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.

## Use Build-Operate-Check Pattern
|
|
|
|
Structure tests in three distinct phases: Build (arrange), Operate (act), Check (assert). This pattern makes tests easy to read and understand at a glance.
|
|
|
|
**Incorrect (mixed phases, unclear structure):**
|
|
|
|
```java
|
|
@Test
|
|
public void testOrder() {
|
|
Order order = new Order();
|
|
assertTrue(order.isEmpty());
|
|
Product product = new Product("Widget", 9.99);
|
|
order.add(product);
|
|
assertEquals(1, order.getItemCount());
|
|
assertEquals(9.99, order.getTotal(), 0.01);
|
|
order.add(product);
|
|
assertEquals(2, order.getItemCount());
|
|
assertEquals(19.98, order.getTotal(), 0.01);
|
|
}
|
|
```
|
|
|
|
**Correct (clear Build-Operate-Check):**
|
|
|
|
```java
|
|
@Test
|
|
public void addingProductShouldIncreaseItemCount() {
|
|
// Build
|
|
Order order = new Order();
|
|
Product widget = new Product("Widget", 9.99);
|
|
|
|
// Operate
|
|
order.add(widget);
|
|
|
|
// Check
|
|
assertEquals(1, order.getItemCount());
|
|
}
|
|
|
|
@Test
|
|
public void addingProductShouldUpdateTotal() {
|
|
// Build
|
|
Order order = new Order();
|
|
Product widget = new Product("Widget", 9.99);
|
|
|
|
// Operate
|
|
order.add(widget);
|
|
|
|
// Check
|
|
assertEquals(9.99, order.getTotal(), 0.01);
|
|
}
|
|
|
|
@Test
|
|
public void addingSameProductTwiceShouldDoubleTotal() {
|
|
// Build
|
|
Order order = new Order();
|
|
Product widget = new Product("Widget", 9.99);
|
|
|
|
// Operate
|
|
order.add(widget);
|
|
order.add(widget);
|
|
|
|
// Check
|
|
assertEquals(19.98, order.getTotal(), 0.01);
|
|
}
|
|
```
|
|
|
|
**Alias patterns:**
|
|
- Build-Operate-Check (BOC)
|
|
- Arrange-Act-Assert (AAA)
|
|
- Given-When-Then (BDD)
