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 5.1 | $0.00030 | $0.00197 |
| Opus 5.5 | $0.00012 | $0.00079 |
| Sonnet 5.5 | $0.00006 | $0.00039 |
| Haiku 4.5 | $0.00003 | $0.00020 |
Grade A, and why
react-browser-verification 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 1mo 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.
What it actually says
React browser verification
Verify React changes in a real browser
Inspect component boundaries, state transitions, semantic HTML, keyboard behavior, focus handling, loading and error states, and responsive layout. Run repository-native tests and build checks, then exercise the changed route in a browser at representative viewport sizes. Check the browser console and failed network requests. Do not accept a snapshot or successful build as proof that the interaction works. Record the route, viewport, interaction, and observable result used as evidence.
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.

react-browser-verification is a skill published in the GitHub repository codysumpter-cloud/buddy-universal-agent-profile (2 stars, last pushed today), licensed Apache-2.0. It adds 30 tokens to every session and 197 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings.
