Guides
Practical articles connected to the tools: debugging patterns, security notes, and real examples.
Choose a guide by problem
Start with the failure mode you are facing instead of opening random articles.
Start here when JSON fails to parse, looks malformed, or breaks API debugging.
Read this when tokens decode fine but access still fails or trust assumptions are shaky.
Useful when YAML looks valid but still behaves differently from what the platform expects.
Open this when dates look plausible but auth, sorting, UI, or jobs still behave incorrectly.
Browse by workflow
Use these groups when you know the area of the incident but not the exact guide yet.
When requests, responses, mocks, or schemas look plausible but still fail.
Practical guide: why JSON breaks, real examples, common mistakes, debugging tips, and FAQ.
Real-world comparison: when to choose YAML or JSON, examples, pitfalls (indentation/types), and a production checklist.
Practical guide: edge cases, realistic formats, consistency, sizes, and a QA/frontend checklist.
For token inspection, trust boundaries, issuer and audience mistakes, and auth incident triage.
Clear explanation: what decoding tells you, what you cannot know without signature verification, examples, pitfalls, and FAQ.
Practical checklist: tokens, headers, logs, screen sharing, extensions, and how to redact data in tickets.
A repeatable workflow to debug login/401 issues: clean token, inspect claims, convert exp, format errors, isolate root causes.
For YAML, scheduled jobs, platform differences, and production-oriented configuration mistakes.
Real-world comparison: when to choose YAML or JSON, examples, pitfalls (indentation/types), and a production checklist.
5-field cron guide: how to read it, production examples, common mistakes, and timezone checklist.
For UUIDs, timestamps, URL encoding, and values that change meaning across systems.
