What it does
Favicon is an agent skill from brianlovin/agent-config. Generate a complete set of favicons from a source image and update HTML. Use when setting up favicons for a web project.
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering Static sites and blogs. The repository describes itself as: My coding agent config.
When your agent uses it

- Ensure Static Assets Directory Exists
- Generate Favicon Files
- Create/Update site.webmanifest

- Summary
What it can do on your machine
Read from SKILL.md and the folder at commit 1a9819e. 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
Shell commands in SKILL.md call:
magickbrewapt
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
Favicon loads about 2.2k tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 829 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteRuns commands with sudoSKILL.md:18
- **Linux**: `sudo apt install imagemagick`
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 829 words (~2,187 tokens).
“Generate a complete set of favicons from the source image at $1 and update the project's HTML with the appropriate link tags.”
