Project Board Enforcement

Overview

The GitHub Project board is THE source of truth for all work state. Not labels. Not comments. Not memory. The project board.

Core principle: If it's not in the project board with correct fields, it doesn't exist.

This skill is called by other skills at gate points. It is not invoked directly.

API Optimization Requirement

CRITICAL: All read operations MUST use cached data from github-api-cache.

The following environment variables MUST be set before using this skill:

• GH_CACHE_ITEMS - Cached project items JSON
• GH_CACHE_FIELDS - Cached project fields JSON
• GH_PROJECT_ID - Project node ID
• GH_STATUS_FIELD_ID - Status field ID
• GH_STATUS_*_ID - Status option IDs

If these are not set, invoke session-start first to initialize the cache.

The Rule

Every issue, epic, and initiative MUST be in the project board BEFORE work begins.

This is not optional. This is not a suggestion. This is a hard gate.

Required Environment

# These MUST be set. Work cannot proceed without them.
echo $GITHUB_PROJECT      # Full URL: https://github.com/users/USER/projects/N
echo $GITHUB_PROJECT_NUM  # Just the number: N
echo $GH_PROJECT_OWNER    # Owner: @me or org name

If any are missing, stop and configure them before proceeding.

Project Field Requirements

Mandatory Fields

Every project MUST have these fields configured:

Recommended Fields

Verification Functions

All read operations use cached data (0 API calls). Only writes require API calls.

Verify Issue in Project

GATE FUNCTION - Called before any work begins. 0 API calls (uses cache).

verify_issue_in_project() {
  local issue=$1

  # Get project item ID FROM CACHE (0 API calls)
  ITEM_ID=$(echo "$GH_CACHE_ITEMS" | jq -r ".items[] | select(.content.number == $issue) | .id")

  if [ -z "$ITEM_ID" ] || [ "$ITEM_ID" = "null" ]; then
    echo "BLOCKED: Issue #$issue is not in the project board."
    echo ""
    echo "Add it with:"
    echo "  gh project item-add $GITHUB_PROJECT_NUM --owner $GH_PROJECT_OWNER --url \$(gh issue view $issue --json url -q .url)"
    return 1
  fi

  echo "$ITEM_ID"
  return 0
}

Verify Status Field Set

GATE FUNCTION - Called before work proceeds past issue check. 0 API calls (uses cache).

verify_status_set() {
  local issue=$1
  local item_id=$2

  # Get current status FROM CACHE (0 API calls)
  STATUS=$(echo "$GH_CACHE_ITEMS" | jq -r ".items[] | select(.id == \"$item_id\") | .status.name")

  if [ -z "$STATUS" ] || [ "$STATUS" = "null" ]; then
    echo "BLOCKED: Issue #$issue has no Status set in project board."
    echo ""
    echo "Set status before proceeding."
    return 1
  fi

  echo "$STATUS"
  return 0
}

Add Issue to Project

Called by issue-prerequisite after issue creation. 1 API call + cache refresh.

add_issue_to_project() {
  local issue_url=$1

  # Add to project (1 API call - unavoidable write)
  gh project item-add "$GITHUB_PROJECT_NUM" --owner "$GH_PROJECT_OWNER" --url "$issue_url"

  if [ $? -ne 0 ]; then
    echo "ERROR: Failed to add issue to project."
    return 1
  fi

  # Refresh cache after adding (1 API call)
  export GH_CACHE_ITEMS=$(gh project item-list "$GITHUB_PROJECT_NUM" --owner "$GH_PROJECT_OWNER" --format json)

  # Get the item ID from refreshed cache
  local issue_num=$(echo "$issue_url" | grep -oE '[0-9]+$')
  ITEM_ID=$(echo "$GH_CACHE_ITEMS" | jq -r ".items[] | select(.content.number == $issue_num) | .id")

  echo "$ITEM_ID"
  return 0
}

Set Project Status

Called at every status transition. 1 API call (uses cached IDs).

set_project_status() {
  local item_id=$1
  local new_status=$2  # Backlog, Ready, In Progress, In Review, Done, Blocked

  # Use cached IDs (0 API calls for lookups)
  # GH_PROJECT_ID, GH_STATUS_FIELD_ID set by session-start

  # Get option ID from cache
  local option_id
  case "$new_status" in
    "Backlog")     option_id="$GH_STATUS_BACKLOG_ID" ;;
    "Ready")       option_id="$GH_STATUS_READY_ID" ;;
    "In Progress") option_id="$GH_STATUS_IN_PROGRESS_ID" ;;
    "In Review")   option_id="$GH_STATUS_IN_REVIEW_ID" ;;
    "Done")        option_id="$GH_STATUS_DONE_ID" ;;
    "Blocked")     option_id="$GH_STATUS_BLOCKED_ID" ;;
    *)
      # Fallback: look up from cached fields (0 API calls)
      option_id=$(echo "$GH_CACHE_FIELDS" | jq -r ".fields[] | select(.name == \"Status\") | .options[] | select(.name == \"$new_status\") | .id")
      ;;
  esac

  if [ -z "$option_id" ] || [ "$option_id" = "null" ]; then
    echo "ERROR: Status '$new_status' not found in project."
    return 1
  fi

