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 | $0.00023 | $0.00270 |
| Opus 5.5 | $0.00009 | $0.00108 |
| Sonnet 5.5 | $0.00005 | $0.00054 |
| Haiku 4.5 | $0.00002 | $0.00027 |
Grade A, and why
Runtime Architecture 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 2mo 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
Work stack-neutrally. First identify the language, framework, hosting model, and existing runtime patterns. Then specify:
For small local tools or simple product slices, keep this as a compact checklist of decisions and risks. Do not expand into a full platform architecture unless the task involves services, workers, concurrency, permissions, deployment, or other real runtime complexity.
- Runtime objects, processes, workers, queues, jobs, or services and who owns each piece of state.
- Concurrency or async strategy: locks, event loops, promises, threads, workers, actors, transactions, cancellation, retries, backpressure, and resource limits as appropriate for the stack.
- Isolation boundaries for users, tenants, sessions, requests, permissions, cache entries, secrets, and temporary files.
- Event flow, ordering assumptions, failure modes, retry/idempotency behavior, and persistence points.
- Compatibility with existing APIs and behavior, including migration or rollout risks.
- Observability needed to debug failures without leaking sensitive data.
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.

Runtime Architecture is a skill published in the GitHub repository GongShichen/LuminaCode (9 stars, last pushed 4d ago), licensed Apache-2.0. It adds 23 tokens to every session and 270 once invoked, about $0.0001 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.
