The merge-base changed after approval.
Reduce DEFAULT_LIMIT from 200 to 50 and PAGE_SIZE from 1000 to 200 so a list call cannot flood an agent's context window. Update every list_* tool description, the sift_mcp playbook, and both shipped skill assets to state the new bounds. Add a test asserting every registered list_* description advertises the starting, maximum, and default limits, so a future bound change cannot silently drift from the documentation agents read.
