Advice on appraisal discussions

Need advice from the community.

I had my performance review with my manager last week. The broad feedback was something like this- in her mind, if I'm given any task, she knows it will be done and done well, meeting all expectations. She acknowledged that I'm sincere, hard working and don't cut any corners with my work. But will the task be done ++, she wasn't sure.

I've been moving from fighting one fire to the other and never really got a chance to settle in one project, barring one, which my boss says I truly aced. Most of my colleagues believe I've done a stellar job and deserve the top rating but I didn't get that from my manager.

My last 1:1 was almost 6 months back and all this time I never really got an indication that 'more' was expected. In fact when I was pulled into projects the only thing I was told was to 'look into this and resolve' without clear goals.

I understand this year reviews are tight at most startups but I was left wondering where this came from and what to make out of it. I'm due for another discussion next week.

Any advice on how to proceed?
