Anthropic API rate limit handling - retry logic, backoff, throttling for batch workloads against Claude models

Use when building an automated test → issue → fix loop with Claude Code and GitHub issues — overnight auto-fixing, regression loops, self-healing CI.

Use when creating, editing, publishing, or deleting posts on Cyril's Workshop blog or the steponnopets.net devblog.

Use when writing or contributing a boofuzz network-protocol fuzzer in this repo — layout, formatting rules, and reading results.

Use when a task needs real-time control of a connected browser via the Browser Bridge Broker — submit JS jobs over HTTP that browsers eval and return.

Use when training a character LoRA (Chroma/Flux or Pony/SDXL) on a RunPod GPU and wiring it into the ComfyUI + pony_web render stack.

Use when writing a new skill or revising an existing one — format, trigger descriptions, and what content belongs in a skill.

Use when you need to find unused methods in a C# solution, trace who calls a method, assess removal impact before refactoring, or generate call-graph documentation/diagrams for C# code.

Use when querying or writing any RI database — Exportmaster (DBISAM sem01/sem04), PostgreSQL x3rocs, X3/Sage1000 SQL Server, keycloak MySQL, or Parquet. DuckDB is the primary read path.

Use when planning a new parser or lexer for a published language spec, validating parser correctness, or fuzz-testing a parser — build a Prolog DCG grammar companion alongside the hand-written parser.

Use when migrating a project from .NET 8 to .NET 9, or preparing .NET 8 code for that migration with only the .NET 8 SDK available (e.g. Claude for Web).

Use when building, debugging, or deploying a DuckDB loadable extension — version matching, "not a DuckDB extension" errors, install paths, auto-loading.

Use when searching, indexing, bulk-loading, or rebuilding indices on RI's Elasticsearch cluster (locked at 5.2) via ServiceLib.Elasticsearch.

Use when sending email from RI C# services — notifications, daily reports, or log files as attachments.

Use when starting ambiguous or high-stakes work, or when the user says "blind spot pass", "interview me", "what am I missing", or asks for an implementation plan.

Use when writing Flowstone-compatible project or hub notes — small Markdown notes with [[wiki-links]] so the knowledge graph stays connected; never touches repo READMEs.

Gitea issue tracker on dw.ramsden-international.com - the triage/plan/execute plan/fixed label workflow, plus creating, querying and commenting on issues via the REST API

Use when resizing, converting, optimizing, or batch-processing images with ImageMagick — especially when the magick command isn't found on PATH on Windows.

Use when finding dead JS/TS code, tracing callers (call graphs), or analyzing module and circular dependencies in a JS/TS project.

UTF-8 file logging with automatic date-based filenames and thread-safe operations for RocsMiddleware services

Use when working on the Nawin .NET 9 codebase or connecting to 9front/Plan 9 over 9P2000 — file serving, CPU shell, FUSE/ProjFS mounts, auth.

This describes how to create Parquet files in C#, including updating and multi threaded creation

PostgreSQL database operations using PgQuery tool for DDL execution, schema management, and query operations

Use when reading or writing JSON in Python on Windows to avoid CP-1252 mojibake — the convention here is to copy this skill's json_io.py into the project and always open JSON as UTF-8.

Use when a task needs local LLM inference via the on-box Ollama server (Qwen 2.5) instead of a cloud API.

Use when deploying behind the Apache reverse proxy on rivsprod01, writing a ProxyPass config in /etc/apache2/proxy-conf.d/, or fixing 404s under a path prefix.

Use when building a .NET 9 service from RI's shared components (ExportKing, KdbxCredentials, OhSheet, Anthea) deployed as a TinyWeb CGI, or registering a URL on the dw portal page.

Alpine and Debian QEMU VMs for protocol testing, fuzzing, and network experiments

Use when starting or writing Rust projects — and especially this environment's v4l2 video I/O, RGB-to-YUYV conversion, and frame-timing patterns.

Use when asked "why isn't <record> in this query result", to trace a row through joins, or to decompose WHERE/JOIN-heavy SQL into per-step pass/fail attribution — generates ScryQL rules.pl + queries.sql.

Use when uploading/downloading files to RI's SharePoint Online sites, updating Excel tracker cells, or normalizing pasted share links.

Use when asked to make or generate a song on Suno, automate Suno, or fill the suno.com create form programmatically — drives a logged-in browser via the Browser Bridge.

Invoke once per timer tick under /loop dynamic mode — picks the next unblocked task, works it, schedules the next wake-up. Not for cron-style /loop 60s.

Use when GPU services (Ollama, Whisper, ComfyUI/Flux, OCR) contend for VRAM on the RTX 3090 and hit CUDA OOM.

Use when building an elaborate multi-component claude.ai HTML artifact needing state, routing, or shadcn/ui — not for simple single-file artifacts.

Use when transcribing audio to text via the local whisper.cpp server (large-v3, CUDA) — POST an audio file, get JSON back.

Use when building, deploying, or calling Classic SOAP sub-program web services on Sage X3.
