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 | $0.00098 | $0.01667 |
| Opus 5 | $0.00049 | $0.00834 |
| Sonnet 5 | $0.00020 | $0.00333 |
| Haiku 4.5 | $0.00010 | $0.00167 |
Grade A, and why
thinkbrowse-cli 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.
How it starts
The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ThinkBrowse CLI
Control real browsers from Claude Code using the thinkbrowse CLI. Two modes:
- Local mode — drives your actual Chrome via the ThinkBrowse extension (free, auth cookies available)
- Cloud mode — provisions isolated Playwright browsers on Fly.io (credits, headless, stealth)
Quick Start
# Local mode — list tabs, attach, navigate, observe
thinkbrowse tabs
thinkbrowse attach <tabId>
thinkbrowse navigate "https://example.com"
thinkbrowse snapshot # accessibility tree (best for AI)
thinkbrowse screenshot --output /tmp/page.png
# Cloud mode — create session, navigate, observe, clean up
thinkbrowse cloud start "https://example.com"
thinkbrowse snapshot
thinkbrowse screenshot --output /tmp/page.png
thinkbrowse cloud stop --all
Mode Detection
| Signal | Mode |
|---|---|
| Bridge running + extension connected | Local |
THINKBROWSE_API_KEY set |
Cloud |
| Neither | Error |
Priority: --tab flag > THINKBROWSE_TAB_ID env > working-location.json > API key (cloud).
Top 5 Patterns
1. Navigate and Observe
thinkbrowse navigate "https://example.com"
sleep 2 # Wait for page load + CSRF tokens
thinkbrowse snapshot # Read structure before interacting
thinkbrowse screenshot --output /tmp/page.png
# Then use Read tool on /tmp/page.png to view it
2. Click by Text Content (RECOMMENDED)
Direct CSS selectors often fail when elements lack unique selectors. Use evaluate:
thinkbrowse evaluate "[...document.querySelectorAll('button,a,[role=button]')].find(el=>el.textContent.trim()==='Sign In')?.click()"
sleep 1
3. Fill React Forms
# React inputs need keyboard events — use `type`, NOT `fill`
thinkbrowse click "input[type=email]"
thinkbrowse type "input[type=email]" "[email protected]"
thinkbrowse click "input[type=password]"
thinkbrowse type "input[type=password]" "password123"
thinkbrowse click "button[type=submit]"
sleep 3
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

thinkbrowse-cli is a skill published in the GitHub repository dundas/thinkrun (1 stars, last pushed 1mo ago), licensed MIT. It adds 98 tokens to every session and 1,667 once invoked, about $0.0005 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.
