name: "ring:dev-sre" description: | Gate 2 of the development cycle. VALIDATES that observability was correctly implemented by developers. Does NOT implement observability code - only validates it. license: MIT compatibility: platforms: - opencode

metadata: version: "1.0.0" author: "Lerian Studio" category: development trigger: - Gate 2 of development cycle - Gate 0 (Implementation) complete with observability code - Gate 1 (DevOps) setup complete - Service needs observability validation (logging, tracing) sequence: after: [ring:dev-devops] before: [ring:dev-testing]

SRE Validation (Gate 2)

Overview

This skill VALIDATES that observability was correctly implemented by developers:

• Structured logging with trace correlation
• OpenTelemetry tracing instrumentation
• Code instrumentation coverage (90%+ required)
• Context propagation for distributed tracing

Role Clarification

Developers IMPLEMENT observability. SRE VALIDATES it.

If observability is missing or incorrect:

1. SRE reports issues with severity levels
2. This skill dispatches fixes to the implementation agent
3. SRE re-validates after fixes
4. Max 3 iterations, then escalate to user

Required Input

• unit_id: Task/subtask being validated
• language: go / typescript / python
• service_type: api / worker / batch / cli / library
• implementation_agent: Agent that performed Gate 0
• implementation_files: Files created/modified in Gate 0

    VALIDATE Observability Implementation

    ## Context
    - Language: [language]
    - Service Type: [service_type]
    - Files to Validate: [implementation_files]

    ## Validation Checklist

    ### 0. FORBIDDEN Logging Patterns (Check FIRST)
    | Language | FORBIDDEN | Search For |
    |----------|-----------|------------|
    | Go | fmt.Println, log.Printf | grep in *.go |
    | TypeScript | console.log | grep in *.ts |

    If ANY FORBIDDEN pattern found: Severity CRITICAL, Verdict FAIL

    ### 1. Structured Logging
    - Uses lib-commons logger (Go) or lib-common-js (TypeScript)
    - JSON format with timestamp, level, message
    - trace_id correlation in logs

    ### 2. Instrumentation Coverage (90%+ required)
    Count spans in Handlers, Services, Repositories

    ### 3. Context Propagation
    For external calls: InjectHTTPContext, InjectGRPCContext

    ### Issues Found (if any)
    - Severity: CRITICAL/HIGH/MEDIUM/LOW
    - File: [path:line]
    - Fix Required By: [implementation_agent]

    ### Verdict
    **ALL CHECKS PASSED:** YES/NO
