| name | x-ipe-task-based-change-request |
| description | Process change requests by analyzing impact on existing requirements and features, detecting conflicts with specs/designs/code. Determines if CR modifies existing feature (-> refinement) or requires new feature (-> requirement update + feature breakdown). Triggers on "change request", "CR", "modify feature", "update requirement". |
Task-Based Skill: Change Request
Purpose
Process change requests (CRs) systematically by:
- Analyzing the change request against existing requirements and features
- Classifying the CR as modification to existing feature or new feature
- Detecting conflicts with existing specifications, technical designs, and dependencies
- Routing to appropriate workflow (Feature Refinement or Requirement Update + Feature Breakdown)
- Maintaining traceability and documentation
Important Notes
BLOCKING: Learn x-ipe-workflow-task-execution skill before executing this skill.
Note: If Agent does not have skill capability, go to .github/skills/ folder to learn skills. SKILL.md is the entry point.
IMPORTANT: When process_preference.interaction_mode == "dao-represent-human-to-interact", NEVER stop to ask the human. Instead, call x-ipe-assistant-user-representative-Engineer to get the answer. The DAO skill acts as the human representative and will provide the guidance needed to continue.

Execution Flow
| Phase | Steps | Action | Gate |
|---|
| 1. 博学之 — Study Broadly | 1.1 Understand Change Request, 1.2 CR Context Study | Parse CR context, research similar features and standards | CR context established |
| 2. 审问之 — Inquire Thoroughly | 2.1 CR Challenge, 2.2 Analyze Impact | Challenge CR assumptions, review existing requirements and features | Impact analyzed |
| 3. 慎思之 — Think Carefully | 3.1 Detect Conflicts | Analyze spec/design/dependency conflicts with existing features | Conflicts classified |
| 4. 明辨之 — Discern Clearly | 4.1 Classify CR Type, 4.2 Route Workflow | Classify modification vs new feature, confirm classification | Classification confirmed |
| 5. 笃行之 — Practice Earnestly | 5.1 Execute & Document | Resolve conflicts, confirm large-scope changes with human, update spec + docs (both paths), create CR record | CR documented |
| 继续执行 | 6.1 | Decide Next Action | DAO-assisted next task decision |
| 继续执行 | 6.2 | Execute Next Action | Load skill, generate plan, execute |
BLOCKING: Phase 3 must complete before Phase 4 — do NOT classify without conflict analysis.
BLOCKING: Classification MUST be confirmed before Phase 5 execution (manual/stop_for_question: human confirms; auto: DAO confirms via x-ipe-assistant-user-representative-Engineer).
BLOCKING: Specification MUST be updated for BOTH modification and new_feature classifications.
BLOCKING: Large-scope CRs require human confirmation of the proposed feature change solution BEFORE Phase 5 document changes are applied.

<step_2_1>
<name>CR Challenge</name>
<action>
1. Challenge CR assumptions:
- Is this change truly necessary? What problem does it solve?
- Could the existing feature already handle this with configuration?
- Is the requested approach the best solution, or are there alternatives?
- What is the impact if this CR is NOT implemented?
2. Present challenges and ask for confirmation
3. Document challenge outcomes and confirmed scope
Response source (based on interaction_mode):

0. Resolve extra_context_reference inputs (closing-report, specification)
1. READ requirement-details.md: understand project scope, identify related requirements
2. READ features.md: list all features, note statuses, identify related features
3. FOR EACH related feature: read specification if exists (ACs, user stories, out-of-scope)

b. Check specification Linked Mockups section for status

<phase_3 name="慎思之 — Think Carefully">
<step_3_1>
<name>Detect Conflicts</name>
<action>
1. Spawn sub-agent (Conflict Detector) to analyze CR against existing artifacts:
- Read specs and technical designs of related features
- Read implemented code for affected features
- Identify spec conflicts, design conflicts, dependency conflicts, pending CR conflicts
2. IF no conflicts: proceed to Phase 4
3. IF conflicts: classify each as "expected" or "unexpected"
4. IF any "unexpected": document with explanation, suggest mitigations

