# Evaluation: qwen3_coder_next_gguf

## Criterion 1: Did it only list snippets, or also tell what to implement?

**Verdict: Failed this criterion.** The prompt explicitly said "DON'T CHANGE ANY CODE, JUST GIVE ME THE SNIPPETS I NEED," but the response is heavily laced with implementation guidance:

- Snippet 1: "You'll see how text is positioned and can learn to insert an image before it."
- Snippet 3: "You'll need to extend this to support a prefix image (e.g., `prefixImage: UIImage?`, `prefixImageWidthRatio: CGFloat`)."
- Snippet 6: "You'll want to add something like `drawPrefixImage(in:context:titleFrame:imageWidth:)`."
- Snippet 7: "You'll adjust this to insert an image *before* the title text."
- Snippet 8: "You'll need to extend this call and `decorate(...)` signature."
- The summary table includes implementation verbs like "Extend to support prefix image" and "Reusable helper to draw custom image."

The model turned what should have been a pure snippet extraction into a mini implementation guide.

## Criterion 2: Did it find all the related places?

**What it found (8 areas):**
- Title rendering in `decorate()` — correct
- Title area height calculation — correct
- Configuration struct fields (partial) — correct but incomplete
- Title text generation (`titleText` computed property) — correct
- UI controls (ExportSheet body + state vars) — correct
- Drawing helper functions (`drawDecorations`) — correct
- Title/subtitle positioning layout (titleAreaY, mapFrameY) — correct
- Call site in `generatePreview` — correct

**What it missed:**
- `decoratorConfig` computed property (lines 338–417) — this is the critical bridge where ExportSheet state vars flow into the Configuration. Any new config field must be wired through here
- Configuration `init(from decoder:)` / `encode(to:)` (Codable conformance, lines 3187–3310) — must be updated for any new config field
- Configuration memberwise `init(...)` (lines 3337–3415) — must add new parameters here
- Configuration builder/mutating methods (e.g., `withTitleFontName`, lines 3417–3470+) — would need a new `withPrefixImage(...)` method
- CodingKeys enum (line 3171–3184) — must add new key
- Template presets (artDeco, bauhaus, noir, etc., lines 4346–5070+) — each preset would need a default value for the new field
- The `decorate()` function signature itself (line 3692–3697) — if the image is passed as a parameter rather than stored in config
- The `fittedFont` / `alignedX` helper implementations — relevant for understanding how to position the image relative to text
- Hashing logic (lines 164–204) — must include new fields for preview cache invalidation
- Other call sites of `decorate()` (lines 2069, 2182) — not just the preview, also the actual export

## Line Number Accuracy

The model fabricated line numbers that don't match the actual file at all:
- Claims title rendering is "around line ~600–750" — actual: ~3908–3943
- Claims height calc is "around line ~460–500" — actual: ~3738–3766
- Claims drawDecorations is "around line ~980+" — actual: ~4245
- Claims generatePreview is "around line ~1750–1780" — actual: ~1793–1799 (this one is close but still off)

## Code Snippet Accuracy

The snippets shown are structurally correct but appear partially reconstructed rather than verbatim. Some details are truncated with `...` which is reasonable for brevity, but the Configuration snippet (Snippet 3) is misleadingly incomplete — it omits most fields and gives the impression the struct is much simpler than it actually is.

## Grade: **C+**

**Strengths:** Good structural understanding of the codebase, identified the major areas, well-organized response with clear sections and a summary table.

**Weaknesses:** Violated the core instruction ("just give me the snippets") by adding implementation guidance throughout; missed several critical areas needed for a complete implementation (Codable, init, builder methods, template presets, decoratorConfig, other call sites); fabricated line numbers; showed incomplete snippets that understate the complexity of the Configuration struct.
