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 Classes Small
Classes should be small. With functions, we measure size by counting lines. With classes, we count responsibilities. A class should have only one reason to change.
Incorrect (large class with multiple responsibilities):
public class SuperDashboard extends JFrame implements MetaDataUser {
public String getCustomizerLanguagePath() { /* ... */ }
public void setSystemConfigPath(String path) { /* ... */ }
public String getSystemConfigDocument() { /* ... */ }
public void setSystemConfigDocument(String doc) { /* ... */ }
public boolean getGuruState() { /* ... */ }
public boolean getNoviceState() { /* ... */ }
public boolean getOpenSourceState() { /* ... */ }
public void showObject(MetaObject object) { /* ... */ }
public void showProgress(String s) { /* ... */ }
public boolean isMetadataDirty() { /* ... */ }
public void setIsMetadataDirty(boolean dirty) { /* ... */ }
public Component getLastFocusedComponent() { /* ... */ }
// 70+ more methods...
}
Correct (small focused classes):
public class Version {
public int getMajorVersionNumber() { /* ... */ }
public int getMinorVersionNumber() { /* ... */ }
public int getBuildNumber() { /* ... */ }
}
public class Dashboard extends JFrame {
private final Version version;
private final UserPreferences preferences;
private final ProgressIndicator progress;
public void show() { /* ... */ }
}
public class UserPreferences {
public Language getLanguage() { /* ... */ }
public boolean isNovice() { /* ... */ }
public boolean isGuru() { /* ... */ }
}
public class ProgressIndicator {
public void showProgress(String message) { /* ... */ }
public void hideProgress() { /* ... */ }
}
Single Responsibility Principle (SRP): A class should have one, and only one, reason to change.
