mthines Bundle Optimize Mock DataOptimizes a directory of structurally-related JSON / JSONL mock fixtures by inferring a shared schema, detecting structural drift between files, normalizing formatting and key order, and optionally shrinking verbose payloads while preserving shape. Use when fixture files have grown inconsistent (mixed tabs / 2-space indent, reordered keys, fields present in some files but missing from others, megabyte-sized payloads), when adding a new mock that must match an existing set, or when preparing fixtures for a storage-cost-sensitive context. Four modes — `analyze` (default, read-only), `normalize` (rewrites files in place), `shrink` (caps verbose string fields), `trim` (reduces array cardinality without touching strings). Triggers on "optimize mock data", "normalize fixtures", "check mock structure", "audit mocks", "shrink test fixtures", "are these mocks consistent", "/optimize-mock-data".

Use this skill whenever the user wants to: break or bypass a system, understand how something really works under the hood, approach a hard problem from first principles, think adversarially about their own design, find the edge cases that break assumptions, do recon/enumeration, or just "think like a hacker". Trigger on phrases like "how would an attacker...", "what's the weakest point", "how does X actually work", "can I bypass...", "CTF", "reverse engineer", "undocumented API", "what assumptions am I making", or any request for lateral / creative / adversarial problem-solving. Also trigger when the user seems stuck in a local optimum and needs a fundamentally different angle of attack.

daedalus Bundle Jsf Av Cpp StandardsReference and apply the Joint Strike Fighter (JSF) Air Vehicle C++ Coding Standards (Doc. No. 2RDU00001 Rev C, "AV Rules") — the Lockheed Martin/MISRA-derived safety-critical C++ standard used in avionics and other high-assurance software. Use this skill whenever the user asks to review, audit, or lint C++ code against the JSF/AV rules or against safety-critical C++ coding standards generally; asks about a specific "AV Rule" by number; wants to write safety-critical, MISRA-style, or DO-178B-adjacent C++ code; asks about coding standards for embedded, avionics, automotive, or other high-integrity C++ systems; or references "JSF", "Air Vehicle coding standards", "2RDU00001", or similar. Also use it to explain the rationale behind a specific rule, find which rule(s) a code snippet violates, or draft a project's own coding standard based on this one.
