At a glance

Frames an epic as a testable if-then hypothesis with a target user, expected outcome, small discovery experiments and validation measures.

  • Works in 6 steps: Gather Context → Draft the If/Then Hypothesis → Design Tiny Acts of Discovery Experiments → …
  • Defining a major initiative before roadmap or discovery planning
  • SKILL.md covers Purpose, Input, Key Concepts and Application, plus 3 more sections
  • Reaches github.com

What it does

The skill turns an initiative into a hypothesis rather than a requirements spec. The structure is: if we take an action or build a solution for a target persona, then we will reach a desirable outcome or job-to-be-done. It adds lightweight experiments called tiny acts of discovery, plus validation measures that state a timeframe and the quantitative and qualitative results that would show the hypothesis holds.

A sentence about the initiative is enough as input, and anything you supply with the invocation counts as already answered, so the agent skips those questions. With nothing supplied it asks what the initiative is and who it is for, then builds the hypothesis with you. The format is credited to Tim Herbig's Lean UX hypothesis approach. It lists anti-patterns, such as a feature spec like building a dashboard with five charts, and ships a template plus two worked examples, one of them industrial.

When your agent uses it

  • Defining a major initiative before roadmap or discovery planning
  • Turning a feature idea into a testable bet with success criteria
  • Choosing lightweight experiments before committing to a full build

Example prompts

  • “Frame as an epic hypothesis: usage-based alerts so account admins catch overages before the invoice arrives.”
  • “Help me turn 'redesign onboarding' into a testable epic with validation measures.”
  • “Write the epic hypothesis for letting plant managers schedule maintenance from a tablet.”

Workflow steps

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

  1. Gather Context
  2. Draft the If/Then Hypothesis
  3. Design Tiny Acts of Discovery Experiments
  4. Define Validation Measures
  5. Run Experiments and Evaluate
  6. Convert to User Stories (If Validated)

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 (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    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

Epic Hypothesis Framing loads about 3.2k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 1,360 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~3.2k

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.
