Configures structured JSON logging for .NET and Python projects.
| Aspect | Details |
|---|---|
| Input | Context Store from ln-770 |
| Output | Logging configuration files |
| Stacks | .NET (Serilog), Python (structlog) |
Accept Context Store from coordinator.
Required Context:
STACK: .NET or PythonFRAMEWORK: ASP.NET Core or FastAPIFRAMEWORK_VERSION: Version numberPROJECT_ROOT: Project directory pathENVIRONMENT: Development or ProductionValidation:
STACK not provided, detect from project filesUse MCP tools to get up-to-date documentation.
For .NET (Serilog):
MCP ref: "Serilog ASP.NET Core structured logging configuration"
Context7: /serilog/serilog-aspnetcore
For Python (structlog):
MCP ref: "structlog Python structured logging configuration"
Context7: /hynek/structlog
Key Patterns to Research:
Ask user for configuration preferences.
| Option | When to Use |
|---|---|
| JSON (Recommended for Production) | Machine-readable, log aggregation systems |
| Pretty/Colored (Recommended for Development) | Human-readable, local debugging |
| Field | Description | Default |
|---|---|---|
correlationId | Request tracking across services | ✓ Yes |
userId | Authenticated user identifier | ✓ Yes |
requestPath | HTTP request path | ✓ Yes |
responseTime | Request duration in ms | ✓ Yes |
machineName | Server hostname | Optional |
threadId | Thread identifier | Optional |
| Sink | Use Case |
|---|---|
| Console | Always enabled |
| File | Local persistence, log rotation |
| Seq | Structured log server |
| Elasticsearch | Log aggregation at scale |
| Level | Development | Production |
|---|---|---|
| Default | Debug | Information |
| Microsoft.* | Information | Warning |
| System.* | Information | Warning |
| Application | Debug | Information |
Generate files based on stack and decisions.
| File | Purpose |
|---|---|
Extensions/LoggingExtensions.cs | Service registration |
appsettings.json (update) | Serilog configuration |
appsettings.Development.json (update) | Dev overrides |

Validation Steps:
Check imports: Ensure all packages are available
dotnet list package | grep Serilogpip list | grep structlogSyntax check:
dotnet build --no-restorepython -m py_compile core/logging_config.pyTest log output:
Expected Log Format:

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`.
