What it does

Code Change Verification is an agent skill from openai/openai-guardrails-js, published by the product's own GitHub organization. Select and run Guardrails verification for code, dependency, test, tooling, documentation, or repository-workflow changes.

Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in AI & LLM Engineering, covering LLM guardrails. It works with npm. The repository describes itself as: OpenAI Guardrails - TypeScript / JavaScript. The licence is MIT.

When your agent uses it

  • Tasks that involve LLM guardrails

Example prompts

  • “/code-change-verification”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e88be0. 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
    • git

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

  • Network

    No URLs in SKILL.md. Its commands use npm and git, 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

Code Change Verification loads about 619 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 293 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~619

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.

Code Change Verification

Follow repository verification and inspect the current package.json scripts before selecting checks. Run from the selected linked worktree's root; preserve its branch and user-owned changes.

Select the evidence

Changed areaVerification
Runtime, public types, dependencies, build/test configuration, packagingFull sequence below; focused tests during implementation
SDK integration or dependency compatibilityBuild first, then the relevant src/__tests__/integration/sdk-*.test.ts tests; full sequence before handoff
Site content, links, navigation, or VitePress toolingnpm ci, then npm run docs:check
Contributor instructions or skill metadata onlyValidate commands, relative links, frontmatter/UI metadata, and git diff --check

When areas overlap, combine their required checks. A test described as "integration" is not necessarily live: inspect its fixtures and calls before running it. The normal suite uses local fixtures and mocks; do not turn ordinary verification into a credentialed eval or an external API experiment.

Full sequence

Run each command separately and inspect its exit status before proceeding:

sh
npm ci
npm run build
npm run test:run
npm run lint
npm run docs:check

The build emits CommonJS and declarations consumed by compatibility tests. test:run avoids watch mode. Biome lint includes formatting and import checks; VitePress and the Node documentation tests run through docs:check. Invoke npm directly in the host shell, including PowerShell; no platform-specific wrapper or additional formatter is needed.

Keep verification within the available sandbox. Diagnose failures and fix only in-scope defects; report unrelated failures and missing coverage. Retry a transient failure when evidence supports that diagnosis. After a fix, repeat checks whose evidence it invalidated. Never report a skipped or failed gate as passing, and do not infer Windows coverage from Linux or macOS results.

Report the command, result, tested Node version, and any coverage limits. For remote checks, associate the result with the current PR head. The review gate in AGENTS.md also applies before pushing; passing tests do not replace it.
