briefd answers "what do I need for this task" instead of re-sending CLAUDE.md every turn.

briefd indexes a git repo of Markdown and exposes one MCP call, compile_bundle, returning a deduplicated bundle under a token budget you set. On its benchmark of 44 documents and 47 tasks, a 2,000-token bundle costs 1,800 tokens and contains the answering section 96% of the time, against 12,869 tokens at 100% for pasting everything and 4,946 tokens at under 50% for a hand-curated file. The benchmark is the author's own but reproducible with make bench.
