8-8: Empty value – confirm intention
BROKEN_VAR=sets the variable to an empty string. If this is deliberate, add a comment clarifying; otherwise provide a real value or remove it.
14-14: Reference to undefined variable
${UNDEFINED_HOST}will resolve to an empty string. Either defineUNDEFINED_HOSTabove or remove the interpolation.

🛠️ Refactor suggestion
Duplicate keys – only the last one wins
DUPLICATE_KEY is declared twice; most loaders keep the second value and silently drop the first, masking errors. Delete the duplicate or rename the variable.
🤖 Prompt for AI Agents
In test.env around lines 9 to 10, the environment variable DUPLICATE_KEY is
declared twice, which causes the first declaration to be ignored and can lead to
confusion or errors. Remove one of the duplicate declarations or rename one of
the keys to ensure each environment variable is unique and avoid silent
overwriting.

There was a problem hiding this comment.
Invalid UTF-8 escape sequences
\x80\x81\x82 are outside printable ASCII and will be loaded literally, potentially breaking systems that assume UTF-8. Encode them as base64 or remove the variable.
🤖 Prompt for AI Agents
In test.env at line 20, the variable INVALID_UTF8 contains invalid UTF-8 escape
sequences \x80\x81\x82 which may cause issues. To fix this, either remove the
INVALID_UTF8 variable entirely or replace its value with a base64-encoded string
representing the intended bytes to ensure safe loading and compatibility with
UTF-8 systems.

Never commit real secrets to VCS
SECRET_KEY contains a live-looking credential in plain text. Move it to a secure secret store or at least to an untracked .env.local, and replace this file with a redacted placeholder.
🤖 Prompt for AI Agents
In test.env at line 3, the SECRET_KEY is set to a real-looking secret which
should not be committed to version control. Replace the current SECRET_KEY value
with a placeholder value that does not expose any real credentials, and move the
actual secret to a secure secret store or an untracked file like .env.local to
keep it out of the repository.

In test.env at line 19, the value for BAD_QUOTES is missing a closing single
quote, causing an unterminated string. Fix this by adding the closing single
quote at the end of the value or replace the single quotes with double quotes to
properly terminate the string.

In test.env at line 6, the PASSWORD value contains unescaped double quotes
causing unterminated string issues. Fix this by either wrapping the entire
password value in single quotes or escaping the inner double quotes properly to
ensure the string is correctly parsed.

Missing “=” delimiter will break every .env parser
DATABASE_URL is missing the required =. Nothing after the key is parsed, so the variable is effectively undefined.

parsing by .env parsers.

Trim spaces around “=” to preserve the value
Most parsers treat the leading space as part of the key and the trailing space as part of the value (" someapikey"). Remove the padding.

In test.env around lines 4 to 5, the environment variable names are invalid
because they start with digits or contain hyphens, which is not allowed. Rename
the variables so that they start with a letter or underscore and only contain
uppercase letters, digits, or underscores. For example, change "123TOKEN" to a
valid name like "TOKEN123" and "API-KEY" to "API_KEY".

In test.env at lines 12 to 13, the environment variable MULTILINE_VAR is split
across two lines without proper quoting, which breaks the file parsing. To fix
this, rewrite the value as a single line string enclosed in quotes and use \n to
represent the line break inside the quotes, ensuring the entire value is
contained on one line.
