At a glance

Reference and evaluator for SaaS unit economics and capital efficiency: gross margin, CAC, LTV, burn, runway and magic number, to decide whether to scale or optimize.

  • Works in 4 steps: Calculate Unit Economics → Calculate Capital Efficiency → Calculate Efficiency Ratios → …
  • Checking whether the business can scale efficiently or needs correction
  • SKILL.md covers Purpose, Input, Key Concepts and Application, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

The skill is a framework for product managers rather than a finance reporting tool, covering unit economics, profitability and cash runway. Its unit economics section defines gross margin, CAC and LTV with formulas, what each one includes, why PMs care and rough benchmarks, such as a SaaS gross margin of 70 to 85 percent being good and under 60 percent concerning, and enterprise CAC of 10K and up being acceptable while SMB targets sit under 500.

You state the question, such as whether you can scale, raise or extend runway, or list the metrics to evaluate, for instance CAC, gross margin, burn, runway and magic number. Partial data works, and with no input the skill serves as a reference organized by stage and decision. A template and two examples are included, one of healthy unit economics and one of a cash trap.

When your agent uses it

  • Checking whether the business can scale efficiently or needs correction
  • Preparing unit economics and runway numbers for fundraising or board reporting
  • Learning how gross margin, CAC and LTV are calculated and benchmarked

Example prompts

  • “Are we efficient enough to scale? CAC $9K, gross margin 72%, burn multiple 2.1, magic number 0.6.”
  • “Explain how CAC and LTV should be calculated for our usage-based SaaS.”
  • “Is our runway short enough that we should prioritize efficiency over growth?”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Calculate Unit Economics
  2. Calculate Capital Efficiency
  3. Calculate Efficiency Ratios
  4. Analyze by Segment and Channel

What it can do on your machine

Read from SKILL.md and the folder at commit 1b5a524. 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

    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.

  • 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

SaaS Economics and Efficiency Metrics loads about 6.4k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 3,025 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~6.4k

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); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,025 words (~6,434 tokens).

“Determine whether your SaaS business model is fundamentally viable and capital-efficient. Use this to calculate unit economics, assess profitability, manage cash runway, and decide when to scale vs. optimize. Essential for fundraising, board reporting, and making smart investment trade-offs.”
