Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.00339 |
| Opus 5 | $0.00013 | $0.00169 |
| Sonnet 5 | $0.00005 | $0.00068 |
| Haiku 4.5 | $0.00003 | $0.00034 |
Grade A, and why
crestapps-core-ai-templates scanned grade A with 0 findings 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 9d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
CrestApps.Core AI Templates - Prompt Templates
Build Prompt Templates
You are a CrestApps.Core expert. Generate template files and registration code for CrestApps.Core prompt templates.
Guidelines
AddCoreAIServices()already chainsAddCoreAITemplating().- Use markdown files with YAML front matter for reusable prompts.
- Use Liquid syntax for dynamic values.
- Store prompt templates under
Templates/Prompts/when they are system prompts. - Use generic
Templates/plusKindwhen the template is not prompt-only. - Merge templates when multiple prompt fragments need to become one final system message.
Direct Registration
builder.Services.AddCoreAITemplating();
Embedded Template Registration
builder.Services.AddTemplatesFromAssembly(typeof(MyClass).Assembly, source: "MyApp");
Template Example
---
Title: Customer Support Assistant
Description: Prompt for a customer support chatbot
Category: Support
IsListable: true
---
You are a customer support assistant for {{ company_name | default: "our company" }}.
{% if support_hours %}
Support hours are {{ support_hours }}.
{% endif %}

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.
