OpenTelemetry Weaver registry authoring, codegen, and CI enforcement. Use when adopting Weaver, authoring or reviewing a registry (manifest, attributes, metrics, spans, events), writing Jinja2 templates against the resolved schema, migrating hand-maintained telemetry constants, wiring `weaver registry check`/`generate`/`diff` into CI, or choosing a Weaver version for a semantic-conventions release.

Build safe, version-pinned telemetrygen commands for synthetic OTLP traces, metrics, and logs. Use for “send sample traces to this collector,” “load-test an OTLP endpoint,” “generate traffic to verify a processor, OTTL transform, or tail sampling,” and “produce test data for dashboards.” Also use when choosing telemetrygen transport, TLS, attributes, counts, duration, or rate. Not for application SDK instrumentation or production collection that does not use telemetrygen.

OpenTelemetry in Ruby — SDK setup, manual tracing, experimental metrics and logs, Bundler integration, contrib instrumentation for Rails/Rack/Sinatra/Sidekiq and other gems, propagation, performance, and upgrades. Use when adding, reviewing, configuring, or troubleshooting OpenTelemetry in a Ruby or Rails service. Triggers on "setup otel in ruby", "ruby telemetry", "Rails OpenTelemetry", "OpenTelemetry::SDK.configure", "opentelemetry-instrumentation-all", "Ruby tracing", "Rack otel", "Sidekiq otel", or any Ruby-related OTel question.

Assess OpenTelemetry package and Collector upgrades across ecosystems. Use when choosing or validating API, SDK, instrumentation, exporter, Collector distribution, component, image, chart, Operator, OCB build, or configuration versions, including compatibility, required changes, telemetry and runtime behavior, and rollout risk.

Draft cold emails, warm intro blurbs, follow-ups, update emails, and investor communications for fundraising. Use when the user wants outreach to angels, VCs, strategic investors, or accelerators and needs concise, personalized, investor-facing messaging.

Diagnose interface errors, drops, CRCs, duplex mismatches, flapping, speed negotiation issues, and counter trends on routers, switches, and Linux hosts. Use when an interface shows errors, drops, CRCs, flapping, or a duplex or speed mismatch.

Run the conversational ECC setup wizard inside the current harness: inventory the install, collect scope (user/project/local) and hook mode (off/minimal/standard/strict) in Claude Code, use Codex's native plugin lifecycle, or install the project surface under ./.kimi-code, then preview, apply, and verify. Use when installing, updating, reconfiguring, or repairing an ECC installation, changing hook profiles, or moving ECC between install scopes.

Manage truckload, LTL, and intermodal carrier portfolios: sourcing and FMCSA vetting, freight rate and fuel-surcharge negotiation, RFPs and routing guides, carrier scorecards, allocation, and renewals. Use when onboarding carriers, running freight RFPs, negotiating rates, evaluating carrier performance, reallocating freight, or building freight strategy.

Convert 'make it faster' requests into a bounded measured optimization loop — baseline first, generate one-hypothesis variants, benchmark each against a correctness gate, and promote the fastest safe variant with reproducible commands. Use when asked to speed something up, try many variants, run recursive optimization, benchmark latency/throughput/cost, or pick the best implementation by repeated measured tests.

Draft cold emails, warm intro blurbs, follow-ups, update emails, and investor communications for fundraising. Use when the user wants outreach to angels, VCs, strategic investors, or accelerators and needs concise, personalized, investor-facing messaging.

Fetches a YouTube video's transcript as plain text (optional [mm:ss] timestamps) with a stdlib-only Python script that works from cloud IPs where yt-dlp and youtube-transcript-api are blocked. Use before summarising or quoting a video; triggers on a youtube.com / youtu.be link plus "transcript", "summarise this video", or "/youtube-transcript".

Records reviewable browser videos — a cursor, click ring, and step captions drawn on the page, dead waits cut, H.264 mp4 out, a per-step timings file and contact sheet beside it — for a scripted scene list, a test runner's raw Playwright video, or a Chrome tab driven by another tool (recorded over the DevTools protocol). Triggers on "record this interaction", "screen recording", "make a video of", "/screencast".

Use when reviewing code changes before committing or merging — staged diffs, branch diffs, or PR readiness checks. Triggers: 'review my code', 'check these changes', 'review this branch', 'give feedback on my diff', 'is this PR ready?'. Not for implementing features, running test suites, formatting-only passes, or building understanding of a change (use teach-me).

Design and build a responsive frontend website or accessible landing page for a small business or creator from the first brief. Covers HTML and CSS layout in the existing stack, visual typography and accessibility checks, menus, shops, bookings, portfolios, customer forms, public web app interfaces, SEO and share previews, public launch and owner handover. Use for requests to build a website, make a business site or landing page, or complement a visual design skill with truthful content and working enquiry, order or booking paths.

Writes the UI-layer tests of a use case (UC-XXX) for an Angular client with Vitest and Angular's own testing idioms: TestBed component tests for the routed page, HttpTestingController for the API boundary, DI overrides for non-HTTP services, and plain service tests — in UC-XXX-<slug>.spec.ts files with a describe('UC-XXX: …') block. Use when the user asks to "write frontend tests", "test the Angular component", "write a Vitest test", "unit test an Angular page", "test the UI of UC-001", or mentions TestBed, ComponentFixture, or HttpTestingController. Normally run by /use-case-test as the UI test layer of a project whose docs/architecture/stack.md names Angular; it can also be run directly. Browser tests against the running application are /playwright-e2e-test.

Import data into the AWS data lake from S3 files, local uploads, JDBC databases (Oracle, SQL Server, PostgreSQL, MySQL, RDS, Aurora), Amazon Redshift, Snowflake, BigQuery, DynamoDB, or existing Glue catalog tables (migration). Default target is S3 Tables; standard Iceberg on a general purpose bucket is supported where S3 Tables is not adopted. Handles one-time loads, recurring pipelines, migrations. Triggers on: import data, load data, ingest, sync database, migrate table, move data to AWS, set up pipeline, ETL, pull from Snowflake, query BigQuery into S3, export DynamoDB, CTAS, convert to Iceberg. Do NOT use for setting up or troubleshooting Glue connections (use connecting-to-data-source), creating empty tables (use creating-data-lake-table), running queries (use querying-data-lake), finding tables by fuzzy name (use finding-data-lake-assets), catalog audit (use exploring-data-catalog), or SaaS platforms like Salesforce, ServiceNow, SAP, MongoDB, Kafka.

Create managed Iceberg tables using Amazon S3 Tables (s3tables API namespace) with automatic compaction and snapshot management. Sets up table bucket, namespace, table, schema, Glue catalog registration, partitioning, IAM access control. Triggers on: create table, data lake table, analytics table, structured data storage, S3 Tables, Iceberg, Athena table, partitioning strategy, access permissions. Do NOT use for: importing files (use ingesting-into-data-lake), vector storage (use storing-and-querying-vectors), querying existing tables (use querying-data-lake), or locating existing table (use finding-data-lake-assets).
