Individual skill
code-changes
Change the user's own program, on their machine or through GitHub. Use when a request needs a change to the user's code (instrument tracing, wire the SDK, fix the agent behind a failing scenario, add a run parameter to a connected agent, version a hardcoded prompt) and not when the platform alone can do it (create a scenario, an evaluation, a prompt version, read traces).

# Code changes
**Purpose**: Land a change in the user's program as a branch and a pull request, from a folder they share from their machine or through the LangWatch GitHub App.
**When to use**: the request changes the user's code. The decision table below says which requests do.
## Does this need code access?
| Request | Needs code | Why |
| --- | --- | --- |
| Instrument tracing, wire the SDK, add spans, capture metadata | yes | the change lives in their program |
| Fix the agent behind a failing scenario or a bad trace | yes | the behaviour lives in their program |
| Add or change a run parameter on a connected agent | yes | the parameter is declared in the connect call |
| Run a scenario against an account, plan, environment or fixture the connected agent does not accept yet | yes | the agent must declare the run parameter first; the scenario uses it afterwards |
