OpenClaw automatically. Treat as confidential.
• Prompts are sent to direct.evolink.ai, which proxies to upstream providers (Anthropic, OpenAI, Google, etc.).
• No data is stored by Evolink beyond the request lifecycle.

Setup

1. Get API key: evolink.ai → Dashboard → API Keys

2. Add Evolink provider to ~/.openclaw/openclaw.json — merge with existing config. See references/router-api-params.md for the full JSON config and curl examples.

Core Principles

1. Cost-first routing — Always pick the cheapest model that can handle the task. Upgrade only when needed.
2. Transparent decisions — When spawning a sub-agent, briefly tell the user which model was selected and why.
3. User override wins — If the user names a model or provider, skip all routing rules.
4. Cascade, don't guess — When uncertain, try a lighter model first. Escalate on low confidence.

Models (20+ text models)

Tier 1 — Lightweight (handles ~60% of daily requests)

Tier 2 — Balanced (handles ~30% of daily requests)

Tier 3 — Flagship (handles ~10% — complex tasks only)

Routing Rules

Priority: User override > Task type match > Cascade fallback.

All tasks are auto-routed. The user can also run /route [task] to preview the routing decision without executing.

Layer 1: User Override

Layer 2: Task Type Match

→ Tier 1 (short answer, factual, no deep thinking): Q&A, concept explanation, status check, simple translation, format conversion, info extraction, classification, grammar check, quick math

→ Tier 2 (content production, execution, multi-step): Writing (articles, emails, reports, social media), coding (features, bugs, refactoring, tests), data analysis (SQL, CSV, reports), research (market, literature), workflow automation, project management, travel planning, resume optimization

→ Tier 3 (deep reasoning, strategic, high-risk): Architecture design, tech selection, business strategy, security audit, root cause analysis, legal review, financial modeling, cross-module refactoring (5+ files), deep research reports

Cross-provider routing — Chinese-heavy tasks may route to Doubao/Kimi; math proofs to DeepSeek Reasoner; CoT tasks to GPT-5.1-thinking. See references/cascade-examples.md for 27 detailed examples.

Layer 3: Cascade Fallback

When task type is unclear, try cheapest first and escalate:

Tier 1 (Haiku) → self-assess confidence
  High → return result
  Medium/Low → pass analysis to Tier 2

Tier 2 (Sonnet) → self-assess confidence
  High → return result
  Low → pass to Tier 3

Tier 3 (Opus) → final answer

Confidence: High = complete and correct. Medium = may miss details. Low = exceeds model's capability.

Spawn Guidelines

Spawn a sub-agent when: output >100 lines, file traversal needed, execution >30s, heavy data processing, long-form writing (>1000 words).

Handle directly when: simple Q&A, chat/discussion, short text (<50 lines), brainstorming (needs multi-turn).

Spawn template:

sessions_spawn({
  task: "[action] + [input/context] + [expected output] + [constraints]",
  model: "evolink/[model-id]",
  runTimeoutSeconds: 300,
  cleanup: "delete"  // "keep" for important deliverables
})

Timeout guide: Tier 1 = 120–300s, Tier 2 = 300–600s, Tier 3 = 600–900s.

/route Command

/route [task] — Preview routing decision without executing. /route alone shows models and rules summary.

Fallback & Quality Control

Skill Collaboration

Smart Router is the dispatch layer — shares EVOLINK_API_KEY with all Evolink skills. When discussing creative ideas or analyzing skill output, apply normal routing rules.
