skyroc: Skill for Claude Code

.agents/skills/senior-frontend/SKILL.md

senior-frontend is a skill for Claude Code, Codex from Ohh-889/skyroc. It costs 70 tokens per session (973 once invoked), scanned A, original, MIT.

A frontend development toolkit for building web applications with React, Next.js, TypeScript, and Tailwind CSS. It includes scripts that generate components, analyse bundles, and create frontend project structures.

In plain words
What is it for?
Use it to scaffold frontend projects, generate components from templates, inspect what makes a web bundle large, and analyse or optimise modern React applications.
Why use it?
It reduces repetitive setup work and provides checks for code structure and application size. Bundle analysis helps identify performance problems and possible improvements.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is Ohh-889/skyroc's own configuration. It tells Claude Code and Codex how to work on skyroc 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 skyroc configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Privilege Escalation · line 126
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

senior-frontend 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.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/bundle_analyzer.py, scripts/component_generator.py, scripts/frontend_scaffolder.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Files

What ships with it

6 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.
