Codex web-research-agent skill for source conflicts and dates

Check changing public information against primary sources, record dates and scope, and cite evidence in the answer.

Install in Codex

A Codex workspace with public-page access. This example supplies fictional excerpts only to illustrate research output format.

Review `.agents/skills/web-research-agent/SKILL.md` and its requirements at the pinned GitHub commit.
Create `.agents/skills/web-research-agent/` in your project and save the reviewed file as `.agents/skills/web-research-agent/SKILL.md`.
Start Codex from that project's root, then type `$web-research-agent` and select the matching skill.

question `Does the gallery allow large bags?`
fictional official visitor guide dated `2026-09-12`: `Large bags go to the coat check.`
fictional third-party listing dated `2024-02-03`: `Bags stay with visitors.`
scope weekday entry; no current holiday policy supplied
