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 | $0.00085 | $0.00903 |
| Opus 5 | $0.00043 | $0.00451 |
| Sonnet 5 | $0.00017 | $0.00181 |
| Haiku 4.5 | $0.00009 | $0.00090 |
Grade B, and why
product-wisdom scanned grade B with 1 finding 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 11d 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.
Strips warnings and disclaimersmediumAnti-refusal
Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

Product Wisdom
Condensed insights from top product leaders. Apply these frameworks when helping with product decisions.
Core Frameworks
Activation: Get Users to Value Fast
The magic moment matters more than features. Find yours:
- Slack: 2,000 messages exchanged = team is hooked
- Gamma: 30 seconds to first presentation = user activated
Apply when: Discussing onboarding, retention, or "users aren't sticking"
Positioning (April Dunford's 5 Steps)
Start with competitive alternatives, not messaging:
- What would customers use if you didn't exist?
- What's your unique capability?
- What value does that capability enable?
- Who cares most about that value?
- What market context makes this obvious?
Apply when: Go-to-market, messaging, or "how do we differentiate"
Product Discovery (Teresa Torres + Marty Cagan)
Talk to customers weekly, not quarterly. Use Opportunity Solution Trees:
- Desired outcome → Opportunities → Solutions → Experiments
Validate Four Risks before building:
- Value risk: Will customers buy/use it?
- Usability risk: Can they figure it out?
- Feasibility risk: Can we build it?
- Viability risk: Does it work for our business?
Apply when: Deciding what to build, validating ideas
Prioritization (Shreyas Doshi's LNO)
Categorize tasks by type, not just impact:
- Leverage: 10x returns, deserves 10x effort
- Neutral: Standard work, standard effort
- Overhead: Minimize time, just get it done
Focus on opportunity cost, not ROI. What are you NOT doing?
Apply when: Roadmap planning, sprint planning, "we can't do everything"
Team Structure
Give teams problems to solve, not features to build. Empowered teams vs. feature factories.
Small teams win: Jason Fried's 2-person/6-week constraints. Shopify's pair programming. Companies produce MORE after layoffs—coordination overhead is the silent killer.
Apply when: Team org, hiring decisions, "we need more people"
Pre-Mortems (Shreyas Doshi)
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-wisdom is a skill published in the GitHub repository stonegiantstudio/skills (2 stars, last pushed 6d ago), licensed Apache-2.0. It adds 85 tokens to every session and 903 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (strips warnings and disclaimers). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
