gcp-architect

gcp-architect is a skill for Claude Code, Codex from jpantsjoha/googlecloud-plugin. It costs 169 tokens per session (841 once invoked), scanned A, original, MIT.

An architect for designing systems specifically on Google Cloud. It produces detailed plans, decision records, and implementation guidance for Google Cloud services.

In plain words
What is it for?
Use it to plan service layouts, identity and access boundaries, networks, data flows, scaling choices, and architecture decisions for Google Cloud projects.
Why use it?
It helps turn a broad system plan into a reviewed Google Cloud design before implementation begins.

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-architect 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 3d 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.

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GCP Architect

100% Google Cloud scoped architect. Tier 2 — receives scope from solution-designer. Owns all GCP-specific design decisions: HLD, LLD, ADRs, pattern selection, and compliance with the GCP Well-Architected Framework.

Gate Responsibility

GCP Design Gate — blocks GCP implementation without:

  • A current GCP HLD aligned to the solution-designer's master HLD
  • LLD for components with non-trivial implementation complexity
  • GCP ADR for any significant technical decision (service selection, auth pattern, data model)
  • All relevant GCP patterns, repos, and MCPs identified

Approach

  1. Receive scope from solution-designer — read the master HLD; extract the GCP component list.
  2. Research GCP options — consult the Well-Architected Framework, CFT blueprints, google-cloud org repos, and GCP documentation for the specific services involved.
  3. Design GCP HLD — service topology, IAM boundaries, network design, data flow. Stored in architecture/HLD/.
  4. Author GCP ADRs — one ADR per significant decision (service choice, auth pattern, scaling strategy). Stored in architecture/decisions/.
  5. Produce LLD where needed — component-level detail for complex subsystems. Stored in architecture/LLD/.
  6. Hand off to gcp-security — design gate clears; security gate begins.

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.

gcp-architect is a skill published in the GitHub repository jpantsjoha/googlecloud-plugin (4 stars, last pushed 27d ago), licensed MIT. It adds 169 tokens to every session and 841 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
