Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 88 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.00556 |
| Opus 5 | $0.00020 | $0.00278 |
| Sonnet 5 | $0.00008 | $0.00111 |
| Haiku 4.5 | $0.00004 | $0.00056 |
Grade A, and why
rudder-environment-check 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 12d ago.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

RudderStack Environment Check
Quick diagnostic that checks all RudderStack tool prerequisites and provides actionable guidance.
When to Use
- Before starting with RudderStack workflows
- When troubleshooting "command not found" errors
- To verify your development environment is ready
Check Process
Run these checks in sequence:
1. Check rudder-cli
# Check if installed
which rudder-cli
# If installed, check authentication
rudder-cli workspace info
2. Check Terraform (if using terraform workflows)
# Check if installed
which terraform
# If installed, check version
terraform version
# Check if provider is configured (run in project directory)
terraform providers
3. Check MCP Server Connectivity
# Check if hosted MCP server is reachable
curl -s -o /dev/null -w "%{http_code}" https://mcp.rudderstack.com/health

| MCP unreachable | Run /rudder-mcp-setup or check network connectivity |
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.

rudder-environment-check is a skill published in the GitHub repository rudderlabs/rudder-agent-skills (18 stars, last pushed 7d ago), licensed MIT.
