# Hook: PostToolUse (matcher: Bash)

#
|

# Fires AFTER a Bash tool call completes. When a git commit/merge/rebase
|
|
# just succeeded, surfaces 1-3 relevant memories from the changed files
|
|
# and prompts Claude to ask the user if this change should be stored as
|
|
# a learning.
|
|
#
|
|
# Input: JSON on stdin with tool_name, tool_input, tool_response
|
|
# Output: Context injected into Claude's next response (exit 0)
|
|
#
|
|
# This implements Spec #28 — interactive pre-commit memory check.
