This skill should be used when a full sprint or phase retrospective needs facilitation, when the improvement backlog needs management, or when retrospective action items from a prior sprint need follow-up. This is the primary retrospective skill — sprint-facilitation references it for deep retrospective guidance. Triggers when a user asks for a retrospective format, wants to track improvement actions, or is running a phase retrospective as a gate artefact.
The retrospective is the primary continuous improvement mechanism in the lifecycle. It operates at two levels: sprint retrospective (end of each sprint) and phase retrospective (post-gate, before the next phase starts). When well-facilitated, retrospectives produce a concrete improvement backlog that reduces friction sprint over sprint. This skill provides facilitation formats, action item tracking, and quality indicators for both levels. Note: skills/sprint-facilitation/SKILL.md references this skill for deep retrospective guidance — these skills must be used together.
Identify whether this is a sprint retrospective or a phase retrospective:
Structure the session using the retrospective schema in schemas/retrospective.schema.json. For phase retrospectives, extend with phase-level sections covering contract adherence, RACI effectiveness, and governance quality.
Before the session:
Open every retrospective by reviewing what was committed in the last one:
This prevents retrospectives from becoming performative — teams that never follow up on actions lose trust in the format.
For sprint retrospectives, use the Start/Stop/Continue format (default):
