What it does
Sveltekit is an agent skill from EpicenterHQ/epicenter. Apply SvelteKit patterns for routing, server modules, form actions, hooks, cookies, adapters, and invalidation. Use when editing route files, hooks, app.d.ts, or SvelteKit behavior.
Its SKILL.md is about 550 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. It works with SvelteKit and Svelte. The repository describes itself as: Open-source, local-first apps.
When your agent uses it
- Editing route files
- SvelteKit behavior
Example prompts
- “/sveltekit”
What it can do on your machine
Read from SKILL.md and the folder at commit 5b4bb69. 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
Links to these hosts (documentation or services it may open):
github.com
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
Sveltekit loads about 547 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 237 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 237 words (~547 tokens).
“When SvelteKit load behavior, invalidation, cookies, hooks, env handling, server-only modules, generated $types, or adapter behavior affects correctness, ask DeepWiki a narrow question against sveltejs/kit before relying on memory. Verify decisive details against local installed types and source.”
