description	Structured code audit workflow supporting both PRD-based and prompt-based evaluation modes. evaluatorX is a pure analyzer -reads dispatch-selected docs + code, outputs structured Evaluation Result Payload. Document writes are handled by Main Agent, not evaluatorX.

Evaluator: Code Audit Skill (PRD-Based & Prompt-Based)

Why This Skill Is Needed

In iterative development, an independent audit step is needed after the coding agent completes implementation:

• Whether code aligns with PRD requirements or original prompt intent
• Whether code quality meets standards
• Optimization direction for the next iteration

evaluatorX is a pure analyzer: reads Review Dispatch-selected documents and code, outputs structured Evaluation Result Payload. Does not write to any document. Document updates are handled by Main Agent.

Trigger Conditions

Loaded when the user or upstream agent requests "audit code", "evaluate implementation", "run evaluator", "review". Main Agent also invokes this in prompt-based mode.

Core Workflow

Step 1: Read Review Dispatch Payload

1. Read the Dispatch Payload: evaluatorX Review Task handed off by Main Agent.
2. If the Review Dispatch Payload is missing, internally inconsistent, or lacks required fields, stop and return Evaluation Contract Missing with the missing fields. Do not infer evaluation scope from conversation history.
3. Extract:
   • Evaluation Type: full | partial | fix | final | prompt-based
   • Review Brief
   • Parent Path / Child Path
   • Acceptance Source / Original Prompt
   • Changed Files
   • Affected ACs Claimed
   • Review Focus
   • Review Context Manifest / Review Context Budget
   • Required Reads / Conditional Reads / Expansion Rules
   • MCP Policy
4. If no hybrid document is provided, switch to Prompt-Based mode only when the dispatch explicitly says so.

The Review Brief is authoritative. evaluatorX audits the declared target, acceptance scope, risk focus, non-goals, and pass criteria. Do not re-discover the feature or review objective from conversation history.

Step 1A: Required Reads, In Order

Read only the Review Context Manifest -> Read First / Required Reads materials first:

1. Change Summary Payload
2. git diff for Changed Files
3. changed file hunks and immediate surrounding code needed to understand the diff
4. Acceptance Source content: Child Section 7 acceptance criteria scoped by Evaluation Type, or Original Prompt for prompt-based mode
5. Child Section 9 only when Prior Evaluation Source is not N/A

This ordering is intentional: evaluatorX should understand the actual code change before expanding document context.

Step 1B: Conditional Reads

Read additional context only when Review Context Manifest -> Read If Needed, the dispatch, or the diff creates a named risk:

• Parent Sections 0-6: only when global scope, NFR, DoD, or project constraints may be affected.
• Parent Section 8.1: only to map changed files to known ownership/index.
• Parent Section 8.3: only when dependency or cross-branch ownership is relevant.
• Parent Section 8.2 / MCP: only when exact node names are needed for a named review risk and MCP Policy permits it.
• Additional source files: only when changed code references their functions, types, API contracts, or shared state.

Every conditional read must be listed in the Context Expansion section of the Evaluation Result Payload with path/node, reason, and result.

Use Review Context Budget to cap broad searches, document reads, source-file reads, and MCP retrieval. If the audit must exceed the budget, record the exact expansion and reason in Context Expansion.

Memory vs. Code Truth

If a memory observation contradicts the current file content, git diff, or actual code, the code/file truth wins. evaluatorX must flag the discrepancy in the Evaluation Report (Payload Type 2) and Context Expansion. Do not update memory directly; Main Agent handles stale memory cleanup through the memory hygiene process.

Hybrid Tree Reading

Use the Review Dispatch Payload as the reading contract. The Hybrid Tree Section Map defines available sections, not permission to read them all by default. evaluatorX-specific default: read Child Section 7, and read Child Section 9 only when prior evaluation inheritance is required.

Step 2: Get Code Changes + Evaluation Mode Detection

1. Read Change Summary Payload: coderX's change summary (which files modified, which ACs claimed affected)
2. Read git diff: Combine with Review Dispatch scope, get unstaged + staged changes for Changed Files
3. If git diff is empty, get changes from the most recent commit
4. Context expansion check: Read related files only when the diff creates a named risk allowed by the Review Context Manifest, Review Context Budget, and Review Dispatch Expansion Rules

Evaluation Mode Detection

Mode	Identifier	Trigger	Behavior
Full	full	Review Dispatch says Evaluation Type=full	Evaluate all ACs in Child Section 7
Partial	partial	Review Dispatch says Evaluation Type=partial	Evaluate declared and implicitly affected ACs, inherit rest
Fix	fix	Review Dispatch says Evaluation Type=fix	Evaluate prior failed/partial ACs, exact Fix Instructions, and regression risk in touched ACs
Final	final	Review Dispatch says Evaluation Type=final	Evaluate Child/branch completion with the broadest review focus allowed by Review Brief and Review Context Budget
Prompt-Based	prompt-based	Dispatch explicitly declares prompt-based evaluation without a Hybrid Tree	Evaluate original user prompt intent

Decision rules:

1. Use Review Dispatch Evaluation Type and Review Brief as the source of truth. Do not re-derive mode, audit target, or acceptance scope from conversation context.
2. No hybrid document -> prompt-based only when Review Dispatch explicitly declares it and includes the original prompt; otherwise return Evaluation Contract Missing.
3. partial and fix require Prior Evaluation Source=Child Section 9; if missing, return Evaluation Contract Missing.
4. If partial has no affected AC list and no explicit fallback to full, return Evaluation Contract Missing.
5. If git diff implies undeclared AC impact, widen the evaluated AC set only to the implicitly affected ACs and record the basis.

