verify-everything 0.2.0

LLM-based code review tool that finds issues tests and linters miss

Vet is a standalone verification tool for code changes and coding agent behavior.

Why Vet

• Reviews intent and code: checks agent conversations for goal adherence and code changes for correctness.
• Runs anywhere: from the terminal, as an agent skill, or in CI.
• Bring-your-own-model: works with any provider using your own API keys, no subscription ever.
• No data collection: requests go directly to inference providers, never through our servers.

Using Vet with Coding Agents

Vet includes an agent skill. When installed, agents will proactively run vet after code changes to find issues with the new code and mismatches between the user's request and the agent's actions.

Install the skill

curl -fsSL https://raw.githubusercontent.com/imbue-ai/vet/main/install-skill.sh | bash

You will be prompted to choose between:

• Project level: installs into .agents/skills/vet/, .opencode/skills/vet/, .claude/skills/vet/, and .codex/skills/vet/ at the repo root (run from your repo directory)
• User level: installs into ~/.agents/, ~/.opencode/, ~/.claude/, and ~/.codex/ skill directories, discovered globally by all agents

Demo

Manual installation

Project Level

From the root of your git repo:

for dir in .agents .opencode .claude .codex; do
  mkdir -p "$dir/skills/vet/scripts"
  for file in SKILL.md scripts/export_opencode_session.py scripts/export_codex_session.py scripts/export_claude_code_session.py; do
    curl -fsSL "https://raw.githubusercontent.com/imbue-ai/vet/main/skills/vet/$file" \
      -o "$dir/skills/vet/$file"
  done
done

User Level

for dir in ~/.agents ~/.opencode ~/.claude ~/.codex; do
  mkdir -p "$dir/skills/vet/scripts"
  for file in SKILL.md scripts/export_opencode_session.py scripts/export_codex_session.py scripts/export_claude_code_session.py; do
    curl -fsSL "https://raw.githubusercontent.com/imbue-ai/vet/main/skills/vet/$file" \
      -o "$dir/skills/vet/$file"
  done
done

Security note

The --history-loader option executes the specified shell command as the current user to load the conversation history. It is important to review history loader commands and shared config presets before use.

Install the CLI

pip install verify-everything

Or install from source:

pip install git+https://github.com/imbue-ai/vet.git

Usage

Run Vet in the current repo:

vet "Implement X without breaking Y"

Compare against a base ref/commit:

vet "Refactor storage layer" --base-commit main

GitHub PRs (Actions)

Vet reviews pull requests using a reusable GitHub Action.

Create .github/workflows/vet.yml:

name: Vet

permissions:
  contents: read
  pull-requests: write

on:
  pull_request:
    types: [opened, edited, synchronize, reopened]

jobs:
  vet:
    if: github.event.pull_request.draft == false
    runs-on: ubuntu-latest
    env:
      ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
    steps:
      - uses: actions/checkout@v4
        with:
          ref: ${{ github.event.pull_request.head.sha }}
          fetch-depth: 0
      - uses: imbue-ai/vet@main
        with:
          agentic: false

The action handles Python setup, vet installation, merge base computation, and posting the review to the PR. ANTHROPIC_API_KEY must be set as a repository secret when using Anthropic models (the default). See action.yml for all available inputs.

How it works

Vet snapshots the repo and diff, optionally adds a goal and agent conversation, runs LLM checks, then filters/deduplicates findings into a final list of issues.

Output & exit codes

• Exit code 0: no issues found
• Exit code 1: unexpected runtime error
• Exit code 2: invalid usage/configuration error
• Exit code 10: issues found

Output formats:

• text
• json
• github

Configuration

Model configuration

Vet supports custom model definitions using OpenAI-compatible endpoints via JSON config files searched in:

• $XDG_CONFIG_HOME/vet/models.json (or ~/.config/vet/models.json)
• .vet/models.json at your repo root

Example models.json

{
  "providers": {
    "openrouter": {
      "name": "OpenRouter",
      "api_type": "openai_compatible",
      "base_url": "https://openrouter.ai/api/v1",
      "api_key_env": "OPENROUTER_API_KEY",
      "models": {
        "gpt-5.2": {
          "model_id": "openai/gpt-5.2",
          "context_window": 400000,
          "max_output_tokens": 128000,
          "supports_temperature": true
        },
        "kimi-k2": {
          "model_id": "moonshotai/kimi-k2",
          "context_window": 131072,
          "max_output_tokens": 32768,
          "supports_temperature": true
        }
      }
    }
  }
}

Then:

vet "Harden error handling" --model gpt-5.2

Configuration profiles (TOML)

Vet supports named profiles so teams can standardize CI usage without long CLI invocations.

Profiles set defaults like model choice, enabled issue codes, output format, and thresholds.

See the example in this project.

Custom issue guides

You can customize the guide text for the issue codes via guides.toml. Guide files are loaded from:

• $XDG_CONFIG_HOME/vet/guides.toml (or ~/.config/vet/guides.toml)
• .vet/guides.toml at your repo root

Example guides.toml

[logic_error]
suffix = """
- Check for integer overflow in arithmetic operations
"""

[insecure_code]
replace = """
- Check for SQL injection: flag any string concatenation or f-string formatting used to build SQL queries rather than parameterized queries
- Check for XSS: flag user-supplied data rendered into HTML templates without proper escaping or sanitization
- Check for path traversal: flag file operations where user input flows into file paths without validation against directory traversal (e.g. ../)
- Check for insecure cryptography: flag use of deprecated or weak algorithms (e.g. MD5, SHA1 for security purposes, DES, RC4)
- Check for hardcoded credentials: flag passwords, API keys, or tokens embedded directly in source code
"""

Section keys must be valid issue codes (vet --list-issue-codes). Each section supports three optional fields: prefix (prepends to built-in guide), suffix (appends to built-in guide), and replace (fully replaces the built-in guide). prefix and suffix can be used together, but replace is mutually exclusive with the other two. Guide text should be formatted as a list.
