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 | $0.00175 | $0.02792 |
| Opus 5.5 | $0.00070 | $0.01117 |
| Sonnet 5.5 | $0.00035 | $0.00558 |
| Haiku 4.5 | $0.00017 | $0.00279 |
Grade A, and why
crestapps-core-ai-runtime 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CrestApps.Core AI Runtime
The runtime is the provider-agnostic layer every other AI feature builds on. A connection holds credentials and an endpoint, a deployment names a model on a connection and declares what that model can do, and a slot says what the installation uses a deployment for.
Guidelines
- Prefer
AddCrestAppsCore(...).AddAISuite(...)for application composition. UseAddCoreAIServices()only when the host composes raw service registrations itself. - Program against
IAIClientFactory,IAICompletionService,IAICompletionContextBuilderandIAIDeploymentManager. Never create a provider SDK client in business code. - Every configured deployment declares its model capabilities through
Features. A configured entry with no features and no legacy purpose is skipped at startup with the warning "declares no model capabilities". - Pick deployments through slots (
AIDeploymentSlotNames) andResolveSlotAsync(...). There is no deployment purpose or type in 2.0. - Use
crestapps-core-ai-model-capabilitiesfor registering features, parameters and slots,crestapps-core-ai-usage-meteringfor usage records, and the provider skills (crestapps-core-openai,crestapps-core-azure-openai,crestapps-core-ollama,crestapps-core-azure-ai-inference) for provider-specific settings.
Registration
using CrestApps.Core.AI;
using CrestApps.Core.AI.OpenAI;
builder.Services.AddCrestAppsCore(crestApps => crestApps
.AddAISuite(ai => ai
.AddOpenAI()
)
);
AddAISuite(...) calls AddCoreServices(), AddCoreAIServices() and AddCoreAIOrchestration(). Without the builder:
builder.Services
.AddCoreAIServices()
.AddCoreAIOrchestration()
.AddCoreAIOpenAI();
AddCoreAIServices() also chains AddCoreAITemplating() and AddCoreAIDeploymentCapabilities() (features, parameters and slots). IAIDeploymentManager is registered by AddCoreAIOrchestration(), so register orchestration whenever code resolves deployments.
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.

crestapps-core-ai-runtime is a skill published in the GitHub repository CrestApps/CrestApps.AgentSkills (13 stars, last pushed yesterday), licensed MIT. It adds 175 tokens to every session and 2,792 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
