About this skill

LLM Gateway Cost & Governance Desk

Overview

Kelly LLM Gateway is a Busabase Cloud App-in-Skill. Its canonical product surface is the AirApp in Busabase, not a separate local-data product. The same Hono source supports an explicitly requested local preview with OAuth connection bootstrap. It gives a platform team an operator dashboard over a shared LLM gateway: several consuming services (e.g. Support Bot, Search Ranking, Content Summarizer, Internal Copilot) routed through one gateway to a mix of internal and external models. It aggregates per-service/per-model call volume, cost, and error rate: an Overview (spend trend, rollout/anomaly summaries), a Cost Breakdown table, a Canary Rollout status board, and an Anomaly list.

This is deliberately generic and brand-free: no real company, product, or model name appears anywhere in the code, config, or seed data — only role-based service names ("Support Bot") and generic provider/model labels ("Provider A / Model Large", "Internal Model v2").

This is a direct-manipulation operator dashboard, not a review-then-approve queue: there is no AI-authored draft to approve and no separate execute/ decisions step. Anomalies are computed by a documented, deterministic rule-based function (content/kelly-llm-gateway-app/app/js/gateway-model.js, ported from the retired content/kelly-llm-gateway-app/server/anomalies.ts); the human platform operator makes every promote/ rollback/hold and acknowledgement decision directly in the UI, writing straight onto the route's own Busabase record — the same way kelly-lead-funnel's kanban stage moves work.

Default behavior is AirApp-first. Unless the user explicitly asks only for explanation, give the user the clickable AirApp URL. Start localhost only when local preview/debugging is explicitly requested; it uses the same Busabase resources and never offers another data provider. Use chat-only mode only when the user says "纯聊天", "chat only", "不要打开 UI", or similar.

Mandatory Dependencies

  1. Read and follow $kelly-app-skill-creator for product behavior, visual quality, responsive layout, and the complete canonical content/kelly-llm-gateway-app/ artifact.
  2. Read and follow $busabase for connection, target Space, node discovery, ChangeRequests, review, and merge behavior.
  3. Read and follow $busabase-app-creator for resource modeling, AirApp runtime limits, security, validation, and deployment.

If a dependency is unavailable, preserve this skill's artifact and product contracts, stop before the unavailable Busabase operation, and report the exact missing dependency. Do not invent a second data backend.

Boundary

  • Deterministic, rule-based anomaly detection only (content/kelly-llm-gateway-app/app/js/gateway-model.js). NEVER call an LLM to detect, rank, or auto-resolve an anomaly.
  • The AirApp reads and writes its own Busabase Bases only; it never calls a live gateway API or touches a real routing config. There is no execution/ merge step beyond the direct write itself — a human still applies the decision in the real system of record.
  • Routes/services/models are never created by the AirApp; they enter Busabase through an external process (a future gateway usage-API adapter), the same way kelly-lead-funnel's leads enter through an upstream sourcing process the app doesn't control. The AirApp only ever updates an existing route's rollout status or anomaly-ack fields.
  • Generic, brand-neutral tool: never hardcode or reference a specific real company, gateway, or model name in code, templates, or docs.
  • Treat cost/usage data as sensitive. Never commit a local credential file or Busabase secrets.

Busabase Resources

Four Bases under one application Folder (kelly-llm-gateway), declared in content/kelly-llm-gateway-app/app/js/config.js and the generated template sidecars under content/:

  • routes: one row per service→model route — canary status, canary-pct, rollback-ready, a human decision note, a 14-day daily usage series (JSON array of {date, calls, cost, errors}), and per-anomaly-kind acknowledgement state (cost-spike-ack/error-spike-ack, JSON or empty). Today's totals and each route's own rolling cost/error baseline are never stored — they are pure/derived from daily and recomputed on every read.
  • services: one row per consuming service routed through the gateway.
  • models: one row per backing model/provider behind the gateway.
  • settings: sanitized config (base currency, anomaly thresholds, non-secret gateway region/base URL/credential-env-var name), one row keyed by kind.

