Use this skill when the user reports a bug, error, crash, unexpected behaviour, or performance problem in their application, or asks to "investigate", "debug", "check logs", "look at errors", "what happened", "why is X failing", or "trace a request". Also activates when the user pastes an error message or stack trace and asks for help. Also use when the user asks "what is my app doing?", "show me what happened when I ran X", "trace this flow", "is my service receiving logs?", "I'm testing this endpoint — what do I see?", or any exploratory runtime question. Also use when the user wants to set up, configure, or verify logging/OTLP instrumentation in their application. Requires Loggles MCP tools to be connected.
Guides using and contributing to LLMaps: Python library for interactive web maps (MapLibre, single HTML). Use when building maps with llmaps (pip or repo), when editing the llmaps repo, or when the user mentions llmaps, MapLibre, or map generation.

Generate accurate, readable D2 block diagrams for software, research, and system explanations from a text brief. Normalize components and edges, write a canonical .d2 source file, render compact sketch-style SVG and optional PNG artifacts by default, support optional LaTeX equation blocks when the diagram genuinely needs them, keep arrows unlabeled unless a label adds concrete meaning, and emit Telegram file directives when needed.
Use when implementing design documents for pure documentation projects, especially when designs contain code examples that need to be converted to skill documentation
Persistent memory for Claude across conversations. Use when starting any task, before writing or editing code, before making decisions, when user mentions preferences or conventions, when user corrects your work, or when completing a task that overcame challenges. Ensures Claude never repeats mistakes and always applies learned patterns.
Use this when you are working on file operations like reading, writing, scanning, or deleting files. It summarizes the preferred file APIs and patterns used in this repo. It also notes when to use filesystem helpers for directories.
[What this skill does and when to use it]
Verify and install project tooling before feature development. Detects language (Node/TS, Python, Rust, Go), installs linter, formatter, type checker, dead code detection, pre-commit hooks, test framework, and standardized scripts. Idempotent — tracks state in .tooling-state.json. Use when starting a new project, when /develop Phase 4c runs, or when the user says "bootstrap", "setup tooling", "install dev tools", "quality gates".
Use when creating or modifying REST API endpoints (Rails controllers, engine routes, API actions). Requires generating or updating an API Collection file (e.g., Postman Collection v2.1) so the new or changed endpoints can be tested. Trigger words: endpoint, API route, controller action, API collection, request collection. --- # REST API Collection Use this skill when you add or change a REST API endpoint so that a compatible collection file is generated or updated for testing in a modern API client. **Core principle:** Every API surface (Rails app or engine) has a single API collection file that stays in sync with its endpoints. All names, descriptions, and variable labels in the collection must be in **English**. ## Quick Reference | Aspect | Rule | |--------|------| | When | Create or update collection when creating or modifying any REST API endpoint (route + controller action) | | Format | Postman Collection JSON v2.1 (`schema` or `info.schema` references v2.1) is a good default standard. | | Location | One file per app or engine, e.g. `docs/api-collections/<app-or-engine-name>.json` or `spec/fixtures/api-collections/` | | Language | All request names, descriptions, and variable names in the collection in **English** | | Per request | method, URL (with variables for base URL), headers (Content-Type, Authorization if needed), body example when applicable | ## HARD-GATE: Generate on Endpoint Change ``` When you create or modify a REST API endpoint (new or changed route and controller action), you MUST also create or update the corresponding API collection file so the flow can be tested. Do not leave the collection missing or outdated.
Use when planning architectural changes, investigating code existence, consolidating shared modules, or making any declaration about codebase state. Also use when starting any multi-file refactor, cross-sensor integration, or import resolution analysis.
Look up a package's supply-chain risk score, alerts, and version history using attach-guard. Use this when a user asks about a package's safety, or when attach-guard blocks an install and you want to understand why.

Generate or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, or transparent-background cutouts. Use when Codex should create a brand-new image, transform an existing image, or derive visual variants from references, and the output should be a bitmap asset rather than repo-native code or vector. Do not use when the task is better handled by editing existing SVG/vector/code-native assets, extending an established icon or logo system, or building the visual directly in HTML/CSS/canvas.
