SkilledAgent: Skill for Claude Code

.agents/skills/design-an-interface/SKILL.md

design-an-interface is a skill for Claude Code, Codex from AryanMotiani/SkilledAgent. It costs 43 tokens per session (711 once invoked), scanned A, original, no licence file.

A design workflow that uses parallel sub-agents to create several substantially different interface options for a software module. An interface is the set of operations and structure other code uses to interact with it.

In plain words
What is it for?
It is for designing APIs, exploring interface options, comparing module structures, or deliberately designing something more than once.
Why use it?
It helps compare alternative module shapes before choosing one implementation.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is AryanMotiani/SkilledAgent's own configuration. It tells Claude Code and Codex how to work on SkilledAgent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything SkilledAgent configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-an-interface scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
