The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_feature_breakdown ~60
Get per-feature cost breakdown. Shows which features (the `feature` label your code passes to wk.chat()) are the most expensive across all users. Use this for "which feature is costing me the most?" or "where should I optimize?".
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_model_recommendations ~68
Get recommendations for swapping to cheaper models. We surface features that are using expensive models for short outputs (<150 avg output tokens) where a same-provider cheaper model exists and the projected monthly saving is >=$1. Use this for "where can I cut AI cost without breaking anything?".
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_overview ~72
Get a high-level overview of AI costs, revenue, and margin for the current calendar month. Returns total spend, total revenue, net margin, request count, count of unprofitable users, combined loss in USD, and the most expensive feature. Best first call for any "how am I doing" question.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_pricing_recommendations ~65
Get per-plan pricing recommendations based on actual AI costs this month. Tells you which plans are unprofitable and what to charge to keep margins healthy. Needs at least 5 users and 30 requests this month to produce a recommendation — otherwise returns a note.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_spending_cap_url ~153
Returns the dashboard URL where the user can edit a monthly AI spending cap for a plan. This tool does NOT change any settings — it only produces a link. Caps are stored on the project and edited from a browser session, so the founder always reviews them visually. All args are optional; if provided they're echoed in the response so the user can confirm.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | – | Optional cap action. block = throw WeckrCapError; downgrade = swap to a cheaper same-provider model. |
| limitUsd | number | – | Optional monthly USD spend ceiling per user to suggest. |
| plan | string | – | Optional plan name to pre-fill, e.g. "free", "starter", "pro". |
No output schema declared.
No examples provided.
get_users ~139
Get per-user cost/revenue/margin breakdown. Sorted by margin (worst first). Use this for "which users are losing me money?" and "which users cost the most?" questions. Anonymous calls (rows with null userId) appear grouped under "(anonymous)".
| Name | Type | Req | Description |
|---|---|---|---|
| filter | string | – | Filter users by profitability status. Default: all. "unprofitable" = users costing more than they pay; "watch" = >=70% of their revenue is going to AI cost; "profitable" = healthy. |
| limit | integer | – | Max number of users to return. Default 20. Must be 1..100. |
No output schema declared.
No examples provided.
