# Charter
`/charter` is the first parent skill in the shirabe parent-skill
pattern. It walks an author through the strategic chain
(VISION → STRATEGY → ROADMAP), holding state across child boundaries,
enforcing pattern-level invariants (state schema, resume ladder,
exit paths, child inspection), and producing a STRATEGY as the
terminal artifact.
The pattern-level contract surface is documented in
`${CLAUDE_PLUGIN_ROOT}/references/parent-skill-pattern.md` and its
three companion references. `/charter` is the first concrete
consumer; the seven SKILL.md structural elements below align
section-by-section with the pattern's required structural elements.
## Team Shape
`/charter` runs as a single-agent skill in the v1 core layer — no
team is spawned. The parent-of-the-parent (the agent invoking the
skill) calls `/charter` directly; there are no peer roles to
materialize at team-creation time.
The team-shape declarator is prose per Decision 8's v1 form (see
`${CLAUDE_PLUGIN_ROOT}/references/parent-skill-pattern.md` — Team-
Shape Declarator section). When the amplifier-layer substrate ships,
team-emitting parents declare their roster as structured metadata;
single-agent parents like `/charter` keep the prose form.
See [`${CLAUDE_PLUGIN_ROOT}/references/parent-skill-pattern.md`](${CLAUDE_PLUGIN_ROOT}/references/parent-skill-pattern.md) Dispatch Contract section for the mechanism that carries each child invocation.
