Project-specific instructions for PetSwipe, a full-stack pet-adoption application with a Next.js website, Express server, database layer, and deployment infrastructure.

In plain words
What is it for?
Use it when changing the PetSwipe website, server, Kubernetes deployment files, Terraform infrastructure, scripts, or project documentation.
Why use it?
It gives the coding agent the project’s structure, working rules, and important commands before changes are made. This helps avoid editing the wrong area or overlooking related documentation and deployment concerns.

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

PetSwipe-Match-App 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 9d 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.

PetSwipe Claude Code Memory

Purpose

PetSwipe is a full-stack pet adoption application with:

  • a Next.js frontend in frontend/
  • an Express + TypeORM backend in backend/
  • Kubernetes manifests in k8s/
  • Terraform infrastructure in terraform/
  • deployment and operations scripts in scripts/
  • major operator docs in README.md, ARCHITECTURE.md, docs/DEPLOYMENT.md, docs/DEVOPS_GUIDE.md, k8s/README.md, and terraform/README.md

Use this file for always-on project context. Use project skills in .claude/skills/ for larger workflows.

Working Style

  • Inspect the affected area before editing. Do not assume the repo still matches older architectural descriptions.
  • Keep changes scoped. Do not "clean up" unrelated files unless the user asked.
  • When product behavior, deployment behavior, or user-visible surfaces change, update the relevant docs in the same task.
  • Prefer targeted validation over broad repo-wide commands when the repo has known pre-existing issues.
  • Be explicit when a failure is caused by existing repo debt rather than the current change.

Repo Map

  • frontend/pages/ is the main UI surface. This repo uses the Next.js Pages Router, not the App Router.
  • frontend/components/ contains shared UI including Navbar, Layout, the shared chart wrapper, and shadcn-style UI primitives.
  • backend/src/routes/, controllers/, entities/, and services/ are the main backend touchpoints.
  • backend/src/app.ts defines API routes, health endpoints, and Swagger/OpenAPI exposure.
  • k8s/base/ contains the default Kubernetes stack and k8s/overlays/production/ contains the production overlay.
  • terraform/ contains the AWS-oriented IaC stack plus optional Vault/Consul/Nomad modules.

Commands That Matter

Frontend

  • Dev: cd frontend && npm run dev
  • Build: cd frontend && npm run build
  • Start: cd frontend && npm run start
  • Prefer targeted linting: cd frontend && npx eslint <touched files>

frontend/package.json still defines npm run lint as next lint, but targeted npx eslint has been more reliable for incremental validation in this repo.

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.
