# X_SLICE_POLICY_INCOMPLETE

## Means

a generator needs an export the slice policy.ts does not declare

## Typical cause

`x g action` or `x g mutator` was pointed with `--feature` at a slice whose hand-written `policy.ts` does not export the names the generated file imports (`can<Feature>Write`, and for an action `<feature>Tag`). Refused before anything is written, because the generated file would not compile. A barrel or a nested destructuring the scan cannot read is never refused

## Fix

add the export lines the thrown `fix:` spells out for the slice — `export const can<Feature>Write = can('<feature>:write');` and, for an action, `export const <feature>Tag = tag('<feature>');` — to the slice's `policy.ts`, then run the generator again
