Platform Cost Optimization Agent¶
Target
This page describes intended behaviour or structure. No implementation is claimed unless a section is explicitly marked Current implementation or Evidence.
Design status 2026-10-09 (design plan A2)
This agent is a Target asset of the Software Factory pack, modelled in model/agents/operations/platform-cost-optimization.yaml and rendered in the agents catalog. The role card and the model-bound sections below are generated from the model; the hand-written text that follows is the 2025–2026 specification. Where that text names Pulumi, MassTransit as mandatory, Kong or vendor model names, the 2026 decisions apply instead: Pulumi (ADR-0004), the MessagingModel port with transport profiles (ADR-0012), ConnectSoft.ApiGatewayTemplate, and model profiles (D16, D32). Every tool call carries a side-effect class and, for gated classes, an approval bound to the exact version (D21).

Model-bound design (2026-10-09)¶
Purpose. Reads FinOps projections and capacity data, finds waste and proposes profile, pool and configuration changes with expected effect.
Responsibilities. - Cost attribution review - Savings proposals with effect - Budget threshold advice
Collaboration. slo-sla-compliance, analytics
Evaluation. Suite operations-core-v1 with gates instruction-compliance ≥ 0.95, structured-output ≥ 0.995 (D32); a release of this agent passes the suite and the baseline rule before publication (ADR-0021).
Lifecycle. Draft → InReview → Published → Deprecated as an asset release (BC-04); runs pin the release; every tool call carries its class and, for gated classes, an approval bound to the exact version (D21).
Current implementation. A 43-line June-2026 stub; designed here.

| Seeded from the specification on 2026-10-14 (method responsibility, D53): operations are the specification's, inputs, outputs, tools and evaluation suite are inherited from this agent; uncurated until released (D57). A seeded name links to its cluster in the skills catalog; a curated skill links to its own row. |

Target
This page describes intended behaviour or structure. No implementation is claimed unless a section is explicitly marked Current implementation or Evidence.
Filled 2026-10-09
This page was empty. The earlier AgentKit experiment (not a Factory asset, D19) lists connectsoft-platform-cost-optimization with status target, cluster uncategorized and no bound skills. The role appears in several folded extension roadmaps (Control, Agent runtime, Execution, Trust & Operations) as a "cost optimizer agent"; this page is its single specification. The user confirmed on 2026-10-09 that the role stays in the Software Factory pack (decision D20).
Purpose¶
Turn attributed usage and cost signals into reviewable recommendations: model-profile changes within constraints, routing and caching changes, infrastructure right-sizing, SKU changes, deprecation of low-value workflows. It never applies changes itself; every recommendation is a proposal with evidence.
Inputs and outputs¶
| Input | Output |
|---|---|
| Usage records (estimated / reserved / observed / reconciled / uncertain) from Usage Accounting; budget policy; regression results for candidate profiles; infrastructure cost telemetry | Recommendation records with expected saving, confidence, risk, affected scope, the regression evidence that quality is preserved, and the approval the change requires |
Required skills and tools (to be bound)¶
Skills: FinOps analysis, model-profile evaluation, infrastructure cost analysis. Tools: read-only usage and telemetry queries; evaluation harness runs. No write tools.
Guardrails¶
Cost optimizations that would move a confidential workload to an external provider or lower a profile below its declared capabilities are prohibited by policy (tool policies); a recommendation that degrades task success is not an improvement (evaluation).
Current implementation¶
No usage capture, reservation or reconciliation exists for the Factory (FinOps); the agent has no prompt, skill or run.
