llm-gate skillA
llm-gate is agent-read markdown (skill) from rohitg00/pro-workflow: LLM-powered quality verification using prompt hooks. Validates commit messages, code patterns, and conventions using AI before allowing operations. Use to set up intelligent guardrails..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# LLM Gate
Use Claude Code's `type: "prompt"` hooks to create intelligent quality gates that use AI to verify operations.
## Trigger
Use when:
- Setting up commit message validation
- Enforcing code conventions beyond what linters catch
- Creating smart guardrails for specific operations
## How Prompt Hooks Work
Claude Code supports hooks with `type: "prompt"` that run a small LLM (Haiku by default) to verify conditions:
```json
{
"PreToolUse": [{
"matcher": "Bash",
"hooks": [{
"type": "prompt",
"if": "Bash(git commit*)",
"prompt": "Check if this git commit follows conventional commit format (<type>(<scope>): <summary>). The commit command is: $ARGUMENTS. Return {\"ok\": true} if valid, {\"ok\": false, \"reason\": \"...\"} if not.",
"model": "haiku",
"timeout": 15
}]
}]
}
```
The hook:
1. Substitutes `$ARGUMENTS` with the JSON hook input
2. Sends to Haiku (fast, cheap)
3. Expects `{"ok": true}` or `{"ok": false, "reason": "..."}`
4. If not ok → blocks the tool call with the reason
## Example Gates
### Conventional Commit Validator
```json
{
"type": "prompt",
"if": "Bash(git commit*)",

How to install
mdr add rohitg00/pro-workflow/llm-gate@git:20260331.68dbd4bmdr add rohitg00/pro-workflow/llm-gate@sha256:4b7da8e85e2041f8Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
