What it does
Bernstein Agents is an agent skill from sipyourdrink-ltd/bernstein. Manage Bernstein agents - list active agents, inspect their output, kill stalled agents, or stream live logs. Use when the user asks about agents, wants to see what an agent is doing, or needs to kill one.
Its SKILL.md is about 410 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/agents.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 agents
- Wants to see what an agent is doing
- Needs to kill one
Example prompts
- “/bernstein-agents”
Requirements
- A Bash shell
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Run scripts/agents.sh list to get all active agents.
- Present them clearly
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 Agents loads about 408 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 152 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.

Instructions
List agents
- Run
scripts/agents.sh listto get all active agents. - Present them clearly:
## Active Agents (3)
| Agent | Role | Model | Status | Task | Runtime | Cost |
|-------|------|-------|--------|------|---------|------|
| ses-a1b2 | backend | claude-sonnet-4 | alive | TASK-042: Fix auth | 4m 12s | $0.32 |
| ses-c3d4 | qa | gpt-4.1 | alive | TASK-043: Write tests | 2m 45s | $0.18 |
| ses-e5f6 | frontend | claude-sonnet-4 | stalled | TASK-044: Update UI | 8m 03s | $0.51 |Inspect agent
- To see what an agent is doing:
scripts/agents.sh logs <session_id> - Show the last ~20 lines of output.
Kill agent
- To kill a stalled or misbehaving agent:
scripts/agents.sh kill <session_id> - Confirm: "Agent ses-e5f6 terminated. Task TASK-044 returned to open queue."
Stall detection
- If any agent shows
stalledstatus, proactively suggest killing it. - An agent is stalled if it hasn't sent a heartbeat in >60 seconds.
