Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.01192 |
| Opus 5.5 | $0.00023 | $0.00477 |
| Sonnet 5.5 | $0.00011 | $0.00238 |
| Haiku 4.5 | $0.00006 | $0.00119 |
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 1mo 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.
This is a copy
89% identical to cisco-ios-patterns — 27 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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
showcommands 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:
- Capture current state with read-only commands.
- Review the exact candidate config.
- Confirm management access cannot be locked out.
- Apply the smallest change in a maintenance window.
- Re-read state, compare to the baseline, then save only after validation.
Mode Reference
Router> enable
Router# show running-config
Router# configure terminal
Router(config)# interface GigabitEthernet0/1
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.

cisco-ios-patterns is a skill published in the GitHub repository unrealandychan/clean-code-skill (12 stars, last pushed 1mo ago), licensed MIT. It adds 57 tokens to every session and 1,192 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 89% identical to cisco-ios-patterns, differing in 27 lines, and is treated as a copy.
