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 | $0.00016 | $0.00217 |
| Opus 5 | $0.00008 | $0.00109 |
| Sonnet 5 | $0.00003 | $0.00043 |
| Haiku 4.5 | $0.00002 | $0.00022 |
Grade A, and why
contract-tests 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
Context
Use when changing packages/client/src/lib/api.ts, Express routes, shared types/constants, repository return shapes, or WebSocket payloads.
Patterns
- For REST changes, prove the client path/method/body matches the server route.
- For shared types, update all consumers in client/server/runtime together.
- For WebSocket events, check the persisted event shape, broadcast shape, and rendered shape.
- Prefer local-runnable focused tests over tests that require production services.
Examples
- A task route path change should include both route-level server coverage and client API expectation coverage.
- An AgentEvent shape change should include server event mapping and AgentPanel rendering evidence.
Anti-Patterns
- Do not rely on mocked client tests that never exercise the real route path.
- Do not duplicate types locally in the client or server.
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.

contract-tests is a skill published in the GitHub repository DanWahlin/ai-agent-board (57 stars, last pushed 14d ago), licensed MIT. It adds 16 tokens to every session and 217 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 2026-08-30.
