Audits code for observability gaps like leftover debug logs, unlogged errors, missing log context, and untracked slow operations using existing tooling.
From meridiannpx claudepluginhub markmdev/meridianThis skill uses the workspace's default tool permissions.
references/observability-patterns.mdGuides Next.js Cache Components and Partial Prerendering (PPR) with cacheComponents enabled. Implements 'use cache', cacheLife(), cacheTag(), revalidateTag(), static/dynamic optimization, and cache debugging.
Migrates code, prompts, and API calls from Claude Sonnet 4.0/4.5 or Opus 4.1 to Opus 4.5, updating model strings on Anthropic, AWS, GCP, Azure platforms.
Details PluginEval's skill quality evaluation: 3 layers (static, LLM judge), 10 dimensions, rubrics, formulas, anti-patterns, badges. Use to interpret scores, improve triggering, calibrate thresholds.
Code that works locally but is impossible to debug in production. This skill finds and fixes observability gaps using whatever tools the app already has.
Before anything else, explore the codebase to understand what's already in use:
logger or telemetry utilities?Read how they're configured and how they're used in existing code. All fixes must use these — never introduce a new observability dependency or pattern.
Debug artifacts left in production code:
console.log, console.debug, console.info that aren't part of the established logging patternErrors that disappear:
catch(e) that propagates or re-throws without logging first — the error reaches the user but leaves no trace for debugginglogger.error(e) alone, with no info about what operation failed, what inputs were involved, or what the user was doingMissing context on log entries:
Untracked slow or critical operations:
console.log goes away entirely — no conversion to structured log, just deletedreferences/observability-patterns.md — Detection patterns, bad/fix examples for debug artifacts, missing logging, missing context, untracked operations. Read before starting the audit.Summarize by file: what was removed, what was added or improved, what context was missing and is now included.
