SKILL.md (original)

Review the instructions the agent will receive before you install.

From this skill's directory, run:

node scripts/phpcheck.js "https://example.com" --json

Use HTTPS for a bare hostname. The checker reads Server and X-Powered-By headers. If the version is hidden, report unknown.

Compare the reported version with current PHP security guidance. Headers can be changed and vendor backports may fix an older version, so a server-side version and package check is stronger evidence. Do not run exploit probes.

Exit codes 1 and 3 mean vulnerable and unknown, not execution failures.
