What it does

Bernstein Cost is an agent skill from sipyourdrink-ltd/bernstein. Show detailed cost breakdown and budget status for the Bernstein orchestrator. Use when the user asks about spending, budget, cost per model, cost per agent, or wants a cost projection.

Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/costs.sh`).

It sits in Agent Workflows. 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 spending
Wants a cost projection

Example prompts

“/bernstein-cost”

Requirements

A Bash shell

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Run scripts/costs.sh to fetch cost data.
Run scripts/costs.sh projection for cost forecast.
Present a clear cost report
If budget warning is active, highlight it prominently.
If over budget, note that Bernstein has paused new task claims.

What it can do on your machine

Read from SKILL.md and the folder at commit cc0c7fc. 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 Cost loads about 332 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 87 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~50
When it runs · the whole SKILL.md, loaded when a task matches: ~332

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.

SKILL.md

The full file from sipyourdrink-ltd/bernstein at commit cc0c7fc, republished under its Apache-2.0 licence (© sipyourdrink-ltd). 87 words, ~332 tokens.
