📝 Walkthrough

Walkthrough

Documentation for the Apache SkyWalking output was updated: table header changed to "Key", an auth_token entry was added, defaults and ordering for host/port were normalized and reformatted, and example configuration keys were converted to CamelCase (svc_name → Svc_Name, svc_inst_name → Svc_Inst_Name).

Changes

Cohort / File(s)	Summary
Documentation pipeline/outputs/skywalking.md	Updated parameter table header to "Key", added auth_token, reformatted defaults (backticks) and reordered rows (host/port moved up), and changed example config keys to CamelCase (svc_name → Svc_Name, svc_inst_name → Svc_Inst_Name).

Poem

🐰 I hopped through docs with nimble paws,
I tucked in tokens, smoothed the rows,
CamelCase caps and tidy hosts,
A tiny tweak that softly shows,
Joyful hops for readers near and far!

- Around line 51-52: Replace the underscored classic config keys `Svc_name` and
`Svc_inst_name` with Title_Case `SvcName` and `SvcInstName` respectively; locate
all occurrences (e.g., the entries showing "Svc_name      dummy-service" and
"Svc_inst_name dummy-service-fluentbit") and update the key names, preserving
their values and spacing/formatting, and run any config validation or tests that
parse these keys to ensure nothing else relies on the old underscored names.