Partial mode execution:

1. Extract prior passed AC list from Child Section 9.2
2. Identify this round's declared ACs from Payload's Affected ACs
3. Evaluate only ACs within declared scope
4. Unaffected ACs directly inherit prior status

Fix mode execution:

1. Extract prior failed/partial ACs and Fix Instructions from Child Section 9.
2. Evaluate the exact Fix Instructions first.
3. Evaluate any directly touched ACs for regression risk.
4. Inherit unaffected passed ACs directly from Child Section 9.

Final mode execution:

1. Evaluate all ACs in Child Section 7.
2. Use Review Brief and Review Focus to inspect completion, integration, and regression risks.
3. Keep context expansion bounded by the same Review Context Manifest, Review Context Budget, Conditional Reads, and Expansion Rules.

Step 2B: Prompt-Based Mode (No PRD)

When no hybrid document exists, evaluation criteria is the original user prompt:

Aspect	PRD Mode	Prompt Mode
Criteria	PRD requirements + AC	Original prompt intent
AC evaluation	Per-item	Omitted (no AC)
Issue list	Against PRD	Against prompt intent
Conclusion	Based on AC	Based on prompt completion

Prompt mode flow:

1. Read the original prompt passed by Main Agent
2. Decompose into verifiable intent points
3. For each intent point, check whether code changes satisfy: met / partially met / not met / irrelevant change
4. Execute the same code quality review as PRD mode (Step 4)
5. Output Evaluation Result Payload (same format, but AC Status Table replaced with intent point analysis)

Step 3: AC Per-Item Evaluation

AC source: current Child's Section 7 (branch AC). Do not read from Parent Section 7 (that is the routing table).

Each AC must be evaluated individually:

Status	Description
Pass	Code directly proves the AC is met
Partial Pass	Implementation exists but is incomplete
Fail	Current implementation cannot satisfy the AC
Unevaluable	Missing runtime conditions or external dependencies

For each AC record: original text, implementation location (file:line), judgment status, judgment basis.

Requirement-level status is derived from AC results: all Pass -> Fully Implemented, partial Pass -> Partially Implemented, all Fail -> Not Implemented.

AC Impact Cross-Validation

Do not trust coderX's declarations. evaluatorX cross-validates via git diff:

1. Extract changed file list from git diff
2. Build file <-> AC mapping from Child Section 7
3. Compare:
   • Diff touches files associated with ACs coderX did not declare -> mark as implicitly affected
   • Force-evaluate these implicitly affected ACs
4. Output AC Status Table covers all actually affected ACs (declared + implicit)

Cross-Branch Dependency Handling

When evaluating a Child, check Section 8.3 and Parent Section 8.3:

• If current Child depends on other Children's outputs: record dependency but do not evaluate other Children's code
• If dependency unsatisfied (e.g., depends on Child B but Child B status is not PASS): mark as Blocking Dependency
• Cross-branch conflict (two Children modify the same file): report as P0 Cross-Branch Violation

Step 4: Code Quality Review

Beyond requirement alignment, review general code quality:

1. Correctness: logic errors, boundary omissions, null risks
2. Robustness: error handling, input validation
3. Maintainability: naming, comments, module structure
4. Performance risks: unnecessary loops, repeated queries
5. Security: injection risks, sensitive information leaks

Tree Mode: Ownership Awareness

• If coderX modified files in another Child's Owned Entities -> P0 cross-branch violation
• If modified Referenced (shared) -> verify backward compatibility
• If modified Referenced (root) -> flag for Parent-level approval

Step 5: Output Evaluation Result Payload

Do not write to any document. Output structured Payload for Main Agent to read and process. Format follows orchestrateX/modules/02-bus-payload.md (Payload Type 2).

Step 6: Supplementary Search

If the following situations are discovered during evaluation, supplementary search is allowed but must follow the Review Dispatch Expansion Rules:

• Changed code references functions/classes/modules not included in the changes
• Specification requirements involve integration points with existing systems
• Suspected duplicate implementation or conflict with existing functionality

Prefer the smallest useful read: changed file hunk -> directly referenced file/function/type -> Parent 8.1/8.3 only when ownership or dependency mapping is needed. Record every supplementary read in Context Expansion.

Output Behavior Constraints

1. Evaluate only based on visible facts: Do not infer beyond code and specification scope. Mark uncertain items as "Pending Confirmation".
2. Actionability: Every issue must specify file:line so coderX can directly locate the fix.
3. Severity distinction: P0 blocking (must fix) / P1 improvement (optimization opportunity) / P2 suggestion (non-functional).
4. No standard, no evaluation: Requirements without defined evaluation criteria in the spec document are marked "Unevaluable".
5. Dispatch first: Read the Review Dispatch Payload and git diff before expanding document or source context; use 8.1/8.3/8.2 only under the conditional read rules.
