bitsocialnet Inspect Elements
Map the requested live DOM node to source using the dev-only window.__ELEMENT_SOURCE__ helper. Use an existing compatible dev server in this worktree or record ownership of one started for the task; production does not expose the helper.
Reuse a compatible session supplied by the calling task when it already owns the browser slot; use its exact name and leave its lifecycle with that caller. Otherwise open an owned session through ./scripts/pw-session.sh. Use -s=<session> on every command. The examples use inspect; substitute the actual name and URL, and skip open when reusing a session:
./scripts/pw-session.sh open inspect https://5chan.localhost/#/all
playwright-cli -s=inspect eval "window.__ELEMENT_SOURCE__?.ready ?? false"
playwright-cli -s=inspect snapshot
playwright-cli -s=inspect eval "async el => JSON.stringify(await window.__ELEMENT_SOURCE__.resolve(el))" e7
Choose e7 from the current snapshot; do not reuse a stale ref. If the helper is not ready, check window.__ELEMENT_SOURCE__?.error and allow its dev import to complete. Report persistent errors or missing helpers instead of guessing an attribution.
The result's source, componentName, and stack identify the node's file/line and React ownership. Inspect the source before editing; an attributed file is a starting point, not proof that it causes the reported behavior. For a compact trace, use window.__ELEMENT_SOURCE__.formatStack(info.stack, 5) on a resolved result.
When a snapshot ref is impractical, use resolveBySelector(selector) for a precise selector or resolveAtPoint(x, y) for viewport coordinates. If source is null, inspect useful stack frames or a nearby parent. Report an unresolved node when both are empty.
Close the exact session in cleanup only when this inspection opened it, including on resolution failure. Leave a caller-owned session open for the caller to continue and close:
./scripts/pw-session.sh close inspect
For a new session, a slot owned by another task is a reason to wait or use the wrapper's bounded wait, never to bypass the lock. Do not wait on the calling task's own session; reuse it as described above. Stop only a server this task started. Use the playwright-cli skill for session operations and profile-browsing only when performance measurement is part of the request.
