Manifest Setup
Follow these steps in order. Do not skip ahead.
Use this skill when
- User wants to set up observability or telemetry for their agent
- User wants to connect their agent to Manifest for monitoring
- User needs to configure a Manifest API key or custom endpoint
- User is troubleshooting Manifest plugin connection issues
- User wants to verify the Manifest plugin is running
Do not use this skill when
- User needs general observability design (use
observability-engineerinstead) - User wants to build custom dashboards or alerting rules
- User is not using the Manifest platform
Instructions
Step 1 — Stop the gateway
Stop the gateway first to avoid hot-reload issues during configuration.
claude gateway stop
Step 2 — Install the plugin
claude plugins install manifest
If it fails, check that the CLI is installed and available in the PATH.
Step 3 — Get an API key
Ask the user:
To connect your agent, you need a Manifest API key. Here's how to get one:
- Go to https://app.manifest.build and create an account (or sign in)
- Once logged in, click "Connect Agent" to create a new agent
- Copy the API key that starts with
mnfst_- Paste it here
Wait for a key starting with mnfst_. If the key doesn't match, tell the user the format looks incorrect and ask them to try again.
Step 4 — Configure the plugin
claude config set plugins.entries.manifest.config.apiKey "USER_API_KEY"
Replace USER_API_KEY with the actual key the user provided.
Ask the user if they have a custom endpoint. If not, the default (https://app.manifest.build/api/v1/otlp) is used automatically. If they do:
claude config set plugins.entries.manifest.config.endpoint "USER_ENDPOINT"
Step 5 — Start the gateway
claude gateway install
Step 6 — Verify
Wait 3 seconds for the gateway to fully start, then check the logs:
grep "manifest" ~/.claude/logs/gateway.log | tail -5
Look for:
[manifest] Observability pipeline active
If it appears, tell the user setup is complete. If not, check the error messages and troubleshoot.
Safety
- Never log or echo the API key in plain text after configuration
- Verify the key format (
mnfst_prefix) before writing to config
Troubleshooting
| Error | Fix |
|---|---|
| Missing apiKey | Re-run step 4 |
| Invalid apiKey format | The key must start with mnfst_ |
| Connection refused | The endpoint is unreachable. Check the URL or ask if they self-host |
| Duplicate OTel registration | Disable the conflicting built-in plugin: claude plugins disable diagnostics-otel |
Examples
Example 1: Basic setup
Use @manifest to set up observability for my agent.
Example 2: Custom endpoint
Use @manifest to connect my agent to my self-hosted Manifest instance at https://manifest.internal.company.com/api/v1/otlp
Best Practices
- Always stop the gateway before making configuration changes
- The default endpoint works for most users — only change it if self-hosting
- API keys always start with
mnfst_— any other format is invalid - Check gateway logs first when debugging any plugin issue
