+# Unity NL/T Editing Suite — Additive Test Design
+
+You are running inside CI for the `unity-mcp` repo. Use only the tools allowed by the workflow. Work autonomously; do not prompt the user. Do NOT spawn subagents.
+
+**Print this once, verbatim, early in the run:**
+AllowedTools: Write,mcp__unity__manage_editor,mcp__unity__list_resources,mcp__unity__read_resource,mcp__unity__apply_text_edits,mcp__unity__script_apply_edits,mcp__unity__validate_script,mcp__unity__find_in_file,mcp__unity__read_console,mcp__unity__get_sha
+
+---
+
+## Mission
+1) Pick target file (prefer):
+   - `unity://path/Assets/Scripts/LongUnityScriptClaudeTest.cs`
+2) Execute **all** NL/T tests in order using minimal, precise edits that **build on each other**.
+3) Validate each edit with `mcp__unity__validate_script(level:"standard")`.
+4) **Report**: write one `<testcase>` XML fragment per test to `reports/<TESTID>_results.xml`. Do **not** read or edit `$JUNIT_OUT`.
+5) **NO RESTORATION** - tests build additively on previous state.
+
+---
+
+## Environment & Paths (CI)
+- Always pass: `project_root: "TestProjects/UnityMCPTests"` and `ctx: {}` on list/read/edit/validate.
+- **Canonical URIs only**:
+  - Primary: `unity://path/Assets/...` (never embed `project_root` in the URI)
+  - Relative (when supported): `Assets/...`
+
+CI provides:
+- `$JUNIT_OUT=reports/junit-nl-suite.xml` (pre‑created; leave alone)
+- `$MD_OUT=reports/junit-nl-suite.md` (synthesized from JUnit)
+
+---
+
+## Tool Mapping
+- **Anchors/regex/structured**: `mcp__unity__script_apply_edits`
+  - Allowed ops: `anchor_insert`, `replace_method`, `insert_method`, `delete_method`, `regex_replace`
+- **Precise ranges / atomic batch**: `mcp__unity__apply_text_edits` (non‑overlapping ranges)
+- **Hash-only**: `mcp__unity__get_sha` — returns `{sha256,lengthBytes,lastModifiedUtc}` without file body
+- **Validation**: `mcp__unity__validate_script(level:"standard")`
+- **Dynamic targeting**: Use `mcp__unity__find_in_file` to locate current positions of methods/markers
+
+---
+
+## Additive Test Design Principles
+
+**Key Changes from Reset-Based:**
+1. **Dynamic Targeting**: Use `find_in_file` to locate methods/content, never hardcode line numbers
+2. **State Awareness**: Each test expects the file state left by the previous test
+3. **Content-Based Operations**: Target methods by signature, classes by name, not coordinates
+4. **Cumulative Validation**: Ensure the file remains structurally sound throughout the sequence
+5. **Composability**: Tests demonstrate how operations work together in real workflows
+
+**State Tracking:**
+- Track file SHA after each test to ensure operations succeeded
+- Use content signatures (method names, comment markers) to verify expected state
+- Validate structural integrity after each major change
+
+---
+
+## Execution Order & Additive Test Specs
+
+### NL-0. Baseline State Capture
+**Goal**: Establish initial file state and verify accessibility
+**Actions**:
+- Read file head and tail to confirm structure
+- Locate key methods: `HasTarget()`, `GetCurrentTarget()`, `Update()`, `ApplyBlend()`
+- Record initial SHA for tracking
+- **Expected final state**: Unchanged baseline file
+
+### NL-1. Core Method Operations (Additive State A)
+**Goal**: Demonstrate method replacement operations
+**Actions**: 
+- Replace `HasTarget()` method body: `public bool HasTarget() { return currentTarget != null; }`
+- Insert `PrintSeries()` method after `GetCurrentTarget()`: `public void PrintSeries() { Debug.Log("1,2,3"); }`
+- Verify both methods exist and are properly formatted
+- Delete `PrintSeries()` method (cleanup for next test)
+- **Expected final state**: `HasTarget()` modified, file structure intact, no temporary methods
+
+### NL-2. Anchor Comment Insertion (Additive State B) 
+**Goal**: Demonstrate anchor-based insertions above methods
+**Actions**:
+- Use `find_in_file` to locate current position of `Update()` method
+- Insert `// Build marker OK` comment line above `Update()` method
+- Verify comment exists and `Update()` still functions
+- **Expected final state**: State A + build marker comment above `Update()`
+
+### NL-3. End-of-Class Content (Additive State C)
+**Goal**: Demonstrate end-of-class insertions with smart brace matching
+**Actions**:
+- Use anchor pattern to find the class-ending brace (accounts for previous additions)
+- Insert three comment lines before final class brace:
+  ```
+  // Tail test A
+  // Tail test B  
+  // Tail test C
+  ```
+- **Expected final state**: State B + tail comments before class closing brace
+
+### NL-4. Console State Verification (No State Change)
+**Goal**: Verify Unity console integration without file modification
+**Actions**:
+- Read Unity console messages (INFO level)
+- Validate no compilation errors from previous operations
+- **Expected final state**: State C (unchanged)
+
+### T-A. Temporary Helper Lifecycle (Returns to State C)
+**Goal**: Test insert → verify → delete cycle for temporary code
+**Actions**:
+- Find current position of `GetCurrentTarget()` method (may have shifted from NL-2 comment)
+- Insert temporary helper: `private int __TempHelper(int a, int b) => a + b;`
+- Verify helper method exists and compiles
+- Delete helper method via structured delete operation
+- **Expected final state**: Return to State C (helper removed, other changes intact)
+
+### T-B. Method Body Interior Edit (Additive State D)
+**Goal**: Edit method interior without affecting structure, on modified file
