cisco-ios-patterns
Cisco IOS and IOS-XE review patterns for show commands, config hierarchy, wildcard masks, ACL placement, interface hygiene, and safe change-window verification.
npx skills add mturac/everything-openai-codex --skill cisco-ios-patterns --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Cisco IOS Patterns Use this skill when reviewing Cisco IOS or IOS-XE snippets, building a change-window checklist, or explaining how to collect evidence from a router or switch without making the incident worse. ## When to Use - Reviewing IOS or IOS-XE configuration before a planned change. - Choosing read-only `show` commands for troubleshooting. - Checking ACL wildcard masks and interface direction. - Explaining global, interface, routing process, and line configuration modes. - Verifying that a change landed in running config and was saved intentionally. ## Operating Rules Treat IOS examples as patterns, not paste-ready production changes. Confirm the platform, interface names, current config, rollback path, and out-of-band access before making changes on a real device. Prefer this workflow: 1. Capture current state with read-only commands. 2. Review the exact candidate config. 3. Confirm management access cannot be locked out. 4. Apply the smallest change in a maintenance window. 5. Re-read state, compare to the baseline, then save only after validation. ## Mode Reference ```text Router> enable Router# show running-config Router# configure terminal Router(config)# interface G

What does the cisco-ios-patterns skill do?
Cisco IOS and IOS-XE review patterns for show commands, config hierarchy, wildcard masks, ACL placement, interface hygiene, and safe change-window verification.
How do I install it?
Run `npx skills add mturac/everything-openai-codex --skill cisco-ios-patterns --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mturac/everything-openai-codex, a repository with 84 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
