hard-eng: Skill for Claude Code

.agents/skills/product-walkthrough-video/SKILL.md

product-walkthrough-video is a skill for Claude Code, Codex from sgaabdu4/hard-eng. It costs 53 tokens per session (234 once invoked), scanned A, original, no licence file.

A procedure for recording polished videos of real web-product journeys with Playwright, a browser automation tool, and checking the final video from start to finish.

In plain words
What is it for?
Use it to create and verify product walkthrough videos or end-to-end video proof of a user interface flow.
Why use it?
It prevents a video from being accepted just because a recording script ran; the actual MP4 must pass journey, visual, playback, and conversion checks.

Skill for Claude CodeCodex

Written for Claude Code and Codex: disable-model-invocation in frontmatter, but also agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is sgaabdu4/hard-eng's own configuration. It tells Claude Code and Codex how to work on hard-eng 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 hard-eng 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

product-walkthrough-video 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.

The scan reads SKILL.md. This mod also ships 13 executable files (scripts/convert-mp4.mjs, scripts/review-frames.mjs, scripts/review-playback.mjs, …), 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.

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.
