Bernstein is an open-source governance layer for AI agents that applies written policies, schedules agent work deterministically, controls approvals, and records verifiable execution history. It is used to coordinate CLI coding agents and other agent workloads, including parallel runs and offline review, while the catalogue entries provide its agent workflows and controls.
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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 15 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.00400 |
| Opus 5.5 | $0.00019 | $0.00160 |
| Sonnet 5.5 | $0.00009 | $0.00080 |
| Haiku 4.5 | $0.00005 | $0.00040 |
Grade A, and why
bernstein-create-task 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 1mo 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.
What it actually says
Create Bernstein Task
Create a new task in the Bernstein orchestrator and have it picked up by an agent.
When to Use
- User says "create a task for..." or "add this to bernstein"
- User wants to delegate a coding task to an agent
- User describes a bug fix, feature, or refactor that should be orchestrated
- User says "have an agent do this" or "queue this up"
Instructions
-
Ask the user (if not already clear) for:
- Title: short description of the task
- Role: one of
backend,frontend,qa,security,devops,docs(default:backend) - Priority: 0 (urgent) to 3 (low) (default: 1)
- Scope:
tiny,small,medium,large(default:small)
-
Run
scripts/create-task.shwith the task details:scripts/create-task.sh "Fix the auth middleware to handle expired tokens" backend 1 small -
Show the created task ID and confirm it's queued:
Task TASK-042 created (role=backend, priority=1) An agent will pick it up shortly. -
If the user wants to track it, suggest using
/bernstein-status.
Tips
- For complex tasks, suggest breaking them into smaller subtasks
- For risky changes, add
--require-reviewflag - High-priority (0) tasks get picked up immediately
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

bernstein-create-task is a skill published in the GitHub repository sipyourdrink-ltd/bernstein (1,384 stars, last pushed today), licensed Apache-2.0. It adds 47 tokens to every session and 400 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

ara-research-manager
Records research provenance as a post-task epilogue, scanning conversation history at the end of a coding or research session to extract decisions, experiments, dead ends, claims, heuristics, and pivots, and writing them into the ara/ directory with user-vs-AI provenance tags. Use as a session epilogue — never during…
