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 | $0.00103 | $0.01067 |
| Opus 5 | $0.00051 | $0.00534 |
| Sonnet 5 | $0.00021 | $0.00213 |
| Haiku 4.5 | $0.00010 | $0.00107 |
Grade A, and why
aio-browser-cookie scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
Extract cookies from local browsers and export them for use in authenticated requests. Use when extracting Chrome cookies, Firefox cookies, or Safari cookies from the local browser store; reusing a browser session to rep How it starts

Browser Cookie
Environment
- python3: !
which python3 2>/dev/null || echo "NOT INSTALLED" - rookiepy: !
python3 -c "import rookiepy" 2>/dev/null && echo "installed" || echo "NOT INSTALLED — pip3 install -U rookiepy" - Scripts: !
echo "${CLAUDE_PLUGIN_ROOT}/skills/aio-browser-cookie/scripts"
Use this skill to extract cookies from local browsers with rookiepy, export them as JSON or Netscape, or replay an authenticated request with the extracted session.
BCOOKIE="${CLAUDE_PLUGIN_ROOT}/skills/aio-browser-cookie/scripts"
Then run:
python3 "$BCOOKIE/rookie_tool.py" ...
Quick Start
# Check environment and rookiepy availability
python3 "$BCOOKIE/rookie_tool.py" doctor
# Show supported browser loaders on this machine
python3 "$BCOOKIE/rookie_tool.py" list
# Extract cookies for one browser and one domain
python3 "$BCOOKIE/rookie_tool.py" extract --browser chrome --domain github.com
# Export Netscape cookies for curl / yt-dlp / wget style tooling
python3 "$BCOOKIE/rookie_tool.py" extract \
--browser brave \
--domain github.com \
--format netscape \
--output /tmp/github.cookies
# Replay a request using the browser session
python3 "$BCOOKIE/rookie_tool.py" request \
--browser chrome \
--domain github.com \
--url https://github.com/settings/profile
Commands
| Command | Purpose |
|---|---|
doctor |
Check Python, platform, rookiepy, and available browser loaders |
list |
Print supported browser loaders on the current platform |
extract |
Load cookies and print/export them as json, netscape, or header |
request |
Send an HTTP request with cookies loaded from a browser session |
Source Selection
Use exactly one source per command:
--browser chrome--browser firefox--browser safari--path /path/to/Cookies --key-path /path/to/Local\ State- omit both
--browserand--pathto letrookiepy.load()scan all supported browsers
Supported browser names depend on platform, but commonly include:
What ships with it
1 file 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.

aio-browser-cookie is a skill published in the GitHub repository aiocean/claude-plugins (4 stars, last pushed yesterday), licensed MIT. It adds 103 tokens to every session and 1,067 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
