When to Use This Skill

Use this skill when you need to:

1. Add parent story context (parent-KEY.md) to agent input folders
2. Add sibling BA/SA/VD subtask context (parent_context_ba.md, parent_context_sa.md, parent_context_vd.md)
3. Configure Jira custom fields (Acceptance Criteria, Solution, Diagrams, etc.) for context retrieval
4. Set up a new project with parent context enrichment
5. Debug missing parent context files in agent input

How It Works

The fetchParentContextToInput.js pre-CLI action:

1. Reads the current ticket's parent key from ticket.fields.parent
2. Fetches the parent story with configured fields → writes input/parent-{KEY}.md
3. Runs a JQL search for siblings with [BA], [SA], or [VD] prefix → writes input/parent_context_{ba,sa,vd}.md
4. All fields are rendered as clean markdown with human-readable labels

File Layout in Input Folder

input/
└── TICKET/
    ├── request.md
    ├── comments.md
    ├── parent-TS-100.md           ← parent story (configurable fields)
    ├── parent_context_ba.md       ← Business Analysis sibling
    ├── parent_context_sa.md       ← Solution Architecture sibling
    └── parent_context_vd.md       ← Visual Design sibling

Configuration

1. Project Config (.dmtools/config.js)

Recommended: aggregation from jira.fields

Define your custom fields once in jira.fields. fetchParentContextToInput.js automatically aggregates all human-readable field names into the default field set:

module.exports = {
  jira: {
    project: 'TS',
    parentTicket: 'TS-1',
    fields: {
      acceptanceCriteria: 'Acceptance Criteria',
      solution: 'Solution',
      diagrams: 'Diagrams',
      answer: 'Answer'
      // Skip raw customfield_* IDs here — they are technical, not for context
    },
    parentContextFetch: {
      enabled: true,
      resolveFieldNames: true,   // resolves "Acceptance Criteria" → "customfield_10397"
      // parentFields omitted → auto-aggregated from jira.fields + DEFAULT_FIELDS
      siblingFields: ['key', 'summary', 'description', 'status', 'comment', 'Acceptance Criteria']
    }
  },
  defaultTracker: 'jira'
};

How aggregation works:

• buildDefaultFields() starts with ['key', 'summary', 'description', 'status', 'comment']
• Then appends every human-readable value from jira.fields (skips raw customfield_* IDs)
• Result for the example above: ['key', 'summary', 'description', 'status', 'comment', 'Acceptance Criteria', 'Solution', 'Diagrams', 'Answer']

Explicit override (when you need different fields for parent vs siblings):

parentContextFetch: {
  enabled: true,
  parentFields: ['key', 'summary', 'description', 'status', 'Acceptance Criteria', 'Solution', 'Diagrams'],
  siblingFields: ['key', 'summary', 'description', 'status', 'comment', 'Acceptance Criteria']
}

Find your custom field names:

curl -u "$JIRA_EMAIL:$JIRA_API_TOKEN" \
  "https://YOUR-JIRA.atlassian.net/rest/api/3/issue/KEY?expand=names"

2. Agent JSON Override

For per-agent customization, add customParams.parentContextFetch:

{
  "params": {
    "customParams": {
      "parentContextFetch": {
        "enabled": true,
        "parentFields": ["key", "summary", "description", "status", "Acceptance Criteria"],
        "siblingFields": ["key", "summary", "description", "status", "comment"]
      }
    }
  }
}

3. Agent Prompts

Ensure the agent reads parent context files. Add input_context_reading.md to cliPrompts:

{
  "cliPrompts": [
    "./agents/instructions/common/input_context_reading.md"
  ]
}

The input_context_reading.md mermaid diagram instructs the agent to read:

• input/TICKET/parent-KEY.md — parent story summary, description, ACs
• input/TICKET/parent_context_ba.md / sa.md / vd.md — BA/SA/VD context

Agent Setup

Enable for an Agent

Add preCliJSAction to the agent JSON:

{
  "params": {
    "preCliJSAction": "agents/js/fetchParentContextToInput.js"
  }
}

Agents that should use it:

• solution_description.json — needs parent ACs and Solution field
• po_refinement.json — needs parent context for product decisions
• story_questions.json — via fetchQuestionsToInput.js (auto-chained)
• story_development.json — via preCliDevelopmentSetup.js (auto-chained)
• bug_development.json — via preCliDevelopmentSetup.js (auto-chained)
• pr_review.json — via preparePRForReview.js (auto-chained)
• pr_rework.json — via preCliReworkSetup.js (auto-chained)

Composite Script Chaining

If the agent already has a composite pre-CLI script, chain fetchParentContextToInput.js at the end:

// In preCliDevelopmentSetup.js or similar
var fetchParentContext = require('../fetchParentContextToInput.js');
fetchParentContext.action(params);

Integration Test

Run the dmtools jsrunner integration test against a real ticket:

cd agents

# Subtask with parent story
dmtools run js/integration-tests/run_fetchParentContext_test.json

# Story with parent epic
dmtools run js/integration-tests/run_fetchParentContext_TS575.json

# Subtask with [SA] sibling
dmtools run js/integration-tests/run_fetchParentContext_JD9.json

# Story with filled custom fields (Acceptance Criteria, Solution, Diagrams)
dmtools run js/integration-tests/run_fetchParentContext_TS728.json

Check outputs/input/parent-*.md for generated content.

Troubleshooting

Debug with Real API

# Check what dmtools returns for a ticket
cat > /tmp/debug.json << 'EOF'
{
  "name": "JSRunner",
  "params": {
    "jsPath": "js/unit-tests/debug.js"
  }
}
EOF

cat > agents/js/unit-tests/debug.js << 'EOF'
function action() {
  var ticket = jira_get_ticket({ key: 'TS-637', fields: ['summary', 'customfield_10397'] });
  console.log('Keys: ' + Object.keys(ticket.fields).join(', '));
  return {};
}
EOF

dmtools run /tmp/debug.json