  # Single API call to update status
  gh project item-edit --project-id "$GH_PROJECT_ID" --id "$item_id" \
    --field-id "$GH_STATUS_FIELD_ID" --single-select-option-id "$option_id"

  return $?
}

Set Project Type

Called when creating issues. 1 API call (uses cached IDs).

set_project_type() {
  local item_id=$1
  local type=$2  # Feature, Bug, Chore, Research, Spike, Epic, Initiative

  # Get type field ID and option from cache (0 API calls)
  local type_field_id=$(echo "$GH_CACHE_FIELDS" | jq -r '.fields[] | select(.name == "Type") | .id')
  local option_id=$(echo "$GH_CACHE_FIELDS" | jq -r ".fields[] | select(.name == \"Type\") | .options[] | select(.name == \"$type\") | .id")

  if [ -z "$option_id" ] || [ "$option_id" = "null" ]; then
    echo "ERROR: Type '$type' not found in project."
    return 1
  fi

  # Single API call to update type
  gh project item-edit --project-id "$GH_PROJECT_ID" --id "$item_id" \
    --field-id "$type_field_id" --single-select-option-id "$option_id"
}

State Queries via Project Board

All queries use cached data. 0 API calls.

Get Issues by Status

USE THIS instead of label queries. 0 API calls (uses cache).

get_issues_by_status() {
  local status=$1  # Ready, In Progress, etc.

  # Use cached data (0 API calls)
  echo "$GH_CACHE_ITEMS" | jq -r ".items[] | select(.status.name == \"$status\") | .content.number"
}

# Examples:
# get_issues_by_status "Ready"
# get_issues_by_status "In Progress"
# get_issues_by_status "Blocked"

Get Issues by Type

0 API calls (uses cache).

get_issues_by_type() {
  local type=$1  # Epic, Feature, etc.

  echo "$GH_CACHE_ITEMS" | jq -r ".items[] | select(.type.name == \"$type\") | .content.number"
}

Get Epic Children

0 API calls (uses cache).

get_epic_children() {
  local epic_num=$1

  echo "$GH_CACHE_ITEMS" | jq -r ".items[] | select(.epic == \"#$epic_num\") | .content.number"
}

Count by Status

0 API calls (uses cache).

count_by_status() {
  local status=$1

  echo "$GH_CACHE_ITEMS" | jq "[.items[] | select(.status.name == \"$status\")] | length"
}

Gate Points

These are the points in workflows where project board verification is MANDATORY:

Transition Rules

Valid transitions:

Backlog → Ready → In Progress → In Review → Done
   ↓        ↓          ↓            ↓
   └────────┴──────────┴────────────┴──→ Blocked
                                            ↓
                                    (return to previous)

Transition Enforcement

validate_transition() {
  local current=$1
  local target=$2

  case "$current→$target" in
    "Backlog→Ready"|"Ready→In Progress"|"In Progress→In Review"|"In Review→Done")
      return 0 ;;
    *"→Blocked")
      return 0 ;;
    "Blocked→Backlog"|"Blocked→Ready"|"Blocked→In Progress")
      return 0 ;;
    *)
      echo "INVALID_TRANSITION: $current → $target"
      return 1 ;;
  esac
}

Labels vs Project Board

WRONG: Using labels for state (status:in-progress) RIGHT: Using project board Status field

Labels are only for supplementary info: epic, epic-[name], spawned-from:#N, review-finding

Sync Verification

Detect drift by comparing git branches to project board status:

• Issues with branches should be In Progress or In Review
• In Progress issues should have active branches

Use cached data (GH_CACHE_ITEMS) for 0 API calls. Example:

# Check if branch status matches project board
status=$(echo "$GH_CACHE_ITEMS" | jq -r ".items[] | select(.content.number == $issue) | .status.name")

Error Messages

All project board errors provide actionable fixes:

Integration

This skill is called by:

• issue-driven-development - All status transitions
• issue-prerequisite - After issue creation
• epic-management - Epic and child issue setup
• autonomous-orchestration - State queries and updates
• session-start - Sync verification
• work-intake - Project readiness check

This skill requires cache from:

• github-api-cache - Provides GH_CACHE_ITEMS, GH_CACHE_FIELDS, and field IDs

Checklist for Callers

Before proceeding past any gate:

• GitHub API cache initialized (GH_CACHE_ITEMS, GH_CACHE_FIELDS set)
• Issue exists in project (verified from cache, not API call)
• Status field is set
• Type field is set
• Priority field is set (for new issues)
• Epic linkage set (if child of epic)
• Transition is valid (if changing status)
