execute-phase

Implement one phase of a feature (default), or a small feature / a fix (--fix) by its SPEC's ## Phases ledger — one phase per invocation, the final phase is always Hardening & PR (the close-out); legacy SPECs without ## Phases run end-to-end in a single pass. Enforces branch safety, issue policy, the project's verification gate, and per-phase doc discipline. On Claude Code and want hand-tuned per-skill model/effort tiers? Install the #claude branch instead (npx skills add gtrabanco/agentic-workflow#claude) — see the README. This branch is model-agnostic: the skill inherits whatever model and effort your agent session is already using. Triggers: "execute phase P1 of NN", "implement the NN feature", "build NN from its spec", "execute-phase NN P2", "execute-phase --fix".
