feature

feature is a skill for Claude Code from pierreb-devkit/Node. It costs 113 tokens per session (3,206 once invoked), scanned A, original, no licence file.

A structured workflow for implementing features, API endpoints, routes, or modules in a Node.js project. An API endpoint is a specific address that software uses to request or send data; the workflow covers planning, implementation, and testing across the project’s layers.

In plain words
What is it for?
Use it when building, adding, modifying, or implementing a feature, endpoint, API, route, or module.
Why use it?
It makes the agent examine scope and edge cases before changing code, then keeps related parts such as routes, controllers, services, and tests organised.

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

feature 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 12d 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
