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.

## Minimize Function Arguments
|
|
|
|
The ideal number of arguments for a function is zero (niladic). Next comes one (monadic), followed closely by two (dyadic). Three arguments (triadic) should be avoided where possible.
|
|
|
|
**Incorrect (too many arguments):**
|
|
|
|
```java
|
|
// Flag arguments are bad - function does different things
|
|
public void render(boolean isSuite) {}
|
|
|
|
// Four arguments - hard to remember order
|
|
public Circle makeCircle(double x, double y, double radius, String color) {}
|
|
|
|
// Order matters and is easy to confuse
|
|
public void assertExpectedEqualsActual(String expected, String actual) {}
|
|
```
|
|
|
|
**Correct (minimized arguments):**
|
|
|
|
```java
|
|
// Separate functions instead of flag
|
|
public void renderForSingleTest() {}
|
|
public void renderForSuite() {}
|
|
|
|
// Encapsulate related arguments in objects
|
|
public Circle makeCircle(Point center, double radius, Color color) {}
|
|
|
|
// Even better - use a builder for many optional params
|
|
Circle circle = Circle.builder()
|
|
.center(new Point(0, 0))
|
|
.radius(5.0)
|
|
.color(Color.RED)
|
|
.build();
|
|
|
|
// Self-documenting method name
|
|
assertThat(actual).isEqualTo(expected);
|
|
```
|
|
|
|
**Why fewer arguments?**
|
|
- Easier to understand
|
|
- Easier to test (fewer combinations)
|
|
- Less chance of argument order errors
|
|
|
|
**Acceptable monadic forms:**
|
|
- Asking a question: `boolean fileExists(String path)`
|
|
- Transforming input: `InputStream openFile(String path)`
|
|
- Events: `void passwordAttemptFailed(int attempts)`
|
