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 | $0.00108 | $0.01498 |
| Opus 5.5 | $0.00043 | $0.00599 |
| Sonnet 5.5 | $0.00022 | $0.00300 |
| Haiku 4.5 | $0.00011 | $0.00150 |
Grade A, and why
agent-browser 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.
This is a copy
100% identical to agent-browser-avibebuilder-claude-prime — 140 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Browser Automation with agent-browser
Use this skill to drive websites through the agent-browser CLI. Keep the main loop tight: inspect the page, act with refs, verify the result, and only pull deeper docs when the task actually needs them.
Core workflow
Prefer agent-browser directly for speed. Use npx agent-browser only if it is not installed globally.
For most tasks, follow this loop:
- Open the page
- Wait for the relevant state
- Snapshot with refs
- Interact using those refs
- Re-snapshot after page or DOM changes
- Verify the outcome
- Close the session when done
agent-browser open https://example.com/form
agent-browser wait --load networkidle
agent-browser snapshot -i
# Output: @e1 [input type="email"], @e2 [input type="password"], @e3 [button] "Submit"
agent-browser fill @e1 "[email protected]"
agent-browser fill @e2 "password123"
agent-browser click @e3
agent-browser wait --load networkidle
agent-browser snapshot -i
Chain commands with && only when you do not need to inspect intermediate output. Good: open && wait && screenshot. Bad: snapshot && click when you still need to read the refs from the snapshot.
Route fast
Read only the reference that matches the task:
| Need | Read |
|---|---|
| Full command or flag lookup | references/commands.md |
| Ref lifecycle, stale refs, snapshot strategy | references/snapshot-refs.md |
| Login flows, OAuth, 2FA, saved auth state | references/authentication.md |
| Parallel sessions, state reuse, cleanup | references/session-management.md |
| Recording, profiling, local files, config, iOS, security | references/advanced-usage.md |
| Proxy setup | references/proxy-support.md |
| Recording workflows | references/video-recording.md |
| Profiling workflows | references/profiling.md |
What ships with it

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.

agent-browser is a skill published in the GitHub repository avibebuilder/claude-prime (120 stars, last pushed 5mo ago), licensed MIT. It adds 108 tokens to every session and 1,498 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to agent-browser-avibebuilder-claude-prime, differing in 140 lines, and is treated as a copy.
