What it does
Remove Unused Includes is an agent skill from nwjs/chromium.src. Look through a given folder to find and safely remove unused includes specifically for Clang-compiled code (using clang-include-cleaner), verifying that referencing targets compile.
Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/remove_unused_includes.py`).
The repository describes itself as: Chromium codebase with NW.js modifications. Based on https://chromium.googlesource.com/chromium/src.git. The licence is BSD-3-Clause.
Example prompts
- “/remove-unused-includes”
Requirements
- Python 3
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit a9e8946. 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
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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
Remove Unused Includes loads about 392 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 140 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); the scripts in this folder are not scanned.

🧹 Remove Unused Includes Skill
This skill provides a workflow and script to look through a given folder,
identify unused includes using clang-include-cleaner, and safely remove them
only if the affected targets continue to compile successfully.
Prerequisites
- Compilation Database (
compile_commands.json): Ensure your compilation database is up-to-date. If not, generate a fresh compilation database using:bash python3 tools/clang/scripts/generate_compdb.py -p out/Default -o compile_commands.json
Workflow Steps
1. Run the Cleanup Script
Run the automated cleanup script located inside this skill's directory (resolve
the absolute <skill_directory_path> from the skill metadata):
python3 <skill_directory_path>/scripts/remove_unused_includes.py --src-root . --folder <relative_or_absolute_folder_path>2. Verify Compilation
The script automatically:
- Finds all
.ccfiles in the specified folder. - Detects unused includes using
clang-include-cleaner. - Locates all referencing GN targets for each modified file via
gn refs. - Edits the file and compiles each referencing target.
- Reverts the edit if any compilation errors occur.
3. Review Git Status
Once execution is complete, verify the final changes using git:
git status
