What does Accesslint Diff do?

Accesslint Diff is a command-line argument parser that processes Git branch specifications and repository URLs for accessibility linting workflows. It strips `--branch ` flags to enable branch-specific analysis, defaulting to a preconfigured branch if none is provided.

When should I use Accesslint Diff?

Use Accesslint Diff when you need to run accessibility audits against specific Git branches in CI/CD pipelines or automated testing environments, particularly for comparing accessibility issues between feature branches and main branches or integrating accessibility checks into pull request workflows.

What input format does Accesslint Diff expect?

Users provide command-line arguments in the format `$ARGUMENTS`, which may optionally include the `--branch ` flag followed by a repository URL. The branch flag is optional; if omitted, the tool operates in default mode.

What does Accesslint Diff output?

The tool outputs a parsed configuration that identifies whether branch mode is active, which branch to target (either the specified or default branch), and the cleaned URL with branch flags stripped away, ready for downstream accessibility linting processes.

Overview

Accesslint Diff

Accesslint Diff parses command-line arguments to identify branch mode, extract branch names, and isolate repository URLs. It strips the `--branch <name>` flag when present, defaults to a preconfigured branch if the flag has no value, and passes the remainder as the target URL for accessibility linting operations. Use Accesslint Diff when building accessibility linting workflows that need to target specific Git branches based on runtime arguments. It fits CI/CD pipelines, pre-commit hooks, and manual audits where developers specify which branch to analyze or rely on a default branch fallback.

What it does

Accesslint Diff is a command-line argument parser designed for accessibility linting workflows. It extracts branch names and repository URLs from user input, routing requests to either branch-specific analysis or default-branch scanning based on the presence and value of the --branch flag.

When to use - and when NOT to

Use Accesslint Diff when you need to parse command-line arguments for accessibility linting tools that support branch-based analysis. It is ideal for CI/CD pipelines, pre-commit hooks, or manual audits where developers specify which branch to lint. Use it when your workflow requires flexible branch targeting - either explicit branch names or fallback to a default branch.

Do not use this skill if your accessibility tooling does not support branch-based analysis or if you only ever lint a single, fixed branch. It is also not appropriate for workflows that require parsing complex multi-flag command structures beyond the --branch <name> pattern and URL extraction.

Inputs and outputs

Users provide command-line arguments in the form of $ARGUMENTS, which may include the --branch <name> flag followed by a URL. The branch flag is optional; if present without a value, the parser defaults to a preconfigured default branch.

The skill outputs a parsed structure identifying whether branch mode is active, the target branch name (explicit or default), and the extracted URL. The remainder of the argument string after stripping the branch flag becomes the URL for the accessibility linting operation.

Who it's for

Accesslint Diff is built for developers and DevOps engineers who integrate accessibility linting into version-controlled workflows. It serves teams that need to audit accessibility issues on feature branches before merging, QA engineers running branch-specific accessibility reports, and automation engineers building CI/CD pipelines that conditionally lint different branches based on runtime parameters.

Source README

Parse $ARGUMENTS: strip --branch <name> if present → branch mode. If --branch has no value, use the default branch above. Remainder is the URL.
