What it does
Routerbase Model Routing is an agent skill from aiskillstore/marketplace. Choose RouterBase model IDs and routing strategies for chat, image, video, audio, and embeddings workloads. Use when comparing providers, selecting GPT, Claude, Gemini, image, video, or audio models on RouterBase, designing fallback paths, checking pricing or availability, planning cost/latency/quality tradeoffs, querying the RouterBase Models API, or documenting how an app should route model requests through RouterBase.
Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/routerbase-models.md` and `skill-report.json`).
It sits in AI & LLM Engineering, covering Model routing and gateways, Embeddings and Structured output and tool calling. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Comparing providers
- Audio models on RouterBase
- Designing fallback paths
- Checking pricing
Example prompts
- “/routerbase-model-routing”
Requirements
- A credential in ROUTERBASE_API_KEY
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Classify the task modality: chat, image, video, audio, embeddings, or mixed.
- Identify hard constraints: quality target, latency budget, price ceiling, context length, tool calling, vision, JSON mode…
- Query the live RouterBase catalog when possible
- Shortlist one primary model and one or two fallback models. Prefer fallbacks with the same modality and similar capability shape.
- Check current pricing before final recommendations
- Document the decision as a table: use case, primary model, fallback model, reason, validation test, and known caveats.
What it can do on your machine
Read from SKILL.md and the folder at commit 755bc35. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
routerbase.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
ROUTERBASE_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Routerbase Model Routing loads about 964 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 112 tokens; SKILL.md has 390 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 390 words (~964 tokens).
“Use routerbase to pick and document model choices behind one API key and one OpenAI-compatible integration surface. This skill helps agents turn workload requirements into a practical model shortlist, fallback plan, and validation checklist.”
