bernstein-planCreate and manage multi-step execution plans in Bernstein. An agent skill from sipyourdrink-ltd/bernstein.
Bernstein Plan is an agent skill from sipyourdrink-ltd/bernstein. Create and manage multi-step execution plans in Bernstein. Plans decompose complex goals into stages with dependencies. Use when the user wants to plan a complex feature, break down a large task, or review an execution plan before agents start working.
Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/plan.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.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit aee2ea2. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Bernstein Plan loads about 649 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 208 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.
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.

Bernstein Plan fits situations like: the user wants to plan a complex feature; break down a large task; review an execution plan before agents start working.
Run `npx skills add sipyourdrink-ltd/bernstein --skill bernstein-plan -a claude-code`. Or copy the skill folder (packages/cursor-plugin/skills/bernstein-plan in sipyourdrink-ltd/bernstein) into .claude/skills/bernstein-plan in your project. Claude Code loads it when a task matches its description.
Run `npx skills add sipyourdrink-ltd/bernstein --skill bernstein-plan -a codex`. Or copy the skill folder (packages/cursor-plugin/skills/bernstein-plan in sipyourdrink-ltd/bernstein) into .agents/skills/bernstein-plan in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add sipyourdrink-ltd/bernstein --skill bernstein-plan -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/bernstein-plan, .gemini/skills/bernstein-plan, .github/skills/bernstein-plan and .opencode/skills/bernstein-plan in your project.
Going by SKILL.md and its folder, Bernstein Plan needs a shell for the scripts in its folder. Our summary lists: A Bash shell.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Bernstein Plan is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 649 tokens (SKILL.md is roughly 2.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Bernstein Plan: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 297k stars).
