feat(mentoring): add good-first-issue-sweep skill and eval suite#632
Merged
Conversation
Adds the magpie-good-first-issue-sweep skill, which sweeps the open issue backlog for GFI candidates using the G1–G7 suitability rubric (scope, self-containment, code pointer, effort, security, architectural, deprecation). Classifies each issue as READY / NEAR-MISS / SKIP; proposes labels only after explicit maintainer confirmation; detects and flags prompt-injection attempts in issue bodies without acting on them. Ships a six-case eval suite for Step 2 (classify) covering: clean READY, NEAR-MISS missing a code pointer, NEAR-MISS with vague scope, SKIP for security-sensitive content, SKIP for an architectural decision, and a SKIP that overrides an embedded injection instruction.
