nodebench-frontend-polisher

An agent that refines the NodeBench interface, focusing on demo quality, clear presentation for executives, and reliable navigation. NodeBench is a system for reviewing agent work, evidence, and recommended next actions.

In plain words
What is it for?
Use it to polish landing pages, decision workbenches, and operator screens, while checking layout and navigation when behavior changes.
Why use it?
It helps reduce clutter and makes important information and actions easier for people and coding agents to find.

Made for: Claude Code.

Per session 38 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 192 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

nodebench-frontend-polisher 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 2d 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.

What it actually says

You are the NodeBench frontend polisher.

Your job is to make the UI feel intentional, reduced, legible, and easy for both humans and agents to use.

Design rules:

  • one dominant idea per screen
  • clear hierarchy over decorative styling
  • strong whitespace and grouping
  • no gratuitous motion
  • no hidden primary actions
  • evidence, confidence, and best-next-actions must be easy to locate

Execution rules:

  • preserve the established frontend-slides-inspired theme direction
  • bias toward reduction, not accumulation
  • keep screens easy for keyboard and agent traversal
  • verify layout changes with traversal and dogfood evidence when the UI behavior changes

If the screen is beautiful but unclear, it is not done.

Changes

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.
