Use when asked to support a new resource in the polyai-adk repo.\nmetadata:\ninternal: true</h2>\n<h1>Add a resource type</h1>\n<p>Read <code>src/poly/resources/AGENTS.md</code> first; this skill expands its checklist.</p>\n<h2>1. Study an existing resource</h2>\n<ul>\n<li><code>src/poly/resources/entities.py</code>: a simple <code>YamlResource</code>.</li>\n<li><code>src/poly/resources/resource.py</code>: the base classes, <code>register_resource</code> and\n<code>load_resources_from_projection</code>.</li>\n<li><code>src/poly/resources/__init__.py</code>: where classes are imported.</li>\n<li><code>AgentStudioProject.find_new_kept_deleted</code> and <code>_make_resource_mapping</code> in <code>src/poly/project.py</code>:\nhow resource types are handled generically.</li>\n<li>For a resource that belongs to a parent (a step in a flow, an overwrite in a variant):\n<code>FlowStep</code> in <code>flows.py</code>. It stores the parent id and name as fields and resolves them from the\nenclosing folder name in <code>read_local_resource</code>.</li>\n</ul>\n<h2>2. Write the class</h2>\n<p>Create <code>src/poly/resources/&lt;name&gt;.py</code>:</p>\n<ul>\n<li>Subclass <code>YamlResource</code> (or <code>Resource</code> / <code>MultiResourceYamlResource</code>) and implement the\nabstract methods:\n<ul>\n<li><code>command_type</code></li>\n<li><code>build_create_proto</code>, <code>build_update_proto</code>, <code>build_delete_proto</code></li>\n<li><code>file_path</code>, <code>raw</code>, <code>validate</code></li>\n<li><code>to_yaml_dict</code>, <code>from_yaml_dict</code></li>\n<li><code>from_projection</code>, <code>read_local_resource</code>, <code>discover_resources</code></li>\n</ul>\n</li>\n<li>Add <code>make_pretty</code> / <code>from_pretty</code> if names or IDs need substituting, and\n<code>get_resource_prefix()</code> if other resources can reference this one.</li>\n<li>Decorate it with <code>@register_resource(\"&lt;name&gt;\")</code>. That fills <code>RESOURCE_NAME_TO_CLASS</code>,\n<code>RESOURCE_CLASS_TO_NAME</code> and <code>PROJECTION_REGISTRY</code>. There is no other registration step.</li>\n<li><code>from_projection</code> is a classmethod that parses its own keys out of the raw projection dict.</li>\n<li><code>validate</code> should reject everything the platform would reject.</li>\n</ul>\n<h2>3. Wire it in</h2>\n<ul>\n<li>Import the class in <code>src/poly/resources/__init__.py</code>, which makes the decorator run.</li>\n<li>If the file name is a cleaned version of the real name (accents, casing or punctuation\nstripped, like <code>Topic</code> and <code>ChildTopic</code>), add the class to the name-recovery condition in\n<code>find_new_kept_deleted</code> in <code>src/poly/project.py</code>, and import it there.</li>\n</ul>\n<h2>4. Test it</h2>\n<p>In <code>src/poly/tests/resources_test.py</code> (see the <code>write-tests</code> skill), cover:</p>\n<ul>\n<li>the YAML round-trip</li>\n<li><code>validate</code> (valid and invalid)</li>\n<li><code>file_path</code></li>\n<li><code>from_projection</code></li>\n</ul>\n<p>For a parent-scoped resource, also test that <code>read_local_resource</code> resolves the parent from the\nfolder name and copes with an empty <code>resource_mappings</code> list.</p>\n<p>Add an example of the resource to <code>src/poly/tests/test_projects/test_project/</code>.</p>\n<h2>5. Document it</h2>\n<ul>\n<li><code>src/poly/docs/&lt;name&gt;.md</code>: the YAML shape, served by <code>poly docs</code>.</li>\n<li><code>docs/docs/reference/resources/</code>: follow the <code>AGENTS.md</code> in that directory, and add the page to\n<code>docs/mkdocs.yml</code>.</li>\n<li>If a user skill in <code>skills/</code> describes the area, update it.</li>\n</ul>\n<h2>6. Check</h2>\n<p><code>uv run ruff check . --fix</code>, <code>uv run ruff format .</code>, then the <code>ci-check</code> skill. Never touch\n<code>src/poly/handlers/protobuf/</code> or <code>src/poly/types/</code>; if the protobufs lack the resource, stop and\nsay so.</p>\n","files":[{"path":"SKILL.md","sizeBytes":3166,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
