What it does

Setup is an agent skill from fcakyon/claude-codex-settings. This skill should be used when user asks to "set up overleaf", "configure overleaf cookie", "overleaf auth failed", "overleaf 401", "overleaf session expired", "overleaf unauthorized", or needs to install or refresh their Overleaf session cookie for the overleaf-skills plugin.

Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Documents & Office, covering LaTeX. The repository describes itself as: Battle-tested Claude Code, OpenAI Codex, Cursor configs, plugins, hooks and agents with Kimi, MiniMax and GLM API support. The licence is Apache-2.0.

When your agent uses it

  • Asks to set up overleaf
  • Configure overleaf cookie
  • Overleaf auth failed
  • Overleaf session expired

Example prompts

  • “set up overleaf”
  • “configure overleaf cookie”
  • “overleaf auth failed”
  • “/setup”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Status check
  2. Show browser guide
  3. Capture
  4. Validate
  5. Write
  6. Verify

What it can do on your machine

Read from SKILL.md and the folder at commit a035b4e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • overleaf.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Setup loads about 965 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 402 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~965

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
This skill should be used when user asks to "set up overleaf", "configure overleaf cookie", "overleaf auth failed", "overleaf 401", "overleaf session expired", "overleaf unauthorized", or needs to install or refresh their Overleaf session cookie for the overleaf-skills plugin.

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:

bash
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.
Show full SKILL.md (172 more words)Show less

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

bash
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

bash
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.
