+name: auto-feature
+description: >
+  Derive the missing work of a codebase and turn it into requirement
+  documents: a sceptic pass for what the code gets structurally wrong, a
+  usability pass for what the product does not do yet, then active-listening
+  to confirm every proposal through single-select (radio button) questions
+  before anything is written. Trigger on /auto-feature, "was fehlt noch",
+  "welche features brauchen wir", or when the operator asks what to build
+  next. Portable across projects.
+---
+
+Two blind spots produce different work: the code has defects of structure,
+the product has gaps of use. This skill runs both lenses, ranks what comes
+out, and lets the operator choose — it writes requirement documents, never
+implementations.
+
+## Step 1: fix the scope
+
+Name the target in one line: repository, subsystem, role, or user-facing
+surface. Read the project's existing requirement documents first — their
+location, filename convention, and section structure are the template, and
+an already-written requirement is not a finding.
+
+## Step 2: the sceptic pass
+
+Invoke the `sceptic` skill on the target. Its findings become requirement
+candidates by severity: a violated SPOT, SRP, or trust boundary is work the
+product needs whether or not a user ever notices. Carry each finding's
+`file:line` evidence forward — a requirement without it is a guess.
+
+## Step 3: the usability pass
+
+Independently, look for what the product does not do yet. Anchor every gap
+in something observable in the repository, never in an invented persona:
+
+- **Entry** — can someone install, configure, and run it without reading the
+  source? Missing `--help`, missing example config, an undocumented required
+  variable.
+- **Recovery** — does a failure tell the user what to do next? Errors that
+  print a stack trace instead of the remediation, no dry-run, no way to undo
+  or uninstall, no idempotent re-run.
+- **Feedback** — does a long operation say anything while it works? Silent
+  minutes, no progress, no exit summary.
+- **Empty and edge states** — first run with no data, zero results, an
+  expired credential, a partially completed run.
+- **Discoverability** — a capability that exists but nothing surfaces:
+  undocumented flags, features reachable only by reading tests.
+- **Accessibility and locale** — output that assumes colour, a terminal
+  width, or one language.
+
+Each gap gets one line: `observed evidence -> who is blocked -> smallest
+change that unblocks them`. Drop anything you cannot anchor.
+
+## Step 4: rank and ask
+
+Merge both lists, drop duplicates where a structural finding and a usability
+gap describe the same defect, and rank by blocked users first, blast radius
+second.
+
+Then apply `active-listening`: answer everything you can from the code, the
+docs, and the git history yourself, and put only the genuinely open decisions
+to the operator with `AskUserQuestion`, `multiSelect: false`, so every
+question renders as radio buttons. At most four questions per call, each
+option a real alternative — never one option plus filler:
+
+1. **Which candidates** become requirements this run, ranked, each option
+   carrying its evidence in the description.
+2. **Which shape** the chosen one takes — for a feature typically
+   `Minimal version that unblocks the user`, `Full version`, `Fix the
+   underlying structure instead`, `Document the limitation and defer`.
+3. **Scope boundary** — what is explicitly out of scope, when the candidate
+   could grow in more than one direction.
+4. **Placement** — which requirement file or directory receives it, when the
+   project has more than one.
+
+Never assume an answer, never fold two decisions into one option, and never
+write a file before the answers are in.
+
+## Step 5: write the requirements
+
+One document per feature — a requirement that needs "and" in its title is
+two requirements. Follow the project's existing template; when there is
+none, keep it to: problem with its evidence, the decided scope and its
+boundary, definition of done as checkable criteria, and the alternatives the
+operator rejected with the reason.
+
+Show the drafted document and ask for a final `Write it` / `Revise it` /
+`Discard` before touching disk.
+
+## Rules
+
+- Requirements only: no implementation, no refactor, no staging as part of
+  this skill.
+- Every requirement traces to evidence — a `file:line`, a failing path, a
+  missing artifact. A requirement whose justification is "would be nice" is
+  not written.
+- Record the rejected alternatives inside the document; the next reader
+  needs to know what was already considered and dismissed.
+- Close with the `confidence` skill's numbers for the analysis: how sure the
+  gaps are real, and what the passes did not cover.
