Convert Screenshot Any

Use when (1) Convert a screenshot of any UI into a detailed prompt for AI image generation.

Core Position

This skill transforms input data from one format into a target format, preserving structure and fidelity. It is NOT a simple copy-paste — it handles formatting, schema mapping, and edge cases.

Key responsibilities:

• Parse the input format (JSON/CSV/code/etc.) and validate structure before transforming
• Apply formatting rules specific to the target format (indentation, escaping, etc.)
• Handle edge cases: missing fields, unusual characters, nested structures
• Provide a clear mapping summary so the user understands how input maps to output

Modes

/convert-screenshot-any --pretty

Formatted output. Applies proper indentation, spacing, and style conventions.

/convert-screenshot-any --strict

Strict mode. Fails on any deviation from expected structure rather than guessing.

Execution Steps

1. Parse input — Read and parse the input; detect format (JSON/CSV/XML/code/etc.)
   • If parsing fails, report: "Failed to parse input as [format] — error at line [N]: [detail]"
2. Validate structure — Check required fields/columns are present
   • If missing required field X, stop and report: "Missing required field: [X]"
3. Transform — Convert input to target format, applying format-specific rules
   • Preserve all data — do not silently drop fields
   • Apply proper escaping for special characters (quotes, newlines, etc.)
4. Validate output — Run the target format parser on the result to confirm it's valid
   • If output is invalid, revert to previous version and report what went wrong
5. Deliver — Return the converted output with a brief mapping summary

Mandatory Rules

Do not

• Do not silently drop fields or data — if a field cannot be mapped, report it
• Do not guess at missing data — if a field is absent, leave it null/empty and flag it
• Do not apply formatting that destroys the semantic meaning of the data
• Do not produce output that fails the target format validator
• Do not convert binary data as if it were text — detect and handle binary separately

Do

• Report the complete field mapping: [source] -> [target] for every field
• Validate input and output formats before and after transformation
• Preserve character encoding (UTF-8) throughout the conversion process
• Handle large inputs in chunks if needed to avoid memory exhaustion
• Log conversion statistics: fields mapped, fields dropped, warnings issued

Quality Bar

Criterion	Minimum	Ideal
Data fidelity	Zero data loss — all fields mapped	Full semantic equivalence, not just structural
Format validity	Output passes target parser	Output passes strict schema validation
Edge case handling	Handles missing/null/empty gracefully	Documents every edge case decision
Escaping correctness	Proper escaping for target format	Round-trip: convert back to source equals original
Performance	Completes within 2x manual time	Streaming output for large inputs

A good output passes the target format parser without errors and preserves all semantic content.

Good vs. Bad Examples

Scenario	Bad	Good
Missing field	Omits field from output silently	Reports "Field [X] absent — output null, flagged as warning"
Special characters	Only escapes visible chars	Escapes all special chars per target format spec
Large input	Loads entire file into memory	Streams in chunks, reports progress at 25/50/75%
Output validation	Skips validation	Runs target parser on output, confirms valid before returning
Format error	Returns raw output with error text appended	Returns nothing, reports "Output invalid: [parser error] at [location]"
