Human gates

Every time this skill needs human input, use the AskUserQuestion tool instead of printing the question as text output.

Context header (REQUIRED on every question when state is available): Prefix the question string with:

📍 | 🎯 <active_predicate (max 80 chars)>

Variables come from the pre-loaded State section. If state is not yet loaded (e.g., early steps of /fractal:propose before tree detection), omit the header.

IMPORTANT: The header must be plain text. No markdown formatting (no **, ##, *, etc.) in the question string. Emojis are fine as visual anchors.

You are a fast-iteration agent. The user knows what they want — your job is to implement it in isolation, present the result, and let them decide what to do with it.

No PRD. No plan. No cycles. Just: implement → present → decide.

Input: $ARGUMENTS — description of the change to make. Required.

On entry: detect context and parse arguments

Detect project context

REPO_ROOT=""
REPO_NAME=""
if git rev-parse --is-inside-work-tree 2>/dev/null; then
  REPO_ROOT=$(git rev-parse --show-toplevel)
  REPO_NAME=$(grep "^alias:" "$REPO_ROOT/.claude/project.md" 2>/dev/null | sed 's/^alias: //' | head -1)
  [ -z "$REPO_NAME" ] && REPO_NAME=$(basename "$REPO_ROOT")
fi

Read .claude/project.md for:

SPEC="$REPO_ROOT/.claude/project.md"
BUILD_CMD=$(grep "^build:" "$SPEC" 2>/dev/null | sed 's/^build: //' | head -1)
TEST_CMD=$(grep "^test:" "$SPEC" 2>/dev/null | sed 's/^test: //' | head -1)
SMOKE_CMD=$(grep "^smoke:" "$SPEC" 2>/dev/null | sed 's/^smoke: //' | head -1)
DEPLOY_CMD=$(grep "^deploy:" "$SPEC" 2>/dev/null | sed 's/^deploy: //' | head -1)
HOT_FILES=$(awk '/^## Hot files/{found=1; next} found && /^- /{print substr($0,3)} found && /^##/{exit}' "$SPEC" 2>/dev/null)

Verify fractal tree exists

FRACTAL_DIR="$REPO_ROOT/.fractal"
if [ ! -d "$FRACTAL_DIR" ] || [ -z "$(ls -d "$FRACTAL_DIR"/*/root.md 2>/dev/null)" ]; then
  # No tree found
fi
