agents-reverse-engineer: Command for Claude Code

Quick mode is the same system with a shorter path:

• Spawns gsd-planner (quick mode) + gsd-executor(s)
• Skips gsd-phase-researcher, gsd-plan-checker, gsd-verifier
• Quick tasks live in .planning/quick/ separate from planned phases
• Updates STATE.md "Quick Tasks Completed" table (NOT ROADMAP.md)

Use when: You know exactly what to do and the task is small enough to not need research or verification.

<execution_context> Orchestration is inline - no separate workflow file. Quick mode is deliberately simpler than full GSD. </execution_context>

Read model profile for agent spawning:

MODEL_PROFILE=$(cat .planning/config.json 2>/dev/null | grep -o '"model_profile"[[:space:]]*:[[:space:]]*"[^"]*"' | grep -o '"[^"]*"$' | tr -d '"' || echo "balanced")

Default to "balanced" if not set.

Model lookup table:

Agent	quality	balanced	budget
gsd-planner	opus	opus	sonnet
gsd-executor	opus	sonnet	sonnet

Store resolved models for use in Task calls below.

Step 1: Pre-flight validation

Check that an active GSD project exists:

if [ ! -f .planning/ROADMAP.md ]; then
  echo "Quick mode requires an active project with ROADMAP.md."
  echo "Run /gsd:new-project first."
  exit 1
fi

If validation fails, stop immediately with the error message.

Quick tasks can run mid-phase - validation only checks ROADMAP.md exists, not phase status.

Step 2: Get task description

Prompt user interactively for the task description:

AskUserQuestion(
  header: "Quick Task",
  question: "What do you want to do?",
  followUp: null
)

Store response as $DESCRIPTION.

If empty, re-prompt: "Please provide a task description."

Generate slug from description:

slug=$(echo "$DESCRIPTION" | tr '[:upper:]' '[:lower:]' | sed 's/[^a-z0-9]/-/g' | sed 's/--*/-/g' | sed 's/^-//;s/-$//' | cut -c1-40)

---

Step 3: Calculate next quick task number

Ensure .planning/quick/ directory exists and find the next sequential number:

# Ensure .planning/quick/ exists
mkdir -p .planning/quick

# Find highest existing number and increment
last=$(ls -1d .planning/quick/[0-9][0-9][0-9]-* 2>/dev/null | sort -r | head -1 | xargs -I{} basename {} | grep -oE '^[0-9]+')

if [ -z "$last" ]; then
  next_num="001"
else
  next_num=$(printf "%03d" $((10#$last + 1)))
fi

---

Step 4: Create quick task directory

Create the directory for this quick task:

QUICK_DIR=".planning/quick/${next_num}-${slug}"
mkdir -p "$QUICK_DIR"

Report to user:

Creating quick task ${next_num}: ${DESCRIPTION}
Directory: ${QUICK_DIR}

Store $QUICK_DIR for use in orchestration.

---

Step 5: Spawn planner (quick mode)

Spawn gsd-planner with quick mode context:

Task(
  prompt="
<planning_context>

**Mode:** quick
**Directory:** ${QUICK_DIR}
**Description:** ${DESCRIPTION}

**Project State:**
@.planning/STATE.md

</planning_context>

<constraints>
- Create a SINGLE plan with 1-3 focused tasks
- Quick tasks should be atomic and self-contained
- No research phase, no checker phase
- Target ~30% context usage (simple, focused)
</constraints>

<output>
Write plan to: ${QUICK_DIR}/${next_num}-PLAN.md
Return: ## PLANNING COMPLETE with plan path
</output>
",
  subagent_type="gsd-planner",
  model="{planner_model}",
  description="Quick plan: ${DESCRIPTION}"
)

After planner returns:

1. Verify plan exists at ${QUICK_DIR}/${next_num}-PLAN.md
2. Extract plan count (typically 1 for quick tasks)
3. Report: "Plan created: ${QUICK_DIR}/${next_num}-PLAN.md"

If plan not found, error: "Planner failed to create ${next_num}-PLAN.md"

Step 6: Spawn executor

Spawn gsd-executor with plan reference:
