apex-azure-reliabilityANALYSIS SKILL — Read-only reliability assessment for App Service and Azure Functions: zone redundancy, ZRS storage, health probes and multi-region failover.
Apex Azure Reliability is an agent skill from jonathan-vella/apex. ANALYSIS SKILL — Read-only reliability assessment for App Service and Azure Functions: zone redundancy, ZRS storage, health probes and multi-region failover. WHEN: "assess reliability", "zone redundant", "multi-region failover", "single points of failure", "disaster recovery readiness". DO NOT USE FOR: fixes or deploys (06b/06t), troubleshooting (apex-azure-diagnostics).
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `references/health-probe-checks.md`, `references/multi-region-checks.md` and `references/services/app-service/reliability.md`).
It sits in DevOps & Cloud, covering Backup and disaster recovery. It works with Microsoft Azure, Azure Functions and Model Context Protocol. The repository describes itself as: APEX turns Azure platform engineering requirements into verified, deploy-ready IaC — powered by GitHub Copilot agents, real-time pricing, and built-in compliance. The licence is MIT.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit b8e5908. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
azkindFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use az, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Apex Azure Reliability loads about 2.4k tokens when it runs, and up to ~9.8k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 634 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/apex-azure-reliability/SKILL.md (or your agent's skills folder). This skill also uses 6 other files; get the full folder from GitHub.Adapted from upstream azure-reliability. This skill assesses the reliability
posture of deployed App Service and Azure Functions resources and returns
findings. It never changes resources, patches IaC or deploys: fixes flow through
05-IaC Planner and 06b/06t.
| Property | Details |
|---|---|
| Best for | Reliability findings for 08-As-Built and 09-Diagnose |

| Tool | Purpose |
|---|---|
mcp_azure-mcp_extension_cli_generate | Generate read-only az commands for resource queries |
mcp_azure-mcp_subscription_list | List available subscriptions |
mcp_azure-mcp_group_list | List resource groups |

(--subscriptions <sub-id>) or app (| where name =~ '<app-name>').⚪ not assessed — never
invent commands or settings for them.cost-estimate-subagent.Platform discovery first:
| Platform check | Reference |
|---|---|
| Zone redundancy — discovery | zone-redundancy-checks.md |
| Storage redundancy (cross-service) | storage-redundancy-checks.md |
| Multi-region and global load balancers | multi-region-checks.md |
| Front Door / Traffic Manager / App Insights probes | health-probe-checks.md |
Then a per-service deep dive:
| Service detected | Reference |
|---|---|
Azure Functions (microsoft.web/serverfarms with kind contains 'functionapp') | services/functions/reliability.md |
App Service (microsoft.web/sites and microsoft.web/serverfarms without functionapp) | services/app-service/reliability.md |

Present a feature-pivoted table with four rows in this order: Zone redundancy — compute, Zone-redundant storage, Health probes, Multi-region failover. Each row has one status and the relevant resources:
🟢 ON — enabled on every relevant resource; 🟡 PARTIAL — some resources or partial configuration;
🔴 OFF — missing everywhere. For storage, show the SKU instead of OFF (🔴 LRS, 🔴 GRS, 🟢 ZRS, 🟢 GZRS).(FC1), (defaulted; no SKU set)).
Credit resources that are already compliant with — already ON.n/a cells.Reliability Assessment — {scope}
Reliability Feature Status Resources
Zone redundancy — compute 🔴 OFF • plan-web-{suffix} (P1v3)
Zone-redundant storage 🔴 GRS • st{suffix} (defaulted; no SKU set in IaC)
Health probes 🟡 PARTIAL • app-web-{suffix} — already ON
• func-api-{suffix} — needs code change (FC1)
Multi-region failover 🔴 OFF • Single region (swedencentral) — Front Door not configured| Priority | Criteria | Owner action |
|---|---|---|
| Critical | No zone redundancy AND production workload | Raise with the IaC owner now |
| High | LRS storage on zone-redundant compute | Plan the change within days |
| Medium | Single region but zone-redundant | Plan for the next change window |
| Low | Missing health probes or monitoring gaps | Track and fix |
Return findings to the calling agent; never write a standalone reliability artifact.
| Caller | Artifact | Sections that receive findings |
|---|---|---|
| 08-As-Built | 07-backup-dr-plan.md | Executive Summary availability row; 1. Recovery Objectives; 2. Backup Strategy; 3. Disaster Recovery Procedures; 4. Testing Schedule |
| 08-As-Built | 07-design-document.md | 8. Backup & Disaster Recovery |
| 09-Diagnose | 08-resource-health-report.md | Issues Identified (by severity); Prevention Recommendations; Next Steps |
Each finding states the resource, the current state, the target setting and its priority. Multi-region designs go to 05-IaC Planner as a recommendation; don't start multi-region work without explicit user consent.
| Error | Remediation |
|---|---|
| Authentication required | Ask the user to run az login locally, then retry |
| Access denied | Confirm a Reader role assignment on the scope |
| Plan doesn't support ZR | Record the plan upgrade path; price it through cost-estimate-subagent |
| Region doesn't support AZ | Record the limitation; suggest a zone-capable region |

Apex Azure Reliability is an agent skill from jonathan-vella/apex. ANALYSIS SKILL — Read-only reliability assessment for App Service and Azure Functions: zone redundancy, ZRS storage, health probes and multi-region failover.
Apex Azure Reliability fits situations like: deploys (06b/06t); troubleshooting (apex-azure-diagnostics).
Run `npx skills add jonathan-vella/apex --skill apex-azure-reliability -a claude-code`. Or copy the skill folder (.github/skills/apex-azure-reliability in jonathan-vella/apex) into .claude/skills/apex-azure-reliability in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jonathan-vella/apex --skill apex-azure-reliability -a codex`. Or copy the skill folder (.github/skills/apex-azure-reliability in jonathan-vella/apex) into .agents/skills/apex-azure-reliability in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jonathan-vella/apex --skill apex-azure-reliability -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/apex-azure-reliability, .gemini/skills/apex-azure-reliability, .github/skills/apex-azure-reliability and .opencode/skills/apex-azure-reliability in your project.
Going by SKILL.md and its folder, Apex Azure Reliability needs the command-line tools its instructions call (az and kind).
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Apex Azure Reliability is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.4k tokens (SKILL.md is roughly 9.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 7.4k tokens, read only when the agent opens those files.
