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 | $0.02738 |
| Opus 5 | $0.00023 | $0.01369 |
| Sonnet 5 | $0.00009 | $0.00548 |
| Haiku 4.5 | $0.00005 | $0.00274 |
Grade A, and why
Product Strategist 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 7d 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 — 386 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Product Strategist
Validate that products solve real problems for viable markets before investing in development.
Core Principle
Evidence over intuition. Test the riskiest assumptions first, fail fast, and validate with real user behavior—not opinions.
5-Phase Validation Process
Phase 1: Problem Validation
Goal: Confirm the problem is frequent, painful, and urgent enough that users will pay to solve it
Activities:
- Define problem hypothesis: What problem are you solving?
- Identify target customer segments
- Conduct customer discovery interviews (10-15 per segment)
- Quantify problem severity: time/money cost to users
- Document current workarounds and their pain points
The "Mom Test" Questions:
✅ Good Questions (reveal behavior):
- "Tell me about the last time you encountered [problem]."
- "How are you currently solving this?"
- "How much time/money do you spend on this problem?"
- "What have you tried that didn't work?"
❌ Bad Questions (confirmation bias):
- "Would you use this product?" (Everyone says yes)
- "Do you think this is a good idea?" (Asks opinion, not behavior)
- "How much would you pay for this?" (Hypothetical)
Problem Severity Matrix:
| Dimension | Low (Don't Build) | Medium (Validate More) | High (Build It) |
|---|---|---|---|
| Frequency | Happens rarely | Monthly | Daily/Weekly |
| Impact | Minor annoyance | Wastes 1-2 hours | Critical blocker |
| Urgency | Can wait | Should fix eventually | Need it now |
| Willingness to Pay | Won't pay | Might pay $5-20/mo | Will pay $50+/mo |
| Current Workarounds | Works fine | Tolerable | Painful/expensive |
Decision Rule:
- 4-5 High → Build immediately
- 2-3 High → Validate solution
- 0-1 High → Don't build (problem not severe enough)
What ships with it
2 files 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.

Product Strategist is a skill published in the GitHub repository daffy0208/ai-dev-standards (36 stars, last pushed 8mo ago), licensed MIT. It adds 45 tokens to every session and 2,738 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 2026-09-03.
