What it does
Exit Waterfall is an agent skill from mohitagw15856/pm-claude-skills. Compute who gets what at each exit price from a cap table — liquidation preferences, conversion points, and where the founders' share collapses. Use when asked to model an exit waterfall, what do I get if we sell for X, explain liquidation preferences on my cap table, or compare payouts across exit prices. Produces a per-stakeholder payout table across exit values with conversion decisions shown, plus the plain-English reading of what the structure means for each party.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/worked-example.md` and `scripts/exit_waterfall.py`).
It sits in Business, Finance & HR, covering Financial modeling and Plain language and style rules. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked to model an exit waterfall
- What do I get if we sell for X
- Explain liquidation preferences on my cap table
- Compare payouts across exit prices
Example prompts
- “/exit-waterfall”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Exit Waterfall loads about 1.1k tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 122 tokens; SKILL.md has 516 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.
Safety
Auto-check passed
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); the scripts in this folder are not scanned.

- description
- Compute who gets what at each exit price from a cap table — liquidation preferences, conversion points, and where the founders' share collapses. Use when asked to model an exit waterfall, what do I get if we sell for X, explain liquidation preferences on my cap table, or compare payouts across exit prices. Produces a per-stakeholder payout table across exit values with conversion decisions shown, plus the plain-English reading of what the structure means for each party.
Exit Waterfall Skill
A cap table is a promise about percentages; an exit waterfall is what actually happens to the money. The difference — liquidation preferences, participation, option strikes — routinely stuns founders at the worst possible moment. This skill computes the waterfall across exit prices and, more importantly, translates it: the price below which your shares are worth nothing, and the price where everyone finally converts.
What This Skill Produces
- The payout table — every stakeholder's dollars at each exit price, with conversion decisions shown
- The cliff points — where preferences stop dominating, where options come into the money
- The plain-English reading — "you need a $X exit for your common to mean anything" stated as a sentence
Required Inputs
Ask for these if not provided:
- Share classes — for each: name, share count, type (common / preferred / options); for preferred: amount invested, preference multiple, participating or not; for options: strike
- Exit prices to test — or default to a spread around the last round's valuation (label it as a default)
Programmatic Helper
The math ships as a deterministic script — run it rather than arithmetic-by-hand:
python3 scripts/exit_waterfall.py cap.json
python3 scripts/exit_waterfall.py cap.json --exit 50000000 --jsonInput shape and worked example are in the script docstring. It brute-forces the conversion equilibrium (each non-participating preferred converts only when as-converted beats its preference) and applies the treasury method to options. Stated simplifications: preferences are pari passu (no seniority stacking) and participation is uncapped — flag both when the real cap table differs, and say the numbers shift accordingly.
Formula (readable form)
- Non-participating preferred takes max(preference, as-converted value) — preference = invested × multiple
- Participating preferred takes preference + pro-rata of the remainder (why "participating" is the term sheet word worth fighting)
- Options exercise only when per-share common value > strike; strike proceeds join the pool
- Remainder splits pro-rata among common + converted + participating shares
Output Format
Exit Waterfall: [Company]
Payout Table
[The script's table: exit price × stakeholder, with the converts column]
Show full SKILL.md (212 more words)Show less
What This Means
- Below $[X]: preferences consume everything — common gets zero
- At $[Y]: [class] converts; the structure starts behaving like percentages
- The sentence: "Your [n]% is worth [n]% only above $[Z]; below $[W] it is worth nothing."
Assumptions & Limitations
[Pari passu, uncapped participation, valuation of the classes as supplied — every deviation from the real documents named.]
Educational model, not financial advice — verify with a licensed professional before acting on it.
Quality Checks
- Conversion decisions are computed, not asserted — the table shows who converts at each price
- The zero-for-common threshold is stated explicitly as a price
- Every simplification the model makes vs the real documents is named
- Payouts at each price sum to the exit value (plus/minus rounding)
- The disclaimer line appears in the artifact
Anti-Patterns
- Do not present ownership percentages as payout percentages — the gap between them is this skill's entire reason to exist
- Do not model participation caps or seniority stacking silently — the script doesn't; say so
- Do not average across exit prices — the cliff structure IS the information
- Do not run the numbers without the plain-English sentence — founders remember sentences, not tables
Example Trigger Phrases
- "Model an exit waterfall."
- "What do I get if we sell for X?"
- "Explain liquidation preferences on my cap table."
- "Compare payouts across exit prices."
