codedbpro — daemon-backed read/search/edit for agents

A persistent daemon over MCP: eleven code tools, a symbol index, and shell-free writes.

Three things earn its place, and none of them is raw speed. A git grep across a mid-size repo runs in tens of milliseconds — the same order as an MCP round-trip — so "it's faster" is not the argument, and neither is "fewer tokens" against a disciplined grep … | head:

1. Writes fail closed. expected, if_revision and lines_removed turn a silently-wrong write into an error instead of a corrupted file.
2. Output is bounded. limit, max_per_file and the 256 KiB response ceiling make it hard to burn your whole context on one careless call. The win is that the worst case is capped.
3. Content travels as JSON. Curly quotes, non-ASCII, backticks and $ are safe — this replaces python/perl heredoc surgery and its classic traps.

Fewer ways to be badly wrong, not fewer milliseconds.
