Go TUI on top of tmux that spawns, tracks, and reviews Claude Code, Codex, Cursor, and other coding agents in one keypress.

One-keypress Spawn: Hit space on a group row, type the task, press enter — a new agent session starts immediately with the prompt embedded and the correct working directory set, without any form or naming step.
Answer In Place: On a session row, the same space key sends your reply into the agent's pane as a user message, so a blocked agent never costs you a tmux attach.
Multi-CLI Support: Tab cycles which CLI the next enter launches — claude, opencode, codex, grok, gemini, or anything you configured — so different tasks pick different agents from the same bar.
Git Worktree Spawn: alt+w spawns the agent into a fresh git worktree so parallel branches don't fight over the checkout.
Hook-based Status Detection: Six statuses (working, waiting, finished, errored, idle, dead) come from Claude Code's own hook events rather than guessing from pane output.
Foldable Project Tree: Groups are paths, not folders — backend/api/auth nests as deep as the work does, folded groups keep per-status counts, and the layout persists across restarts.
Whole-file Diff Reviewer: Review each agent's diff without leaving the list; line comments become follow-up messages to that agent.
Uses Your Local CLI As-is: Every session runs your installed CLI with your login, config, and MCP servers — nothing is re-wrapped or proxied.

Parallel Feature Work: Fan out five features across five agents in seconds and monitor them all in one folded tree without switching terminals.
Reviewing Blocked Agents: Answer a permission prompt or clarifying question directly from the list without tmux-attaching, so waiting agents never idle on you.
Multi-repo Development: Keep several projects open at once, spawn each new task into the correct project directory, and never lose track of which agent is where.
Mixed CLI Workflows: Use Claude Code for one task, Codex for another, and opencode for a third — all launched from the same TUI without switching contexts.
Diff-driven Code Review: Scan a whole-file diff, drop a line comment, and it becomes the next message to the agent, closing the review-fix loop inside the TUI.
Long-running Agent Fleets: Fold what you aren't watching, archive finished sessions, and let dozens of agents run without the terminal turning into a wall of processes.

Reads your repositories to discover every API, scores and governs them, then exposes them to developers and AI agents via hosted MCP servers.

Spec-Free API Discovery: Elva scans repository code directly to find endpoints and generates OpenAPI 3.1 as output, so no existing spec is needed to start.
Endpoint Scoring: Every collection is graded on design, developer experience, AI readiness, security and performance, with the weakest collection surfaced first.
AI Fix Pass: A one-click agent writes missing descriptions from code, types response schemas and documents auth, then rescores the collection.
API Contracts: Per-audience contracts pin the exact endpoints and fields a partner, internal team, public developer or MCP client receives, excluding PII and internal fields.
Breaking Change Enforcement: Each commit is diffed against published contracts, showing the schema diff, affected consumers and tools, and blocking publish by policy.
Hosted MCP Servers: Contracts generate MCP servers hosted behind Elva's gateway with OAuth2, scoped keys, per-tool authorization and exportable call logs.
MCP Playground and Agent Feedback: Test the server with a live model, then read the complaints agents file about confusing or failing tools, scored back into the catalog.
Multi-Target Publishing: One approved contract ships as OpenAPI spec, Theneo docs, MCP server, Postman collection and a typed TypeScript SDK in sync.

API Inventory Audit: Discover undocumented or forgotten endpoints across a large codebase and get a ranked list of what to fix first.
Agent Enablement: Expose an internal service to Claude, Cursor or ChatGPT as a governed MCP server instead of hand-writing tool wrappers.
Partner Integration Safety: Publish a restricted contract to an external partner and have Elva block commits that would break their integration.
PII Scoping: Keep customer emails and internal ops annotations out of a public or agent-facing surface while the same endpoints serve them internally.
Zombie Endpoint Retirement: Prove no active consumer references an endpoint before deleting it, using contract and call-log evidence.
Enterprise Security Review: Satisfy SOC 2, ISO 27001 and GDPR questions and wire agent access into an existing SSO and SCIM identity provider.
Documentation Drift Control: Keep docs, SDKs and Postman collections regenerated from code on every merge instead of maintained by hand.
