sgrep
Local semantic and hybrid search for codebases and coding-agent history.
Find implementation by intent, then recover the decisions and fixes that led
to it across Claude Code, Codex, Cursor, OpenCode, and Pi sessions.

Agent skill
Why sgrep?
- Search code by meaning instead of guessing identifiers.
- Search prior agent sessions without reopening transcripts one by one.
- Keep source, conversations, models, and indexes on your machine.
- Give coding agents compact file-and-line results instead of large context dumps.
sgrep "where do we validate authentication tokens"
sgrep conv "why did we change the authentication cache key"
Install
brew tap XiaoConstantine/tap
brew install sgrep
# Download the local embedding model and verify llama.cpp.
sgrep setup
See the installation guide
for curl, Go, source builds, and sqlite-vec.
Search a Codebase
cd your-repository
sgrep index .
sgrep "database connection error handling" # balanced, the default
sgrep --profile fast "request routing" # lowest latency
sgrep --profile quality "JWT validation middleware" # optional ColBERT reranking
| Profile | Pipeline | Use it for |
|---|
fast | Semantic | Quick exploration |
balanced | Semantic + BM25 | Recommended everyday profile; default |
quality | Semantic + BM25 + ColBERT | Optional reranking experiments |

Search Agent Conversations
sgrep conv index
sgrep conv "embedding server ownership bug"
sgrep conv "session compaction" --agent codex --since 7d
sgrep conv resume <session_id>
Conversation search supports Claude Code, Codex CLI, Cursor, OpenCode, and Pi,
with semantic, hybrid, and exact retrieval.

Built for Coding Agents
sgrep complements structural and exact search:
| Tool | Finds | Example |
|---|
sgrep | Intent | sgrep "authentication logic" |
ast-grep | Structure | sg -p '$fn($args)' |
ripgrep | Exact text | rg "JWT_SECRET" |
Install the shared agent skill:
npx skills add XiaoConstantine/sgrep --skill sgrep -g
Claude Code users can also install automatic project indexing and watch hooks:

Architecture
The managed local llama.cpp service is shared, while code and conversation
indexes retain separate retrieval controls. The editable diagram source is at
docs/static/architecture.tldr.

Final Pooled Local Benchmark
In the final controlled local-only comparison, sgrep balanced is the
strongest overall local quality-latency tradeoff and the strongest normalized
implementation-code retriever by point estimate. It is not universally best,
and the bootstrap confidence intervals overlap competing tools.
| Evaluation track | Point-estimate result |
|---|
| Normalized implementation code | sgrep balanced: MRR 0.792, NDCG@10 0.589, R@10 0.413 at 54.4ms median |
| Normalized all files | osgrep wins MRR (0.867); sgrep balanced/quality win NDCG@10 and R@10 (0.607 / 0.340) |
| Native product output | osgrep wins MRR (0.858) and ChunkHound wins R@10 (0.236); sgrep balanced's small NDCG@10 lead is pool-sensitive |
The benchmark used 20 queries, model-judged pooled qrels, sgrep source
19ebec1, and the pinned dspy-go corpus at 87cb50f. Query-bootstrap 95%
confidence intervals overlap, so these are point-estimate verdicts rather than
significance claims. balanced is recommended over quality: it was faster
and matched or beat it on the final normalized metrics. Cloud-backed mgrep is
kept in a separate, quota-interrupted exploratory track and is not part of the
local comparison.
