obol-stack-front-end-dev

obol-stack-front-end-dev is a skill for Claude Code, Codex from ObolNetwork/obol-stack. It costs 52 tokens per session (928 once invoked), scanned A, original, Apache-2.0.

A local development and quality-assurance guide for the Obol Stack Next.js dashboard, a web interface for marketplace, service, agent, and cluster operations. It documents commands for running the dashboard, testing it, and connecting it to a local Kubernetes cluster.

In plain words
What is it for?
It is for developing and testing marketplace and sell/buy screens, agent cards, API routes, Playwright tests, and deployments to a k3d cluster.
Why use it?
It removes guesswork about which command and environment to use for UI-only work versus cluster-backed work. It also identifies the APIs and data sources used by the dashboard.

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

obol-stack-front-end-dev 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 today.

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.

obol-stack-front-end development (web/frontend)

Run commands from web/frontend in the obol-stack repo.

Quick commands

pnpm install
pnpm run dev:local              # localhost:3000 — no cluster
pnpm run dev                    # obol.stack:3000 + eRPC port-forward
pnpm run test && pnpm run build
pnpm run test:e2e:chromium      # mocked APIs — see e2e/README.md

Standalone vs cluster

Mode Command Cluster?
UI-only pnpm run dev:local No — shows Stack unreachable states
Full stack pnpm run dev after obol stack up Yes — /etc/hosts + kubeconfig

Cluster-backed dev

The dashboard reads the cluster via KUBECONFIG (from obol or NEXT_PUBLIC_KUBECONFIG).

Surface API / data source
Obol Services /api/services.json via MARKETPLACE_CATALOG_URL or in-cluster obol-skill-md
Sell / ServiceOffers /api/sell/* → Kubernetes API
Agents /api/agents/* — instances include listing / pendingOffer from agent-listing
Marketplace /api/marketplace/services — ERC-8004 + local catalog
x402 probe POST /api/marketplace/probe — unpaid 402 check (host allowlist)

From the Mac host when the cluster is up: http://obol.stack:8080 (Traefik). In-pod code uses *.svc.cluster.local — see src/lib/utils/cluster-url.ts.

Deploy dev image to k3d

OBOL_DEVELOPMENT=true obol stack up builds web/frontend as ghcr.io/obolnetwork/obol-stack-front-end:dev-<sha> and imports it (uncommitted changes: OBOL_FORCE_REBUILD_LOCAL_DEV_IMAGES=frontend). Faster loop, from the repo root:

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.
