About ln-221-story-creator

A standalone-capable skill for planning and creating Stories from an Epic, using a template and configured task tracker. It validates INVEST and acceptance-criteria limits, then returns a structured summary.

Key features

  1. 01Resolve Epic context and load templates
  2. 02Generate and validate Stories
  3. 03Check INVEST and acceptance criteria limits
  4. 04Create Stories and update kanban
  5. 05Return structured summary output

Use cases

  1. 01Planning Stories for an Epic
  2. 02Validating Story content before tracker creation
  3. 03Adding planned Stories to the configured tracker

Install

Copy the command and run it in a terminal.

Story Creator

Type: L3 Worker Category: 2XX Planning

Standalone-first worker for Story creation. It may be called directly or as part of a coordinator flow, but its public contract is the same in both cases.

MANDATORY READ

Load these before execution:

  • references/planning_worker_runtime_contract.md
  • references/coordinator_summary_contract.md
  • references/environment_state_contract.md
  • references/storage_mode_detection.md
  • references/creation_quality_checklist.md
  • references/template_loading_pattern.md

Inputs

Core inputs:

  • epicData
  • idealPlan or appendMode + newStoryDescription
  • standardsResearch
  • teamId
  • autoApprove

Optional transport inputs:

  • runId
  • summaryArtifactPath

The worker must remain fully usable without caller-provided runId and without summaryArtifactPath. In standalone mode it generates its own run_id before emitting the summary envelope.

Runtime

Runtime family: planning-worker-runtime

Identifier:

  • epic-{epicId}

Phases:

  1. PHASE_0_CONFIG
  2. PHASE_1_RESOLVE_CONTEXT
  3. PHASE_2_LOAD_TEMPLATE
  4. PHASE_3_GENERATE_STORIES
  5. PHASE_4_VALIDATE_STORIES
  6. PHASE_5_CONFIRM_OR_AUTOAPPROVE
  7. PHASE_6_APPLY_CREATE
  8. PHASE_7_UPDATE_KANBAN
  9. PHASE_8_WRITE_SUMMARY
  10. PHASE_9_SELF_CHECK

Managed child-run mode:

  • caller starts the runtime with --run-id and --summary-artifact-path
  • runtime writes the final summary artifact directly to the caller-provided path
  • parent coordinator records the resulting story-plan-worker artifact

Standalone mode:

  • runtime generates its own run_id
  • runtime still returns the same structured summary envelope
  • artifact writing is optional unless summaryArtifactPath is provided

Output Contract

Always build a structured summary envelope:

  • schema_version
  • summary_kind=story-plan-worker
  • run_id
  • identifier
  • producer_skill=ln-221
  • produced_at
  • payload

Payload fields:

  • mode
  • epic_id
  • stories_planned
  • stories_created
  • stories_updated
  • stories_canceled
  • story_urls
  • warnings
  • kanban_updated
  • research_path_used

If summaryArtifactPath is provided:

  • write the same JSON summary to that path

If summaryArtifactPath is not provided:

  • return the same summary in structured output only

Managed artifact path pattern:

  • .hex-skills/runtime-artifacts/runs/{parent_run_id}/story-plan-worker/ln-221--{identifier}.json

Workflow

  1. Resolve task provider and Epic context if not already provided.
  2. Load the Story template.
  3. Generate Story documents with exactly the template sections.
  4. Insert standards research into Technical Notes only.
  5. Validate INVEST and AC limits before creation.
  6. Show preview unless autoApprove=true.
  7. Create Stories via the configured tracker provider.
  8. Update kanban.
  9. Write story-plan-worker summary.
  10. Return structured summary.

Critical Rules

  • Keep exactly the template-defined Story structure.
  • Insert standards research into Technical Notes, not into ACs.
  • Reject Stories that fail INVEST or exceed AC limits.
  • STOP before tracker createStory: verify all 9 sections present in body: Story, Context, Acceptance Criteria, Implementation Tasks, Test Strategy, Technical Notes, Definition of Done, Dependencies, Assumptions. PreToolUse hook will BLOCK creation without them.
  • Remain standalone-capable.
  • Never require coordinator runtime state to operate.

Definition of Done

  • Story template loaded and respected
  • Story documents generated
  • INVEST validation passed
  • Stories created in provider-specific storage
  • kanban updated
  • Structured summary returned
  • Summary artifact written when summaryArtifactPath is provided
