Priority: ⚪ Not assessed Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The new Browser page teaches a copy-paste pattern that lets scraped web content break into shell commands. One example also fails validation when used alone, because it has no model configuration. The secret-protection statement overstates the guarantee for very short secret values. Fix the examples and qualify the secret statement before publishing; the navigation changes are fine. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

In `@step-types/browser.md`:
- Line 146: Update the browser instruction guidance to clarify that the
pre-browser check rejects declared secret values only when they are at least
four characters long; do not claim that referencing a secret always makes the
step fail.
- Around line 50-55: Update the standalone browser.run example to include model
configuration required by browser-step validation, using the established
DAG-level or with.llm format; alternatively, explicitly state that the example
depends on configuration from the preceding example.
- Line 45: Update the report step to pass the hn step’s stories output through
an environment variable instead of interpolating it inside a single-quoted shell
command, then print the variable with a safely quoted shell expansion.

Pass browser output through an environment variable before invoking the shell.
Dagu resolves ${steps.hn.outputs.stories} before the shell runs and does not shell-escape inserted values. A title containing ' can break the single-quoted argument and execute shell syntax.
Use an environment variable as the data channel

Add model configuration to the standalone browser.run example.
This YAML block has neither a DAG-level llm block nor with.llm. If a reader uses it as a workflow, browser-step validation rejects it before execution. Add a model configuration to this example, or state that it requires the configuration from the preceding example. (raw.githubusercontent.com)
