Lenny Skills is a collection of product-management and engineering workflows for Claude Code and other AI agents, covering areas such as strategy, research, planning, shipping, growth, and hiring. Each skill gives an agent specialized guidance, frameworks, checklists, or templates for product work, and the catalogue contains many of these skills.
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.

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 | $0.00030 | $0.01565 |
| Opus 5 | $0.00015 | $0.00783 |
| Sonnet 5 | $0.00006 | $0.00313 |
| Haiku 4.5 | $0.00003 | $0.00156 |
Grade A, and why
founder-psychology 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 13d 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.

Founder Psychology and Resilience
Mastering the internal landscape to sustain high performance and navigate the emotional roller coaster of leadership.
Help the user with founder psychology and resilience using insights from 25 guests and posts across Lenny's Podcast and Newsletter.
How to Help
- Diagnose internal state - Use physical and behavioral signals to identify stress or burnout before they escalate into a crisis.
- Practice radical self-inquiry - Investigate the childhood motivations and emotional wounds that drive current professional behaviors and ambition.
- Reframe setbacks - Transform imposter syndrome and failure into positive signals of growth and objective learning data.
- Regulate physiology - Apply somatic techniques to calm the nervous system and ensure clear decision-making under high pressure.
Core Principles
Biological Signal Monitoring
Andy Johns: "It's like when their fundamental functions, when their core behaviors of diet, exercise, playfulness, socialization, sleep, when those things get disrupted, it's a sign that there is something going on here that you need to take a look at. ... If your sleep always sucks, if your relationships are constantly strained or frequently strained, if your physical health is failing, there's so many ways that that can be measured."
Monitor core functions like sleep, diet, and exercise as the first line of defense; their breakdown is the primary signal of approaching burnout.
Irrational Commitment
Dalton Caldwell: "There has to be this irrational intention to keep going even when the world tells you it's not working and you feel completely defeated. And you likely have to go through this many times and have these near-death experiences. And then you get lucky and then you look like an overnight success."
Success often requires a mindset of just don't die and an irrational commitment to keep going despite multiple near-death experiences.
Radical Self-Inquiry
Jerry Colonna: "And so, the equation is practical skills plus radical self-inquiry plus shared experiences, that is the process of actually talking about the craziness that goes on in your head equals greater leadership."
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.

founder-psychology is a skill published in the GitHub repository RefoundAI/lenny-skills (1,321 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 1,565 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.
