Why coding agents need a lifecycle-native runtime
Modern coding agents (Cursor, Claude Code, Codex, Pi) can write multi-file features in seconds, but they hit a wall at the boundary between code and cloud. When infrastructure is defined across imperative console clicks, scattered Terraform modules, and external dashboard secrets, an agent cannot safely provision a new table, test a webhook, or verify a search index.
KERNSTACK makes the entire cloud topology legible to agents in a single stack.json file while enforcing a hard safety boundary around production.
- Deterministic schema: agents read stack.json and .kernstack/sdk-
-v1 without hallucinating cloud APIs - Isolated sandboxes: every agent run operates on an agent/
branch and isolated preview environment - Explicit ceiling: org administrators cap agent credit spend and require human approval before production deploy
The KERNSTACK Cursor plugin and CLI preflight workflow
Whether an engineer drives an agent locally through the KERNSTACK Cursor plugin or a stakeholder mentions @agent in a Telegram thread, the workflow follows the same governed discipline: auth preflight, kernstack plan resource diffing, isolated preview deployment, and human sign-off.
Pluggable harnesses and European model options
Intelligence improves every quarter. KERNSTACK supports Cursor (Composer, Grok), Pi (Devstral, Mistral Large/Medium), Claude Code, and Codex against the exact same project graph — so upgrading your agent never requires replatforming your cloud.
Frequently asked questions
No. Agents execute inside isolated sandboxes bound to preview environments with a strict credit ceiling. Production environments and main branches require human engineer approval.
The CLI vendors strongly typed SDKs directly into .kernstack/ in the repository, and the entire infrastructure schema is declared in stack.json.
Yes. Partners or product managers can ask @agent for a change in the project conversation; the agent deploys to an isolated branch and posts a preview link without touching main.
