Review guidelines

What to flag:

Check compliance with the Metabase Clojure style guide (included above)
If
```
CLOJURE_STYLE_GUIDE.adoc
```
exists in the working directory, also check compliance with the community Clojure style guide
Flag all style guide violations

What NOT to post:

Do not post comments congratulating someone for trivial changes or for following style guidelines
Do not post comments confirming things "look good" or telling them they did something correctly
Only post comments about style violations or potential issues

Example bad code review comments to avoid:

This TODO comment is properly formatted with author and date - nice work!

Good addition of limit 1 to the query - this makes the test more efficient without changing its behavior.

The kondo ignore comment is appropriately placed here

Test name properly ends with -test as required by the style guide.

Special cases:

Do not post comments about missing parentheses (these will be caught by the linter)

Quick review checklist

Use this to scan through changes efficiently:

Naming

Descriptive names (no
```
tbl
```
,
```
zs'
```
)
Pure functions named as nouns describing their return value
```
kebab-case
```
for all variables and functions
Side-effect functions end with
```
!
```
No namespace-alias repetition in function names

Documentation

Public vars in
```
src
```
or
```
enterprise/backend/src
```
have useful docstrings
Docstrings use Markdown conventions
References use
```
[[other-var]]
```
not backticks

TODO

comments include author and date:

;; TODO (Name 1/1/25) -- description

Code Organization

Everything
```
^:private
```
unless used elsewhere
No
```
declare
```
when avoidable (public functions near end)
Functions under 20 lines when possible
No blank, non-comment lines within definition forms (except pairwise constructs in
```
let
```
/
```
cond
```
)
Lines ≤ 120 characters

Tests

Separate
```
deftest
```
forms for distinct test cases
Pure tests marked
```
^:parallel
```
Test names end in
```
-test
```
or
```
-test-<number>
```

Modules

Correct module patterns (OSS:

metabase.<module>.*

, EE:

metabase-enterprise.<module>.*

)

API endpoints in
```
<module>.api
```
namespaces
Public API in
```
<module>.core
```
with Potemkin
No cheating module linters with
```
:clj-kondo/ignore [:metabase/modules]
```

REST API

Response schemas present (
```
:- <schema>
```
)
Query params use kebab-case, bodies use
```
snake_case
```
Routes use singular nouns (e.g.,
```
/api/dashboard/:id
```
)
```
GET
```
has no side effects (except analytics)
Malli schemas detailed and complete
All new endpoints have tests

MBQL

No raw MBQL manipulation outside
```
lib
```
,
```
lib-be
```
, or
```
query-processor
```
modules
Uses Lib and MBQL 5, not legacy MBQL

Database

Model and table names are singular nouns
Uses
```
t2/select-one-fn
```
instead of selecting full rows for one column
Logic in Toucan methods, not helper functions

Drivers

New multimethods documented in

docs/developers-guide/driver-changelog.md

Passes
```
driver
```
argument to other driver methods (no hardcoded driver names)
Minimal logic in
```
read-column-thunk
```

Miscellaneous

Example data is bird-themed when possible
Kondo linter suppressions use proper format (not
```
#_:clj-kondo/ignore
```
keyword form)

Pattern matching table

Quick scan for common issues:

Pattern	Issue
`calculate-age` , `get-user`	Pure functions should be nouns: `age` , `user`
`update-db` , `save-model`	Missing `!` for side effects: `update-db!` , `save-model!`
`snake_case_var`	Should use kebab-case
Public var without docstring	Add docstring explaining purpose
`;; TODO fix this`	Missing author/date: `;; TODO (Name 1/1/25) -- description`
`(defn foo ...)` in namespace used elsewhere	Should be `(defn ^:private foo ...)`
Function > 20 lines	Consider breaking up into smaller functions
`/api/dashboards/:id`	Use singular: `/api/dashboard/:id`
Query params with `snake_case`	Use kebab-case for query params
New API endpoint without tests	Add tests for the endpoint

Feedback format examples

For style violations:

This pure function should be named as a noun describing its return value. Consider
user
instead of
get-user
.

For missing documentation:

This public var needs a docstring explaining its purpose, inputs, and outputs.

For organization issues:

This function is only used in this namespace, so it should be marked
^:private
.

For API conventions:

Query parameters should use kebab-case. Change
user_id
to
user-id
.
