Marketplace Liquidity Take Rates is an agent skill from RefoundAI/lenny-skills. Help users define precise liquidity metrics, set competitive take rates based on value delivery, and manage the delicate balance between supply-side health and platform profitability.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/artifacts.md` and `references/guest-insights.md`).
The repository describes itself as: 86 product management skills from Lenny's Podcast for Claude Code and AI agents. Hiring, user research, strategy, shipping, and more. The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 13598cc. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Marketplace Liquidity Take Rates loads about 1.9k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 1,093 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Help the user with marketplace liquidity and take rates using insights from 6 guests and posts across Lenny's Podcast and Newsletter.
Dan Hockenmaier: "For a marketplace, you're like messing with this ecosystem that you don't actually really understand how it works. And sometimes you might do something over here which drives this long-term effect two months later, and then you're going to be pulling your hair out two months later trying to figure out what you did over here that made that thing happen."
Marketplace health depends on complex interactions where small changes cause delayed ripple effects. Leaders should use a light touch and monitor downstream impacts for months after making changes.
From "Choosing a take rate": "Differences in take rates are primarily driven by three factors: (1) whether you can drive new demand, (2) how much convenience you provide the seller, and (3) the level of competition in the market."
Your fee should reflect the new demand you generate and the operational ease you provide. Start with a 10% baseline for platforms and 20% for marketplaces, then adjust based on product value.
From "Choosing a take rate": "The most dangerous strategy for any platform company is to price too high – to charge a greedy and overzealous rake that could serve to undermine the whole point of having a platform in the first place."
High take rates create friction and leave room for competitors to undercut you. Lower rates can secure a long-term edge in winner-take-all markets by reducing barriers to transaction.
From "The most important marketplace metrics to track": "Since there’s so much confusion around this term, I prefer to avoid using it altogether when we’re describing operational metrics, and instead get specific about what I mean (e.g. fill rate, supply quantity, supply success, etc.). If you do use it, explain what you actually mean. Don’t assume anyone knows what you’re talking about when you say ‘liquidity.’"
The term liquidity is too ambiguous for daily operations. Replace it with specific metrics like fill rate or success rate to ensure the team is aligned on what a successful match looks like.
From "Why marketplaces fail": "The most fundamental job of a marketplace is to efficiently match supply with demand. If you can’t do this reliably (i.e. fill-rate) or quickly (i.e. time-to-match), you’ll fail."
Users will abandon a platform for more reliable alternatives if they experience low fill rates or slow matching times. Prioritize providing high certainty of a match over broad expansion.
From "The inside story of Facebook Marketplace": "Once we had the tab within the Facebook app to drive buyer engagement, we settled on the key metric of weekly buyer retention."
Focusing on demand-side retention ensures the marketplace provides repeatable value rather than temporary growth. Set weekly buyer retention as your north star metric for product-market fit.
From "Choosing a take rate": "Companies like Upwork, Patreon, StockX, Doordash, Uber Eats, and Grubhub take advantage of The Take Rate Formula by offering different take rates for more or less Convenience and Demand."
Tiered pricing allows you to map different take rates to the specific level of service each seller needs. Use volume-based tiers to reward your most active participants while capturing value from others.
