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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01161 | $0.01161 |
| Opus 5 | $0.00580 | $0.00580 |
| Sonnet 5 | $0.00232 | $0.00232 |
| Haiku 4.5 | $0.00116 | $0.00116 |
Grade A, and why
apex-accelerator iac-terraform-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 11d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Terraform Best Practices
Region, tags, AVM-first mandate, unique suffix, and security baseline
are defined in AGENTS.md (always loaded). This file covers Terraform-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
including azurePropertyPath → Terraform argument translation tables.
Policy Compliance
Cross-reference 04-governance-constraints.json before writing templates.
Use azurePropertyPath (not bicepPropertyPath) for Terraform argument mapping.
See references/iac-policy-compliance.md for the full checklist, resource type
mapping table, and property path examples.
Provider and Backend
| Rule | Standard |
|---|---|
| Provider | Pin azurerm to ~> 4.0, random ~> 3.0 |
| Terraform | >= 1.9 |
| State backend | Azure Storage Account — never HCP Terraform Cloud |
Never use terraform { cloud {} } or reference TFE_TOKEN.

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.

apex-accelerator iac-terraform-best-practices.instructions.md is an instructions file published in the GitHub repository jonathan-vella/apex-accelerator (50 stars, last pushed 3d ago), licensed MIT. It adds 1,161 tokens to every session, about $0.0058 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).
