What it does
Bernstein Quality is an agent skill from sipyourdrink-ltd/bernstein. Show quality metrics for Bernstein runs - success rates per model, lint/test pass rates, completion time distributions. Use when the user asks about quality, reliability, which model performs best, or pass rates.
Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/quality.sh`).
It sits in Development, covering Linting and formatting. The repository describes itself as: The open‑source AI Agents Governance & Orchestration framework: write the rules declaratively, Bernstein enforces them and produces the verifiable, replayable record. Free…. The licence is Apache-2.0.
When your agent uses it
- The user asks about quality
- Which model performs best
Example prompts
- “/bernstein-quality”
Requirements
- A Bash shell
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Run scripts/quality.sh metrics for overall quality metrics.
- Run scripts/quality.sh pass-rates for lint/typecheck/test pass rates by model.
- Run scripts/quality.sh times for completion time distributions.
- Present a quality dashboard
- Highlight any models with significantly lower pass rates.
- Recommend model routing adjustments if one model consistently underperforms.
What it can do on your machine
Read from SKILL.md and the folder at commit aee2ea2. 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
Ships 1 file in scripts/ (Shell), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Bernstein Quality loads about 388 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 102 words of instructions outside code blocks.
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); the scripts in this folder are not scanned.

- User asks "how reliable are the agents?" or "which model is best?"
- User wants success rates, pass rates, or completion time stats
- User asks about test failures or lint issues across models
- User says "show me quality metrics"
