manager

A planning skill for coordinating several AI coding agents. It studies the codebase, breaks a larger goal into smaller tasks with acceptance criteria, sends those tasks to a task server, and checks completion signals.

In plain words
What is it for?
It is for planning backend, frontend, testing, security, DevOps, documentation, architecture, and other software tasks that can be assigned to separate agents.
Why use it?
It removes the need to divide complex work manually and gives each agent a defined responsibility. This makes parallel development easier to organize and review.

Token cost

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.

Security

Grade A, and why

manager scanned grade A with 1 finding 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 yesterday.

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.

What it actually says

Manager Skill

You lead a team of AI coding agents. Decompose the goal into tasks, create them on the task server, and ensure quality.

Responsibilities

  1. Analyze - read the codebase to understand current state.
  2. Plan - break the goal into specific, actionable tasks with clear acceptance criteria.
  3. Create tasks - POST each task to the task server API.
  4. Verify - include completion signals so the janitor can verify work.

Available roles for tasks

backend, frontend, qa, security, devops, docs, architect, reviewer, ml-engineer, retrieval, prompt-engineer, visionary, analyst, resolver, ci-fixer.

Priority / scope / complexity

  • Priority: 1 = critical, 2 = normal, 3 = nice-to-have.
  • Scope: small (<30 min), medium (30-120 min), large (2-8 h).
  • Complexity: low, medium, high.

When done planning

Mark your own task complete with the first-class CLI - it reads your token and the server port itself, so there is no auth header or JSON body to hand-quote:

bernstein task complete {YOUR_TASK_ID} --summary "Created N tasks to achieve goal: ..."

Then exit.

Call load_skill(name="manager", reference="task-api.md") for the full task-creation curl syntax (completion signals, owned_files, API base), or reference="planning-rules.md" for how to size tasks and avoid file-ownership collisions.

Files

What ships with it

2 files 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.

Changes

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.

manager is a skill published in the GitHub repository sipyourdrink-ltd/bernstein (1,038 stars, last pushed today), licensed Apache-2.0. It adds 14 tokens to every session and 416 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
