What it does
Coding Style is an agent skill from modernweb-dev/rocket. Indexes this repo's coding conventions for file placement, tests, API shape, component authoring, and commit messages. Use when creating or editing source files, adding tests, designing function signatures, creating components, or writing commits in this repo.
Its SKILL.md is about 210 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `apis-and-functions.md`, `commits.md` and `components.md`).
It sits in Development, covering Commit messages and Static sites and blogs. The repository describes itself as: The modern web setup for static sites with a sprinkle of JavaScript. The licence is MIT.
When your agent uses it
- Editing source files
- Designing function signatures
- Creating components
- Writing commits in this repo
Example prompts
- “Use the coding-style skill to index this repo's coding conventions for file placement, tests, API shape, component authoring, and commit messages”
- “/coding-style”
What it can do on your machine
Read from SKILL.md and the folder at commit c4a9515. 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
Coding Style loads about 210 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 61 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.

- Indexes this repo's coding conventions for file placement, tests, API shape, component authoring, and commit messages. Use when creating or editing source files, adding tests, designing function signatures, creating components, or writing commits in this repo.
Coding Style
Open only the convention file needed for the current task. If a task spans multiple areas, read each relevant file before editing:
- Source and test files: see source-and-tests.md
- Function signatures and calls: see apis-and-functions.md
- Components: see components.md
- Commit messages: see commits.md
Prefer these conventions over generic language or framework defaults unless nearby code clearly establishes a narrower local pattern.
