FAST code generation via Z.ai glm-4.6 model. Use for rapid test generation, boilerplate code, repetitive patterns, and bulk file creation. Ideal when speed matters more than nuance. Do NOT use for complex architectural decisions or security-critical code.
Coordinates FAST code generation via Z.ai glm-4.6 with CodeSearch pattern learning. Use when agents need rapid test generation, bulk code creation, or repetitive boilerplate. Tracks successful prompts for continuous improvement. Ideal for high-volume, low-complexity code tasks.
Use when facing decisions with multiple legitimate perspectives and inherent tensions. Invoke when stakeholders have competing priorities (growth vs. sustainability, speed vs. quality, innovation vs. risk), need to pressure-test ideas from different angles before committing, exploring tradeoffs between incompatible values, synthesizing conflicting expert opinions into coherent strategy, or surfacing assumptions that single-viewpoint analysis would miss.
- [Purpose](#purpose)
Perform post-merge integration tasks after a code PR is successfully merged. This skill completes the development cycle by moving approved specs from `docs/changes/` to `docs/specs/`, updating the ret
Specifies bugs, upgrades, refactors, and behavioral changes as explicit deltas against existing feature specifications, preserving original intent while defining what changes, what remains unchanged, and how correctness is verified.
Classify a change set as behavior vs structure, then recommend the correct PR label (change:behavior or change:structure) and the appropriate local/CI checks. Use when the user asks whether a change is a behavior change or a structure change, what label to apply, or how CI/testing should differ based on change type.
Update app ChangeLog entries under apps/*/ChangeLog and keep app version metadata in sync. Use when updating app versions or recording app-level changes; touches apps/*/ChangeLog and apps/*/src/*.app.src.
