baseline

A command for recording the current code-quality violations in a project as an accepted starting point.

In plain words
What is it for?
Create a snapshot of existing findings, check only for new findings, or update the snapshot after fixing problems.
Why use it?
It lets teams adopt checks in an older codebase without being blocked by every existing problem. Only violations introduced later are reported as new.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo
git clone --depth 1 https://github.com/MilindGaharwar/fettle

Or install fettle, the plugin that ships this one along with the rest of its 34 commands, 4 hooks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

baseline scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

88% identical to fettle-baseline — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

/fettle:baseline

Manage violation baselines for gradual adoption.

Usage

Create baseline (snapshot current state)

fettle baseline create

Saves all current findings to .fettle-baseline.json. These findings are grandfathered.

Check against baseline (only new violations)

fettle check --baseline

Update baseline (after fixing some findings)

fettle baseline update

Purpose

Allows adoption in legacy repos without fixing all existing issues first. Only NEW violations are reported; existing ones are tracked but not blocking.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

baseline is a command published in the GitHub repository MilindGaharwar/fettle (2 stars, last pushed 4d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 123 tokens. A static security scan graded it A with 0 findings. It is 88% identical to fettle-baseline, differing in 5 lines, and is treated as a copy.
