Helmor is a local workbench for running and coordinating multiple coding agents, with each task isolated in its own Git workspace. Developers use it to review changes, test code, resolve conflicts, and merge or create pull requests. Its catalogue entries extend Helmor with skills, instructions, settings, and hooks.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.04327 | $0.04327 |
| Opus 5.5 | $0.01731 | $0.01731 |
| Sonnet 5.5 | $0.00865 | $0.00865 |
| Haiku 4.5 | $0.00433 | $0.00433 |
Grade A, and why
helmor CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What is Helmor
Helmor is a local-first desktop app built with Tauri v2 (Rust backend) + React 19 + Vite + TypeScript. It provides a workspace management UI with its own SQLite database (~/helmor/ in release, ~/helmor-dev/ in debug), letting users browse workspaces/sessions/messages and send prompts to AI agents (Claude Code CLI, OpenAI Codex CLI) via streaming IPC.
Commands
bun install # Install deps (bun 1.3+). Also runs `bun install` in sidecar/ via postinstall.
bun run dev # Full desktop app: Tauri + Vite (localhost:1420 in webview)
bun run dev:analyze # Same as dev, with perf HUD (VITE_HELMOR_PERF_HUD=1)
bun run build # tsc + vite build (frontend bundle to dist/)
bun run typecheck # tsc --noEmit for frontend AND sidecar
bun run lint # biome check . + cargo clippy -- -D warnings
bun run lint:fix # biome --write + cargo clippy --fix + cargo fmt
Tests are three targets — bun run test runs all three (frontend -> sidecar -> rust). Pre-commit hook runs biome on JS/TS and clippy/fmt on Rust.
bun run test # All three suites
bun run test:frontend # vitest run (jsdom, @testing-library/react)
bun run test:sidecar # cd sidecar && bun test
bun run test:rust # cd src-tauri && cargo test
bun run test:rust:update-snapshots # INSTA_UPDATE=always
bun run test:watch # vitest watch (frontend only)
Single test file: bun x vitest run src/App.test.tsx | cd sidecar && bun test src/foo.test.ts | cd src-tauri && cargo test --test pipeline_scenarios -- <name>
Architecture
Three-process model
- Frontend (
src/): React 19 SPA in Tauri webview. State management handled by specialized hooks (useAppShellState,useSelectionController,useEditorEditMode,useGlobalShortcutHandlers,useAppBootstrap) undersrc/shell/. TanStack React Query + context providers. - Rust backend (
src-tauri/src/): Tauri host, SQLite database, spawns and supervises the sidecar. - Sidecar (
sidecar/): Bun + TypeScript, wraps@anthropic-ai/claude-agent-sdkand@openai/codex(CLI). Built tosidecar/dist/helmor-sidecarviabun build --compile. JSON event stream over stdout.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