<name>Execute & Document</name>
<action>
0. Resolve conflicting documents (from Phase 3 conflict analysis):
- Applies regardless of resolution method (human confirmation or interaction_mode)
- FOR EACH conflict with an existing document (spec, design, requirement):
a. IF minor conflict (wording update, small AC adjustment, additive change):
→ Directly update the target document inline with CR changes
b. IF major conflict (structural redesign, contradicting requirements, scope change):
→ Mark affected sections in target document with "[RETIRED by CR-XXX]" header
→ Add retirement note: reason, date, and reference to CR-XXX.md
→ Write replacement content in the appropriate location (new section or updated section)
0b. Large-scope confirmation gate:
- IF CR impacts a large scope of change (multiple features, structural redesign,
significant AC rewrites, or new workflows):
→ Present the proposed feature change solution (spec changes, affected ACs,
conflict resolutions) to human for confirmation BEFORE executing changes
→ Wait for human approval or revision
Response source (based on interaction_mode):
IF process_preference.interaction_mode == "dao-represent-human-to-interact":
→ Confirm via x-ipe-assistant-user-representative-Engineer
ELSE:
→ Ask human directly
- IF CR is small-scope (single feature, minor AC additions/edits):
→ Proceed without additional confirmation (Phase 4.2 already confirmed classification)
1. IF classification = "modification":
a. CREATE CR-XXX.md using templates/change-request.md
b. UPDATE specification.md: Version History + affected sections/ACs
c. IF CR affects high-level requirements: update requirement-details.md
d. IF UI/UX CR with existing mockups: create new mockup version (never override)
e. SET next_task_based_skill = x-ipe-task-based-feature-refinement

a. UPDATE requirement-details.md: add new requirement
b. UPDATE specification.md: Version History + new sections/ACs for the CR changes
c. SET next_task_based_skill = x-ipe-task-based-feature-breakdown
d. NOTE: CR-XXX.md created after feature breakdown creates folder
3. Create CR record at FEATURE-XXX/CR-XXX.md

Classification Criteria
Decision Tree: No related feature → new_feature | Related feature + fundamental scope change → new_feature | Related feature + within boundaries → modification
| Classification | Indicators |
|---|
new_feature (scope change) | New workflows, data models, user types/roles, integration points, purpose change |
modification | Within boundaries, extends user stories, no new endpoints/screens, same users |
new_feature (boundary) | Expands boundaries, new user stories, new UI/API/data models, separate docs |
Update requirement-details.md (modification path) when: CR adds high-level capability, changes constraints, affects multiple features, changes user types, or modifies project-level business rules.

Patterns & Anti-Patterns
| Pattern | When | Then |
|---|
| Classification Decision | Classification unclear | Score against criteria, if score diff ≤2 ask human (manual/stop_for_question) or DAO (auto) |
| Conflict Resolution | Unexpected conflicts found | Present with impact, suggest mitigations, split CR if severe |
| Enhancement CR | See [references/patterns.md] | Match existing feature, classify modification |
| Multi-Feature CR | CR touches many features | One CR = one classification; split if needed |
| Anti-Pattern | Why Bad | Do Instead |
|---|
| Skip classification | Wrong workflow chosen | Always classify explicitly |
| Classify before conflicts | May miss scope issues | Phase 3 (conflicts) before Phase 4 (classify) |
| No classification confirmation | Risk wrong direction | Always confirm classification at Phase 4.2 (human in manual/stop_for_question; DAO in auto) |
| Skip conflict analysis | Break existing features | Always detect conflicts in Phase 3 |
| Override existing mockup | Lost design history | Create new version (v{N+1}), keep original |
| Leave conflicting docs unresolved | Stale docs mislead future work | Minor → update inline; major → mark retired |
| No version history | Lost change history | Update specification version |
Examples
See references/examples.md for concrete execution examples:
- Bulk import CR classification (NEW_FEATURE)
- UI enhancement CR classification (MODIFICATION)
- CR with dependency conflict (MODIFICATION with conflict analysis)
- Ambiguous request requiring clarification
- Bug report redirection (NOT_A_CR)
