Self-verification — spawn a fresh-context subagent to independently check that finished work actually satisfies the original request. Re-derives the task from a briefing you write (poisson subagents start with a blank conversation, not a copy of this one),…
Universal code-quality principles for any language or codebase — simplicity, clarity, and minimalism in the spirit of the suckless manifesto, Linus Torvalds' "good taste", a hacker's distrust of complexity, and the conviction that one mind can understand the…
General code review process — scan lenses (correctness, performance, edge cases, test coverage, security, API design, boundary/type cleanliness, orchestration/atomicity, ambitious simplification with a file-size ceiling and spaghetti-growth check, comment…
Convene a council of legendary engineers — spawned as parallel subagent personas — to review code, critique an architecture, or pressure-test an idea, then synthesize their verdicts into one ranked answer. Each legend carries a distinct, durable engineering…
Workflow for opening a pull request — picking a conventional-commit title, writing a tight What / Why / Testing description, and self-reviewing the diff before pushing. Language-agnostic and minimal in the spirit of suckless and Torvalds' "show me the code".…
Scout the blast radius of a change before or after writing it — name the shared seam it touches, enumerate from the code every mode, flag, header, and consumer already flowing through that seam, then classify each as works-unchanged / wired /…
Set up an isolated podman sandbox for a work session — mount the right directory (workdir, or a fresh git worktree when parallel branches could conflict) from the start, do all bash/build/test work through the container, edit files with the normal host-path…
Author a new SKILL.md — as a builtin shipped in the px binary (internal/skills/builtin/<name>/SKILL.md, embedded via go:embed, no other code change needed) or as a user skill under ~/.poisson/skills/<name>/SKILL.md (picked up live, /reload, overrides a…
