What it does
Fix Visual Stability is an agent skill from EtaYang10th/spark-skills. Fix visual stability issues in Next.js e-commerce apps — covers CLS (Cumulative Layout Shift), FOIT (Flash of Invisible Text), and theme flicker
Its SKILL.md is about 3.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `attempts.json`).
It sits in Sales & Support, covering E-commerce operations. It works with Next.js. The repository describes itself as: Evidence Over Plans: Online Trajectory Verification for Skill Distillation.
When your agent uses it
- Tasks that involve E-commerce operations
Example prompts
- “/fix-visual-stability”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Audit the codebase
- Identify which checks are failing
- Apply fixes in order
- Build and verify
What it can do on your machine
Read from SKILL.md and the folder at commit 733f19a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Fix Visual Stability loads about 3.7k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 735 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 735 words (~3,717 tokens).
“Visual stability issues in Next.js apps typically fall into four categories:”
