What it installs

Skills (7)

  • authoring-github-workflows

    Scaffolds GitHub automation files. Use when the user wants a deterministic GitHub Actions CI/CD workflow (test, build, lint, deploy, release, security), or wants to turn an existing skill into a Copilot custom agent, a GitHub Agentic Workflow (gh-aw), or a CI/CD smart-failure agent. Not for local ev

  • authoring-instructions

    Creates and audits the instruction files agents read: agent rules (rules/*.md), the root AGENTS.md with its thin CLAUDE.md bridge, and event-driven hooks (.apm/hooks/hooks.json plus handler scripts). Use when the user wants to write, check, trim or migrate a rule, AGENTS.md or CLAUDE.md, or to add o

  • authoring-plugins

    Scaffolds and audits whole agent plugins. Use when the user wants to create a new plugin directory (manifest, README, skills folder) or to audit or validate an existing plugin: its structure, .claude-plugin/plugin.json, components, portability and compliance. Also use after a plugin's components cha

  • authoring-skills

    Creates, audits and improves agent skills (SKILL.md folders). Use when the user wants to scaffold a new skill (instructional, executable, or stateful), audit or align an existing skill or skill inventory against authoring standards, add a Docker runtime environment or Azure AI Foundry deployment to

  • authoring-subagents

    Creates and audits sub-agent definitions (agents/*.md): focused system prompt, frontmatter, tool sandbox and trigger examples. Use when the user wants to write, check or fix a sub-agent that needs an isolated context, strict tool bounds or an adversarial persona (reviewer, auditor, red team). Not fo

  • packaging-copilot-cowork-plugins

    Creates, validates and prepares Microsoft 365 Copilot Cowork plugin App Packages containing Agent Skills and optional remote MCP connectors. Use when scaffolding, converting, validating, provisioning, packaging or sharing a Cowork plugin. Not for APM package creation or installation (use packaging-w

  • packaging-with-apm

    Packages, installs and distributes agent extensions with APM (Agent Package Manager). Use when the user wants to create a new APM package, convert or migrate an existing plugin to APM and check it installs cleanly, compile a package into AGENTS.md, CLAUDE.md or GEMINI.md, install, update, pin or rol

Build, launch, grade, and schedule Claude Managed Agents (CMA) in your own Anthropic account — a plugin re-implementation of Anthropic's launch-your-agent reference skill (Apache-2.0; independent, not a fork). Every session starts with a goal (./my-agent/goal.json, opt-in SessionStart hook, driven by /cs-goal); loop_compiler.py compiles it into a bounded grade->iterate loop (max_iterations 1..20), a recurring cron scheduled-deployment loop, or a single-pass interview->stage->launch workflow. 6 skills: orchestrator (context: fork goal router) + interview + stage-launch + grade-iterate + run-without-you + wrap-up. 18 stdlib-only deterministic scaffolders (no network/API calls; live launches emitted as BYOK curl that never prints the key), 4 agents, 8 commands, hooks, 5 references, 4 assets. Validators enforce CMA limits. Distinct from engineering/agent-harness (generic domain loop) and write-a-skill (authors Claude Code skills, not CMAs).
