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 | $0.00165 |
| Opus 5.5 | $0.00008 | $0.00066 |
| Sonnet 5.5 | $0.00004 | $0.00033 |
| Haiku 4.5 | $0.00002 | $0.00016 |
Grade A, and why
switchyard-runtime-check 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 1mo 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
Switchyard Runtime Check
Use this skill when you want to verify the Campus consumer seam while keeping runtime transport behind the optional local Switchyard boundary.
Steps
- Call
GET /api/providers/status. - Confirm whether
switchyard.readyistrue. - If ready, use the Campus consumer seam or
/api/providers/switchyard/chat. - Preserve Campus response semantics:
answerText, optionalstructuredAnswer,nextActions,trustGaps, andcitations.
Hard boundary
- Do not bypass Campus semantics by exposing raw upstream provider payloads.
- Do not describe this as hosted autonomy or a write-capable agent runtime.
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.

switchyard-runtime-check is a skill published in the GitHub repository xiaojiou176-open/campus-copilot (2 stars, last pushed 1mo ago), licensed MIT. It adds 20 tokens to every session and 165 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings.
