Setup

Overleaf Skills Setup

Walk the user through pasting a fresh overleaf_session2 cookie into ~/.claude/overleaf-skills/cookie. Cookies slide ~5 days idle; users will hit this every few days.

Step 1: Status check

Check if ~/.claude/overleaf-skills/cookie already exists. If yes, run:

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/overleaf_reviews.py --check-auth

• If OK <email>: tell user "Already configured, logged in as <email>". Ask via AskUserQuestion whether to refresh or keep.
• If FAIL: tell user the stored cookie is expired and continue to Step 2.

Step 2: Show browser guide

Tell the user to grab the cookie from their browser. Give all three branches; pick none for them:

Chrome / Edge / Brave / Arc: Cmd+Option+I (mac) or F12 → Application tab → Storage → Cookies → https://www.overleaf.com → row where Name = overleaf_session2 → double-click Value cell → Cmd+A → Cmd+C.

Firefox: F12 → Storage tab (enable in DevTools settings if hidden) → Cookies → https://www.overleaf.com → click overleaf_session2 row → right-click → Copy Value.

Safari: Enable Develop menu (Settings → Advanced → Show features for web developers), then Cmd+Option+I → Storage → Cookies → www.overleaf.com → click overleaf_session2 row → copy from right-hand detail pane.

Add three warnings at the bottom:

1. The row name is overleaf_session2 (UNDERSCORE). A row named overleaf.session2 (DOT) is a stale legacy cookie that will not authenticate.
2. The cookie is HttpOnly — document.cookie in the JS console returns empty for it. The storage panel is the only path.
3. The value should start with s%3A and be ~80+ chars. If it starts with s%3Ac%3A1%3A, you're logged out — log into overleaf.com and re-grab.

Step 3: Capture

Use AskUserQuestion: "Do you have your overleaf_session2 cookie value ready?" with options "Yes, paste it now" and "Skip for now". The user pastes via the "Other" free-text field.

Step 4: Validate

Normalize the input: strip whitespace; if it does NOT start with overleaf_session2=, prepend it (accept bare value).

Reject (re-prompt with reason):

• Starts with overleaf.session2= → "Overleaf renamed this cookie to overleaf_session2 (underscore). Re-grab the underscore row."
• Value (after the =) starts with s%3Ac%3A1%3A → "That's an anonymous-visitor cookie. Log into overleaf.com first, then re-grab."
• Value does not start with s%3A after the = → "Doesn't look like an Overleaf session cookie. Confirm you copied from the overleaf_session2 row on www.overleaf.com."
• Total length under 80 chars → "Cookie looks truncated. Re-copy with Cmd+A inside the Value cell."
• Contains newlines or quotes → "Strip the surrounding quotes/newlines."

Step 5: Write

mkdir -p ~/.claude/overleaf-skills
[ -f ~/.claude/overleaf-skills/cookie ] && cp ~/.claude/overleaf-skills/cookie ~/.claude/overleaf-skills/cookie.backup
# Write the normalized value (one line, no trailing newline beyond what's natural)
printf '%s\n' "<normalized-cookie>" > ~/.claude/overleaf-skills/cookie
chmod 600 ~/.claude/overleaf-skills/cookie

Step 6: Verify

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/overleaf_reviews.py --check-auth

• If OK <email>: report "Configured. Logged in as <email>." Done.
• If FAIL: restore from cookie.backup if it exists (mv ~/.claude/overleaf-skills/cookie.backup ~/.claude/overleaf-skills/cookie), tell user the new cookie did not authenticate, loop back to Step 2.
