Design, audit, or implement application structured logging architecture from repository evidence. Use when a user asks whether or where to add logs, how to choose or migrate a logger, how to standardize events/fields/levels/redaction, how to add HTTP access or panic logs, or why production logs cannot answer an incident question. Do not use merely to tail platform logs or to design a full metrics, tracing, SLO, and incident-management program.
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
# Structured Logging Lite Build the smallest logging contract that makes the target system diagnosable without leaking data, duplicating audit records, or forcing an unnecessary logging-library migration. ## Operating Contract - **Direct actions:** Inspect repositories, manifests, runtime entrypoints, tests, deployment files, and existing logs. Make local logging changes only when the user asks to implement or upgrade them; treat design, review, and diagnosis requests as read-only. - **Escalate before:** Ask before publishing, pushing, changing remote observability infrastructure, touching production, or expanding from application logging into a full observability rollout. - **Evidence-backed pushback:** Challenge a requested library migration or log-everything plan only with repository evidence, a measured requirement, a concrete security/cardinality risk, or a smaller compatible alternative. - **Feedback loop:** Promote repeated missing fields, false-success signals, secret leaks, or manual incident queries into the field contract, gotchas, validation tests, or a deterministic helper. …

How to install
mdr add majiayu000/spellbook/structured-logging-lite@sha256:01073e38dfdb5706The line at the top of this page pins the label git:20260716.c6fdb3e, 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.
