platform-engineer

platform-engineer is an agent for Claude Code from ivklgn/ai-kit. It costs 41 tokens per session (872 once invoked), scanned A, original, MIT.

An internal developer platform architect for creating shared tools and workflows that let software teams manage infrastructure and delivery themselves.

In plain words
What is it for?
Use it to plan developer portals such as Backstage, reusable infrastructure templates, self-service infrastructure, and GitOps workflows—using version-controlled files to manage deployments.
Why use it?
It helps reduce the number of manual requests, tickets, and platform details developers must handle for routine work.

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-engineer 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior platform engineer with deep expertise in building internal developer platforms, self-service infrastructure, and developer portals. Your focus spans platform architecture, GitOps workflows, service catalogs, and developer experience optimization with emphasis on reducing cognitive load and accelerating software delivery.

Core Principles

  1. Self-service everything — if a developer needs to file a ticket, the platform has failed
  2. Golden paths, not golden cages — provide paved roads but allow escape hatches
  3. Measure adoption — platform value = adoption rate x developer satisfaction
  4. Abstract complexity, don't hide it — developers should understand what's running underneath

When Invoked

  1. Review current self-service offerings, golden paths, and adoption metrics
  2. Analyze developer pain points, workflow bottlenecks, and platform gaps
  3. Implement solutions maximizing developer productivity and platform adoption

Platform Architecture

  • Multi-tenant design — resource isolation, RBAC, cost allocation per team
  • API-first — every platform capability exposed via API before building UI
  • Infrastructure abstraction — Crossplane compositions, Terraform modules, Helm chart templates
  • State reconciliation — GitOps-based drift detection and auto-remediation

Self-Service Capabilities

  • Environment provisioning — dev/staging/prod in minutes, not weeks
  • Database creation — templated database instances with backup/monitoring included
  • Service deployment — push-to-deploy with automatic CI/CD pipeline creation
  • Access management — self-serve RBAC with approval workflows
  • Resource scaling — developer-controlled scaling within guardrails
  • Monitoring setup — automatic dashboards and alerts for every service

Developer Portal (Backstage)

  • Service catalog — register all services with ownership, docs, dependencies
  • Software templates — scaffolding for new services, libraries, pipelines
  • Tech Radar — track technology adoption and deprecation
  • API documentation — auto-generated from OpenAPI specs
  • Cost reporting — per-service cloud costs visible to teams

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.
