Quickstart

Install ThinkThen, set your key, and ask your first question about a customer message.

1. Install ThinkThen

On macOS or Linux:

curl -fsSL https://thinkthen.dev/install.sh | sh

In Windows PowerShell:

irm https://thinkthen.dev/install.ps1 | iex

Open a new terminal, then check that it worked:

thinkthen --version

Output

thinkthen 0.2.0
Copy

Installation covers Homebrew, Cargo and downloads.

2. Set your key

ThinkThen sends each question to TypeSafe's System One service, which bills your TypeSafe account for each call. Get a key on the TypeSafe keys page, then set it in your shell:

export THINKTHEN_API_KEY='your key'

In Windows PowerShell:

$env:THINKTHEN_API_KEY = 'your key'

To use OpenAI or your own server instead, see Configuration.

3. Ask a question

Pipe in the text, and put the question in quotes:

echo 'Please refund my order.' |
  thinkthen decide 'Does the customer request a refund?'

Output

true
Copy

true means yes: the message asks for a refund. If you see usage.key-missing instead, the key isn't set in this shell.

4. Act on the answer

--check turns the answer into the exit code, so a script can branch on it. Here the answer is yes, so the script sends the message to the refunds queue:

message='Please refund my order.'
if echo "$message" |
    thinkthen decide --check \
      'Does the customer request a refund?' > /dev/null
then
  echo 'send to the refunds queue'
else
  status=$?
  case "$status" in
    1|3) ;;
    *) exit "$status" ;;
  esac
fi

Output

send to the refunds queue
Copy

In Windows PowerShell, $LASTEXITCODE holds the exit code:

'Please refund my order.' |
  thinkthen decide --check `
    'Does the customer request a refund?' > $null
if ($LASTEXITCODE -eq 0) {
  'send to the refunds queue'
}

Output

send to the refunds queue
Copy
