+# Agent Instructions and Reminders
+
+This file contains important reminders and guidelines for AI agents working on this codebase.
+
+## Build Script
+
+### Avoid `-DisableCache` Flag
+
+**Do NOT use `-DisableCache`** when running `build.ps1` from agentic contexts. The `start.spring.io` service may block or rate-limit automated traffic, causing connection failures.
+
+Instead, to get a fresh build:
+
+1. Delete the expanded project folder (e.g., `workspace/springbootadmin/`)
+2. Run `.\build.ps1 <image-name>` without the flag
+
+### Testing Changes
+
+Before submitting patch changes:
+
+1. Run a dry-run of each patch: `git apply --check <patch-file>`
+2. If dry-run succeeds, run the full build and verify Java compilation
+3. Test the resulting Docker image with a real client app
+
+## Patch Files
+
+The build script uses `git apply --unidiff-zero --recount --ignore-whitespace` to apply patches, which is more forgiving than the traditional `patch` command.
+
+### Patch Format Rules
+
+1. **Hunk headers should be accurate**: The format is `@@ -old_start,old_count +new_start,new_count @@`
+   - `old_count` is the number of lines in the hunk from the old file (context lines plus lines with `-` prefix)
+   - `new_count` is the number of lines in the hunk in the new file (context lines plus lines with `+` prefix)
+   - For new file patches (`--- /dev/null`), `old_count` is 0 and `new_count` is the total number of lines in the new-file hunk
+   - Note: `--recount` will automatically correct line counts, but keeping them accurate is still good practice
+2. **Trailing newlines are required**: Patch files must end with a newline character.
+3. **Preserve exact whitespace**: Context lines must match the target file exactly, including trailing spaces and tabs. The `--ignore-whitespace` flag provides some tolerance but exact matches are preferred.
+4. **New file patches**: Use `/dev/null` as the old file:
+
+   ```diff
+   --- /dev/null

+   @@ -0,0 +1,N @@
+   +line 1
+   +line 2
+   ...
+   ```
+
+### Example
+
+If a patch adds 1 line, the hunk header should reflect this:
+
+```diff
+-@@ -37,3 +37,10 @@
++@@ -37,3 +37,11 @@
+```
+
+### Why This Matters
+
+While `git apply --recount` can fix minor line count issues, keeping patches accurate ensures reliable application and easier debugging.
