Use when doing any parser work — adding new Oracle text patterns, verb forms, phrase helpers, target patterns, subject handling, effect chain composition, fixing Unimplemented fallbacks, or understanding the parser architecture. This is the SINGLE SOURCE OF TRUTH for all oracle parser knowledge. Covers the nom…
Fast-iteration loop for quick parser wins — surface near-miss cards via parser-gap-analyzer's typed category classifier, edit in batches, compile once per batch (not per card), defer the full gate (fmt/clippy/test-all/coverage/semantic-audit) to session end. Companion to unlock-set; use this when the fix is "add a…
Use when asked to handle, harden, or shepherd one or more external contributor PRs. Checks out PRs in a worktree or main workspace, updates them against origin/main, resolves review comments, performs architecture-focused implementation review, decides whether fixes are inline or require engine-implementer review…
Use to run a continuous review sweep over open contributor PRs in phase.rs. The skill is a thin orchestration layer over scripts/prreview.py: discover candidates, detect stale reviews/follow-ups, dispatch review-impl for PRs that need judgment, and delegate authorized merge handling to pr-contribution-handler.
Use when retraining AI evaluation weights from 17Lands replay data, adding new training datasets, updating learned weight values in phase-ai Rust code, or running CMA-ES optimization for AI profiles and evaluation parameters.
Review phase.rs engine, parser, AI, frontend, or rules implementation plans before code is written. Use when Codex needs an architectural gate for plans involving parser changes, engine mechanics, MTG Comprehensive Rules behavior, new variants, targeting, replacement effects, stack/casting flow, AI policy, or frontend…
Review an implementation in scope, such as an uncommitted diff, a just-finished agent change, a commit, or named files, for missing or wrong behavior in phase.rs. Use when Codex needs a findings-only architecture and correctness review across engine, parser, frontend, multiplayer, AI, deck, build, or release changes.
Use when shipping local commits to main via the merge queue. Creates an isolated worktree based on origin/main, cherry-picks the named commits into a fresh branch, pushes with --no-verify, opens a PR with gh pr create --fill, and enqueues with gh pr merge --auto. Outbound counterpart to pr-contribution-handler. Use…
Unlock the majority of a Magic set's unsupported cards by clustering missing parser/engine primitives, briefing the engine-implementer skill tier-by-tier, and committing between clusters. Use when the user asks to "unlock the [SET] cards", "improve coverage for [SET]", or requests highest-ROI coverage work on a…
Use when writing, modifying, or reviewing CR (Comprehensive Rules) annotations in engine code — any time a // CR or /// CR comment is added, changed, or audited. Ensures every CR number is verified against docs/MagicCompRules.txt before it enters the codebase.
Instructions for phase-rs/phase, covering claude.md, project overview, design principles — read this first, when in doubt and agent team orchestration standards.
