# Rubric Library: five rules and a five-check script (free sample)

> From the Rubric Library: five rules for the scoring inside agent workflows (a human owns the library, every rubric has a number, every grade says what it means and what it triggers, people, clients and money go to a person, no profiling people who did not opt in), and a read-only script that checks one rubric file for them.

## What you end up with

In a few minutes you can see whether the scores your agents produce rest on a written rubric or on a guess.

## What you get

- Five rubric rules
- rubric_mini.py: five read-only checks on one rubric-lite.json
- One prompt for all four harnesses
- Worked example: 5 findings, then 0

## Who it is for

Anyone who wants a quick check of the rubrics behind their agents' scores before trusting them with more.

## Tools needed

- Grok Bot, Claude Code, Codex or Hermes: the agent that scores; it reads the skill file, AGENTS.md snippet or rules block, loads a named rubric version with rubric.py load and checks each score with rubric.py check-score
- Python 3: runs rubric.py (load, check-score, owner approval, verify, done) and the fifteen-check checker; standard library only, no network
- You need: Python 3.9 or newer
- You need: Any of Grok Bot, Claude Code, Codex or Hermes

Cost to run: Free.

## Sample prompt: Find the rubrics you already use (Grok Bot, Claude Code, Codex, Hermes)

```
Look through the last month of prompts where I asked you to score, rank, grade or triage anything. For each, write down the rubric you were actually using: the grades, what each meant and what it led to. Mark every place you guessed. Do not change anything.
Run rubric_mini.py rubric-lite.json and show me the findings.
```

The rules and the script are in the file.

# Rubric Library: five rules and a five-check script (free sample)

Version 1.0, 2026-10-28. By PaperChaseWebb. For anyone who lets an agent score, grade or triage things, in Grok Bot, Claude Code, Codex, Hermes or a mix, and wants the scoring rules written down where the agent can load them. One Markdown file and one Python 3 script, standard library only. The script was tested on its worked example (5 findings, then 0) and on a missing file (exit 2). It was not run inside any agent harness or on a real scoring workflow.

Every "score these leads", "triage this inbox" or "rank these posts" prompt has a rubric in it. Usually it lives in one person's head or one chat thread, has no version, and changes a little every time someone rewrites the prompt. The scores look precise and mean whatever the agent guessed that day. The rubric is the product: write it down, give it an owner and a number, and say what each grade makes happen. These five rules cover the gaps that cost the most, and the script checks them in one small file.

## Five rules

1. **Every rubric library has a human owner.** A person decides what the grades mean. Not "TBD", and not the agent doing the scoring.
2. **Every rubric has a number.** An agent loads hook-patt

## Test record

- Date: Oct 28, 2026
- What was run: rubric_mini.py on the worked example, a fixed file and a missing file.
- Result: 5 findings, then 0; exit 2 on a missing file.
- Not run: The prompt inside a harness.

Copied from this item's dated test notes. What was not run stays in.

## Worth knowing

- The sample checks one file against five rules. The six-file library, evidence rules, borderline and adversarial cases, load and check-score, owner approvals by hash and the fifteen checks are in the full pack.
- On 2026-10-28 rubric_mini.py gave 5 findings on the worked example, then 0 on the fixed file, and exited 2 on a missing file. The prompt was not run inside a harness.

## Questions

**Does it send anything anywhere?** No. It reads one file and opens no network connection.

**What is in the full pack?** The six-file library with templates, rubric.py that your agents load rubrics from and check scores against, owner approvals tied to a hash with one use and expiry, fifteen read-only checks with a seeded test library, a skill file, AGENTS.md snippet and Grok Bot rules block, ten prompts and a failure table. $19.
