What it does
Clean Room Porting is an agent skill from yquake2/yquake2remaster. Clean-room software development process for copying/porting functionality from mods with GPL-incompatible licenses. Use when porting features or code from proprietary, non-commercial, or restrictive mods into GPL-licensed projects (such as Quake II remasters) while maintaining strict legal separation via functional specifications and isolated black-box implementation.
Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Yamagi Quake II with Q2 Remaster support.
When your agent uses it
- Porting features
- Code from proprietary
Example prompts
- “/clean-room-porting”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Scope & License Verification
- Functional Specification Generation (Black-Box Analysis)
- Clean-Room Implementation
- Compliance & Verification Audit
What it can do on your machine
Read from SKILL.md and the folder at commit b401f5e. 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.
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
Clean Room Porting loads about 967 tokens when it runs. Until then it costs about 97 tokens; SKILL.md has 444 words of instructions outside code blocks.
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 444 words (~967 tokens).
“This skill provides a rigorous, legally sound workflow for porting functionality, mechanics, or features from mods carrying GPL-incompatible licenses (e.g., proprietary, source-available, non-commercial, restrictive custom licenses) into a GPL-licensed codebase (such as yquake2remaster).”
