What it does

Cisco iOS Patterns is an agent skill from affaan-m/ECC. Cisco IOS and IOS-XE review patterns for show commands, config hierarchy, wildcard masks, ACL placement, interface hygiene, and safe change-window verification. Use when reading, writing, or reviewing Cisco IOS / IOS-XE configuration or planning a change window.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile. It works with iOS. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.

When your agent uses it

  • Reviewing Cisco IOS / IOS-XE configuration
  • Planning a change window

Example prompts

  • “/cisco-ios-patterns”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  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.

What it can do on your machine

Read from SKILL.md and the folder at commit 4eb71d9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cisco iOS Patterns loads about 1.3k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 499 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 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.

Read-Only Collection

text
show version
show inventory
show processes cpu sorted
show memory statistics
show logging
show running-config | section line vty
show running-config | section interface
show running-config | section router bgp
show ip interface brief
show interfaces
show interfaces status
show vlan brief
show mac address-table
show spanning-tree
show ip route
show ip protocols
show ip access-lists
show route-map
show ip prefix-list

Collect the specific section you need instead of dumping full config into a ticket when the config may contain secrets, customer names, or private topology.

Wildcard Masks

IOS ACL and many routing statements use wildcard masks, not subnet masks.

text
Subnet mask       Wildcard mask
255.255.255.255   0.0.0.0
255.255.255.252   0.0.0.3
255.255.255.0     0.0.0.255
255.255.0.0       0.0.255.255

Review wildcard masks before deployment. A subnet mask accidentally used as a wildcard can match far more traffic than intended.

text
ip access-list extended WEB-IN
  10 permit tcp 192.0.2.0 0.0.0.255 any eq 443
  999 deny ip any any log

Every ACL has an implicit deny at the end. Add an explicit logged deny when the operational goal includes observing misses, and confirm logging volume is safe.

ACL Placement Review

Before applying an ACL to an interface, answer these questions:

  • Which traffic direction is being filtered, in or out?
  • Is management traffic sourced from a known jump host or management subnet?
  • Is there an explicit permit for required routing, DNS, NTP, monitoring, or application traffic?
  • Are hit counters available from a safe test source?
  • Is there a rollback command and an active console or out-of-band path?

Do not test reachability by removing firewall or ACL protections. Read counters, logs, and route state first.

Interface Hygiene

text
interface GigabitEthernet0/1
 description UPLINK-TO-CORE
 switchport mode trunk
 switchport trunk allowed vlan 10,20,30
 switchport trunk native vlan 999
 no shutdown

Use clear descriptions, explicit switchport mode, and documented native VLANs. On routed interfaces, confirm the mask, peer addressing, and routing process before assuming link state means forwarding is correct.

Change-Window Verification

Use before/after checks that match the actual change.

text
show running-config | section interface GigabitEthernet0/1
show interfaces GigabitEthernet0/1
show logging | include GigabitEthernet0/1|changed state|line protocol
show ip route <prefix>
show ip access-lists <name>

For routing changes, also capture neighbor state and route tables before and after the change. For ACL changes, compare hit counters from a planned test source rather than relying on a generic ping.

Anti-Patterns

  • Applying a generated config without a device-specific diff.
  • Saving configuration before post-change checks pass.
  • Using a subnet mask where IOS expects a wildcard mask.
  • Applying an ACL to the wrong interface direction.
  • Troubleshooting by disabling ACLs, route policies, or authentication.
  • Pasting full configs into public tools without sanitizing secrets and topology.
