Live package: sha256:914d3972d1e9577538f9f5f96871a0f428431248dff81c8a5a13e643ef02e280 with 2 file digest(s); the catalog entry is generated from the built package, not a placeholder.

Props

The prop schema is normative in packages/contracts/component-props/terminal.schema.json.

Example props generated from this schema:

{
  "title": "example-title",
  "commands": [
    "example-commands"
  ],
  "resource": {
    "resource_id": "00000000-0000-4000-8000-000000000000",
    "operation": "example-operation",
    "environment": "test"
  },
  "cwd": "example-cwd",
  "read_only": true,
  "timeout_seconds": 1
}

Required props: commands, read_only, timeout_seconds.

Example

Example document IR (the block the renderer consumes):

{
  "type": "terminal",
  "props": {
    "title": "example-title",
    "commands": [
      "example-commands"
    ],
    "resource": {
      "resource_id": "00000000-0000-4000-8000-000000000000",
      "operation": "example-operation",
      "environment": "test"
    },
    "cwd": "example-cwd",
    "read_only": true,
    "timeout_seconds": 1
  }
}

Renderer HTML (entities decoded and wrapped for display):

<section class="ds-block ds-terminal" data-component="terminal" aria-labelledby="b-title">
<h3 class="ds-block-title" id="b-title">example-title</h3>
<pre class="ds-code" data-lang="shell">
<code>example-commands</code>
</pre>
<dl class="ds-facts">
<div>
<dt>Working directory</dt>
<dd>
<code>example-cwd</code>
</dd>
</div>
<div>
<dt>Mode</dt>
<dd>Read-only</dd>
</div>
<div>
<dt>Time limit</dt>
<dd>1 s</dd>
</div>
<div>
<dt>Runs</dt>
<dd>
<code>example-operation</code> in the test environment</dd>
</div>
</dl>
<p class="ds-live-note" role="note">Running these commands needs the live documentation site; copy them to run them yourself.</p>
</section>

Preview (interface-only; the markup above is the same output):

example-commands

The renderer resolves this component as a native block; the preview above is its real HTML output, and Markdown parity for native blocks is covered by the renderer test suite.

Specification

Generated from packages/contracts/component-specs/terminal.md.

Contract

Production props are normative in ../contracts/component-props/terminal.schema.json. The corresponding component-fixtures manifest is only a minimal protocol fixture; use the production props schema when building the published package. The packaged artifact ships exactly its generated component-package.json manifest plus props.schema.json (the production props schema, copied byte-for-byte) and spec.md (this spec, copied byte-for-byte); it contains no executable payload, fallback implementation, Storybook, test suite, SSR harness or README. Rendering behavior and the acceptance cases below belong to the renderer and the repository tests, not to the package. Installation pins the package version and the digest of every shipped byte.

Intended behavior

Display typed commands and simulated output; live mode isolated sandbox, shell strings never interpolated into host shell.

Failure and fallback

Write denied outside sandbox; show simulation label.

Required acceptance cases

User-entered command cannot access control-plane FS or instance metadata. Also test empty data, loading, denied access, browser without JS, mobile 360px, keyboard navigation, dark mode and an explicit constrained agent tool call. The server independently authorizes capability requests; a package manifest cannot grant authority.

Data and maintenance

Data bindings resolve from a specific publication/release vector and permitted fact/evidence graph. Configuration edits create versioned component patches. Update invalidation uses dependency IDs, never indiscriminate whole-page regeneration. Human-owned props survive automatic updates unless invalidated with an explicit conflict. Missing optional resources leave an honest inert/readable fallback, not a broken page or fake success.

Cost and tools

Pure/local interaction must never invoke a model by accident. Any model, remote query or executor call must reserve approved budget before dispatch. Public visitors do not inherit owner resources. The component may call only named tools in its signed manifest with valid typed inputs. A cancelled job stops polling and closes resources. No component gets platform administration, raw credentials or an unlimited execution loop.

Package manifest

Protocol fixture: packages/contracts/component-fixtures/terminal.json.
