description	Update per-token pricing for one or more providers in src/lib/models/*.ts. Trigger when the user says prices changed, a new model is out, cost numbers look wrong, or "refresh pricing for X". For a full autonomous pass across a provider, spawn the pricing-researcher subagent instead.

Update Pricing

Pricing lives in src/lib/models/<provider>.ts as ModelDefinition[]. The gateway reports $0 for unknown models — so out-of-date files quietly under-report cost.

Step 0: Gather info

• Provider — id matches filename (e.g. groq → src/lib/models/groq.ts)
• Changes — specific model ids + new prices, OR "refresh all" (use the pricing-researcher agent for the latter)
• Source URL — official pricing page

Step 1: Read current state

Read src/lib/models/<id>.ts

Note existing entries. Never blow away the file.

Step 2: Apply updates

Use Edit with a narrow old_string/new_string per model. Preserve:

• Model order
• contextWindow, capabilities, description
• deprecated: true flags

Convert units correctly: a page quoting "$X per 1K" → X * 1000 in inputPricePer1M. Cached input rates go in a code comment, NOT in the primary price field.

Step 3: Add new models

Append to the array with the same field order as existing entries. Every new model needs id, name, inputPricePer1M, outputPricePer1M. Prefer adding contextWindow and capabilities if documented.

Step 4: Retire old models

Do NOT delete — mark deprecated: true. Historical request_logs may still reference the id.

Step 5: Verify

bun run check-types
bun test tests/pricing.test.ts

Then spot-check by computing cost for a known prompt:

curl -s http://localhost:4000/v1/chat/completions \
  -H "Authorization: Bearer sk-smnd-..." \
  -d '{"model":"<provider>/<model>","messages":[{"role":"user","content":"hi"}]}' \
  -D - | grep X-Summoned-Cost-USD

Rules

• Every price must be traceable to a URL. Paste the source URL into the PR description (not the code).
• Don't change a price by >20% without explicit source confirmation — that's usually a units error.
• Don't touch provider adapters, env, or the registry.
• If the models file doesn't exist (new provider), create it and wire into src/lib/models/index.ts — but that path really belongs to the add-provider skill.
