# Planka <-> OpenSpec Reconciliation Sync
**OpenSpec is the source of truth for all agentic work.** Planka provides a read-only view so humans and other agents can see what's happening. This workflow reads OpenSpec state and reconciles Planka to match.
Runs the `kanban-project-sync` script to reconcile Planka board state with OpenSpec changes.
## Prerequisites
## How It Works
Before syncing, verify connectivity:
The sync is handled by the `kanban-project-sync` bash script (on PATH). It:
1. Checks Planka connectivity
2. Bootstraps project/board/lists/label infrastructure (idempotent)
3. Reads OpenSpec state and maps changes to board lists
4. Creates/moves/updates Planka cards and task checklists
5. Moves orphaned cards to Done
**OpenSpec is the source of truth.** Planka is a read-only projection. Sync is one-directional (OpenSpec -> Planka) and idempotent.
## Running the Sync
Read project config and invoke the script in background mode:
```bash
pcli status
PROJECT_NAME=$(yq -r '.planka.project' project.yaml)
BOARD_NAME=$(yq -r '.planka.board' project.yaml)
kanban-project-sync --project "$PROJECT_NAME" --board "$BOARD_NAME" --background
```
If this fails, skip the Planka sync silently. Planka sync is best-effort - never block agentic work because Planka is unavailable.
The `--background` flag makes the script fire-and-forget — it detaches and logs to `/tmp/kanban-project-sync-<project>-<board>.log`.
---
## Concurrency
## Core Principles
1. **OpenSpec owns the state** - `tasks.md`, artifacts, and change status live in OpenSpec
2. **Planka is a projection** - it reflects OpenSpec state, never the other way around
3. **Sync is one-directional** - OpenSpec -> Planka, never Planka -> OpenSpec
4. **Sync is idempotent** - running it twice produces the same result
5. **Sync is best-effort** - if Planka is down, work continues uninterrupted
6. **Non-agentic work** is managed directly in Planka (no OpenSpec involvement)
---
## When This Runs
This workflow is triggered automatically after any opsx workflow completes (via project-level instruction in `CLAUDE.md`). It can also be invoked manually via `/kanban-sync`.
---
## Board Structure
The board lists map to OpenSpec lifecycle stages:
| List | Position | Purpose |
|------|----------|---------|
| **Backlog** | 1 | Non-agentic work items (human-managed, read-write) |
| **To Do** | 2 | Non-agentic work items ready to start (human-managed, read-write) |
| **Planning** | 3 | OpenSpec changes with artifacts still being created (`opsx:new`, `opsx:continue`, `opsx:ff`) |
| **In Progress** | 4 | Active implementation — tasks being worked (`opsx:apply`) |
| **Review** | 5 | All tasks complete, awaiting verification (`opsx:verify`) |
| **Done** | 6 | Completed and archived (`opsx:archive`) |
---
## Bootstrap: Ensure Project, Board, Lists, and Label Exist
Before reconciling, ensure all required Planka infrastructure exists. This makes the sync self-bootstrapping — running it on a fresh Planka instance will create everything needed.
### 1. Read project config
```bash
PROJECT_NAME=$(yq '.planka.project' project.yaml)
BOARD_NAME=$(yq '.planka.board' project.yaml)
```
If `project.yaml` doesn't exist or has no `planka` section, ask the user for the project and board name, then offer to create the file.
### 2. Find or create the project
```bash
PROJECT_ID=$(pcli project list | jq -r --arg name "$PROJECT_NAME" '.data[] | select(.name == $name) | .id')
```
If no project found:
```bash
PROJECT_ID=$(pcli project create --name "$PROJECT_NAME" --type "public" | jq -r '.data.id')
```
### 3. Find or create the board
```bash
# Get project details to find boards
BOARD_ID=$(pcli board list --project "$PROJECT_NAME" | jq -r --arg name "$BOARD_NAME" '.data[] | select(.name == $name) | .id')
```
If no board found:
```bash
BOARD_ID=$(pcli board create --project $PROJECT_ID --name "$BOARD_NAME" | jq -r '.data.id')
```
### 4. Find or create the lists
After obtaining the board, get its current lists:
```bash
EXISTING_LISTS=$(pcli board get $BOARD_ID | jq -r '.data.lists[]? | .name')
```
Create any missing lists with explicit positions to maintain correct ordering:
```bash
# Only create lists that don't already exist
pcli list create --board $BOARD_ID --name "Backlog" --position 65536
pcli list create --board $BOARD_ID --name "To Do" --position 131072
pcli list create --board $BOARD_ID --name "Planning" --position 196608
pcli list create --board $BOARD_ID --name "In Progress" --position 262144
pcli list create --board $BOARD_ID --name "Review" --position 327680
pcli list create --board $BOARD_ID --name "Done" --position 393216
```
Skip any list that already exists (match by name).
### 5. Find or create the `agent` label
```bash
LABEL_ID=$(pcli board get $BOARD_ID | jq -r '.data.labels[]? | select(.name == "agent") | .id')
```
If no `agent` label found:
```bash
LABEL_ID=$(pcli label create --board $BOARD_ID --name "agent" --color "berry-red" | jq -r '.data.id')
```
---
## Reconciliation Steps
### 1. Gather OpenSpec state
```bash
openspec list --json
```
This returns all active changes with their names, schemas, and status.
For each active change:
```bash
openspec status --change "<name>" --json
```
Parse to get:
- Change name
- Schema name
- Artifact completion status (how many artifacts complete vs total)
- Whether all `applyRequires` artifacts are done
- Whether tasks exist and their completion state
If a `tasks.md` exists, read it and parse checkbox state (`- [ ]` vs `- [x]`).
