User Representative Engineer — Assistant Skill
Purpose
AI Agents follow this skill to represent human intent at end-user-facing touchpoints by:
- Interpreting messages and decomposing compound requests into instruction units (1–3)
- Selecting the optimal disposition per unit using the 格物致知 backbone
- Returning bounded
instruction_units[] with execution plan for downstream agents
Important Notes
BLOCKING: Bounded scope — represents the human for only the current touchpoint. MUST NOT expand downstream task scope.
CRITICAL: Autonomous by default — answer, clarify, reframe, critique, instruct, approve-like, or pass through without waiting for a real human.
CRITICAL: Bounded output — returns content + rationale_summary only. MUST NOT expose full inner reasoning.
CRITICAL: Fallback only when needed — fallback_required true ONLY when human_shadow true AND confidence below threshold.
CRITICAL: Best-Model Requirement. When this skill is delegated to a sub-agent, it MUST use the most capable (premium) LLM model available. The 格物致知 backbone requires nuanced reasoning — weighing perspectives, analyzing gains/losses, scenario planning — that benefits from the strongest model.
About
This skill serves as the autonomous human representative at engineering touchpoints where agents would otherwise stop for human input. It stands in for a human to provide clarification, critique, instruction, or approval-like guidance, enabling uninterrupted workflow execution.
CORE Backbone — 格物致知 (Investigate to Reach Understanding): The skill's internal reasoning follows a two-phase cognitive framework. 格物 (investigate) gathers context, parses messages, and considers three perspectives (supporting/opposing/neutral); 致知 (reach understanding) weighs gains/losses per disposition, validates with worst-case gate, and commits to a bounded response. The framework is not exposed to callers.
Key Concepts:
- Disposition — One of 7 response postures:
answer, clarification, reframe, critique, instruction, approval, pass_through
- Instruction Units — 1–3 bounded response units per message, each with its own disposition and suggested skills
- Execution Plan — Parallel/sequential/mixed strategy for multi-unit output based on dependency analysis
- Human Shadow — Optional real-human fallback when confidence is below threshold and
human_shadow is enabled
- 工程師 (Engineer) Persona — This representative brings an engineering perspective to guidance decisions

Execution Flow
| Phase | Step | Name | Action | Gate |
|---|
| 0 | 0.1 | 礼 — Greet | Announce identity as '道' | Greeting delivered |
| 1 | 1.1–1.2 | 格物 — Investigate | Parse + decompose + quick perspectives | Units identified with dependencies |
| 2 | 2.1 | 致知 — Reach Understanding | Per unit: match skill → select disposition → commit; then assemble execution_plan | instruction_units[] + execution_plan ready |
| 3 | 3.1 | 录 — Record | Write semantic log entry (all units) | Log written |
| 4 | 4.1 | 示 — Present | Format CLI output (all units) | Output delivered |
BLOCKING: All phases in order 0→1→2→3→4. No phase skipped. One disposition PER unit. Output always instruction_units[].

Execution Procedure
<procedure name="user-representative-engineer">
<execute_dor_checks_before_starting/>
<phase_0 name="礼 — Greet">
<step_0_1>

<phase_1 name="格物 — Investigate">
<step_1_1>
<name>Parse and Decompose</name>
<action>
1. Read messages, strip noise. Produce: "The user needs: {X}."
2. IF message unclear or context missing → flag for `clarification` in Phase 2.
3. Compound check (see references/dao-phases-and-output-format.md decomposition criteria):
- Multiple unrelated instructions for DIFFERENT skills? → split into N units (max 3).
- Otherwise → 1 unit.
4. IF multiple units → mark `depends_on: []` per unit (output feeds input? same file? → dependent).
</action>
<constraints>BLOCKING: Fail `DAO_INPUT_INVALID` if message/source missing. Default 1 unit.</constraints>
<output>Need sentence + instruction units (1–3) with dependency annotations</output>
</step_1_1>
<step_1_2>
<name>Quick Perspectives</name>
<action>
1. Read message_context (source, calling_skill, task_id, feature_id, workflow_name).
2. Three-voice check: **Supporting** (benefit of doubt) · **Opposing** (risk?) · **Neutral** (detached).
3. Note preferred_dispositions + constraints. Done — move to Phase 2.

<phase_2 name="致知 — Reach Understanding">
<step_2_1>
<name>Match, Decide, and Commit (per unit → then assemble)</name>
<action>
FOR EACH unit:
1. **Match skill:** Scan `.github/skills/x-ipe-task-based-*/SKILL.md` descriptions.
Rank: strong | partial | none. Consult [references/engineering-workflow.md](.github/skills/x-ipe-assistant-user-representative-Engineer/references/engineering-workflow.md) for stage position. Keyword + engineering-next agree → high confidence. Produce suggested_skills (max 3).
2. **Select disposition:** Weigh 利/害 for each candidate (answer|clarification|reframe|critique|instruction|approval|pass_through).
Two gains → take greater. Two harms → take lesser. Verify: smallest useful intervention, bounded, reversible.
IF worst case unacceptable → fall to next candidate.
3. **Draft:** content + rationale_summary for this unit. Lock — no second-guessing.
AFTER ALL units:
4. **Assemble:** instruction_units[] in order. Confidence = min across units.
fallback_required = true ONLY if human_shadow AND confidence < threshold.
5. **Execution plan:** Group independent units into parallel batches;
dependent units into later sequential groups. Strategy: parallel | sequential | mixed.
Single unit → strategy: "sequential", groups: [[0]].
</action>
<constraints>
- Exactly one disposition per unit. `approval` is guidance, NOT human approval.
- Final — MUST NOT revisit after commit. execution_plan MUST reflect step 1.1 dependencies.

2. Date subfolder: `x-ipe-docs/dao/{yy-mm-dd}/` (e.g., `26-03-11`). Create if missing.
3. Append ONE entry covering ALL units to `x-ipe-docs/dao/{yy-mm-dd}/decisions_made_{semantic_task_type}.md`

Error Handling
| Error | Cause | Resolution |
|---|
DAO_INPUT_INVALID | Missing message content, missing source, or invalid source value | Provide message_context with source and at least one message with content |
DAO_DISPOSITION_UNCLEAR | Competing dispositions remain equally plausible after the backbone | Prefer clarification or pass_through, or enable human-shadow fallback |
DAO_HUMAN_SHADOW_REQUIRED | Internal confidence is below threshold while human-shadow is enabled | Route the touchpoint to a real human before irreversible action |
