Context in the first four requests/prompt wasn't be completely loaded, so I dealt
with various hallucinations, so I stopped to controll my feelings during composing prompts.
I should allways use these preparation prompts:
 - "what does current project doing in brief" (project needs to be freshly pulled and indexed)
 - "what about used stack and used libraries?"
Also adding context "@web" to read documentation, adding names of libraries in prompts and aksing about them gives great result!
