Pain

On SSW.Rules, we have our rule in using Playwright with AI, however, we should clearly state that Playwright MCP is relatively slow when used with AI-driven browser automation, so users will understand it is not suitable for highly time‑sensitive tasks (e.g., buying concert tickets or limited-release items).

Currently, the rule does not clearly call out this limitation. This can lead users to assume Playwright MCP is appropriate for scenarios that require near‑instant interactions, where it performs significantly slower than a human due to browser startup, DOM analysis, and decision-making latency.

Acceptance Criteria

1. The rule clearly states that Playwright MCP is slower than human interaction for time‑sensitive tasks
2. The wording sets clear expectations without discouraging appropriate non‑time‑critical use cases

Suggested wording:

⚠️ Use Playwright MCP wisely
Since the MCP is AI driven and non deterministic, t is usually slower for the tasks like grabbing sales or buying concert tickets, it has to figure things out as it goes, which makes it slower. A human is usually faster.
Bottom line: feel free to use it, just don't rely on it completely for tasks where speed matters.
