Documentation

README

Excerpt

Ensure the handler and tests for $ARGUMENTS provide comprehensive coverage.

1. Gather Documentation

Find documentation for the tool (need at least one source):

tldr:

ls ~/source/tldr/pages/*/$ARGUMENTS*.md
cat ~/source/tldr/pages/*/$ARGUMENTS.md

Local CLI:

$ARGUMENTS --help
man $ARGUMENTS

Stop if neither source exists.

2. Explore Subcommands

For tools with subcommands, recursively explore:

$ARGUMENTS <subcommand> --help
$ARGUMENTS help <subcommand>

Build a mental model of:

All subcommands and their actions
Which operations are read-only (safe) vs mutate state (unsafe)
Global flags that affect parsing
Edge cases

3. Review Existing Tests

This is the opening of the README. Read the full README on GitHub.
