platform: Instructions file for Claude Code

CLAUDE.md

platform CLAUDE.md is an instructions file for Claude Code from ambient-code/platform. It costs 2,307 tokens per session, scanned A, original, MIT.

Project instructions for an ambient-code platform: a Kubernetes-based system that runs AI sessions in containers, with Go, Next.js, Python, and a command-line interface.

In plain words
What is it for?
Use them when modifying the platform's backend, frontend, Kubernetes controller, runners, APIs, SDKs, deployment files, or command-line tools.
Why use it?
They give coding agents the repository structure, technology context, and project conventions needed to make appropriate changes.

Instructions file for Claude Code

Written for Claude Code: PreToolUse hook event. Also seen: reads .claude/ paths; mentions Claude Code.

This is ambient-code/platform's own configuration. It tells Claude Code how to work on platform itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything platform configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

platform CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ambient Code Platform

Kubernetes-native AI automation platform that orchestrates agentic sessions through containerized microservices. Built with Go (backend, operator), NextJS + Shadcn (frontend), Python (runner), and Kubernetes CRDs.

Technical artifacts still use "vteam" for backward compatibility.

Structure

  • components/backend/ - Go REST API (Gin), manages K8s Custom Resources with multi-tenant project isolation
  • components/frontend/ - NextJS web UI for session management and monitoring
  • components/operator/ - Go Kubernetes controller, watches CRDs and creates Jobs
  • components/runners/ambient-runner/ - Python runner executing Claude Code CLI in Job pods
  • components/ambient-cli/ - Go CLI (acpctl), manages agentic sessions from the command line
  • components/public-api/ - Stateless HTTP gateway, proxies to backend (no direct K8s access)
  • components/ambient-api-server/ - Go REST API microservice (rh-trex-ai framework), PostgreSQL-backed
  • components/ambient-sdk/ - Go + Python client SDK for the platform's public REST API
  • components/open-webui-llm/ - Open WebUI LLM integration
  • components/manifests/ - Kustomize-based deployment manifests and overlays
  • e2e/ - Cypress end-to-end tests
  • docs/ - Astro Starlight documentation site
  • specs/ - Desired state of the system (sessions, agents, control-plane, integrations, standards)
  • workflows/ - Agent-consumable procedures (sessions, control-plane, integrations)
  • skills/ - Agent Skills (.claude/skills symlinks here; domain symlinks in specs/{domain}/.agents/skills)

Key Files

  • CRD definitions: components/manifests/base/crds/agenticsessions-crd.yaml, projectsettings-crd.yaml
  • Session lifecycle: components/backend/handlers/sessions.go, components/operator/internal/handlers/sessions.go
  • Auth & RBAC middleware: components/backend/handlers/middleware.go
  • K8s client init: components/operator/internal/config/config.go
  • Runner entry point: components/runners/ambient-runner/main.py
  • Route registration: components/backend/routes.go
  • Frontend API layer: components/frontend/src/services/api/, src/services/queries/

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
