frontend: Skill for Claude Code

.agents/skills/add-new-page/SKILL.md

add-new-page is a skill for Claude Code, Codex from blockscout/frontend. It costs 58 tokens per session (4,257 once invoked), scanned A, original, no licence file.

A scaffold for adding a new application page, such as an index, detail, or general page, with an option to connect it to API data. An API is a service that lets the page request data from another part of the application or system.

In plain words
What is it for?
Use it when adding a route, creating an index or detail page, or wiring API data into an existing unfinished page.
Why use it?
It gives new routes a consistent starting structure and supports connecting pages to data when needed. It can also finish the data connection for an already-scaffolded page marked with TODO (api-data).

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is blockscout/frontend's own configuration. It tells Claude Code and Codex how to work on frontend itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything frontend configures →

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

add-new-page 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 22d 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Files

What ships with it

11 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
