Selection Rules

```
skills/bootstrap-existing-agent-with-prefactor-cli/SKILL.md
```
first.
If the request is about adding telemetry to an existing agent without rewriting business logic, load
```
skills/instrument-existing-agent-with-prefactor-sdk/SKILL.md
```
.
If the request is about creating a custom provider adapter with
```
@prefactor/core
```
, load
```
skills/create-provider-package-with-core/SKILL.md
```
.

Default Workflow

When instrumenting an existing agent, default to this order:

Run

skills/bootstrap-existing-agent-with-prefactor-cli/SKILL.md

to set up resources (

environment

,

agent

,

agent_instance

).

Install required Prefactor npm package(s) via the project's package manager.
Choose the matching adapter package if available (
```
@prefactor/langchain
```
,
```
@prefactor/ai
```
,
```
@prefactor/openclaw
```
).
For adapter-style instrumentation (
```
@prefactor/langchain
```
or
```
@prefactor/ai
```
), keep
```
init
```
,
```
withSpan
```
, and
```
shutdown
```
imports from that same adapter package (or pass an explicit tracer when using core
```
withSpan
```
).

If no matching adapter package exists, use

skills/create-provider-package-with-core/SKILL.md

.

Instrument the existing agent with

skills/instrument-existing-agent-with-prefactor-sdk/SKILL.md
