Manual Plan-Sync

Manually trigger plan-sync to update downstream task specs.

CRITICAL: flowctl is BUNDLED — NOT installed globally. Always use:

CopyROOT="$(git rev-parse --show-toplevel)"
OPENCODE_DIR="$ROOT/.opencode"
FLOWCTL="$OPENCODE_DIR/bin/flowctl"

Input

Arguments: $ARGUMENTS Format: <id> [--dry-run]

• <id> - task ID (fn-N.M) or epic ID (fn-N)
• --dry-run - show changes without writing

Workflow

Step 1: Parse Arguments

CopyROOT="$(git rev-parse --show-toplevel)"
OPENCODE_DIR="$ROOT/.opencode"
FLOWCTL="$OPENCODE_DIR/bin/flowctl"

Parse $ARGUMENTS for:

• First positional arg = ID
• --dry-run flag = DRY_RUN (true/false)

Get cross-epic config (defaults to false):

CopyCROSS_EPIC="$($FLOWCTL config get planSync.crossEpic --json 2>/dev/null | jq -r '.value // empty')"
if [[ -z "$CROSS_EPIC" || "$CROSS_EPIC" == "null" ]]; then
  CROSS_EPIC="false"
fi

Validate ID format:

• Must start with fn-
• If no ID: "Usage: /flow-next:sync [--dry-run]"
• If invalid: "Invalid ID format. Use fn-N (epic) or fn-N.M (task)."

Detect ID type:

• Contains . (e.g., fn-1.2) → task ID
• No . (e.g., fn-1) → epic ID

Step 2: Validate Environment

Copytest -d .flow || { echo "No .flow/ found. Run flowctl init first."; exit 1; }

If .flow/ missing, output error and stop.

Step 3: Validate ID Exists

Copy$FLOWCTL show <ID> --json

If fails:

• Task: "Task not found. Run flowctl list to see available."
• Epic: "Epic not found. Run flowctl epics to see available."

Stop on failure.

Step 4: Find Downstream Tasks

For task ID input:

Copy# Extract epic from task ID
EPIC=$(echo "<task-id>" | sed 's/\.[0-9]*$//')

# Get all tasks in epic
$FLOWCTL tasks --epic "$EPIC" --json

Filter to status: todo or status: blocked. Exclude source task.

For epic ID input:

Copy$FLOWCTL tasks --epic "<epic-id>" --json

1. Find source task (agent requires COMPLETED_TASK_ID):

   • Prefer most recently updated task with status: done
   • Else: most recently updated with status: in_progress
   • Else: error "No completed or in-progress tasks to sync from."

2. Filter remaining to status: todo or status: blocked (downstream).

If no downstream tasks:

CopyNo downstream tasks to sync (all done or none exist).

Stop (success).

Step 5: Spawn Plan-Sync Agent

Build context and spawn via Task tool:

CopySync task specs from <source> to downstream tasks.

COMPLETED_TASK_ID: <source task id>
FLOWCTL: $OPENCODE_DIR/bin/flowctl
EPIC_ID: <epic id>
DOWNSTREAM_TASK_IDS: <comma-separated list>
DRY_RUN: <true|false>
CROSS_EPIC: <true|false>

<if DRY_RUN>
DRY RUN MODE: Report changes but do NOT edit files.
</if>

Use Task tool with subagent_type: flow-next:plan-sync

Step 6: Report Results

Normal mode:

CopyPlan-sync: <source> -> downstream tasks

Scanned: N tasks (<list>)
<agent summary>

Dry-run mode:

CopyPlan-sync: <source> -> downstream tasks (DRY RUN)

<agent summary>

No files modified.

Error Messages

Rules

• Ignores config - planSync.enabled is for auto-trigger; manual always runs
• Any source status - source can be todo, in_progress, done, or blocked
• Includes blocked - downstream includes both todo and blocked tasks
• Reuses agent - spawns plan-sync agent, no duplication
