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 | $0.00042 | $0.00988 |
| Opus 5 | $0.00021 | $0.00494 |
| Sonnet 5 | $0.00008 | $0.00198 |
| Haiku 4.5 | $0.00004 | $0.00099 |
Grade A, and why
defining-product-vision 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 12d 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.

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Defining Product Vision
Help the user create compelling product visions using frameworks from 101 product leaders who have defined visions at companies from Notion to Airbnb to the New York Times.
How to Help
When the user asks for help with product vision:
- Clarify the scope - Determine if they need a vision (long-term aspiration), strategy (how to win), or roadmap (what to build)
- Focus on the user's future - Help them describe the world 5-10 years out, not the product features
- Test for specificity - Push back on vague taglines that don't change behavior
- Make it visual - Encourage prototypes and concrete artifacts over abstract documents
Core Principles
Vision is not a tagline
Melissa Perri: "I once asked all the executive team at a healthcare company, what's the vision for this company? And they said, to be the backbone of healthcare. And I said, what does that mean? And they couldn't elaborate." A vision must be a concrete description of what the company will manifest in 5-10 years.
Four criteria for strong vision
Ebi Atawodi: "It has to be lofty, it has to be realistic, it has to be devoid of any tech or limitations of today, and it has to be grounded in a very clear and potent problem." Balance aspiration with attainability while ignoring current technical constraints.
Hide radical vision in familiar utility
Ivan Zhao (Notion): "Our realization is actually let's hide our vision, which is everybody can create their software, in the form factor that people do care. So what kind of tool do people use every day? Productivity software." Package a radical long-term vision inside a familiar, high-utility form factor.
Vision describes the user's world, not your product
Ben Williams: "The vision is the nirvana state that you aim to enable for your users and customers in five to 10 years... It should not mention your company, your product, or anything solution related at all." Prefix vision statements with 'In the future...' to maintain long-term focus.
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.

defining-product-vision is a skill published in the GitHub repository cnfeat/top-pm-skills (48 stars, last pushed 3mo ago), licensed MIT. It adds 42 tokens to every session and 988 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.
