npx skills add majiayu000/claude-skill-registry --skill nw-investigation-techniques --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Investigation Techniques ## Problem Categorization ### Technical Problems | Category | Sub-Category | Common Symptoms | |----------|-------------|-----------------| | System Failures | App crashes, memory leaks, deadlocks, data corruption | Service unavailability, resource exhaustion, integrity errors | | System Failures | Hardware, network, database, security | Connectivity loss, capacity limits, access failures | | Performance | Response time: slow queries, latency, algorithmic inefficiency | High p95/p99, user-reported slowness | | Performance | Throughput: thread pool exhaustion, connection limits, queue backlog | Reduced capacity, growing queues | | Integration | Internal: component comms, data format, version conflicts | Interface errors, serialization failures | | Integration | External: third-party availability, API changes, auth failures | Timeouts, contract violations | ### Operational Problems | Category | Common Symptoms | |----------|-----------------| | Deployment: script failures, config drift, migration errors | Failed releases, environment inconsistencies | | Monitoring: alerting gaps, backup failures, incident response | Missed incidents, slow recovery | | Human

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill nw-investigation-techniques --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 majiayu000/claude-skill-registry, a repository with 534 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.
