What problem does it solve? Triage teams need consistent, defensible effort estimates for incoming issues, but manual sizing is subjective and slow. This Skill analyzes an issue's title, body, and code exploration output to produce a structured SMALL, MEDIUM, or LARGE effort estimate with reasoning. ## Core Features & Use Cases - Structured Effort Classification: Outputs a JSON object with an effort_estimate (SMALL, MEDIUM, or LARGE) and detailed effort_reasoning. - Domain-Specific Sizing Rules: Applies calibrated criteria for the Gemini CLI codebase, covering Ink UI components, node-pty and signal handling, MCP transport, A2A protocol, and cross-package refactors. - Reproducibility Guardrails: Automatically excludes intermittent, platform-specific, or hard-to-reproduce bugs from the SMALL category due to testing overhead. - Use Case: During automated issue triage, feed an issue report plus discovered source files into this Skill to receive a consistent effort label that informs prioritization and sprint planning. ## Quick Start Estimate the implementation effort for this issue using the attached code exploration output and return the JSON result.
