runway-forecast is a skill for Claude Code, Codex from msolecki/founder-os. It costs 30 tokens per session (2,258 once invoked), scanned A, original, MIT.

A monthly calculation of how long a company can keep operating using its available cash and real spending rate, with future sales reduced by pipeline stage.

In plain words
What is it for?
Use it after a monthly revenue review and before commitments such as tools, contractors, subscriptions, or time off.
Why use it?
It prevents spending decisions from being based on optimistic sales assumptions or on a founder’s unpaid salary.

Token cost

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.

Security

Grade A, and why

runway-forecast 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 9d 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.

Runway Forecast

Runway is the number that converts every other decision from a preference into arithmetic. It is also the number founders compute with their own salary left out — which is how a company that is quietly insolvent appears to have eight months.

When to use

Monthly, right after revenue-review. Before any commitment that changes burn: a tool, a contractor, a subscription, a month off. Whenever the founder asks whether they can afford something.

First-run branch

Use this branch only when /founder-os-init invokes the skill and the ## Close block carries Close type: activation-baseline. The first-run question is narrower than the recurring forecast: what can be computed from supplied cash and real burn on YYYY-MM-DD without turning an absent pipeline into revenue?

Input state Persisted result Required action
cash and burn supplied Honest runway from cash divided by real monthly burn that is strictly greater than zero. Compute the dated runway on YYYY-MM-DD with zero new revenue; use only the supplied cash and positive burn.
zero burn Runway: not finite at the current zero-burn state. Do not divide, write no cliff date and no band, and state that zero burn must be verified before any spending decision.
negative burn Runway: UNKNOWN because a negative outflow is an invalid burn input. Do not divide, write no cliff date and no band, and hand the classification gap to the Chief of Staff for the queue.
cash unknown Runway: UNKNOWN Write no band and no cliff date; hand the cash evidence gap to the Chief of Staff for the queue.
burn unknown Runway: UNKNOWN Write no band and no cliff date; hand the real-burn evidence gap to the Chief of Staff for the queue.
pipeline unknown Pipeline-discounted runway: UNKNOWN Never zero-fill pipeline and write no optimism gap; the honest runway remains valid when cash and burn exist.

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.
