Rejection Criteria:
  • Missing any of the above elements
  • Contains external links that redirect users off-platform
  • Excessively long (>150 words). (Note: Most current agents are image-generation focused and do not require lengthy explanations.)

4. Advantages

Requirements:
  • Presented as bullet points
  • Each point highlights a distinct, non-generic advantage
Examples (Approved):
  • ✔️ One-click publishing across multiple platforms
  • ✔️ Auto-generates titles and SEO keywords
Examples (Rejection):

5. Key Features

Requirements:
  • Bullet-point format, ordered by importance
  • Alignment with actual operating functions and avoidance of exaggerated effects
Examples (Approved):
  • ✔️ Input a topic → outputs a complete blog post
  • ✔️ Supports bilingual output (Chinese/English)
Examples (Rejection):
  • “Powerful AI engine”
  • “Accepts input in any language”

6. Prompts (Usage Guidance)

Requirements:
  • Instructs users on how to phrase inputs for optimal results
  • Provides concrete examples (e.g., “Input: ‘I want to write an article about running.’ ”)
  • (Note: Ready to use at a glance—no prompt needed.)
Rejection if:
  • Only says “Please enter content.”

7. Showcase / Cover Image

Requirements:
  • Provide at least three cover images
  • Each cover image needs to clearly display the agent’s actual output
  • No irrelevant stock images, placeholders, or excessive watermarks

  • Resolution ≥ 512×512 px
Examples (Rejection):

II. Safety Review

All content must comply with the following:
  • ❌ No explicit, pornographic, or violent content
  • ❌ No references to politics, religion, or sensitive events
  • ❌ No privacy violations, fraud inducement, or false advertising
  • ❌ No covert promotion (e.g., unsolicited links to Discord, X/Twitter, Facebook, or external websites)
Note: External references (e.g., Input template) are acceptable if necessary for context — but aggressive self-promotion or personal contact info is prohibited.

III. Experience Evaluation Criteria

1. Language Consistency

Input LanguageRequired Output LanguageAllowed Internal Processing Language(s)
ChineseChineseChinese or English
EnglishEnglishEnglish only
Japanese, Spanish, Portuguese, French, German, KoreanMust match input languageEnglish or the same target language
* ( Note: Internal processing may use English for model inference, but final output must strictly adhere to the input language.) ⚠️ Rejection if:
  • Unjustified language mixing (e.g., English input → Chinese output)
Note: Language consistency checks are not required for pure images or pure audio/video—only when visible/overlayed text is included.

2. Functional Availability

File Upload Support

Format TypeExamplesRequired?
Common formats✅ JPG, PNG, WebP, JPEGMandatory
Newer formats✅ GIF, AVIFOptional (recommended)
Special formatsSVG, PDF, HEICOptional (recommended)
⚠️ Rejection if:
  • Claims image processing support but fails on JPG, PNG, WebP, JPEG
  • The agent claims to support file processing (e.g., Excel, Word, and PDF documents), but the input interface does not allow file uploads.
Note: All upload restrictions (e.g., “1 image only”) must be visible in the input prompt/interface, and enforced in code (e.g. Up to 1 files).

Output File Download

  • All generated files (images, videos, PDFs, etc.) must be downloadable
  • Verification: Click “Download” → confirm successful file save
  • File Integrity Check: For text-based files (e.g., PDFs with selectable text, CSV): Ensure content is human-readable with no encoding errors (e.g., symbols), extraneous whitespace, or corrupted characters. For binary files (e.g., JPG, PNG, MP4): Ensure the file is non-empty, not truncated, and renders/opens without errors.
Note: As long as users can access/retrieve the output(e.g. HTMLs), the requirement is satisfied. Note: The image output must be rendered directly at the end of the workflow—not merely provided as a URL.

Clickable Output URLs

  • All links must be functional and lead to valid, safe destinations
  • Must not be broken (e.g., http://error) or redirect to malicious/blacklisted sites

3. Ease of Use

User input requirements should not be too stringent; minimize the number of input steps and the amount of uploaded materials:
Input TypeAcceptableUnacceptable
File Upload1–5 imagesRequiring ≥20 images
Text Input50–200 wordsRequiring ≥500 words
Multi-turn Dialog3–5 rounds maxForcing ≥8 rounds before output
⚠️ Rejection if:
  • Entry barrier is excessively high, harming UX
  • Requires users to manually edit/Photoshop input images

4. Minimum Output Quality

Text
  • No severe hallucinations (e.g., fabricating non-existent facts)
  • No common-sense violations
  • Occasional word blocking is acceptable and can be tolerated.
❌ Reject: frequent or patterned censorship URLs
  • Links must be real and accessible
  • No mass generation of invalid or shortened links
Images
  • Resolution ≥ 512×512 px
  • Clear, coherent visuals; minimal artifacts/distortions
  • Artistic nudity permitted (e.g., classical sculptures); explicit sexual content prohibited
  • For outfit-transfer agents: approve if changes are imperceptible (within 10% difference) or visually ambiguous
  • ❌ Reject: cropped/incomplete outputs or severely blurred images
Videos
  • No glaring physical/logical errors (e.g., walking upside-down)
  • Smooth playback; no stuttering or frame tearing

IV. Common Rejection Cases

  • Issue Type: ❌ Vague Information
  • Example: Name: “Smart Writing Tool” — no specific functionality described
  • Issue Type: ❌ Language Inconsistency
  • Example: English input → full Chinese output
  • Issue Type: ❌ Missing Functionality
  • Example: Claims “PDF parsing supported”, but upload fails with error
  • Issue Type: ❌ Low-Quality Output
  • Example: Generated image: 256×256, blurry
  • Issue Type: ❌ Safety Violation
  • Example: Showcase image contains politically sensitive symbols
  • Issue Type: ❌ Covert Promotion
  • Example: Output includes: “Add me on Telegram: xxx”
  • Issue Type: ❌ Insufficient Runtime Stability
  • Requirement: Each submitted version must have 5 consecutive successful runs before UTC 23:59 on the day of submission
  • Example 1: New version has only 3 successful runs → Rejected
  • Example 2: New version has 5 runs but only 4 successful and 1 failed → Rejected (runs must be consecutive)
