Browser Testing Skills

Browser testing skills separate deterministic regression tests from visual QA, live browser inspection, screenshots, and local verification. Source: Skill Registry, 2026-09-25

When To Use This

Use this family for Playwright, screenshots, local verification, visual QA, browser automation, desktop app checks, and rendered proof.

Core Model

Executable behavior lives in skills/**/SKILL.md. This page owns family-level routing, tradeoffs, and failure modes. Exhaustive inventory lives in Skill Registry. Full retired article bodies live in Retired Skill Article Ledger.

Concept Position

Axis	Value
Family	Generated skill-family synthesis
Concept owned	Browser testing skills separate deterministic regression tests from visual QA, live browser inspection, screenshots, and local verification.
Operationalizes into	Skill Registry, Skill Resolver, executable `SKILL.md` source
Use this page when	choosing the right skill family before loading executable source

Decision Matrix

Need	Route
Use Playwright for repeatable assertions.	Load the named SKILL.md from Skill Registry and use this page for context.
Use browser-harness or agent-browser for exploratory rendered inspection.	Load the named SKILL.md from Skill Registry and use this page for context.
Keep browser automation separate from agent search or docs lookup.	Load the named SKILL.md from Skill Registry and use this page for context.

Do Not Confuse

Browser automation is not the same as localhost testing.
Agent search/retrieval is a different capability family.
