The cost of reusing project context across AI tools
When several AI tools such as ChatGPT, Claude, and Hermes are used on the same project, they do not automatically share what each one already knows. The same project background, goals, file details, and decisions must be given again in each tool. A practical workaround is to keep a per-project pile of markdown files and point each new conversation to those files so the tool can start with the needed context.
Some tools have been tried, but the results have been uneven. The main options are a pasted everywhere, each tool’s , a separate layer, or accepting the repeated explanation cost.
Key points
- Different AI tools do not automatically share memory with each other.
- Repeating the same wastes time and tokens.
- A can make cross-tool work more consistent.
- may help, but results are still mixed.
- Keeping context short and up to date is part of controlling AI agent cost.
