Gemini CLI · 0.1.0

Gemini CLI Block

<!-- block-metadata:start -->

Verified BloxSmith versions: 1.0.9 (bundled-block tests; see test evidence).

<!-- block-metadata:end -->

Role

gemini_cli executes the local Gemini CLI in non-interactive mode and emits stdout.

Files

• block.py: prompt assembly, Gemini CLI process execution, stdout/stderr handling, runtime metadata, and UI rendering.
• model.json: default input/output ports, CLI config, and runtime capabilities.
• inspector_panel.html: block-owned inspector UI for instruction and CLI settings.
• block_modal.html: output-instruction modal UI with attributes and last-command tabs.
• assets/css/block_modal.css: modal layout and instruction editor styles.
• assets/js/block_modal.js: modal tab keyboard/click behavior.
• node_card.html: block-owned canvas card body.
• tests/F5.21_gemini_cli_block.py: behavior tests for centralized and zeromq_active execution.

Ports

• Inputs:
  • in (id: 1): optional input; accepts generic messages, text, and JSON.
• Outputs:
  • out (id: 1): emits Gemini CLI stdout as text/plain.

Additional output ports are supported. Each output can define its own instruction, and the block executes once per output.

Configuration

• gemini_binary: local Gemini CLI executable. Default: gemini.
• model: optional model id. When set, the runtime adds -m <model> to the command. Empty uses the CLI default.
• extra_args: optional shell-style argument string inserted before -p.
• timeout_sec: subprocess timeout.
• max_prompt_chars: local prompt guard before process launch.

Runtime Behavior

For each output, execute_runtime() builds one prompt from all non-empty named inputs plus the output instruction, then runs:

gemini [-m <model>] [extra args...] -p <prompt>

The block publishes stdout on the output port. Stderr, exit code, duration, prompt size, and the last command are persisted in runtime metadata.

The same implementation runs in One Shot Simulation (centralized) and Active Runtime (zeromq_active) through the generic block executor.

UI Behavior

The inspector and modal expose instruction, binary path, optional model, optional extra arguments, timeout, prompt guard, ports, latest runtime state, and a read-only Last cmd tab. Editable instructions and CLI settings stay local until the user clicks Apply.

The modal declares data-block-runtime-refresh="autonomous"; block-owned JS preserves tab selection, draft instructions, and command diagnostics while runtime polling is active.

Maintenance Notes

Gemini CLI behavior belongs in this block. Do not add Gemini-specific branches to the orchestrator or active runtime worker; use the generic block executor contract instead.

Compatibility policy

compatibility.json records HackInvent's verified BloxSmith versions and test evidence. Only the versions listed above have been verified, using the block-owned suites in a bundled-block test installation. This is not a certification of managed-package installation, every browser/OS, or live provider availability. Other framework versions are unverified, not necessarily incompatible.

The block-version badge follows model.json, not a published Git tag. unversioned means that no block release version is declared; no number is inferred from the framework version. The framework still uses model.json for its runtime/install contract; the tester-owned JSON does not replace it. Official integration tests run in the private bloxmith-blocs workspace. Test helpers and the proprietary framework are not bundled in this public block repository.
