Documentation verification job
Security scanning job (safety + bandit)
Build summary generation

✅ Code Quality

Type hints across all public functions (100% coverage)
Specific exception handling (no bare except Exception)
Input validation (IP addresses, ports, IDs)
Migration logic for favorites file format
Zero lint errors (ruff, black, mypy)

✅ Dependencies & Config

Added pyproject.toml, requirements.txt, ruff.toml for youtubetv
Created .env.example files for all skills
Configured linting infrastructure with scripts/lint.sh

Modified Files

skills/youtubetv/scripts/wrapper.py - Logging integration, docstrings, refactoring
skills/youtubetv/scripts/dial.py - Type hints updates
skills/youtubetv/scripts/ytv_dial.py - Simplified refactoring
skills/chromecast/scripts/* - Type hints
skills/ffmpeg/scripts/* - Type hints
skills/serpapi/scripts/search.py - Type hints

Testing

All tests passing:

pytest skills/youtubetv/scripts/ -v
# 19 passed

All lint checks passing:

bash scripts/lint.sh
# All checks passed!

Breaking Changes

None - all changes are backward compatible.

skills/chromecast/scripts/.env.example

I don't think the .env.example file is necessary, since there are no .env files in the skills.

The skill environments are created dynamically for each user individually when a skill is configured or installed.

Also... this is serpapi config for chromecast skill?

skills/ffmpeg/scripts/.env.example

I don't think the .env.example file is necessary, since there are no .env files in the skills.

The skill environments are created dynamically for each user individually when a skill is configured or installed.

Also... this is serpapi config for ffmpeg?

skills/youtubetv/scripts/test_wrapper_extended.py

This test isn't actually testing the real skill; it's just mocking both the functionality and the result, so it's not viable.

sammwyy · 2026-02-20T06:38:27Z

skills/youtubetv/scripts/ytv_dial.py

-        """
-        Query the current YouTube app state on the device.
-
-        Returns
-        -------
-        AppState
-
-        Raises
-        ------
-        requests.HTTPError
-            Some Philips / MediaTek TVs return 403 until the app is launched.
-        """


I don't think removing documentation from functions is a good idea.

skills/youtubetv/CICD.md

I think this is over-engineering; you don't really need to document the skill, do you?

At some point, I think it would be better to remove the built-in skills and have each one in a separate repository. What do you think?

sammwyy · 2026-02-20T06:40:13Z

skills/youtubetv/LOGGING.md

I don't think it's necessary; only the LLM sees this logging anyway.

sammwyy · 2026-02-20T06:43:21Z

src/api/middleware/rateLimit.middleware.ts

+export const resetLoginAttempts = (ip: string, username: string) => {
+    const userKey = `${ip}:${username}`;
+    loginAttempts[userKey] = 0;
+};


It would be better to remove the entry to avoid memory leaks (in case of a DDoS attack with thousands of IPs).

delete loginAttempts[userKey]

or use a Map#remove(key: string)

SECURITY_AUDIT_REPORT.md

+**Severity**: HIGH  
+**Affected Files**: `src/api/routes/user/files.routes.ts:54-84`
+
+**Description**: File uploads are not validated, allowing upload of malicious files (webshells, scripts).
+
+**Remediation**: Implement file type whitelist and virus scanning.


The files here can only be accessed or executed by sandboxed shells, unless the user chooses to manually run malicious files outside the sandbox.

SECURITY_AUDIT_REPORT.md

+**Severity**: MEDIUM  
+**Affected Files**: `skills/youtubetv/scripts/dial.py:164`
+
+**Description**: XML parsing without disabling external entities.
+
+**Remediation**: Use secure XML parser configuration.


This runs in a sandbox

sammwyy · 2026-02-20T06:57:10Z

SECURITY_AUDIT_REPORT.md

+**Severity**: MEDIUM  
+**Affected Files**: Multiple error handlers
+
+**Description**: Error messages expose system paths, stack traces, and internal details.
+
+**Remediation**: Implement generic error messages in production.


The app runs by default in a docker container.
