Weave Router Cost-Control Retainer Build (5-7 days)
A productized engagement that installs Weave Router between a client's coding agents and model providers, then hands over a routing policy and spend dashboard the agency can maintain on retainer.
- Client already runs Claude Code, Codex, or Cursor in daily development work
- API keys or flat-rate subscriptions for at least two model providers the client is willing to route across
- Read access to the client's coding-agent harness configuration and model credentials
- A named engineering owner on the client side who can approve routing policy changes
- Baseline token spend data for the prior 30 days so savings can be measured against something
- 1.Run npx @workweave/router against a staging copy of the client environment to detect Claude Code, Codex, and Cursor installs
- 2.Confirm the complexity classifier responds in single-digit milliseconds before any live traffic is considered
- 3.Inventory which model credentials the client already holds and which need to be issued
- 1.Connect the client's coding-agent harness and model credentials in a non-production workspace
- 2.Set the initial routing policy that sends routine turns to cheaper models and holds frontier models in reserve
- 3.Verify the router can read agent turns end to end without dropping a turn
- 1.Test the cache-aware cost check against the client's real prompt patterns
- 2.Confirm flat-rate subscription quota drains before any per-token spend is triggered
- 3.Log the first routing decisions and compare them against what a frontier-only run would have cost
- 1.Tune the escalation classifier so stalled or looping tasks return to frontier models quickly
- 2.Run a deliberate loop scenario to prove escalation fires without manual intervention
- 3.Document the threshold values chosen and why, so the client can audit them later
- 1.Build the usage dashboard report template showing model spend and routing decisions per project
- 2.Benchmark router quality, speed, and cost against a frontier-only baseline on the client's own tasks
- 3.Review the benchmark with the client's engineering owner and adjust the policy where the numbers disagree
- 1.Enable live traffic on one team or repository as a controlled rollout
- 2.Watch the first full working day of routing decisions and correct any misroutes
- 3.Capture the before-and-after token spend figures for the handover pack
- 1.Deliver the handoff guide with team training on reading routing decisions and changing thresholds
- 2.Agree the retainer scope: monthly policy review, dashboard refresh, and escalation tuning
- 3.Set the review cadence and the spend threshold that triggers an agency check-in
The $1,800 setup fee covers roughly 16 hours of configuration work, and the recurring cost to the agency is the $50 monthly Pro plan plus the client's own model spend. Margin comes from the retainer that follows: monthly policy review and dashboard refresh bill at a fraction of the token savings the router produces, so the client sees the fee covered by reduced frontier-model usage. Enterprise clients with security and compliance requirements move to custom pricing, which the agency can scope as a separate line.
- Configured Weave Router instance wired to the client's Claude Code, Codex, or Cursor environment
- Written routing policy documenting thresholds, escalation rules, and cache-aware cost settings
- Usage dashboard report template showing model spend and routing decisions by project
- Benchmark report comparing router quality, speed, and cost against a frontier-only baseline
- Handoff guide with team training on reading routing decisions and adjusting thresholds
The client's coding agents route live traffic through Weave Router with escalation firing on stalled tasks, and the client's engineering owner can read the dashboard and change a threshold without agency help.
