Rule Quality Evaluator
Core principle: A rule that cannot be violated cannot be followed. Most instruction files fail not because they're too short or too long, but because they're full of unfalsifiable guidance, redundant noise, and implicit knowledge that never made it to paper. This skill scores rules against seven measurable properties, identifies structural weaknesses, and optionally verifies behavior with live coding tasks.
Two-Phase Overview
- Phase 1 — Static Critic (always run): Read the rules, score each against the Seven Properties, detect structural issues, produce a scorecard. No agent execution required.
- Phase 2 — Behavioral Test (opt-in): Generate coding tasks that touch the rules, derive testable assertions, hand off to context-eval, synthesize the combined report.
Interview-only fallback: If no instruction file is accessible (chat-only context, no filesystem), ask the user to paste the rules directly. Flag at the end: "I can't verify codebase alignment — code pattern checks will need manual verification."
Phase 1 — Static Critic
Step 1: Ingest
Read the instruction file(s). Detect the format (Markdown prose, structured rules list, YAML front matter, fenced sections). Parse into individual rules — one rule = one discrete behavioral instruction. When in doubt, split on bullet points, numbered items, or paragraph breaks that each start an imperative.

4summarizer
Apply this skill whenever the user asks to summarize, condense, distill, or compress any content — a document, article, meeting notes, conversation, codebase, book, research paper, video transcript, or any other source material. Triggers on phrases like 'summarize this', 'give me the TL;DR', 'condense this', 'what are the key points?', 'distill this down', 'brief me on this', 'what's the gist?', 'BLUF this', 'executive summary', 'compress this for me', or any request to reduce content while preserving its essential value. Also trigger when the user pastes a long text and implicitly wants it shortened, when they share a link and ask 'what does this say?', or when they ask for meeting notes or action items from a transcript. This skill does NOT apply to 'explain X to me' (use topic-explainer) or 'write a summary section for my doc' (use technical-writing). This skill is for when source material exists and needs to be compressed.
3inversion-premortem
Apply inversion and pre-mortem thinking whenever the user asks to evaluate a plan, strategy, architecture, feature, or decision before execution — or when they want to stress-test something that already exists. Triggers on phrases like "is this a good idea?", "what could go wrong?", "review this plan", "should we do this?", "are we missing anything?", "stress-test this", "what are the risks?", or any request to validate a decision or design. Use this skill proactively — if the user is about to commit to something, this skill should be consulted even if they don't ask for it explicitly.
3llms-txt-generator
Generate llms.txt-style context documents — token-budgeted, section-per-concept Markdown optimized for LLM and RAG consumption. Use this skill whenever someone asks to generate an llms.txt, create LLM-friendly documentation, produce a context document for a library or codebase, build a RAG-ready reference, make docs 'agent-readable', create a developer quick-reference, or says anything like 'generate context for X', 'make an llms.txt for this repo', 'create a reference doc for NotebookLM', 'turn these docs into something an LLM can use', 'context document', 'developer cheatsheet from docs'. Also trigger when someone provides a GitHub repo URL and asks for documentation synthesis, or when working inside a codebase and asked to produce a self-contained reference of how it works. This is the context engineer's doc generation tool — it turns sprawling documentation into precise, structured, token-efficient context.

3probabilistic-thinking
Apply probabilistic and Bayesian thinking whenever the user needs to reason under uncertainty, compare risks, prioritize between options, update beliefs based on new evidence, or make decisions without complete information. Triggers on phrases like "what are the odds?", "how likely is this?", "should I be worried about X?", "which risk is bigger?", "does this data change anything?", "is this a signal or noise?", "what's the probability?", "how confident are we?", or any situation where decisions are being made based on incomplete or ambiguous evidence. Also trigger when someone is treating uncertain outcomes as certainties, or when probability language is being used loosely ("probably", "unlikely", "very likely") without quantification. Don't leave uncertainty unexamined.
