ai-driven-development

Query external AI agents (Codex, Gemini, OpenCode, Claude Code headless) in parallel for independent second opinions, code review, bug investigation, and consensus on high-stakes decisions. Agents and models are configurable in config.json. Use for architecture choices, security review, or ambiguous problems where independent perspectives matter. Not for simple questions answerable from docs or the codebase — use web search or repo exploration instead.

8-step disciplined bug-fix protocol that treats every production bug as two failures — the code defect itself and the testing system that allowed it through. Use when fixing a production bug, investigating a regression, writing a post-mortem, or auditing a missed defect. Triggers on "fix this bug", "production bug", "regression test", "post-mortem", "test gap", "why did the tests miss this".

Copy text to clipboard with optional rich formatting. Triggers on "copy to clipboard", "copy that", "pbcopy", "copy formatted", "copy rich text".

Software engineering heuristics from Mark Seemann's book Code That Fits in Your Head (2021). Use when writing new code, reviewing code, refactoring, designing APIs, handling validation and invariants, writing unit tests, debugging defects, performing security review (STRIDE), or setting up a new code base. Covers decomposition (cyclomatic complexity, 80/24 rule, cohesion, fractal architecture), encapsulation (invariants, parse-don't-validate, Postel's law), outside-in TDD (walking skeleton, AAA, triangulation, devil's advocate), API design (affordance, poka-yoke, CQS), git/PR hygiene (50/72 commits, small commits, code review), feature flags, Strangler pattern, bisection debugging, logging with decorators, and STRIDE threat modelling. Not for language-specific syntax, framework tutorials, production incident response, or performance profiling.

Fetch a web page (URL) and return clean Markdown via local trafilatura, with Exa MCP as a fallback for JS-rendered or anti-bot pages. Use when the user asks to read, fetch, scrape, summarize, or quote a URL — prefer this over the built-in WebFetch tool. Don't use for binary files (PDFs, images, archives) or for fetching API/JSON endpoints.