+**Actions**:
+- Use `find_in_file` to locate current `HasTarget()` method (modified in NL-1)
+- Edit method body interior: change return statement to `return true; /* test modification */`
+- Use `validate: "relaxed"` for interior-only edit
+- Verify edit succeeded and file remains balanced
+- **Expected final state**: State C + modified HasTarget() body
+
+### T-C. Different Method Interior Edit (Additive State E)
+**Goal**: Edit a different method to show operations don't interfere
+**Actions**:
+- Locate `ApplyBlend()` method using content search
+- Edit interior line to add null check: `if (animator == null) return; // safety check`
+- Preserve method signature and structure  
+- **Expected final state**: State D + modified ApplyBlend() method
+
+### T-D. End-of-Class Helper (Additive State F)
+**Goal**: Add permanent helper method at class end
+**Actions**:
+- Use smart anchor matching to find current class-ending brace (after NL-3 tail comments)
+- Insert permanent helper before class brace: `private void TestHelper() { /* placeholder */ }`
+- **Expected final state**: State E + TestHelper() method before class end
+
+### T-E. Method Evolution Lifecycle (Additive State G)
+**Goal**: Insert → modify → finalize a method through multiple operations
+**Actions**:
+- Insert basic method: `private int Counter = 0;`
+- Update it: find and replace with `private int Counter = 42; // initialized`
+- Add companion method: `private void IncrementCounter() { Counter++; }`
+- **Expected final state**: State F + Counter field + IncrementCounter() method
+
+### T-F. Atomic Multi-Edit (Additive State H)
+**Goal**: Multiple coordinated edits in single atomic operation
+**Actions**:
+- Read current file state to compute precise ranges
+- Atomic edit combining:
+  1. Add comment in `HasTarget()`: `// validated access`  
+  2. Add comment in `ApplyBlend()`: `// safe animation`
+  3. Add final class comment: `// end of test modifications`
+- All edits computed from same file snapshot, applied atomically
+- **Expected final state**: State G + three coordinated comments
+
+### T-G. Path Normalization Test (No State Change)
+**Goal**: Verify URI forms work equivalently on modified file
+**Actions**:
+- Make identical edit using `unity://path/Assets/Scripts/LongUnityScriptClaudeTest.cs`
+- Then using `Assets/Scripts/LongUnityScriptClaudeTest.cs` 
+- Second should return `stale_file`, retry with updated SHA
+- Verify both URI forms target same file
+- **Expected final state**: State H (no content change, just path testing)
+
+### T-H. Validation on Modified File (No State Change)
+**Goal**: Ensure validation works correctly on heavily modified file
+**Actions**:
+- Run `validate_script(level:"standard")` on current state
+- Verify no structural errors despite extensive modifications
+- **Expected final state**: State H (validation only, no edits)
+
+### T-I. Failure Surface Testing (No State Change)
+**Goal**: Test error handling on real modified file
+**Actions**:
+- Attempt overlapping edits (should fail cleanly)
+- Attempt edit with stale SHA (should fail cleanly) 
+- Verify error responses are informative
+- **Expected final state**: State H (failed operations don't modify file)
+
+### T-J. Idempotency on Modified File (Additive State I)
+**Goal**: Verify operations behave predictably when repeated
+**Actions**:
+- Add unique marker comment: `// idempotency test marker`
+- Attempt to add same comment again (should detect no-op)
+- Remove marker, attempt removal again (should handle gracefully)
+- **Expected final state**: State H + verified idempotent behavior
+

+
+## Dynamic Targeting Examples
+
+**Instead of hardcoded coordinates:**
+```json
+{"startLine": 31, "startCol": 26, "endLine": 31, "endCol": 58}
+```
+
+**Use content-aware targeting:**
+```json
+# Find current method location
+find_in_file(pattern: "public bool HasTarget\\(\\)")
+# Then compute edit ranges from found position
+```
+
+**Method targeting by signature:**
+```json
+{"op": "replace_method", "className": "LongUnityScriptClaudeTest", "methodName": "HasTarget"}
+```
+
+**Anchor-based insertions:**
+```json  
+{"op": "anchor_insert", "anchor": "private void Update\\(\\)", "position": "before", "text": "// comment"}
+```
+
+---
+
+## State Verification Patterns
+
+**After each test:**
+1. Verify expected content exists: `find_in_file` for key markers
+2. Check structural integrity: `validate_script(level:"standard")`  
+3. Update SHA tracking for next test's preconditions
+4. Log cumulative changes in test evidence
+
+**Error Recovery:**
+- If test fails, log current state but continue (don't restore)
+- Next test adapts to actual current state, not expected state
+- Demonstrates resilience of operations on varied file conditions
+
+---
+
+## Benefits of Additive Design
+
+1. **Realistic Workflows**: Tests mirror actual development patterns
+2. **Robust Operations**: Proves edits work on evolving files, not just pristine baselines  
+3. **Composability Validation**: Shows operations coordinate well together
+4. **Simplified Infrastructure**: No restore scripts or snapshots needed
+5. **Better Failure Analysis**: Failures don't cascade - each test adapts to current reality
+6. **State Evolution Testing**: Validates SDK handles cumulative file modifications correctly
+
+This additive approach produces a more realistic and maintainable test suite that better represents actual SDK usage patterns.
