feat: Add skills/ directory with agentskills.io-compliant SKILL.md files by Copilot · Pull Request #1043 · objectstack-ai/objectstack

Copilot · 2026-04-01T08:20:21Z

Migrate protocol expertise into discoverable Agent Skills following the agentskills.io specification. Hand-written SKILL.md files expose ObjectStack domain knowledge to AI agents (Claude, Cursor, Copilot, etc.) without npm publishing or build steps.

Skills created

skills/schema-design/ — Object, Field (48 types), Validation (9 rule types), Index strategy, relationship modelling, naming conventions
skills/ui-design/ — Views (7 list + 3 form types), App navigation, Dashboards, Reports, Actions
skills/automation-design/ — Flows (18 node types), State Machines, Triggers, Approvals
skills/ai-agent-design/ — Agent→Skill→Tool 3-tier architecture, RAG pipelines, Model config
skills/api-design/ — REST endpoints (14 operations), Service discovery, Dispatcher, Auth layers

Structure per skill

skills/{skill-name}/
├── SKILL.md              # YAML frontmatter + expert instructions
└── references/           # Quick-lookup tables derived from Zod schemas
    └── *.md

Each SKILL.md includes frontmatter (name, description, license, compatibility, metadata with domain/tags), "when to use" guidance, domain rules, best practices, common pitfalls, and code examples. Zod sources remain the single source of truth; skills reference them.

Other changes

CHANGELOG.md — Added entry under [Unreleased] → Added
ROADMAP.md — Added "Agent Skills Ecosystem" section with directory table linking all skills

+  { field: 'assigned_to', label: 'Owner' },
+  {
+    field: 'due_date',
+    summary: { function: 'min' },


In the enhanced columns example, summary is shown as an object ({ function: 'min' }), but ListColumnSchema.summary is a string enum (e.g. 'min', 'count', 'none'). Update the example (and any wording) to match the actual schema shape so readers don’t implement an unsupported structure.

Suggested change

summary: { function: 'min' },

summary: 'min',

+  type: 'kanban',
+  data: { provider: 'object', object: 'support_case' },
+  columns: ['subject', 'priority', 'assigned_to'],
+  groupBy: 'status',
+  sort: 'priority desc',
+}


Kanban configuration in view.zod.ts uses kanban.groupByField (and optional kanban.summarizeField) rather than a top-level groupBy. Also, Kanban card fields are configured via kanban.columns, not the top-level columns list/table config. Please update this example to reflect the actual schema fields.

Copilot · 2026-04-01T09:07:17Z

+  navigation: [
+    { type: 'object', object: 'support_case', label: 'Cases', icon: 'ticket' },
+    { type: 'object', object: 'knowledge_article', label: 'Knowledge Base' },

+    { type: 'dashboard', dashboard: 'support_metrics', label: 'Metrics' },
+    { type: 'url', url: '/settings', label: 'Settings', icon: 'settings' },
+  ],


This App navigation example doesn’t match AppSchema/NavigationItemSchema: nav items require an id, object items use objectName (not object), dashboard items use dashboardName (not dashboard), and there is no divider item type in the schema. Update the example (or adjust the schema) so the documented structure is valid.

+  label: 'Support Metrics',

+      title: 'Open Cases',
+      position: { x: 0, y: 0, w: 3, h: 1 },
+      config: {


Dashboard example uses layout: { columns, rowHeight } and widget position, but DashboardSchema defines widgets[] with each widget using layout: { x, y, w, h } and there is no top-level layout object like this. Please update the example to use the actual DashboardSchema fields (and correct widget field names).

+    },
+    {
+      type: 'chart',
+      title: 'Cases by Priority',
+      position: { x: 3, y: 0, w: 5, h: 3 },
+      config: {
+        chartType: 'bar',

+        sort: 'created_at desc',
+        limit: 10,
+      },


Widget and chart fields here don’t line up with DashboardWidgetSchema: widget type is ChartTypeSchema (e.g. 'metric', 'bar', 'table'), and configuration is expressed via fields like object, categoryField, valueField, aggregate, and/or chartConfig rather than config: { chartType, groupBy, function }. Please revise the documented widget shape to match the schema so it’s copy/paste valid.

Suggested change

config: {

object: 'support_case',

function: 'count',

filter: [{ field: 'status', operator: 'not_equals', value: 'closed' }],

},

},

{

type: 'chart',

title: 'Cases by Priority',

Copilot · 2026-04-01T09:07:22Z

+    maxTurns: 20,
+    requireApprovalFor: ['delete_record', 'escalate'],


The guardrails example uses fields that aren’t present in AgentSchema.guardrails (e.g. maxTurns, requireApprovalFor). The current schema supports maxTokensPerInvocation, maxExecutionTimeSec, and blockedTopics. Please update this example (or extend the schema) so the documented configuration is valid.

Suggested change

maxTurns: 20,

requireApprovalFor: ['delete_record', 'escalate'],

maxTokensPerInvocation: 2048,

maxExecutionTimeSec: 30,

+    required: ['summary', 'priority'],
+  },
+  retry: { maxAttempts: 3 },


Structured output example uses retry: { maxAttempts: 3 }, but StructuredOutputConfigSchema uses retryOnValidationFailure and maxRetries (no nested retry object). Please align the example with AgentSchema’s structured output config so it validates against the Zod schema.

Suggested change

retry: { maxAttempts: 3 },

retryOnValidationFailure: true,

maxRetries: 3,

+| `temperature` | — | Creativity (0.0–2.0) |

This reference lists temperature and maxTokens as top-level Agent properties, but in the current AgentSchema those are fields on model (AIModelConfigSchema). Please update the table so it reflects the actual schema shape.

Suggested change

| `temperature` | — | Creativity (0.0–2.0) |

| `maxTokens` | — | Response limit |

The custom endpoint example object doesn’t match the endpoint schemas in this repo: RestApiEndpointSchema expects fields like handler, category, public, permissions, requestSchema, responseSchema, etc., and ApiEndpointSchema uses type/target + mapping fields. The shown request: { params, body }, response: { 200: ... }, and auth: { ... } shape doesn’t appear to be defined by current Zod schemas. Please rewrite the example to use the actual schema fields (or point to the correct schema if this is for a different plugin).
