openusage: Skill for Codex

.codex/skills/iterate-feature/SKILL.md

iterate-feature is a skill for Codex from janekbaraniewski/openusage. It costs 14 tokens per session (64 once invoked), scanned A, original, MIT.

A procedure for revising a feature after problems are found or feedback is received.

In plain words
What is it for?
Use it when a feature needs fixes or changes based on review, testing, or other feedback.
Why use it?
It provides a named workflow for continuing work on an existing feature, but the input does not describe its individual steps.

Skill for Codex

Written for Codex: installed under .codex/.

This is janekbaraniewski/openusage's own configuration. It tells Codex how to work on openusage 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 openusage 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

iterate-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 6d 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.

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.
