bundle-analysis

bundle-analysis is a skill for Claude Code, Codex from tinh2/skills-hub-registry. It costs 59 tokens per session (2,166 once invoked), scanned A, original, no licence file.

A frontend bundle analysis guide for examining the files sent to a browser by a web application. It finds large or repeated dependencies, checks whether unused code is removed, and suggests ways to split code and set size limits.

In plain words
What is it for?
Use it to inspect bundle sizes, identify heavy or duplicate dependencies, review tree-shaking, plan code splitting, and create size-budget configuration.
Why use it?
It helps explain why a web page loads slowly because its JavaScript or other browser files are too large. It points to specific code and dependency issues that add unnecessary download size.

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

bundle-analysis 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 6d 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.

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.
