feature

feature is a command for coding agents from nbpadilha/nbp-skillforge. It costs 8 tokens per session (130 once invoked), scanned A, original, MIT.

A command for implementing a software feature across all required layers of a project.

In plain words
What is it for?
Use it for end-to-end feature development that requires changes in multiple parts of a codebase.
Why use it?
It organizes the work into verifiable steps so each part of a multi-layer change can be checked during implementation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 4d 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 it actually says

Feature

Implement the feature across all required layers.

Working folder

At the start, create this run's folder:

RUN_DIR=$(run-dir feature "$DESC" --track)

The logic (slug, timestamp, tracking) lives in the script — the skill does not restate it.

Break it into verifiable steps and validate each layer.

Changes

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.
