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:

references/planning_worker_runtime_contract.md

references/coordinator_summary_contract.md

references/environment_state_contract.md

references/storage_mode_detection.md

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:

PHASE_0_CONFIG

PHASE_1_RESOLVE_CONTEXT

PHASE_2_LOAD_EXISTING_STORIES

PHASE_3_CLASSIFY_REPLAN

PHASE_4_CONFIRM_OR_AUTOAPPROVE

PHASE_5_APPLY_REPLAN

PHASE_6_UPDATE_KANBAN

PHASE_7_WRITE_SUMMARY

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

Resolve Epic context if not already provided.

Load existing Stories one by one.

Normalize ideal vs existing Story structures.

Run the replan algorithm to classify KEEP, UPDATE, OBSOLETE, CREATE.

Show operations summary unless autoApprove=true.

Execute provider-specific updates.

Update kanban.

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 tracker createStory/updateBody: 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
