What it does

Gtk Signal Result is an agent skill from hongquan/CoBang. Use when implementing work delegation in GTK4/Adwaita apps where Window → Parent Page → Child Page, and the child page's work result flows back up via signals to the layer that coordinates with other system components.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Python. The repository describes itself as: A QR code scanner desktop app for Linux. The licence is GPL-3.0.

Workflow steps

4 steps, taken from the step headings in SKILL.md.

Child Page: Declare Signal (class attribute style)
Child Page: Emit Signal with Result
Parent Page: Wire Signal to Handler in init
Parent Page: Handle Result

What it can do on your machine

Read from SKILL.md and the folder at commit 9278c46. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gtk Signal Result loads about 1.5k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 346 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~59
When it runs · the whole SKILL.md, loaded when a task matches: ~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Use when implementing work delegation in GTK4/Adwaita apps where Window → Parent Page → Child Page, and the child page's work result flows back up via signals to the layer that coordinates with other system components.

gtk-signal-result — Work Delegation with Result Callback via Signals

GTK4/Adwaita apps use GObject signals for child→parent result propagation instead of callback injection. The child page performs a subtask and emits the result; the parent (or Window) coordinates the result with other system components.

Delegation Chain

Window
  └── Parent Page (orchestrator, coordinates)
        └── Child Page A (performs subtask A, emits result via signal)
        └── Child Page B (performs subtask B, emits result via signal)

Key insight: The child knows nothing about what happens with its result. The parent coordinates multiple children and decides what to do with their combined outputs.

When to Use

Child page performs a focused subtask (collect input, generate data, scan)
Result needs to flow UP to coordinate with other components
Parent holds references to other children/pages that need the result
Anti-pattern to avoid: passing handler callbacks from parent to child

Pattern

1. Child Page: Declare Signal (class attribute style)

Prefer GObject.Signal as a class attribute (same style as WiFiSaver):

python

from gi.repository import GObject, Gtk

@Gtk.Template.from_resource('/path/to/template.ui')
class GeneratorStartingPage(Gtk.Box):
    __gtype_name__ = 'GeneratorStartingPage'

    generate_qr = GObject.Signal(
        'generate-qr',
        flags=GObject.SignalFlags.RUN_LAST,
        arg_types=(str,),
    )
    switch_to_wifi = GObject.Signal('switch-to-wifi', flags=GObject.SignalFlags.RUN_LAST)

If the natural attribute name would clash with a method, pick a distinct attribute (e.g. signal_request_camera_access) while keeping the signal string name stable.

2. Child Page: Emit Signal with Result

python

@Gtk.Template.Callback()
def on_btn_generate_clicked(self, _btn: Gtk.Button):
    text = self.text_entry.get_text().strip()
    if text:
        self.generate_qr.emit(text)  # Emit result upward

3. Parent Page: Wire Signal to Handler in `init`

python

class GeneratorPage(Adw.Bin):
    __gtype_name__ = 'GeneratorPage'

    starting_page: GeneratorStartingPage = Gtk.Template.Child()
    wifi_page: GeneratorWiFiPage = Gtk.Template.Child()
    qr_code_page: GeneratorQRCodePage = Gtk.Template.Child()

    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        # Wire each child's signal to appropriate handler
        self.starting_page.generate_qr.connect(self.on_qr_code_generation_requested)
        self.starting_page.switch_to_wifi.connect(self.on_switch_to_wifi)
        self.wifi_page.generate_qr_for_wifi.connect(self.on_generate_qr_for_wifi_network)
        self.wifi_page.back_to_start.connect(self.on_back_to_start)

4. Parent Page: Handle Result

python

def on_qr_code_generation_requested(self, _src: GeneratorStartingPage, text: str):
    """Parent coordinates: take text from starting page, generate QR, show in qr_code_page."""
    qr = qrcode.QRCode(border=2)
    qr.add_data(text)
    qr.make(fit=True)
    img = qr.make_image(fill_color='black', back_color='white')
    # ... convert to texture, display in qr_code_page
    self.qr_code_page.set_original_text(text)
    self.qr_code_page.qr_picture.set_paintable(texture)
    self.active_sub_page = GeneratorSubPage.QR_CODE_RESULT

Signal Examples in This Project

Child Page	Signal	Payload	What Parent Does with Result
`GeneratorStartingPage`	`generate-qr`	`str`	Generate QR image, display in `qr_code_page`
`GeneratorStartingPage`	`switch-to-wifi`	—	Switch to wifi child page
`GeneratorQRCodePage`	`back-to-start`	—	Clear QR page, return to starting page
`GeneratorWiFiPage`	`request-saved-wifi-networks`	—	Load networks, populate wifi list
`GeneratorWiFiPage`	`generate-qr-for-wifi`	`WifiNetworkInfo`	Generate QR for selected network
`GeneratorWiFiPage`	`back-to-start`	—	Return to starting page
`ScannerPage`	`poll-wifi-connection-status`	`WifiInfoMessage`	Check if already connected
`ScannerPage`	`request-connect-wifi`	`WifiInfoMessage`	Connect to scanned WiFi

Adding a New Delegation Signal

Child page: Declare signal

python

work_done = GObject.Signal(
    'work-done',
    flags=GObject.SignalFlags.RUN_LAST,
    arg_types=(MyResult,),
)

Child page: Emit when work completes

python

@Gtk.Template.Callback()
def on_work_trigger(self, _btn: Gtk.Button):
    result = self.perform_work()
    self.work_done.emit(result)

Parent page: Wire signal in __init__

python

self.child_page.work_done.connect(self.on_child_work_done)

Parent page: Handle result (may coordinate with OTHER children)

python

def on_child_work_done(self, _src: ChildPage, result: MyResult):
    # Parent coordinates: maybe update another child, trigger system action, etc.
    self.other_child.update(result)
    self.system_component.process(result)

Key Principles

Child is dumb about result fate — only emits signal, knows nothing of parent
Parent is the coordinator — wires signals, holds refs to all children
Signal carries typed result — use arg_types tuple for payload type
Handler gets source — first param is emitting child (use _src if not needed)
Result may need further processing — parent does coordination, not just UI updates
