gcp-to-aws

gcp-to-aws is a skill for Claude Code, Codex from awslabs/startups. It costs 320 tokens per session (9,208 once invoked), scanned A, original, Apache-2.0.

A migration guide for moving applications and AI workloads from Google Cloud Platform to Amazon Web Services. It maps comparable services, such as Cloud Run to Fargate and Cloud SQL to RDS, and can use infrastructure files, billing data, and application code.

In plain words
What is it for?
Use it to plan or carry out GCP-to-AWS migrations, including Terraform changes, database moves, container workloads, and AI or agent systems.
Why use it?
Moving between cloud providers requires translating services, infrastructure settings, costs, and application dependencies. This guide sets development-sized defaults and uses available project evidence before asking the user to repeat information.

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

gcp-to-aws 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 10d 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.

GCP-to-AWS Migration Skill

Philosophy

  • Re-platform by default: Select AWS services that match GCP workload types (e.g., Cloud Run → Fargate, Cloud SQL → RDS).
  • Extract before ask: When Terraform, billing, or app code already answers a Clarify question, resolve it with chosen_by: "extracted" and present it on the Assumption Sheet for confirmation — never re-ask it as a full question unless the user converts it ("ask me about X") or corrects it.
  • Dev sizing unless specified: Default to development-tier capacity (e.g., db.t4g.micro, single AZ). Upgrade only on user direction.
  • No human one-time migration costs: Do not present human labor, professional services, or people-time work as dollar estimates or "one-time migration cost" budget categories. Vendor charges grounded in data (for example GCP data transfer egress in the infra estimate when billing exists) are allowed.
  • Multi-signal approach: Design phase adapts based on available inputs — live gcloud discovery and/or Terraform IaC for infrastructure, billing data for service mapping, and app code for AI workload detection. When live and IaC both run, live is authoritative for current state and disagreements surface as drift, never silently resolved.
  • BigQuery / google_bigquery_*: The skill does not recommend a specific AWS analytics or warehouse service. During Clarify, if discovery shows BigQuery (IaC google_bigquery_* and/or billing rows for BigQuery), you must surface the specialist advisory before Design (see references/phases/clarify/clarify.md). Design output uses Deferred — specialist engagement; keep directing the user to their AWS account team and/or a data analytics migration partner through Design, Estimate, and docs (see references/phases/design/design-infra.md BigQuery specialist gate).

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.
