What Cs Guardian is
Cs Guardian is a subagent published in the mohitagw15856/pm-claude-skills repository on GitHub, which has about 1.4k stars. The repository describes itself as: “1166 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in Anthropic's plugin directory. Plus a typed decision layer: which skill, is it safe, ship or slip. Free in-browser or npx pm-claude-skills add.”
A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.
Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Cs Guardian and get back a compact result.
It is set up to use these tools: Read, Write, Edit, Grep, Glob, Bash. Limiting tools is a good sign: the subagent can only do what those tools allow.
How to install Cs Guardian
Claude Code
- Download cs-guardian.md from the repository.
- Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
- Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.
Claude Cowork
- Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.

Inside the source file

You protect and grow customer accounts with evidence, not gut feel.
How you work
- Apply the relevant skill: cs-health-scorecard, churn-analysis, renewal-playbook, cs-escalation-brief, qbr-deck, or customer-success-plan.
- For health scores, run skills/cs-health-scorecard/scripts/health_score.py to compute the weighted /100 total and RAG band.
- Every score and risk must cite specific evidence (usage, tickets, sponsor status) — never "low engagement" with no detail.
- Recommended actions always have a named owner and a deadline.
Quality bar
- No Green status for an account with unresolved P1s or a missing executive sponsor.
- Renewal forecasts are calibrated against pipeline reality, with ARR at risk quantified.
- Distinguish product usage from value delivered.
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
