- Move references/mdr-status-codes.md into the skill's own references/
so the file lives with the only skill that consumes it.
- Add references/performance-diagnosis-playbook.md: decision tree for
which signal to investigate first, per-channel diagnostic patterns,
cross-skill handoff matrix, and Sent-support escalation criteria.
- Add scripts/analyze_mdr_funnel.py (Python 3.11+, stdlib only): parses
CSV or JSON MDR exports, computes per-stage funnel counts and drop-off
percentages across QUEUED -> ROUTED -> SENT -> DELIVERED -> READ, exits
non-zero when any stage exceeds --threshold (default 20%).
- Add scripts/fixtures/{good,bad}.json: 100-message synthetic exports for
smoke-testing the analyzer (good is healthy, bad has a >50% drop at
SENT -> DELIVERED).
- Update SKILL.md with a Bundled-references-and-scripts table and a
pointer to the top-level Sent glossary; namespace Related-Skills
refs with sent-skills:.

Per-skill content is identical to PR #9. - Move references/mdr-status-codes.md → skills/messaging-performance-analyzer/references/ - Add performance-diagnosis-playbook.md - Add analyze_mdr_funnel.py (stdlib only) + good/bad fixtures - Add glossary cross-link to Related skills - Replace aspirational script names in bundled-resources table with the shipped one Closes #9 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
