.codex/skills/sp_dev/SKILL.md

sp_dev is a skill for Codex from ormastes/simple. It costs 28 tokens per session (19,440 once invoked), scanned A, original, no licence file.

A development workflow that turns a feature, bug, or TODO into clear acceptance criteria and then continues it through the SPipe process. Acceptance criteria are specific conditions used to decide whether work is complete.

In plain words
What is it for?
Refining features, bugs, and TODO items, defining acceptance criteria, and running the resulting work through SPipe.
Why use it?
It helps turn vague development requests into concrete, checkable outcomes before implementation proceeds.

Skill for Codex

Written for Codex: installed under .codex/.

This is ormastes/simple's own configuration. It tells Codex how to work on simple 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 simple configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is sh scripts/check/check-bootstrap-platform-handoff-readiness.shs.

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

sp_dev 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 today.

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.

The source is not reproduced here

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.
