56 portable AI-agent skills for the deliverables knowledge work actually ships — ADRs, design docs, PRDs, runbooks, decks, threat models, adversarial code review — plus 3 reviewer subagents and 6 role packs. Agent Skills open standard; installs into Claude Code, Cursor, Codex, Copilot, Kiro, Antigravity.
Agent Claude Code
Cost-aware dispatcher for skilldrop skills (Claude Code implementation of the provider-neutral routing spec in model-routing.json). Given a skill name + the task input, looks up the skill's abstract tier, applies cheap no-LLM heuristics (input size, ambiguity, user override), resolves the tier to a concrete model via…
Agent
Craft-and-maintainability reviewer of just-written code. Finds what the next engineer will hate — bad names, tangled structure, duplication, needless complexity, leaky abstractions, dead code, and unreadable control flow. Does NOT hunt for bugs (that's the devils-advocate agent). Delegate to it when code works but you…
Agent
Adversarial reviewer of just-written code and tests. Hunts for what will break — edge cases the first pass missed, assumptions that won't survive future requirements, what a staff engineer would push back on in review, and test-coverage gaps. Delegate to it right after a feature is declared "done", before opening a PR…
Agent
Security reviewer of just-written code and its dependencies. Hunts for exploitable weaknesses in the change — missing authz, injection, secret exposure, SSRF, unsafe deserialization, path traversal, weak crypto, and risky new dependencies. Does NOT hunt general bugs (that's devils-advocate) or model a design's threat…
