Changelog

1.0.0 — 2026-07-08

Semantic search

Hybrid dense (ibm-granite/granite-embedding-english-r2, local and overridable) + BM25 retrieval, weighted by codebase size/documentation characteristics.
Dual-vector indexing: a body-stripped "purpose" vector (signature + docstring) alongside the full-body vector, closing the embedding-dilution gap where a symbol's own doc paraphrase of a query fails to surface it in the dense pool.
Symbol graph with call edges, import chains, and HTTP route extraction (Flask/FastAPI/Express/Spring); vectr_locate (5 fallback strategies) and vectr_trace for callers/callees.
AST-aware chunking across 7 languages (Python, JavaScript, TypeScript, Go, Rust, Java, Zig) plus C and C++; all other file types fall back to overlapping window chunking.

Working memory

Five note kinds (directive, task, gotcha, finding, reference), each with distinct injection semantics — directives fire unconditionally, gotchas resurface when their anchored file is touched.
Two-tier vectr_recall: a token-bounded index by default, full note bodies on request (note_id= or detail='full').
Session-start boot injection of directives and high-priority tasks, recency-ordered.
vectr_snapshot / vectr_snapshot_list to checkpoint and browse working-memory state.
Multi-agent shared memory: workspace-scoped notes act as a shared bus for orchestrator/subagent handoff, with explicit (never inferred) agent attribution on vectr_remember.

Context relief

vectr_fetch: deterministic, byte-verbatim re-fetch of a previously-seen chunk by id, with a truncation warning when the index's own storage cap capped the original chunk.
vectr_evict_hint, with recency-ordered re-fetch ids, so the calling model knows what it can safely drop from context.
Remember nudges with dual-gate escalation (chunk count and token count) so a light reminder scales into a stronger banner only once both thresholds are crossed.

Editor integration

Zero-config MCP setup: auto-written config for Claude Code, Cursor, and VS Code / GitHub Copilot; manual config documented for Windsurf, Cline, and Continue.
Auto-generated CLAUDE.md guidance template describing the tool surface and when to use each tool.
Claude Code session hooks (SessionStart, UserPromptSubmit, PreToolUse, PreCompact) for automatic recall injection, with an injection-observability status line.

Ops

--memory-only daemon mode: working memory + hooks without code indexing or the file watcher, for actively-edited or performance-sensitive projects.
File watcher burst governor and RSS self-limit to bound resource use during large or rapid file-change bursts.
Multi-workspace instance registry (vectr status --all, vectr stop --all) and per-workspace status surfaces.
