Pre-merge finalization checklist for a change. Use when: wrapping up a feature or fix before opening or updating a PR, preparing to hand work back to the user for commit, or when /finalize-pr is invoked. Bumps the package version when warranted, refreshes README benchmark stats and prose to match behavior changes, runs an editor-lens pass over the diff to trim comment debt, runs the full test suite and flake8, and surfaces a final summary. Does NOT commit, push, or open PRs — those remain the user's responsibility.
Write tests for bocpy Behavior-Oriented Concurrency code. Use when: writing pytest tests for @when behaviors, Cown scheduling, send/receive messaging, cown grouping, chained behaviors, exception propagation. Covers parameter-count rules, module-level class requirements, and the send/receive assertion pattern.
Follow bocpy commenting and documentation conventions. Use when: adding comments to C or Python files, writing docstrings, documenting structs or classes, adding Doxygen doc-comments, using Sphinx param style, suppressing linter warnings with noqa, or following flake8 style rules (Q000, D205, D209, N802).
Multi-perspective planning with rebuttal rounds and adversarial review loop. Use when: planning complex changes, designing architecture, evaluating implementation strategies, drafting implementation plans, or when /plan is invoked. Spawns three planner subagents, runs rebuttals on disagreements, synthesizes their outputs, then iteratively hardens the plan through an adversarial review loop until it passes scrutiny. All intermediate artifacts are persisted to .copilot/ so the process can be restarted from any step.
Think in Behavior-Oriented Concurrency, not threads-and-locks. Use when: writing or reviewing any bocpy code (library, examples, tests), about to reach for time.sleep / threading.Event / atomic counters / polling loops / wait_for_* helpers, designing how a downstream behavior observes an upstream one, scheduling work to run after the next worker is free, or building loop / tail-recursion patterns. Catches the reflex to apply classical synchronization to a problem that wants a cown.
