Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00008 | $0.00106 |
| Opus 5 | $0.00004 | $0.00053 |
| Sonnet 5 | $0.00002 | $0.00021 |
| Haiku 4.5 | $0.00001 | $0.00011 |
Grade A, and why
develop-extension 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 yesterday.
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 it actually says
Execute the skill at ~/.claude/plugins/chrome-ext-toolkit/skills/develop or ~/.claude/plugins/cache/masayan-uni-plugins/chrome-ext-toolkit/skills/develop to develop a Chrome extension.
This skill supports:
- New Chrome extension development
- Competitor research and requirements definition
- Store submission assets (descriptions, image specs)
Usage: Describe the extension you want to build or provide requirements.
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.
