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 | $0.00062 | $0.01784 |
| Opus 5 | $0.00031 | $0.00892 |
| Sonnet 5 | $0.00012 | $0.00357 |
| Haiku 4.5 | $0.00006 | $0.00178 |
Grade A, and why
discovery-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 10d 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

Skill: Discovery Advanced
Load trigger:
"load discovery-advanced skill"> DORA: AI Capability 6 (User-centric focus) Token cost: Medium Prerequisite:discoveryskill must have run first. This skill extends it.
Purpose
When the 15-minute discovery exercise surfaces an assumption too risky to build on
without testing, this skill provides the methods to validate it before writing a line
of code. Designed for a solo entrepreneur with 2hrs/day: every method here fits
inside one session.
When to Use This Skill (not the base discovery skill)
| Situation | Method |
|---|---|
| Riskiest assumption involves user behavior you've never observed | Assumption mapping + lightweight interview |
| Two personas have conflicting needs for the same feature | Persona priority matrix |
| Major capability being designed (new belt module, new golden path) | Jobs-to-be-done interview protocol |
| Previous release didn't get adopted despite solving the stated problem | Assumption autopsy |
| Platform feedback NPS dropped significantly without clear cause | Friction log analysis |
Method 1: Assumption Mapping (20 min)
Surface all assumptions embedded in a proposed change, rank by risk.
## Assumption Map — [FEATURE_NAME]
For each assumption, assess:
- Importance: How critical is this to the feature working? (High/Med/Low)
- Certainty: How confident are we this is true? (High/Med/Low)
- Risk = High importance + Low certainty
| # | Assumption | Importance | Certainty | Risk | Validation method |
| --- | ---------------------------------------------------- | ---------- | --------- | ------- | -------------------- |
| 1 | Users will read the Quick Start before filing issues | High | Low | 🔴 High | Check issue patterns |
| 2 | Docker Compose up works on Mac ARM | High | Med | 🟡 Med | CI matrix test |
| 3 | Users prefer CLI over UI for config | Med | Low | 🟡 Med | Friction log review |
Prioritize: validate 🔴 High-risk assumptions before writing any spec.
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.

discovery-advanced is a skill published in the GitHub repository paruff/uFawkesAI (2 stars, last pushed 18d ago), licensed MIT. It adds 62 tokens to every session and 1,784 once invoked, about $0.0003 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 2026-08-31.
