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.

Maintain Class Cohesion
Classes should have a small number of instance variables. Each method should manipulate one or more of those variables. The more variables a method manipulates, the more cohesive the method is to its class.
Incorrect (low cohesion - methods use different variables):
public class Utility {
private Database db;
private EmailService email;
private Logger logger;
private Cache cache;
public void saveUser(User user) {
db.save(user); // Only uses db
logger.log("Saved user"); // Only uses logger
}
public void sendNotification(String message) {
email.send(message); // Only uses email
}
public Object getCached(String key) {
return cache.get(key); // Only uses cache
}
}
// Each method uses different instance variables - low cohesion
Correct (high cohesion - methods use shared variables):
public class Stack {
private int topOfStack = 0;
private List<Integer> elements = new LinkedList<>();
public int size() {
return topOfStack; // Uses topOfStack
}
public void push(int element) {
topOfStack++; // Uses topOfStack
elements.add(element); // Uses elements
}
public int pop() throws EmptyStackException {
if (topOfStack == 0)
throw new EmptyStackException();
int element = elements.get(--topOfStack); // Uses both
elements.remove(topOfStack); // Uses both
return element;
}
}
// Every method uses the same instance variables - high cohesion
When cohesion breaks down: If a subset of methods only uses a subset of variables, extract those methods and variables into a separate class.
