DATABASE_URL postgres://user:pass@localhost:5432/dbname

Choose a reason for hiding this comment

The reason will be displayed to describe this comment to others. Learn more.

⚠️ Potential issue

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.

-DATABASE_URL postgres://user:pass@localhost:5432/dbname
+DATABASE_URL=postgres://user:pass@localhost:5432/dbname
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

DATABASE_URL postgres://user:pass@localhost:5432/dbname
DATABASE_URL=postgres://user:pass@localhost:5432/dbname
🤖 Prompt for AI Agents 
In test.env at line 1, the environment variable assignment for DATABASE_URL is
missing the '=' delimiter. Add an '=' between the key and the value so the line
reads DATABASE_URL=postgres://user:pass@localhost:5432/dbname to ensure proper
parsing by .env parsers.

🛠️ Refactor suggestion

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.

+API_KEY=someapikey

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
API_KEY = someapikey
API_KEY=someapikey
🤖 Prompt for AI Agents 
In test.env at line 2, remove any spaces around the equals sign in the
assignment to API_KEY so that it reads exactly "API_KEY=someapikey" without
spaces before or after the "=" to ensure the value is parsed correctly without
leading or trailing spaces.

SECRET_KEY = this is a bad secret
Copy link

The reason will be displayed to describe this comment to others. Learn more.

⚠️ Potential issue

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.

The reason will be displayed to describe this comment to others. Learn more.

⚠️ Potential issue

Invalid variable names (cannot start with digits or contain “-”)

.env keys should match [A-Z_][A-Z0-9_]*.

Suggested change

# Replace the invalid lines in test.env:
-TOKEN=abcdefg
-API-KEY=invalidformat
+TOKEN_123=abcdefg
+API_KEY_INVALIDFORMAT=invalidformat
🤖 Prompt for AI Agents 
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".

PASSWORD="my"pass"word"
Copy link

Choose a reason for hiding this comment

The reason will be displayed to describe this comment to others. Learn more.

⚠️ Potential issue

Broken quoting creates an unterminated value

Interleaving " characters splits the value mid-string. Wrap the whole value in single quotes or escape inner quotes.

+PASSWORD='my"pass"word'
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
PASSWORD="my"pass"word"
PASSWORD='my"pass"word'
🤖 Prompt for AI Agents 
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.

REDIS_URL=redis://localhost:6379 # trailing comment
Copy link

Choose a reason for hiding this comment

The reason will be displayed to describe this comment to others. Learn more.

🛠️ Refactor suggestion

Inline comments are parsed as part of the value

Most dotenv loaders do not support # comments after the value. If you need a comment, put it on its own line.

-REDIS_URL=redis://localhost:6379 # trailing comment
+# Comment: local redis
+REDIS_URL=redis://localhost:6379
🤖 Prompt for AI Agents 
In test.env at line 7, the inline comment after the REDIS_URL value is being
parsed as part of the value, which is not supported by most dotenv loaders.
Remove the trailing comment from the same line and place the comment on a
separate line above or below the REDIS_URL entry to ensure correct parsing.

🛠️ 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.

The reason will be displayed to describe this comment to others. Learn more.

⚠️ Potential issue

Multiline values are not supported without explicit quoting

Lines 12-13 split a value over two lines, corrupting every subsequent variable. Use \n inside quotes instead.

-MULTILINE_VAR=This is a
-bad idea
+MULTILINE_VAR="This is a\nbad idea"
🤖 Prompt for AI Agents 
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.

⚠️ Potential issue

Leading space and missing “=”

SPACED_VAR has a leading space, and MISSING_EQUALS_SIGN lacks an equals sign entirely.

MISSING_EQUALS_SIGN=somevalue
🤖 Prompt for AI Agents 
In test.env at lines 17 to 18, remove the leading space before SPACED_VAR and
add an equals sign for MISSING_EQUALS_SIGN to correctly assign its value. The
corrected lines should have no leading spaces and use the format VARIABLE=VALUE.

⚠️ Potential issue

Unterminated single-quoted string

Add the closing quote or switch to double quotes.

BAD_QUOTES='unfinished'
🤖 Prompt for AI Agents 
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.

INVALID_UTF8=\x80\x81\x82
Copy link

Choose a reason for hiding this comment

The reason will be displayed to describe this comment to others. Learn more.

⚠️ Potential issue

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.
