cisco-ios-patterns

cisco-ios-patterns is a skill for Claude Code, Codex from gongyijie85/dsh-ecc. It costs 57 tokens per session (1,192 once invoked), scanned A, a copy of cisco-ios-patterns, MIT.

A review guide for Cisco IOS and IOS-XE, the operating systems used on many Cisco routers and switches. It covers command patterns, configuration levels, access-control lists, interfaces, and safe verification.

In plain words
What is it for?
Use it to review Cisco configurations, choose read-only troubleshooting commands, check ACL wildcard masks and interface direction, and prepare a maintenance-window checklist. It also helps verify that an intentional change is present and saved.
Why use it?
Router and switch changes can interrupt management access or affect traffic if applied in the wrong place. This encourages recording the current state, checking the proposed change, and validating the result before saving it.

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

cisco-ios-patterns 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.

Origin

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

Router(config-if)# description UPLINK-TO-CORE
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# end
Router# show running-config interface GigabitEthernet0/1

running-config is active memory. startup-config is what survives reload. Do not save a change just because a command was accepted; validate behavior first, then use copy running-config startup-config if the change is approved.

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.
