 ## Version Control
 
-- Use `jj` for VCS, not `git`
-- `jj tug` is an alias for `jj bookmark move --from closest_bookmark(@-) --to @-`
+- Use `jj` for version control, not `git`.
+- `jj tug` is an alias for `jj bookmark move --from closest_bookmark(@-) --to @-`.
+- Never attempt historically destructive Git commands.
+- Make small, frequent commits.
+- "Commit" means `jj commit`, not `jj desc`; `desc` stays on the same working copy.
 
 ## Scripting
 
-- Always use Nushell (`nu`) for scripting
-- Never use Python, Perl, Lua, awk, or any other scripting language
+- Use Nushell (`nu`) for scripting.
+- Do not use Python, Perl, Lua, awk, or any other scripting language. You are programatically blocked from doing so.
+
+## Workflow
+
+- Always complete the requested work.
+- If there is any ambiguity about what to do next, do NOT make a decision yourself. Stop your work and ask.
+- Do not end with “If you want me to…” or “I can…”; take the next necessary step and finish the job without waiting for additional confirmation.
+- Do not future-proof things. Stick to the original plan.
+- Do not add fallbacks or backward compatibility unless explicitly required by the user. By default, replace the previous implementation with the new one entirely.
+
+## Validation
+
+- Do not ignore failing tests or checks, even if they appear unrelated to your changes.
+- After completing and validating your work, the final step is to run the project's full validation and test commands and ensure they all pass.
