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.

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 | $0.00020 | $0.00514 |
| Opus 5 | $0.00010 | $0.00257 |
| Sonnet 5 | $0.00004 | $0.00103 |
| Haiku 4.5 | $0.00002 | $0.00051 |
Grade A, and why
system-integration 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
CIEL ADAPTATION: System Integration (Ports & Adapters)
This skill formalizes the "Hexagonal" approach to integrations. It ensures business logic remains independent of frameworks, transport, and external APIs.
The Hexagonal Core
- Domain Model: Pure entities and business rules. Zero framework imports.
- Ports (Interfaces):
- Inbound: What the app can do (e.g.,
CreateOrderPort). - Outbound: What the app needs (e.g.,
PaymentGatewayPort).
- Inbound: What the app can do (e.g.,
- Adapters (Impls): Concrete implementations (e.g.,
StripeAdapter,PostgresRepo).
Connector Builder Workflow (The House Style)
When adding a new integration, the Orchestrator MUST:
- Audit Patterns: Inspect 2+ existing connectors to map file layout and config schema.
- Match Boundaries: Do not invent a new architecture; use the host repo's existing abstraction layers.
- Registry Wiring: Ensure the new connector is correctly registered in the host's discovery/DI system.
Validation Standard
- Unit Test: Test UseCases with memory-fakes for ports.
- Contract Test: Verify that adapters fulfill the port's interface requirements.
- Evidence-First: Include live proof of successful auth/handshake in the final report.
Anti-Patterns
- Adapter Leakage: Leaking SDK-specific types (e.g.,
Stripe.Charge) into the domain layer. - Cargo-Culting: Copying an old, deprecated connector pattern just because it exists.
- Blind Transport: Writing transport code without error-handling or retry logic.
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.

system-integration is a skill published in the GitHub repository jxoesneon/Ciel (1 stars, last pushed 5d ago), licensed Apache-2.0. It adds 20 tokens to every session and 514 once invoked, about $0.0001 per session on Opus 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 2026-09-03.
