Jimeng SessionId

Obtain and return the Jimeng site's sessionid Cookie (returns the value only, does not write to a file).

Dependencies

This skill depends on Playwright MCP, requires a registered Playwright MCP service in the runtime environment, and can call the following browser tools:

browser_navigate
browser_snapshot(or similar page state reading tools)
browser_run_code
browser_close

If the above capabilities are missing, this skill cannot complete the login check and Cookie extraction process.

Playwright MCP installation example

It is recommended to explicitly specify profile(via --user-data-dir), so that the Jimeng login state can be persisted without having to log in again each time.

The following are common installation methods (choose one according to your client):

Claude Code

claude mcp add playwright npx @playwright/mcp@latest -- --user-data-dir "$HOME/.yoitao/mcp/playwright-jimeng-profile"

Codex

codex mcp add playwright npx @playwright/mcp@latest -- --user-data-dir "$HOME/.yoitao/mcp/playwright-jimeng-profile"

After installation, it is recommended to restart the client, then run this skill.

Trigger scenarios

The user requests to obtain Jimeng sessionid
Other skills (such as the image generation skill) need Jimeng authentication credentials
Existing sessionid has expired and needs to be re-fetched

Workflow

1) Open the Jimeng page

Navigate to:

https://jimeng.jianying.com/ai-tool/home

2) Check login status

If a "Log in" button appears on the page: prompt the user to complete login first, and keep the browser window open
If membership information appears on the page (such as "Basic Member" or "Premium Member"): continue to the next step

3) Read Cookies

Run the script to read Cookies:

async (page) => {
  const cookies = await page.context().cookies();
  const sessionCookie = cookies.find(
    (c) =>
      c.name === "sessionid" &&
      (c.domain.includes("jimeng.jianying.com") || c.domain.includes("jianying.com")),
  );
  return sessionCookie ? sessionCookie.value : null;
}

Note: The Cookie name is lowercase sessionid, not sessionId。

4) Return the result and clean up

Fetch successful: directly return the sessionid value
Fetch failed: return "sessionid not found, it is recommended to refresh and try again"
Finally, close the browser resources

Key parameters

Item	Value
Target site	`https://jimeng.jianying.com/ai-tool/home`
Cookie name	`sessionid`(lowercase)
Domain matching	`jimeng.jianying.com` / `jianying.com`

Notes

sessionid will expire and needs to be refreshed as needed.
If the Cookie still cannot be obtained after login is complete, refresh the page first and try again.
