Add detailed file index and enhance skill documentation for autopilot, decompose, deploy, plan, and research skills. Introduce tests-only mode in decompose skill, clarify required files for deploy and plan skills, and improve prerequisite checks across skills for better user guidance and workflow efficiency.

+# E2E Test Data Management
+
+## Seed Data Sets
+
+| Data Set | Description | Used by Tests | How Loaded | Cleanup |
+|----------|-------------|---------------|-----------|---------|
+| onnx-model | Small YOLO ONNX model (valid architecture, 1280×1280 input, 19 classes) | All detection tests | Volume mount to mock-loader `/models/azaion.onnx` | Container restart |
+| classes-json | classes.json with 19 detection classes, 3 weather modes, MaxSizeM values | All tests | Volume mount to detections `/app/classes.json` | Container restart |
+| small-image | JPEG image 640×480 — below 1.5× model size (1920×1920 threshold) | FT-P-03, FT-P-05, FT-P-06, FT-P-07, FT-N-01, FT-N-02, NFT-PERF-01 | Volume mount to consumer `/media/` | N/A (read-only) |
+| large-image | JPEG image 4000×3000 — above 1.5× model size, triggers tiling | FT-P-04, FT-P-16, NFT-PERF-03 | Volume mount to consumer `/media/` | N/A (read-only) |
+| test-video | MP4 video, 10s duration, 30fps — contains objects across frames | FT-P-10, FT-P-11, FT-P-12, NFT-PERF-04 | Volume mount to consumer `/media/` | N/A (read-only) |
+| empty-image | Zero-byte file | FT-N-01 | Volume mount to consumer `/media/` | N/A (read-only) |
+| corrupt-image | Binary garbage (not valid image format) | FT-N-02 | Volume mount to consumer `/media/` | N/A (read-only) |
+| jwt-token | Valid JWT with exp claim (not signature-verified by detections) | FT-P-08, FT-P-09 | Generated by consumer at runtime | N/A |
+
+## Data Isolation Strategy
+
+Each test run starts with fresh containers (`docker compose down -v && docker compose up`). The detections service is stateless — no persistent data between runs. Mock services reset their state on container restart. Tests that modify mock behavior (e.g., making loader unreachable) must run in isolated test groups.
+
+## Input Data Mapping
+
+| Input Data File | Source Location | Description | Covers Scenarios |
+|-----------------|----------------|-------------|-----------------|
+| data_parameters.md | `_docs/00_problem/input_data/data_parameters.md` | API parameter schemas, config defaults, classes.json structure | Informs all test input construction |
+
+## External Dependency Mocks
+
+| External Service | Mock/Stub | How Provided | Behavior |
+|-----------------|-----------|-------------|----------|
+| Loader Service | HTTP stub | Docker service `mock-loader` | Serves ONNX model from volume on `GET /models/azaion.onnx`. Accepts TensorRT upload on `POST /upload`. Returns 404 for unknown files. Configurable: can simulate downtime (503) via control endpoint `POST /mock/config`. |
+| Annotations Service | HTTP stub | Docker service `mock-annotations` | Accepts annotation POST on `POST /annotations` — stores in memory for verification. Provides token refresh on `POST /auth/refresh`. Configurable: can simulate downtime (503) via control endpoint `POST /mock/config`. Returns recorded annotations on `GET /mock/annotations` for test assertions. |
+
+## Data Validation Rules
+
+| Data Type | Validation | Invalid Examples | Expected System Behavior |
+|-----------|-----------|-----------------|------------------------|
+| Image file (POST /detect) | Non-empty bytes, decodable by OpenCV | Zero-byte file, random binary, text file | 400 Bad Request |
+| media_id (POST /detect/{media_id}) | String, unique among active detections | Already-active media_id | 409 Conflict |
+| AIConfigDto fields | probability_threshold: 0.0–1.0; frame_period_recognition: positive int; big_image_tile_overlap_percent: 0–100 | probability_threshold: -1 or 2.0; frame_period_recognition: 0 | System uses defaults or returns validation error |
+| Authorization header | Bearer token format | Missing header, malformed JWT | Token forwarded to Annotations as-is; detections still proceeds |
+| classes.json | JSON array of objects with Id, Name, Color, MaxSizeM | Missing file, empty array, malformed JSON | Service fails to start / returns empty detections |
