startup-problem-ledger

startup-problem-ledger is a skill for Claude Code from forjd/startup-ideation-skills. It costs 31 tokens per session (1,594 once invoked), scanned A, original, MIT.

A worksheet for turning a raw annoyance, repeated task, complaint, or market gap into a specific startup problem statement. It records who feels the problem, when it happens, current workarounds, and what the problem costs.

In plain words
What is it for?
Use it to capture customer pain, assess whether it could support a startup, ask the most useful follow-up questions, and choose the next validation step.
Why use it?
It keeps early startup work focused on a real and testable problem instead of jumping straight to a product idea. Unknown information is marked as unknown rather than guessed.

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

startup-problem-ledger 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.

Startup Problem Ledger

When to use

Use when the user notices an annoyance, repeated manual task, customer complaint, internal workflow issue, market inefficiency, product idea, or asks whether something could be a business.

Do not start by designing the product. First log the observation, sharpen the problem, and check whether it is startup-shaped.

Core rule

Keep the user anchored on the pain, the person feeling it, the moment it happens, the workaround, and the cost. Avoid turning every frustration into a SaaS idea by default.

Workflow

  1. Capture the raw observation in the user's words.
  2. Fill the problem ledger using only known information.
  3. Mark unknowns as Unknown, not guessed facts.
  4. Sharpen the vague pain into one or more specific problem statements.
  5. Screen for whether the problem is painful, specific, timely, underserved, founder-fit, and expandable.
  6. Ask only the highest-value missing questions first. Prefer 3–5 questions, not a giant form.
  7. Decide whether the entry is Startup-shaped, Unclear, or Probably not.
  8. Suggest the next validation step, not a product roadmap.
  9. Produce or update the shared evidence packet so later skills inherit the same facts, unknowns, and decision gate.

Problem ledger

Use this format:

Raw observation:
Context:
Who experienced it:
Where/when it happened:
Problem:
User/persona:
Job they are trying to do:
Obstacle:
Current workaround:
Cost of doing nothing:
Frequency:
Emotional intensity:
Potential buyer:
Existing tools/alternatives:
Why now:
Founder advantage:
Distribution route:
Expansion path:
Could I reach 10 users:
Could I build v1 in 2–4 weeks:
Startup-shaped: yes/no/unclear
Next validation step:

Opportunity screen

Check these properties before calling something startup-shaped:

Painful: expensive, frequent, embarrassing, risky, or intensely annoying.
Specific: exact customer and exact situation are nameable.
Timely: a recent change makes solving it newly possible or urgent.
Underserved: alternatives are absent, bloated, expensive, slow, or misaligned.
Founder-fit: the founder has relevant skill, access, credibility, or obsession.
Expandable: the first niche can grow into adjacent workflows, budgets, or markets.

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.
