The useful result
Turn one image edit into a short allowed-change and invariant checklist.
- Turn one image edit into a short allowed-change and invariant checklist.
- Use the explicit result checks to identify a failed or uncertain outcome.
FIBO’s current editing demo exposes structured instructions through its VGL writer. A structured format is useful only if it expresses the edit you intend. This lesson teaches a portable review habit: identify the requested delta, preserve the scene contract and inspect the candidate against the original. It does not invent a universal JSON schema.
Before you start
- An owned practice image and one simple edit goal.
- The actual current FIBO demo or documented writer if you want to inspect VGL.
Review evidence
Documentation-based review · 2026-10-27
Primary documentation and demo source reviewed on 27 October 2026. Exercises and expected results are illustrative unless an actual test is explicitly recorded. Local editorial review only; no provider-performance or audience outcome is claimed.
Write one change and three invariants
For an original teapot image, change the lid from sage to coral. Preserve body color, handle shape and camera. Record these before touching any structured fields. The key is whether a detail is allowed to change, not whether a particular sentence sounds artistic.
Example / expected result
Illustrative example; not tested on the named platform.
Allowed: lid color. Fixed: body, handle and camera.
Check your result
The brief contains one measurable visible change and a short list of fixed details.
Compare the writer output with the brief
Use the tool’s actual generated instruction or current documented schema. Look for added scene changes, replaced subject descriptions or contradictory colors. Keep unrecognized fields intact until you understand their documented role.
Review this supplied edit instruction against my contract. Identify intended changes, unintended changes and contradictions. Do not invent VGL keys or rewrite undocumented fields. Contract: lid coral; body, handle and camera unchanged.Example / expected result
Illustrative example; not tested on the named platform.
A sentence changing “studio background” to “garden” is an unintended second edit.
Check your result
The proposed instruction agrees with the contract, or unresolved fields are explicitly flagged.
Inspect changed and fixed regions separately
After an authorized generation, check the lid first. Then check the three invariants at the same display size as the original. Reject a candidate that achieves the lid color by changing the whole teapot. Keep a short pass/fail note.
Example / expected result
Illustrative example; not tested on the named platform.
Review: lid PASS; body PASS; handle FAIL because its shape changed.
Check your result
The acceptance decision considers fixed details as well as the requested change.
When it goes wrong
The cover is conceptual art, not a FIBO test. Structured instructions and masks do not guarantee preservation. Use current access and license terms, and do not claim successful editing without inspecting a real result.
Make it your own
Change only the background of an owned still life. Add three invariants, inspect the real instruction and compare one candidate against the untouched source.