### 2. Determine target list for each change
Map each change to the correct board list based on its OpenSpec state:
| Condition | Target List |
|-----------|-------------|
| Artifacts incomplete (not all `applyRequires` done) | **Planning** |
| Artifacts complete, tasks exist with incomplete items | **In Progress** |
| All tasks complete (all `[x]`) | **Review** |
| Change archived (not in active list) | **Done** |
### 3. Gather Planka state
```bash
pcli card list --board $BOARD_ID | jq '.data[] | select(.labels[]?.name == "agent")'
```
Build a map of existing agent-labelled cards by name, including which list they're currently in.
### 4. Reconcile: create missing cards
For each active OpenSpec change that has no matching Planka card:
```bash
# Determine the correct list based on change state (see step 2)
LIST_ID=$(pcli board get $BOARD_ID | jq -r --arg list "<target-list>" '.data.lists[] | select(.name == $list) | .id')
CARD_ID=$(pcli card create --list $LIST_ID --name "<change-name>" --description "<schema: schema-name>" | jq -r '.data.id')
# Add agent label
pcli card add-label $CARD_ID --label $LABEL_ID
```
### 5. Reconcile: move cards to correct list
For each agent-labelled card that exists but is in the wrong list (based on current OpenSpec state):
```bash
TARGET_LIST_ID=$(pcli board get $BOARD_ID | jq -r --arg list "<target-list>" '.data.lists[] | select(.name == $list) | .id')
pcli card move $CARD_ID --list $TARGET_LIST_ID
```
This ensures cards move through the board as work progresses:
- `Planning` -> `In Progress` when artifacts are complete and apply begins
- `In Progress` -> `Review` when all tasks are marked done
- `Review` -> `Done` when the change is archived
### 6. Reconcile: sync task lists
For each OpenSpec change that has a `tasks.md`:
First, check if the card already has task lists by using `pcli card get`:
```bash
# Get card details including existing task lists and tasks
CARD_DATA=$(pcli card get $CARD_ID)
EXISTING_TL=$(echo "$CARD_DATA" | jq -r '.data.taskLists[0].id // empty')
```
- If `EXISTING_TL` is empty (no task list exists) -> create one and add all tasks
- If `EXISTING_TL` is set (task list already exists) -> compare existing tasks by name and update completion state as needed; only create tasks that don't already exist
```bash
# Create task list ONLY if none exists
if [ -z "$EXISTING_TL" ]; then
TL_ID=$(pcli task-list create --card $CARD_ID --name "Implementation" --show-on-front | jq -r '.data.id')
else
TL_ID="$EXISTING_TL"
fi
# Get existing task names to avoid duplicates
EXISTING_TASKS=$(echo "$CARD_DATA" | jq -r '.data.tasks[] | select(.taskListId == "'$TL_ID'") | .name')
# For each task in tasks.md (in order), assign incrementing positions:
# position = (index + 1) * 65536 (i.e. 65536, 131072, 196608, ...)
# - If a task with the same name already exists, update its completion state if needed
# - If no matching task exists, create it with explicit position
pcli task create --task-list $TL_ID --name "<task description>" --position <pos>
# For tasks already in Planka, update completion state to match tasks.md:
pcli task update <task-id> --completed # if tasks.md shows [x]
```
### 7. Reconcile: move completed/archived changes
For each agent-labelled Planka card that has no matching active OpenSpec change:
- The change was likely archived -> move the card to "Done"
```bash
DONE_LIST_ID=$(pcli board get $BOARD_ID | jq -r '.data.lists[] | select(.name == "Done") | .id')
pcli card move $CARD_ID --list $DONE_LIST_ID
```
### 8. Report
After reconciliation, briefly summarise what changed:
- Infrastructure created (project/board/lists/label): yes/no
- Cards created: N
- Cards moved: N (list details)
- Tasks synced: N
- Cards moved to Done: N
- Errors (if any): list them
---
## Non-Agentic Work
Cards **without** the `agent` label are human-managed and fully read-write. The kanban skill (`/kanban`) handles these directly - creating cards, moving them, adding checklists, etc.
The distinction:
- **Has `agent` label** -> read-only projection, managed by this sync workflow
- **No `agent` label** -> regular Planka card, managed directly by humans
---
## ID Discovery
Planka IDs cannot be cached across sessions. Each sync run must discover IDs dynamically:
1. Read project and board name from `project.yaml`
2. Find the project by name: `pcli project list | jq ...`
3. Find the board by name within the project
4. Find lists on the board: `pcli board get <board-id> | jq ...`
5. Find agent cards: `pcli card list --board <board-id> | jq '.data[] | select(.labels[]?.name == "agent")'`
6. Match cards to changes by name
---
The script handles its own concurrency:
- Uses `flock` to ensure only one sync runs per project-board pair
- If a sync is already running, sets a pending flag and exits immediately
- The running sync re-runs after completion if the pending flag is set
- Multiple pending requests coalesce into a single re-run
## Guardrails
- **Never modify an `agent`-labelled card outside of this sync workflow**
- **Never read Planka to determine what work to do** - query OpenSpec instead
- **Always discover IDs dynamically** - never hardcode or cache across sessions
- **Sync failures are silent** - log a warning but never block opsx workflows
- **One board per project** - if multiple boards exist, ask the user which to sync to
- **Idempotent** - safe to run multiple times, will not create duplicates
- **Bootstrap is safe** - creating project/board/lists is idempotent; existing resources are reused
- Sync is **best-effort** — if Planka is unreachable or the script fails, log a warning and continue
- Never block agentic work because of sync
- If `kanban-project-sync` is not on PATH, log a warning and skip
