Agent Skill

Agency Os skill

agency-osjeremylongshore/tons-of-skills-marketplaceplugins/ai-agency/agency-os/skills/agency-os/SKILL.md

Notion-as-source-of-truth dispatch board for running your work like an AI agency. One Tasks database is the source of truth; tasks flow Suggestion through Discussion, To-Do, In Progress, and Done with subtasks, recurring cadences, dependencies, and template subtrees. Batch execution fans approved To-Do rows out to parallel agents with per-task model selection. Use when capturing chat to Notion, running the To-Do queue, suggesting, approving, or discussing tasks, or coordinating multi-task batches. Trigger with "/agency-os" subcommands or natural-language variants ("add a suggestion: …", "let's discuss X", "run the queue").

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/jeremylongshore/tons-of-skills-marketplace.git /tmp/tons-of-skills-marketplace
mkdir -p ~/.claude/skills
cp -R /tmp/tons-of-skills-marketplace/plugins/ai-agency/agency-os/skills/agency-os ~/.claude/skills/agency-os

For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.

Checks

  • Contains text that matches a prompt-injection pattern. In the skills we checked by hand this was security teaching material or a test fixture; read the file before you install it.
  • Ships scripts the agent can run. Read them before installing.

Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(python3:*), Bash(npx:*), Glob, Grep. The agent can use these without asking while the skill is active.
