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 | $0.00037 | $0.00460 |
| Opus 5 | $0.00018 | $0.00230 |
| Sonnet 5 | $0.00007 | $0.00092 |
| Haiku 4.5 | $0.00004 | $0.00046 |
Grade A, and why
web-agent 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
/web-agent — Web Automation Agent
Automate any web task: navigate websites, interact with UI elements, fill forms, extract data, and handle logins — all powered by Playwright.
Usage
/web-agent <task description>
/web-agent --headed <task description>
Examples
/web-agent "Go to github.com/anthropics/claude-code and extract the star count"
/web-agent "Go to news.ycombinator.com and get the top 5 story titles"
/web-agent --headed "Go to my-app.localhost:3000, log in, and check the dashboard"
/web-agent "Go to npmjs.com, search for 'playwright', and extract the weekly downloads"
What It Can Do
- Navigate to any URL
- Click buttons, links, tabs, menu items
- Fill and submit forms
- Handle login/authentication flows (asks you for credentials when needed)
- Extract text, tables, and structured data
- Take screenshots at any step
- Work with SPAs and dynamic content
- Emulate different viewports
Prerequisites
- Python 3.9+
- Playwright + Chromium:
pip install playwright && python -m playwright install chromium
How It Works
The agent delegates to a specialized web-agent subagent that:
- Navigates to the target URL
- Analyzes the page (interactive elements, text, screenshots)
- Performs actions (click, type, select)
- Verifies results via screenshots
- Iterates until the task is complete
- Returns a summary of what was accomplished

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.

web-agent is a skill published in the GitHub repository pilot617/awesome-claude-code-plugins (7 stars, last pushed 5mo ago), licensed MIT. It adds 37 tokens to every session and 460 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.
