apex-accelerator: Instructions file for GitHub Copilot

.github/instructions/iac-bicep-best-practices.instructions.md

apex-accelerator iac-bicep-best-practices.instructions.md is an instructions file for GitHub Copilot from jonathan-vella/apex-accelerator. It costs 957 tokens per session, scanned A, original, MIT.

A set of Bicep rules for defining Azure infrastructure as code, meaning cloud resources described in files instead of created manually.

In plain words
What is it for?
It guides the creation and review of Azure Bicep templates, including resource names, parameters, modules, unique suffixes, and policy-related property mappings.
Why use it?
It helps Bicep templates comply with Azure security policies, naming limits, approved modules, and required resource conventions.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file. Also seen: mentions AGENTS.md.

This is jonathan-vella/apex-accelerator's own configuration. It tells GitHub Copilot how to work on apex-accelerator itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything apex-accelerator configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

apex-accelerator iac-bicep-best-practices.instructions.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bicep Best Practices

Region, tags, AVM-first mandate, unique suffix, and security baseline are defined in AGENTS.md (always loaded). This file covers Bicep-specific patterns. Policy constraints (04-governance-constraints.md) always take precedence.

Security

Azure Policy always wins. Code adapts to policy, never the reverse. See references/iac-security-baseline.md for shared security rules and references/iac-policy-compliance.md for the full policy compliance workflow.

Policy Compliance

Cross-reference 04-governance-constraints.json before writing templates. For Deny policies, prefer azurePropertyPath; fall back to bicepPropertyPath. See references/iac-policy-compliance.md for the full checklist and Bicep translation rules.

Naming

Resource Max Pattern Example
Storage 24 st{project}{env}{suffix} stcontosodev7xk2
Key Vault 24 kv-{project}-{env}-{suffix} kv-contoso-dev-abc123
SQL Server 63 sql-{project}-{env}-{suffix} sql-contoso-dev-abc123

Use lowerCamelCase for parameters, variables, resources, modules.

Unique Names

Generate uniqueSuffix once in main.bicep via uniqueString(resourceGroup().id). Pass to all modules. Use take() for length-constrained resources.

AVM Modules

Use AVM modules (br/public:avm/res/{service}/{resource}:{version}) for all resources where one exists. Raw Bicep only when no AVM exists and user approves.

Pin to the latest published stable version, resolved at plan time:

curl -sf https://mcr.microsoft.com/v2/bicep/avm/res/{path}/tags/list \
  | jq -r '.tags[]' | grep -E '^[0-9]+\.[0-9]+\.[0-9]+$' | sort -V | tail -1

Or use the mcp_bicep_list_avm_metadata MCP helper. Never copy a version from azure-defaults/references/avm-modules.md — versions are intentionally stripped from that table. The shared stale-pin exception and freeze policy lives in azure-defaults.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
