Story Replanner

Type: L3 Worker Category: 2XX Planning

Standalone-first worker for Story replanning. It compares ideal Story intent with existing Stories and applies the resulting operations.

MANDATORY READ

Load these before execution:

• shared/references/planning_worker_runtime_contract.md
• shared/references/coordinator_summary_contract.md
• shared/references/environment_state_contract.md
• shared/references/storage_mode_detection.md
• shared/references/template_loading_pattern.md
• references/replan_algorithm_stories.md

Inputs

Core inputs:

• epicData
• idealPlan
• existingStoryIds
• 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_EXISTING_STORIES
4. PHASE_3_CLASSIFY_REPLAN
5. PHASE_4_CONFIRM_OR_AUTOAPPROVE
6. PHASE_5_APPLY_REPLAN
7. PHASE_6_UPDATE_KANBAN
8. PHASE_7_WRITE_SUMMARY
9. PHASE_8_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-222
• 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-222--{identifier}.json

Workflow

1. Resolve Epic context if not already provided.
2. Load existing Stories one by one.
3. Normalize ideal vs existing Story structures.
4. Run the replan algorithm to classify KEEP, UPDATE, OBSOLETE, CREATE.
5. Show operations summary unless autoApprove=true.
6. Execute provider-specific updates.
7. Update kanban.
8. Return structured summary.

Critical Rules

• Prefer conservative updates when matching is ambiguous.
• Preserve finished work when replanning conflicts with completed Stories.
• Keep the worker standalone-capable.
• Never require coordinator runtime state to operate.
• Return machine-readable results, not prose-only outcomes.
• STOP before save_issue: 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.

Definition of Done

• [ ] Existing Stories loaded and normalized
• [ ] Replan algorithm applied
• [ ] Required updates, cancellations, and creations executed
• [ ] kanban updated
• [ ] Structured summary returned
• [ ] Summary artifact written when summaryArtifactPath is provided
