Other Developer Tools
Provasign is the product this site is about. The same Grove knowledge-graph engine that powers Provasign’s impact analysis and test selection also powers two standalone, MIT-licensed tools you can adopt independently. Their full documentation lives in their repositories — this page is a short orientation.
Prism — graph-ranked context for any AI agent
Prism gives an AI coding agent the right code instead of a dump of nearby files. It queries Grove, scores every candidate across five signals (graph distance, semantic similarity, recency, test relevance, edit frequency), allocates a token budget across five categories, and discloses progressively — full source on the first read, a tiny sha-pointer on re-reads.
- 35–92% fewer tokens on first reads; ~99% on same-session re-reads.
- Integrates over MCP (Claude Code, Cursor, Codex CLI, Windsurf, Continue) or as a native VS Code extension.
- Embeds Grove in-process — no daemon, no port.
Fuse — symbol-aware Git merge driver
Git merges lines; Fuse merges symbols. When one agent changes Login() and another changes validatePassword() in the same file, git sees adjacent-line conflicts where none exist. Fuse parses all three versions with Tree-sitter, queries Grove for cross-file blast radius, and resolves at symbol granularity.
- ~85% auto-resolution on incremental conflicts.
- Genuinely ambiguous conflicts get markers plus a structured AI-handoff prompt at
.git/fuse/conflict-<hash>.md. - Drops in as a git merge driver:
fuse merge %O %A %B %P.
How they relate to Provasign
| Role | License | Relationship to Provasign | |
|---|---|---|---|
| Grove | Code knowledge graph | MIT | Embedded inside Provasign (see Architecture) |
| Prism | Context delivery for agents | MIT | Standalone; shares the Grove engine |
| Fuse | Symbol-level merge driver | MIT | Standalone; shares the Grove engine |
| Provasign | Certified delivery | AGPL-3.0 | The product — embeds Grove |
You do not need Prism or Fuse to use Provasign. They solve adjacent problems in the AI-assisted workflow and happen to be built on the same foundation.
