network-bgp-diagnostics
Diagnostics-only BGP troubleshooting patterns for neighbor state, route exchange, prefix policy, AS path inspection, and safe evidence collection.
npx skills add mturac/everything-openai-codex --skill network-bgp-diagnostics --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.
# Network BGP Diagnostics Use this skill when a BGP session is down, flapping, established with missing routes, or advertising unexpected prefixes. The default workflow is read-only evidence collection; policy and reset actions belong in a reviewed change window. ## When to Use - BGP neighbors are stuck in Idle, Connect, Active, OpenSent, or OpenConfirm. - A session is Established but expected prefixes are missing. - A route-map, prefix-list, max-prefix limit, or AS path policy may be filtering routes. - You need before/after evidence for a BGP change. - You are reviewing automation that parses BGP summary output. ## Read-Only Triage Flow 1. Identify the exact neighbor, address family, VRF, and local/remote ASNs. 2. Capture summary state and last reset reason. 3. Prove reachability to the peer source address. 4. Check route policy references before assuming transport failure. 5. Compare advertised, received, and installed routes where the platform supports those commands. ```text show bgp summary show bgp neighbors <peer> show ip route <peer> show tcp brief | include <peer>|:179 show logging | include BGP|<peer> show running-config | section router bgp show ip prefix-list show rout

What does the network-bgp-diagnostics skill do?
Diagnostics-only BGP troubleshooting patterns for neighbor state, route exchange, prefix policy, AS path inspection, and safe evidence collection.
How do I install it?
Run `npx skills add mturac/everything-openai-codex --skill network-bgp-diagnostics --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.
