Upgrades Python dependencies with automatic breaking change detection.
| Aspect | Details |
|---|---|
| Input | Project path, package manager type |
| Output | Updated requirements.txt/pyproject.toml |
| Supports | pip, poetry, pipenv |
Phases: Pre-flight → Detect Manager → Security Audit → Check Outdated → Apply Upgrades → Verify Installation → Report
| Check | Required | Action if Missing |
|---|---|---|
| requirements.txt OR pyproject.toml OR Pipfile | Yes | Block upgrade |
| Virtual environment active | No | Warn user (risk of system pollution) |
| Git clean state | Yes | Block (need clean baseline for revert) |
Workers assume coordinator (ln-820) already verified git state and created backup.
MANDATORY READ: Load shared/references/git_worktree_fallback.md — use ln-823 row.

| Manager | Command |
|---|---|
| pip | pip-audit --json |

| Priority | Tool | When to Use |
|---|---|---|
| 1 | mcp__context7__query-docs | First choice for library docs |
| 2 | mcp__Ref__ref_search_documentation | Official docs and PyPI |
| 3 | WebSearch | Latest info, community solutions |
| Step | Tool | Parameters |
|---|---|---|
| 1. Find library | mcp__context7__resolve-library-id | libraryName: "pydantic" |
| 2. Query docs | mcp__context7__query-docs | query: "pydantic v1 to v2 migration breaking changes" |
| Action | Tool | Query Example |
|---|---|---|
| Search | mcp__Ref__ref_search_documentation | "python pydantic 2 migration guide" |
| Read | mcp__Ref__ref_read_url | URL from search results |
Use when Context7/Ref return no results:
"<package> python <version> breaking changes migration""<ImportError message> <package> fix"| Check | Command |
|---|---|
| Import test | python -c "import <package>" |
| Tests | pytest or python -m pytest |
| Field | Description |
|---|---|
| project | Project path |
| packageManager | pip, poetry, or pipenv |
| duration | Total time |
| upgrades[] | Applied upgrades |
| verification | PASSED or FAILED |
MANDATORY READ: Load breaking_changes_patterns.md for full patterns.
| Package | Breaking Version | Key Changes |
|---|---|---|
| pydantic | 1 → 2 | V1 compatibility layer needed |
| sqlalchemy | 1 → 2 | Query syntax changes |
| fastapi | 0.99 → 0.100+ | Pydantic v2 required |
Options:
# Upgrade scope
upgradeType: major # major | minor | patch
# Security

| Error | Cause | Solution |
|---|---|---|
| ImportError | Breaking API change | Search Context7/Ref for migration |
| Dependency conflict | Version mismatch | Try pip-compile or poetry lock |

Design, implement, and audit inclusive digital products using WCAG 2.2 Level AA standards. Use this skill to generate semantic ARIA for Web and accessibility traits for Web and Native platforms (iOS/Android).

Whole site or product — a full web accessibility (a11y) audit against WCAG 2.2, following the WCAG-EM methodology. Defines scope, samples representative pages and flows, runs the automated tier (`accessibility-scan`) and the hands-on manual tier (`accessibility-inspect`), and produces one conformance report. Grades each finding by severity and evidence basis, and states per-criterion conformance as pass, fail, or undetermined (needs a human). Use it for 'audit my site for accessibility', 'is this product accessible', 'a11y audit', 'WCAG or Section 508 conformance report', or any multi-page assessment. Assesses; does not fix (use `accessibility-fix`) or diff (use `accessibility-diff`). For a single page use `accessibility-scan`; for hands-on keyboard and screen-reader checks use `accessibility-inspect`.

Regression check — diff a live page's web accessibility (a11y) violations against a baseline. By default it compares your uncommitted changes (stash-based); pass `--branch [<name>]` to compare against a branch. Reports the new WCAG violations introduced, the ones fixed, and the count of pre-existing ones. Use it for 'did my change break accessibility', 'what a11y issues did this PR add', or as a CI gate. For a full scan of one page use `accessibility-scan`; for a whole site use `accessibility-audit`.

Remediation only — repair web accessibility (a11y) violations against WCAG 2.2 with a baseline, edit, and verify loop. Takes a target (URL, files, directory) or a findings worklist from `accessibility-scan`/`accessibility-inspect`/`accessibility-audit`, applies mechanical fixes as given, leaves TODOs for visual or contextual judgment, and verifies by re-running the baseline check. It only fixes. To find issues use `accessibility-scan` (one page, automated), `accessibility-inspect` (one page, manual), or `accessibility-audit` (whole site, WCAG-EM); to check for regressions use `accessibility-diff`. Use it for 'fix the a11y issues in X', 'make this accessible', 'add missing alt text and labels', 'apply these accessibility fixes', 'remediate these violations'.

One page, hands-on manual tier — drive a live page through the web accessibility (a11y) checks a rule engine can't decide: keyboard operation and focus order, screen-reader names, roles and states from the accessibility tree, reflow and zoom, reduced motion, form errors, and target size. Grades each finding by evidence basis (verified / confirm-with-a-human / human-required) and severity, and closes every criterion in a ledger: verified, flagged, not exercised, or N/A. Locates and assesses; does not fix (use `accessibility-fix`). Use it for keyboard testing, focus-order checks, screen-reader or a11y-tree review, reflow and zoom at 200%, or 'is this operable, not just lint-clean'. The automated tier is `accessibility-scan`; `accessibility-audit` runs both across a sampled site.

One page, automated tier — run the web accessibility (a11y) rule engine against a live page and locate every violation it can detect mechanically. Pass a URL, a config target name (e.g. `accesslint:accessibility-scan dev`), or nothing to use the default target from `accesslint.config.json`. Ensures a debuggable Chrome, runs the @accesslint/core engine over CDP, and returns a worklist of live-DOM WCAG 2.2 violations, each grounded to its DOM selector and source `file:line`. Locates; doesn't edit. Use it for 'is this page accessible', 'check a11y on this URL', 'find contrast and alt-text issues', or to verify a UI change. For hands-on keyboard and screen-reader checks use `accessibility-inspect`; for a whole site or product use `accessibility-audit`; to diff against uncommitted changes or a branch use `accessibility-diff`.