Resources provision lazily through an idempotent Busabase ChangeRequest the first time the app runs in a Space; see references/gateway-schema.md for exact field shapes.

Anomaly Detection

content/kelly-llm-gateway-app/app/js/gateway-model.js (computeAnomalies) flags a cost spike and/or an error spike per route by comparing today's cost/error_rate against that route's own rolling baseline (mean of the preceding days in daily, excluding today). Default thresholds: cost_spike_threshold_pct: 50, error_spike_threshold_pct: 100 (i.e. cost ≥1.5x baseline, or error rate ≥2x baseline), each overridable via the settings Base. Severity is high at 2x the threshold, otherwise watch. No randomness, no ML — the same snapshot always produces the same anomalies.

Direct Rollout & Anomaly Actions

All human actions write straight onto the route's own Busabase record through busabase-sdk, exactly like kelly-lead-funnel's kanban stage moves — there is no approval queue and no separate decisions bucket:

  • Promote: sets status: stable, canary-pct: 100, rollback-ready: false.
  • Rollback: sets status: rollback, rollback-ready: false.
  • Hold: sets status: hold only.
  • Acknowledge an anomaly: writes {note, acknowledged_at} onto the route's cost-spike-ack or error-spike-ack field, whichever the anomaly's kind refers to.

From a standalone local preview the write merges immediately (trusted operator); from the deployed AirApp it creates a pending ChangeRequest for the trusted process to merge, per the AirApp boundary in $busabase-app-creator.

Demo Mode

  • ?demo=1 opens a deterministic, fully offline mock gateway (4 services, 5 models, 8 service/model routes, 14 days of history) with computed spend trend, rollout status, and anomalies for documentation and screenshots.
  • ?demo=spend, ?demo=rollouts, and ?demo=anomalies select named mock scenes (their initial route).
  • lang=en or lang=zh forces UI chrome language for screenshots.
  • Demo mode never reads or writes Busabase and never claims a real connection; demo rollout/ack actions only update the in-memory snapshot already rendered in the browser tab, never Busabase.

UI language: support English and Chinese chrome with Auto default.

Local App

Default behavior is AirApp-first — give the user the clickable AirApp URL. Start pnpm --dir content/kelly-llm-gateway-app dev only when local preview/debugging is explicitly requested.

Views

  • #/overview: total daily spend trend (14 days), a canary-rollout summary, and a top anomalies preview.
  • #/spend: sortable service × model cost-breakdown table (calls, cost, error rate, canary %, status).
  • #/rollouts: canary rollout status board — canary %, rollback readiness, and promote to 100% / rollback / hold actions with a note.
  • #/anomalies: cost/error anomalies vs each route's own rolling baseline, with acknowledgement.
  • #/settings: sanitized setup summary — data provider, config path, gateway region/base URL, credential env var name, and onboarding state. Never expose secret values.

Completion Criteria

Finish only when:

  • the skill contains the complete canonical content/kelly-llm-gateway-app/ project and pnpm --dir content/kelly-llm-gateway-app dev remains supported;
  • all persistent config, state, and domain data use busabase-sdk and the declared resource map — no local JSON, browser storage, or provider choice;
  • Vault values and API credentials never reach browser-visible surfaces;
  • local setup offers Cloud/custom URL OAuth plus the explicit Demo path, while a deployed AirApp uses its ambient session;
  • Overview, Cost Breakdown, Rollouts, Anomalies, and Help & Settings render on desktop and phone widths;
  • pnpm --dir content/kelly-llm-gateway-app run check and node --test pass.

Stop Conditions

Stop before consequential Busabase mutation when the target Space is ambiguous, the current user lacks permission, or a same-slug resource is not application-owned. Never call a live gateway API or change a real routing config from the AirApp.
