Observability Tracing
Overview
Use this skill to make critical request flows traceable end-to-end for latency and failure diagnosis.
Scope Boundaries
- Use this skill when the task matches the trigger condition described in
description. - Do not use this skill when the primary task falls outside this skill's domain.
Shared References
- Span attribute and sampling rules:
references/span-attribute-and-sampling-rules.md
Templates And Assets
- Trace coverage map template:
assets/trace-coverage-map-template.md
- Trace quality checklist:
assets/trace-quality-checklist.md
Inputs To Gather
- Critical cross-service user flows.
- Current instrumentation and propagation gaps.
- Sampling constraints and storage budget.
- Incident diagnosis requirements.
Deliverables
- Trace coverage map for critical paths.
- Span attribute conventions and sampling policy.
- Validation evidence for trace queryability.
Workflow
- Define coverage targets in
assets/trace-coverage-map-template.md. - Apply span/sampling policy from
references/span-attribute-and-sampling-rules.md. - Validate quality via
assets/trace-quality-checklist.md. - Fix missing spans/attributes on critical paths.
- Publish tracing baseline and ownership.
Quality Standard
- Critical flows are traceable end-to-end.
- Span attributes are consistent for diagnosis queries.
- Sampling preserves incident usability.
Failure Conditions
- Stop when critical paths remain untraceable.
- Stop when trace context propagation is inconsistent.
- Escalate when tracing gaps block root-cause isolation.

graph-algorithms
Graph algorithm workflow for modeling entities/relations and selecting traversal, path, ordering, or flow strategies. Use when correctness or performance depends on graph representation and algorithm choice; do not use for schema-only modeling or deployment topology planning.
14bash-style-guide
Style, review, and refactoring standards for Bash shell scripting. Trigger when `.sh` files, files with `#!/usr/bin/env bash` or `#!/bin/bash`, or CI workflow blocks with `shell: bash` are created, modified, or reviewed and Bash-specific quality controls (quoting safety, error handling, portability, readability) must be enforced. Do not use for generic POSIX `sh`, PowerShell, or language-specific application style rules. In multi-language pull requests, run together with other applicable `*-style-guide` skills.
11architecture-clean-architecture
Clean Architecture workflow for enforcing dependency direction, stable domain boundaries, and use-case-centered application design. Use when teams must separate business rules from frameworks and delivery mechanisms; do not use for isolated module cleanup without boundary implications.
11powershell-style-guide
Style, review, and refactoring standards for PowerShell scripting. Trigger when `.ps1`, `.psm1`, `.psd1` files, or CI workflow blocks with `shell: pwsh` or `shell: powershell` are created, modified, or reviewed and PowerShell-specific quality controls (error handling, parameter validation, readability, operational safety) must be enforced. Do not use for Bash, generic POSIX `sh`, or language-specific application style rules. In multi-language pull requests, run together with other applicable `*-style-guide` skills.
10github-codeowners-management
Govern CODEOWNERS rules so review routing reflects real ownership and risk boundaries on GitHub. Use when repository ownership mapping or mandatory reviewer rules must be defined, updated, or audited; do not use for non-GitHub runtime architecture or data-layer design.
9security-authentication
Security workflow for authentication architecture, credential lifecycle, and session/token assurance. Use when login, identity proofing, MFA, or session security decisions are required; do not use for authorization policy design or non-security quality tuning.
