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 | $0.00038 | $0.01939 |
| Opus 5 | $0.00019 | $0.00970 |
| Sonnet 5 | $0.00008 | $0.00388 |
| Haiku 4.5 | $0.00004 | $0.00194 |
Grade A, and why
discovery 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.
How it starts
The opening of the file, as written. The whole thing — 369 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Discovery - Business Exploration
Persona
Read .claude/roles/specifier.md — adopt this profile and follow all its rules.
Philosophy
Discovery comes BEFORE specs. We explore:
- The problem — not the solution
- The users — their pain points, not their requests
- The value — the benefit, not the feature
"Fall in love with the problem, not the solution." — Uri Levine
Activation
This skill activates when the user wants to explore:
- "I want to explore...", "What problem are we solving?"
- "Who are the users?", "Discovery on..."
- "What is the value proposition?"
- "Lean canvas for...", "Persona of..."

PROBLEM STATEMENT - Exploration
I see: [vague description of the problem]
Let's dig deeper:
1. Who exactly has this problem?
2. When/where does it manifest?
3. What do they do today to work around it?
4. What is the consequence if we don't solve it?
Answer what resonates, we'll iterate.

# Problem Statement: [Explicit title]
## The problem
[Persona] encounters [problem] when [context/trigger].
Today, [persona] [current behavior / workaround].
This causes [negative consequence] and [measurable impact].
## Frequency and severity
| Dimension | Assessment |
|-----------|------------|
| Frequency | [daily/weekly/monthly/occasional] |
| Severity | [blocking/hindering/irritating] |
| Affected population | [estimate] |
## Hypotheses to validate
- [ ] [Hypothesis about the existence of the problem]
- [ ] [Hypothesis about frequency]
- [ ] [Hypothesis about impact]
## What the problem is NOT
- [Red herring 1 — why it's a red herring]
- [Red herring 2]
## Research questions
- [Open question to explore]
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 is a skill published in the GitHub repository DGouron/review-flow (42 stars, last pushed today), licensed MIT. It adds 38 tokens to every session and 1,939 once invoked, about $0.0002 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.
