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.

Web Framework Concerns Stay in Interface Layer
HTTP-specific code (requests, responses, headers, cookies, sessions) belongs in the interface adapters layer. Use cases should be callable from any delivery mechanism.
Incorrect (use case coupled to HTTP):
// application/usecases/LoginUseCase.ts
import { Request, Response } from 'express'
import { sign } from 'jsonwebtoken'
export class LoginUseCase {
async execute(req: Request, res: Response) {
const { email, password } = req.body
const user = await this.users.findByEmail(email)
if (!user || !user.verifyPassword(password)) {
return res.status(401).json({ error: 'Invalid credentials' })
}
// Set HTTP-only cookie
const token = sign({ userId: user.id }, process.env.JWT_SECRET)
res.cookie('auth_token', token, {
httpOnly: true,
secure: process.env.NODE_ENV === 'production',
sameSite: 'strict'
})
return res.json({ user: { id: user.id, email: user.email } })
}
}
// Cannot call from CLI, message queue, or test without Express
Correct (use case independent of delivery):
// application/usecases/LoginUseCase.ts
export interface LoginCommand {
email: string
password: string
}
export interface LoginResult {
userId: string
email: string
authToken: string
}
export class LoginUseCase {
constructor(
private users: UserRepository,
private tokenService: TokenService
) {}
async execute(command: LoginCommand): Promise<LoginResult> {
const user = await this.users.findByEmail(command.email)
if (!user) {
throw new InvalidCredentialsError()
}
if (!user.verifyPassword(command.password)) {
throw new InvalidCredentialsError()
}
const token = this.tokenService.generate({ userId: user.id.value })
return {
userId: user.id.value,
email: user.email.value,
authToken: token
}
}
}
// interface/http/AuthController.ts
import { Request, Response } from 'express'
export class AuthController {
constructor(private loginUseCase: LoginUseCase) {}
async login(req: Request, res: Response) {
try {
const result = await this.loginUseCase.execute({
email: req.body.email,
password: req.body.password
})
// HTTP concerns in controller
res.cookie('auth_token', result.authToken, {
httpOnly: true,
secure: process.env.NODE_ENV === 'production',
sameSite: 'strict'
})
return res.json({
user: { id: result.userId, email: result.email }
})
} catch (error) {
if (error instanceof InvalidCredentialsError) {
return res.status(401).json({ error: 'Invalid credentials' })
}
throw error
}
}
}
// interface/cli/AuthCli.ts - Same use case, different delivery
export class AuthCli {
async login(email: string, password: string) {
const result = await this.loginUseCase.execute({ email, password })
console.log(`Logged in as ${result.email}`)
fs.writeFileSync('.auth_token', result.authToken)
}
}
Benefits:
- Same use case for HTTP, CLI, WebSocket, queue consumers
- Easy to test without HTTP mocking
- Web framework upgrades isolated to interface layer
