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 | $0.00038 | $0.00330 |
| Opus 5 | $0.00019 | $0.00165 |
| Sonnet 5 | $0.00008 | $0.00066 |
| Haiku 4.5 | $0.00004 | $0.00033 |
Grade A, and why
browser-mode 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 2d 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
browser-mode
Choose how web-interact connects to the browser.
Usage
# Show current browser mode
web-interact browser-mode
# Let the CLI decide (default)
web-interact browser-mode auto
# Connect to your running Chrome/Edge
web-interact browser-mode real
# Use a managed browser with persistent profile
web-interact browser-mode sandbox
Modes
| Mode | What it does | Best for |
|---|---|---|
auto |
CLI decides — launches managed browser with system Chrome/Edge | General use (default) |
real |
Connects to your already-running browser | Using existing logins, cookies, extensions |
sandbox |
Launches isolated managed browser, profile saved in ~/.web-interact/ |
Clean automation, testing |
Notes
realmode requires Chrome/Edge to be running with remote debugging enabled, or discoverable via DevToolsActivePort.sandboxprofile persists across sessions in~/.web-interact/browsers/— cookies and localStorage survive restarts.- Setting is saved to
~/.web-interact/browser-modeand persists until changed. - Per-command override:
--own-browseror--connect [URL]flags override the saved mode.
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.

browser-mode is a skill published in the GitHub repository johnkozaris/web-interact-plugin (2 stars, last pushed 5mo ago), licensed MIT. It adds 38 tokens to every session and 330 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
