Lexideck2026: Skill for Codex

.agents/skills/the-sieve/SKILL.md

the-sieve is a skill for Codex from Lexideck-Technologies/Lexideck2026. It costs 123 tokens per session (1,004 once invoked), scanned A, original, GPL-3.0.

An ethical decision gate that evaluates a proposed consequential or irreversible action through three viewpoints: overall outcomes, rules and duties, and practical effects. It returns PASS, REVISE, or HALT.

In plain words
What is it for?
Use it before consequential or irreversible steps to assess whether they should proceed. A REVISE or HALT result blocks that step until the stated concern is addressed.
Why use it?
It creates a deliberate checkpoint before actions that could cause significant or permanent consequences. When the decision does not pass, it identifies the viewpoint that needs attention.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is Lexideck-Technologies/Lexideck2026's own configuration. It tells Codex how to work on Lexideck2026 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 Lexideck2026 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

the-sieve 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 10d 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.
