Use when designing security architecture, conducting penetration tests, implementing cryptography, or performing security audits.

Expert guide for building Emacs transient menus (keyboard-driven UI like Magit). Use when implementing or debugging transient-define-prefix, transient-define-suffix, or transient-define-infix commands.

Guidelines for optimizing Claude rulesets and instruction files (CLAUDE.md, settings.json) using context efficiency principles. Includes strategies for skill extraction, progressive disclosure, token savings calculation, and deduplication. Manually invoke when optimizing rulesets, reducing context size, extracting content to skills, or improving ruleset organization.

Protocol fuzzer script development using boofuzz framework. Use when creating network protocol fuzzers, defining protocol PDUs (Protocol Data Units), writing mutation-based fuzzing scripts, or contributing to the boofuzz project. Covers binary protocol definitions, session management, crash detection, and reporting findings.

LLM function calling and tool use patterns. Use when enabling LLMs to call external tools, defining tool schemas, implementing tool execution loops, or getting structured output from LLMs.

Maintain "just enough" context across work sessions using CURRENT.md, STATUS.md, and LESSONS.md files. Activate when tasks take >15 minutes, touch 3+ files, interruptions likely, or scope uncertain. Includes /snapshot and /pickup commands for saving and resuming work. ADHD-friendly, token-efficient approach.
