Three independently ugly bugs that all fed the same log flood:
* Electron's `WebFrameMain.send` writes every "Render frame was disposed"
to stderr via `console.error`. When the worker fans a second
agent-event past a reloading renderer, we produced thousands of
identical lines and stalled the main loop on stderr I/O. Added a
`mainFrame.detached` guard so the send is short-circuited before
Electron's own catch block fires, and installed a targeted filter in
`suppress-warnings.ts` (now actually imported from the entry point)
so the specific `console.error("Error sending from webFrameMain:"…)`
noise never reaches the terminal. Any other payload still surfaces.
* `dispatchAgentMessage` accepted the human-reader sentinel as a wake
target when an agent replied to `__board__` — `wakeAgentIfPossible`
then called `db.getAgent("__board__")`, threw, and the dispatcher
kept repeating on every send. Strip `HUMAN_SENDER_ID` at
`resolveMessageWakeTargets`, and keep a defense-in-depth guard in the
heartbeat so a stray caller (future automation fan-out) cannot
reintroduce the crash.
* Pi's skills loader rejects any SKILL.md whose frontmatter `name`
diverges from its parent directory. The four bundled `my-writing-style`
copies declared `name: writing-style-skill`, so every install emitted
a warning and dropped the skill. They also lived as orphan gitlinks
(mode 160000 without .gitmodules), and the global `*.md` gitignore
hid every other SKILL.md from version control. Fixed the frontmatter
to match the dir, converted the dangling submodules to plain trees,
and allowlisted `builtin-skills/**/*.md` so a fresh clone carries the
catalogue instead of silently losing it.

## Keep Tests Clean
|
|
|
|
Test code is just as important as production code. It requires thought, design, and care. If you let tests rot, they become a liability instead of an asset.
|
|
|
|
**Incorrect (dirty tests):**
|
|
|
|
```java
|
|
@Test
|
|
public void test1() {
|
|
// Cryptic, no clear purpose
|
|
S s = new S();
|
|
s.a("x");
|
|
s.b("y");
|
|
assertTrue(s.c());
|
|
s.d();
|
|
assertEquals("xy", s.e());
|
|
}
|
|
|
|
@Test
|
|
public void testEverything() {
|
|
// Multiple assertions testing different concepts
|
|
assertNotNull(user);
|
|
assertEquals("Bob", user.getName());
|
|
assertTrue(user.isActive());
|
|
assertEquals(3, user.getOrders().size());
|
|
assertTrue(user.getOrders().get(0).isPaid());
|
|
}
|
|
```
|
|
|
|
**Correct (clean, readable tests):**
|
|
|
|
```java
|
|
@Test
|
|
public void concatenatingTwoStringsShouldReturnCombinedResult() {
|
|
StringBuffer buffer = new StringBuffer();
|
|
|
|
buffer.append("first");
|
|
buffer.append("second");
|
|
|
|
assertEquals("firstsecond", buffer.toString());
|
|
}
|
|
|
|
@Test
|
|
public void userShouldBeActiveAfterActivation() {
|
|
User user = new User("Bob");
|
|
|
|
user.activate();
|
|
|
|
assertTrue(user.isActive());
|
|
}
|
|
|
|
@Test
|
|
public void activatingUserShouldSendWelcomeEmail() {
|
|
User user = new User("Bob");
|
|
EmailService emailService = mock(EmailService.class);
|
|
|
|
user.activate(emailService);
|
|
|
|
verify(emailService).sendWelcome(user.getEmail());
|
|
}
|
|
```
|
|
|
|
**Qualities of clean tests:**
|
|
- Readable: Clear setup, action, assertion
|
|
- One concept per test
|
|
- Descriptive names explaining what is being tested
