Prompt engineering issues omnibus

[erik-megarad]

Issues related to prompts that are known and will be fixed will be listed in this issue. Contributions to fix these issues are welcome.

• - read_file output is usually not parsed correctly from history such that it will attempt to read the same file over and over. Consider document embedding again and maybe disabling read_file as a result.
• - Plan sent to Decider is sometimes not detailed enough to specify arguments, e.g. file contents. This causes it to sometimes use placeholders when writing files or calling other functions.
