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.

Abstract Logging Behind Domain Interfaces
Logging frameworks are infrastructure details. Define logging interfaces in the application layer; implement them in infrastructure. This enables switching loggers and keeps domain pure.
Incorrect (logging framework in domain/application):
package usecases
import (
"github.com/sirupsen/logrus" // Framework dependency
)
type CreateOrderUseCase struct {
repo OrderRepository
logger *logrus.Logger // Concrete logger
}
func (uc *CreateOrderUseCase) Execute(cmd CreateOrderCommand) (*Order, error) {
uc.logger.WithFields(logrus.Fields{
"customer_id": cmd.CustomerID,
"item_count": len(cmd.Items),
}).Info("Creating order")
order, err := uc.repo.Create(cmd)
if err != nil {
uc.logger.WithError(err).Error("Failed to create order")
return nil, err
}
uc.logger.WithField("order_id", order.ID).Info("Order created")
return order, nil
}
// Switching from logrus to zap requires changing all use cases
Correct (logging behind interface):
// application/ports/logger.go
package ports
type Logger interface {
Info(msg string, fields ...Field)
Error(msg string, err error, fields ...Field)
Debug(msg string, fields ...Field)
}
type Field struct {
Key string
Value interface{}
}
func F(key string, value interface{}) Field {
return Field{Key: key, Value: value}
}
// application/usecases/create_order.go
package usecases
import "myapp/application/ports"
type CreateOrderUseCase struct {
repo OrderRepository
logger ports.Logger
}
func (uc *CreateOrderUseCase) Execute(cmd CreateOrderCommand) (*Order, error) {
uc.logger.Info("Creating order",
ports.F("customer_id", cmd.CustomerID),
ports.F("item_count", len(cmd.Items)),
)
order, err := uc.repo.Create(cmd)
if err != nil {
uc.logger.Error("Failed to create order", err,
ports.F("customer_id", cmd.CustomerID),
)
return nil, err
}
uc.logger.Info("Order created", ports.F("order_id", order.ID))
return order, nil
}
// infrastructure/logging/logrus_logger.go
package logging
import (
"github.com/sirupsen/logrus"
"myapp/application/ports"
)
type LogrusLogger struct {
logger *logrus.Logger
}
func (l *LogrusLogger) Info(msg string, fields ...ports.Field) {
l.logger.WithFields(toLogrusFields(fields)).Info(msg)
}
func toLogrusFields(fields []ports.Field) logrus.Fields {
result := logrus.Fields{}
for _, f := range fields {
result[f.Key] = f.Value
}
return result
}
// infrastructure/logging/zap_logger.go - Alternative implementation
// Switch without touching use cases
Benefits:
- Application code doesn't import logging frameworks
- Easy to switch logging backends
- Test logging by asserting on mock logger calls
