html-spec-splitter

html-spec-splitter is a skill for Claude Code, Codex from noamr/web-archeologist. It costs 44 tokens per session (674 once invoked), scanned B, original, no licence file.

A utility for splitting and joining HTML specification source files. It makes a large specification easier to read, search, and edit.

In plain words
What is it for?
Use it when examining or editing an HTML specification, especially when the source file is large.
Why use it?
Large HTML specification files can be slow and awkward to work with as one file. Splitting them reduces the difficulty of finding and changing the right part.

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 B, and why

html-spec-splitter scanned grade B with 1 finding 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (split_html.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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

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.
