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 | $0.00007 | $0.00363 |
| Opus 5.5 | $0.00003 | $0.00145 |
| Sonnet 5.5 | $0.00001 | $0.00073 |
| Haiku 4.5 | $0.00001 | $0.00036 |
Grade A, and why
test-design 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
Skill: test-design
Test Design
Purpose
Create tests that document expected behavior, catch regressions, and remain stable as implementation details change.
When to use it
- Whenever you add or change behavior.
- When a bug is found (write a failing test first, then fix).
Instructions
- Derive cases from requirements and edge cases, not from the implementation.
- Cover happy paths, error paths, boundaries, and empty/large inputs.
- Assert observable behavior and meaningful content.
- Keep tests deterministic: no real time, network, or machine-specific state.
- Name each test after the behavior it verifies.
Output format
Test files with clear names and assertions, plus a short mapping from tests to requirements.
Anti-patterns
- Asserting only existence ("file was created") without checking content.
- Coupling tests to internal details that should be free to change.
- Weakening a test to make a broken implementation pass.
Verification checklist
- Include positive, negative, boundary, malformed, empty, and large-input cases that are relevant to the requirement.
- Prove the regression test detects the old defect when practical.
- Keep fixtures minimal and isolate time, randomness, network, and filesystem state behind deterministic controls.
Apply
context-discoverybefore broad scanning: use a supplied context capsule first; otherwise check context frontmatter freshness, read.agent/context/routing.md, load only relevant summaries, and verify critical claims against source.
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.

test-design is a cursor rule published in the GitHub repository Oriolshhh/runware-image-mcp (0 stars, last pushed 3mo ago), licensed MIT. It adds 7 tokens to every session and 363 once invoked, about $0.0000 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 2026-09-03.
