What it does

Ibm A11y Route Scan is an agent skill from langflow-ai/langflow. Batch-scan Langflow frontend routes for accessibility issues using the Python IBM Equal Access scanner (scripts/a11y/a11yscan.py) and produce JSON/Markdown/HTML reports. Scans the default-loaded state of each route only (use explicit state files for modals). Use when asked to scan one or more routes, produce an accessibility report for pages, or batch-check static routes. Reports findings only — does not fix code, run Playwright/axe tests, or perform a formal Level 1 audit; see ibm-a11y-testing-guide…

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Accessibility. It works with Python and Playwright. The repository describes itself as: Langflow is a powerful tool for building and deploying AI-powered agents and workflows. The licence is MIT.

When your agent uses it

  • Asked to scan one
  • Produce an accessibility report for pages
  • Batch-check static routes

Example prompts

  • “/ibm-a11y-route-scan”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 504c02f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ibm A11y Route Scan loads about 1.6k tokens when it runs. Until then it costs about 147 tokens; SKILL.md has 436 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~147
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Batch-scan Langflow frontend routes for accessibility issues using the Python IBM Equal Access scanner (scripts/a11y/a11y_scan.py) and produce JSON/Markdown/HTML reports. Scans the default-loaded state of each route only (use explicit state files for modals). Use when asked to scan one or more routes, produce an accessibility report for pages, or batch-check static routes. Reports findings only — does not fix code, run Playwright/axe tests, or perform a formal Level 1 audit; see ibm-a11y-testing-guide, ibm-a11y-level1-audit, and ibm-a11y-pr-remediation for those.

IBM Route Scanner

Use this skill when asked to scan Langflow frontend pages for accessibility issues with the local Python scanner. This skill only reports — it does not modify code. For test-writing guidance, formal audits, or PR-wide fixes, see ibm-a11y-testing-guide, ibm-a11y-level1-audit, and ibm-a11y-pr-remediation.

Scanner

Use the Python script:

bash
uv run python scripts/a11y/a11y_scan.py \
  --url http://localhost:3000 \
  --routes-file scripts/a11y/a11y_routes.json \
  --route-group static \
  --out /tmp/langflow-a11y-report.json \
  --markdown /tmp/langflow-a11y-report.md \
  --html /tmp/langflow-a11y-report.html \
  --timeout-ms 45000

Script options:

  • --url: base app URL, usually http://localhost:3000.
  • --routes-file: route manifest JSON file. Prefer scripts/a11y/a11y_routes.json.
  • --route-group: manifest group to scan. Default: static.
  • --routes: comma-separated route paths to scan.
  • --route: one route path; can be repeated instead of --routes.
  • --levels: comma-separated issue levels. Default: violation.
  • --out: JSON report path.
  • --markdown: optional Markdown report path.
  • --html: optional self-contained HTML report path.
  • --timeout-ms: per-route timeout.
  • --quiet-ms: network quiet window before scanning. Default: 1000.
  • --states-file: JSON file with explicit modal/state actions.
  • --headed: show browser while scanning.

Route Selection

Use scripts/a11y/a11y_routes.json as the source of truth for route selection.

The normal CI/local batch is the manifest static group. Prefer that unless the user asks for custom, dynamic, or gated routes.

Common manifest-backed command:

bash
uv run python scripts/a11y/a11y_scan.py \
  --url http://localhost:3000 \
  --routes-file scripts/a11y/a11y_routes.json \
  --route-group static \
  --out /tmp/langflow-a11y-static.json \
  --markdown /tmp/langflow-a11y-static.md \
  --html /tmp/langflow-a11y-static.html

Dynamic routes need real IDs before scanning:

  • /flow/:id/
  • /flow/:id/view
  • /playground/:id/
  • /assets/knowledge-bases/:sourceId/chunks

For dynamic routes, get IDs from the loaded app, API responses, or existing test data before replacing placeholders.

Examples

Scan one route:

bash
uv run python scripts/a11y/a11y_scan.py \
  --url http://localhost:3000 \
  --route /flows \
  --out /tmp/langflow-a11y-flows.json

Scan multiple routes:

bash
uv run python scripts/a11y/a11y_scan.py \
  --url http://localhost:3000 \
  --routes-file scripts/a11y/a11y_routes.json \
  --route-group static \
  --out /tmp/langflow-a11y-report.json \
  --markdown /tmp/langflow-a11y-report.md \
  --html /tmp/langflow-a11y-report.html

Scan more than violations:

bash
uv run python scripts/a11y/a11y_scan.py \
  --url http://localhost:3000 \
  --routes-file scripts/a11y/a11y_routes.json \
  --route-group static \
  --levels violation,potentialviolation,recommendation \
  --out /tmp/langflow-a11y-expanded.json

Scan route plus modal states:

bash
uv run python scripts/a11y/a11y_scan.py \
  --url http://localhost:3000 \
  --states-file /tmp/langflow-a11y-states.json \
  --out /tmp/langflow-a11y-modal-report.json \
  --markdown /tmp/langflow-a11y-modal-report.md \
  --html /tmp/langflow-a11y-modal-report.html \
  --timeout-ms 45000

State file shape:

json
[
  {
    "route": "/settings/global-variables",
    "states": [
      {
        "name": "new-global-variable-modal",
        "open": [
          { "click": "[data-testid='api-key-button-store']" },
          { "waitFor": "[role='dialog']" }
        ],
        "close": [
          { "press": "Escape" },
          { "waitForHidden": "[role='dialog']" }
        ]
      }
    ]
  }
]

Supported state actions:

  • { "click": "<css selector>" }
  • { "clickText": "<visible text>" }
  • { "clickRole": { "role": "button", "name": "Create" } }
  • { "fill": { "selector": "<css selector>", "value": "text" } }
  • { "press": "Escape" }
  • { "press": { "selector": "<css selector>", "key": "Enter" } }
  • { "waitFor": "<css selector>" }
  • { "waitForHidden": "<css selector>" }
  • { "waitForText": "<visible text>" }
  • { "wait": 500 }
  • { "scroll": { "selector": "<css selector>", "to": "bottom" } } — to is top or bottom; use "by": <pixels> for a relative scroll, and omit selector to scroll the page. Needed for virtualised grids whose tabbable rows only disappear after scrolling.

Report

The scanner always writes JSON. It can also write Markdown and HTML for presentation.

Use JSON for exact data. Use Markdown for PR comments or issues. Use HTML when the user wants a browsable report.

Summarize:

  • report path
  • Markdown/HTML report paths, when generated
  • total issue count
  • per-route issue count
  • per-route API request count
  • per-route request failure count
  • top rule IDs

Use report fields directly:

  • totalIssues
  • results[].route
  • results[].state
  • results[].phase
  • results[].apiRequests
  • results[].requestFailures
  • results[].diagnostics
  • results[].issues[].ruleId

Rules

  • Use only scanner output for findings.
  • Do not invent route names. Read routes.tsx.
  • Do not auto-click arbitrary buttons to find modals. Use explicit state actions.
  • Avoid destructive modal actions unless the user explicitly asks and data is safe.
  • If a route has zero API requests, mention that scan quality may be limited.
  • This skill reports only; do not edit files. If the user also wants fixes applied, hand off to ibm-a11y-pr-remediation or ibm-a11y-level1-audit.
