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.

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 | $0.00128 | $0.04426 |
| Opus 5.5 | $0.00051 | $0.01770 |
| Sonnet 5.5 | $0.00026 | $0.00885 |
| Haiku 4.5 | $0.00013 | $0.00443 |
Grade A, and why
stelow-workflow-testing-execution 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 14d 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.
How it starts
The opening of the file, as written. The whole thing — 426 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Testing Protocol
After implementing any feature, run this protocol before marking complete.
Why This Protocol
This protocol exists because of real patterns observed across projects:
- Unit tests pass ≠ user experience works. E2E testing captures real flow problems that no unit test detects: loading states, double-submit, empty states, network errors, responsiveness. E2E is the only guarantee that the user experience works.
- Accessibility is invisible until it breaks. A screen reader user can't navigate your beautiful UI. WCAG audits catch contrast, keyboard navigation, and ARIA issues before users do.
- AI-generated code has 1.7x more bugs (CodeRabbit 2025). Parallel review by fresh-context reviewers catches over-generation, unnecessary complexity, and slop that original author blindspots miss.
- Runnable tests are usually shallow. LLM suites pass execution but lack strong assertions and edge coverage (VibeCheck, Sep 2026); faults that matter escape because oracles don't assert the failure mode (Hamidi et al., Sep 2026). Green suite ≠ tested behavior — every new test must be observed failing without its fix.
- Interactive features need real interaction. Static analysis can't test loading states, error recovery, or edge cases that only appear in browser.
This protocol is the gate between "I finished coding" and "this is ready to ship."
Decision Tree
Answer these questions to determine which phases to run.
⚠️ E2E-first: Models prioritize unit tests because they seem "easier", but user experience is only guaranteed by E2E tests. This order is intentional: E2E first, unit later.
Feature implemented?
│
├── Has interactive UI (forms, clicks, inputs)?
│ ├── YES → Phase 1 (E2E browser testing)
│ └── NO → Phase 1 (skip — no UI to test)
│
├── Has visual interface?
│ ├── YES → Phase 2 (UI quality audit)
│ └── NO → Phase 2 (skip)
│
├── Has existing unit tests?
│ ├── YES → Phase 3 (run existing suite)
│ └── NO → Phase 3 (skip — create only for critical path)
│
├── Touched 3+ files or critical path?
│ ├── YES → Phase 4 (subagent review)
│ └── NO → Phase 4 (skip, manual review)
│
└── Phase 5 (always — final checklist)
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

stelow-workflow-testing-execution is a skill published in the GitHub repository calionauta/stelow (14 stars, last pushed 9d ago), licensed MIT. It adds 128 tokens to every session and 4,426 once invoked, about $0.0005 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.
