Costory skills for AI assistants

Skills are markdown files that teach an AI assistant how to run a FinOps workflow on top of the Costory MCP tools: which tool to call first, in what order, and what to check before a write. Each skill covers one class of question, so the assistant does not have to rediscover the sequence every time. The skills are open source (Apache-2.0) in costory-io/costory-finops-mcp-skills. The hosted MCP serves the same files through get_skill, using the skill ID in the table below.

Skills in the repository

Skill ID	Use it when
`query`	You explore cost, usage, metric, formula, budget or external-metric data and compare periods in Explorer.
`cost-change-investigation`	You explain a cost change with contribution, timing, usage, metric, event, alert and terminology evidence.
`virtual-dimensions`	You create, edit, preview and publish custom cost axes with ordered CEL rules.
`dashboards`	You create or extend dashboards, with widgets that inherit the dashboard period, group-by and filters.
`reports`	You schedule Slack, Teams or email reports, or explain last month’s cost with a Digest preview.
`bigquery`	You investigate BigQuery cost drivers (on-demand vs slots, physical vs logical storage, labels) or open the BigQuery dashboard template.
`recipes`	You state an outcome instead of a tool. The skill picks a ready-made tracking design, then hands off to the skills above to build it.

The recipes library covers BigQuery warehouse routing, Google Cloud spend-based CUDs, budget vs actual dashboards, EC2 spike alerts, prod vs R&D splits, untagged coverage, marketplace spend, provider credits, Kubernetes namespace cost, compute drill-downs and period-change explanations. For Kiro, the repository also ships costory-finops, a condensed skill that covers organization selection, tool order and preview-then-confirm for write tools, and loads the detailed skills with get_skill.
