What it does

Verifying Changes is an agent skill from BuilderIO/agent-native. Concrete, per-area proof that a change actually works before reporting it fixed, done, or "should work now" — which dev server, test command, or invocation proves a template UI change, an action, a migration, a guard, or a core/package change. Use before every wrap-up, and before stopping mid-task to ask permission instead of continuing.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A framework for building agentic apps.

Example prompts

  • “should work now”
  • “/verifying-changes”

What it can do on your machine

Read from SKILL.md and the folder at commit be0d784. 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:

    • pnpm
    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pnpm, 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

Verifying Changes loads about 1.8k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 1,017 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~89
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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 1,017 words (~1,815 tokens).

“Before telling the user a fix, feature, or bug is done, choose the smallest proof that exercises the behavior you changed and use the row below as a guide. "I changed the code and it looks right" is not proof…”
