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 | $0.00045 | $0.01761 |
| Opus 5.5 | $0.00018 | $0.00704 |
| Sonnet 5.5 | $0.00009 | $0.00352 |
| Haiku 4.5 | $0.00005 | $0.00176 |
Grade A, and why
exploratory-testing-advanced 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 8d 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.

Advanced Exploratory Testing
<default_to_action> When exploring software or investigating quality risks:
- CREATE charter with mission, scope, and time-box (45-90 min)
- APPLY heuristics: SFDIPOT (quality criteria), FEW HICCUPPS (consistency oracles)
- EXPLORE systematically using test tours (Business District, Bad Neighborhood, Historical)
- DOCUMENT findings in real-time with notes, screenshots, evidence
- DEBRIEF: What learned? What's next? Share via agent memory
Quick Heuristic Selection:
- What to test → SFDIPOT (Structure, Function, Data, Interfaces, Platform, Operations, Time)
- Recognize problems → FEW HICCUPPS (Familiar, Explainable, World, History, Image, Comparable, Claims, Users, Product, Purpose, Standards)
- Navigate app → Test Tours (12 types for different exploration strategies)
Critical Success Factors:
- Exploration is skilled, structured thinking - not random clicking
- Document discoveries, not pre-planned test cases
- Pair testing reveals more than solo exploration </default_to_action>
Quick Reference Card
When to Use
- Investigating new or changed features
- Finding bugs automation misses
- Learning unfamiliar systems
- Risk discovery before test planning
Session Structure (SBTM)
| Phase | Duration | Activity |
|---|---|---|
| Charter | 5 min | Define mission, scope, focus |
| Explore | 45-75 min | Systematic investigation |
| Note | Continuous | Document findings real-time |
| Debrief | 10-15 min | Summarize, prioritize, share |
SFDIPOT Heuristic (What to Test)
| Letter | Focus | Example Questions |
|---|---|---|
| Structure | Is it properly composed? | Code structure, UI layout, data schema |
| Function | Does it do what it should? | Core features work correctly |
| Data | Handles data correctly? | CRUD, validation, persistence |
| Interfaces | Interacts well? | APIs, UI, integrations |
| Platform | Works in environment? | Browsers, OS, devices |
| Operations | Can be used/managed? | Install, config, monitor |
| Time | Handles timing? | Concurrency, timeouts, scheduling |
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.

exploratory-testing-advanced is a skill published in the GitHub repository proffesor-for-testing/agentic-qe (505 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 1,761 once invoked, about $0.0002 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 2026-10-11.
