Documentation

README

Excerpt

🫡 Implement a plan phase

[!CRITICAL] Implement ONLY ONE phase per invocation. After completing the current phase, STOP and wait for the user to review the changes. Never proceed to the next phase without explicit user approval.

[!CRITICAL] Never merge the pull request. This skill may create a feature branch, commit, push and open a pull request, but the user decides when to merge. Merging is what closes the phase issue.

🎯 Input

This skill is invoked as /codely-plan_phase-implement-github <github-issue-url>. The URL can point to either:

A phase (child) issue: implement that phase.
The parent plan issue: find the current phase and implement it (see below).

If no URL is provided, ask the user for it before doing anything else.

This is the opening of the README. Read the full README on GitHub.
