+## Testing
+
+- Use `cargo test` to run all tests in this workspace
+- To run the full suite of tests CI will run, see `scripts/ci-local.py`.
+- Before commiting run `cargo fmt` and `cargo clippy`, as well as `cd decoder && cargo fmt && cargo clippy`. YOU MUST FIX CLIPPY ERRORS.
+  
+## Finishing Up
+When instructed to "finish up", follow this process:
+
+1. Run `cargo +nightly fmt --all` to format all code
+2. Run `cargo clippy --workspace --all-features -- -D warnings` and fix all errors
+3. Fix any small issues found. For big issues, confirm with the user first
+4. Amend changes into the most recent commit: `git add -A && git commit --amend --no-edit`
+5. Push: `git push --force-with-lease`
+6. Monitor CI on GitHub to ensure it passes. If it fails:
+   - Analyze why the issue was missed
+   - Update the pre-CI checks to catch similar issues
+   - Fix the problem and repeat from step 1
+
+Note: For a full local CI check matching what runs on GitHub, use `scripts/ci-local.py`
+
+Helpful commands for monitoring CI:
+- Check PR status: `gh pr checks <branch-name>`
+- Watch until completion: `gh pr checks <branch-name> --watch` (refreshes every 10s, exits when done)
+- View with details: `gh pr view <branch-name> --json statusCheckRollup --jq '.statusCheckRollup[] | "\(.name): \(.status) - \(.conclusion)"'`
