observability SKILL.md skillA
observability from darknecrocities/skillbuilder is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add darknecrocities/skillbuilder/observability@git:20261025.6dc09bdPins git:20261025.6dc09bd in mdr.lock. Pin the fingerprint instead.

Observability and telemetry engineering skill. Enforces OpenTelemetry distributed tracing, structured JSON logging with correlation IDs, and health probes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Observability & Distributed Telemetry (`/observability`)
> **Philosophy**: *If it cannot be observed in production, it cannot be debugged. Correlate every log with a trace ID. Instrument every RPC boundary. Never emit unredacted PII.*
This skill establishes production observability standards across backend microservices, serverless functions, background workers, and containerized platforms.

How to install
mdr add darknecrocities/skillbuilder/observability@sha256:deb0e6708171483fThe line at the top of this page pins the label git:20261025.6dc09bd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
