You have joined an organization as an Agile Coach. You have a certain understanding of why you're here. Everybody in fact has a certain understanding of why you're here. Problem: they are all different.
Sit (or stand up) with the main person whom you will be coaching (or whose team you will be coaching), as well as her manager. The 3 of you, write down an Agile CoachingContract¹.
Contracts in general are to be handled with caution. They tend to limit your options before you know which is best, and they may spoil the collaboration between the parties. These are the main reasons why the Agile Manifesto itself suggests you should be careful with contracts.
But done well, an Agile Coaching Contract can be useful in a number of ways.
I recommend using a simple, lightweight format. I also recommend you are careful the meeting where you write the contract itself keeps a "light touch" because you may be setting the tone of that relationship moving forward.
Writing an Agile Coaching Contract felt like an awkward idea at first, but overtime I realized that:
The other thing that could arguably happen (but that never happened to me or anyone I know) is that while trying to write down the CoachingContract, you realize that your expectations, the expectations of the person you would coach and/or the expectations of that person's manager cannot be reconciled. While this might be a painful experience for one or all of the parties, this again should be seen as a positive outcome because you will have made that problem obvious before things got more complicated.
What did happen to me and some agile coaches I know quite a few times though, is that we would start coaching without a contract, thinking "this time we won't need it"; and several weeks later, we would already regret making that decision.
