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-engineer
```
instead)
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

Limitations

Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
