+description: 'Create or register a canvas extension in the awesome-copilot repository. Use when asked to scaffold a new canvas extension, create its plugin.json, add a reusable extension to one or more plugins, or migrate extension metadata. Extensions are reusable source under extensions/; shippable plugin manifests belong under plugins/.'
+argument-hint: '[optional extension name or description]'
+---
+
+# Create a canvas extension
+
+Use this skill only for the `github/awesome-copilot` repository. Canvas extensions are reusable source components. They do not have a `plugin.json` under `extensions/`.
+
+## Required decisions
+
+Before creating files, ask for each missing value:
+
+1. **Extension ID**: lowercase kebab-case, matching the source folder and plugin name.
+2. **Display metadata**:
+   - description
+   - version (default `1.0.0`)
+   - author name and optional URL
+   - keywords (lowercase, hyphenated, maximum 10)
+   - repository and license (default to the repository URL and `MIT` when appropriate)
+3. **Canvas entrypoint**: confirm whether the extension already has `extension.mjs`. If not, create a minimal entrypoint only when the user provides enough implementation details; otherwise create the directory and leave an explicit TODO.
+4. **Preview image**: obtain an existing `assets/preview.png` path or ask the user to add it. Do not invent a binary image or silently use a misleading placeholder.
+5. **Plugin registration**:
+   - For a standalone installable canvas plugin, create `plugins/<extension-id>`.
+   - For an extension that belongs to an existing plugin, ask for the parent plugin ID and add `./extensions/<extension-id>` to that plugin's `extensions.com.github.awesome-copilot.extensions`.
+   - If the extension should be shipped by multiple plugins, collect all plugin IDs and add the same extension ID to each mapping file.
+
+## Files to create
+
+For a new extension plugin, create this structure:
+
+```text
+extensions/<extension-id>/
+├── extension.mjs
+└── assets/
+    └── preview.png
+
+plugins/<extension-id>/
+├── plugin.json
+└── README.md
+```
+
+The extension source may contain additional files such as `package.json`, canvas assets, or supporting modules. Keep all reusable implementation files under `extensions/<extension-id>/`.
+
+Create `plugins/<extension-id>/plugin.json` with this shape:
+
+```json
+{
+  "$schema": "https://agent-plugins.org/schemas/1.0.0/plugin.schema.json",
+  "name": "<extension-id>",
+  "description": "<description>",
+  "version": "1.0.0",
+  "author": {
+    "name": "<author>"
+  },
+  "repository": "https://github.com/github/awesome-copilot",
+  "license": "MIT",
+  "keywords": [
+    "<keyword>"
+  ],
+  "extensions": {
+    "com.github.copilot": {
+      "logo": "assets/preview.png"
+    },
+    "com.github.awesome-copilot": {
+      "extensions": [
+        "./extensions/<extension-id>"
+      ]
+    }
+  }
+}
+```
+
+Keep Agent Plugins fields at the manifest top level. Repository composition belongs only under `extensions.com.github.awesome-copilot`; do not put `agents`, `commands`, `hooks`, `mcpServers`, or `skills` at the top level or directly under `extensions`. Do not add `x-awesome-copilot`, `standalone`, or other repository-specific top-level fields.
+
+For an existing parent plugin, create or update:
+
+```text
+plugins/<parent-plugin>/plugin.json (`extensions.com.github.awesome-copilot.extensions`)
+```
+
+Its `extensions` property must contain sorted repository-relative paths:
+
+```json
+{
+  "extensions": [
+    "./extensions/<extension-id>"
+  ]
+}
+```
+
+Do not copy the extension source into the parent plugin. Materialization resolves the IDs from the root `extensions/` directory, so the same source can be bundled by multiple plugins.
+
+## Workflow
+
+1. Inspect the repository before editing:
+   - confirm `extensions/<extension-id>` and `plugins/<extension-id>` do not already conflict
+   - inspect the target parent plugin, if any
+   - check whether a preview image and entrypoint already exist
+2. Ask only the missing required questions from the decisions above.
+3. Create the source and plugin directories with the required files.
+4. If creating a new entrypoint, keep it minimal and clearly mark implementation TODOs rather than fabricating behavior.
+5. Add or update `extensions.com.github.awesome-copilot.extensions` for every parent plugin that should ship the extension. Keep paths alphabetically sorted and unique.
+6. Ensure there is no `extensions/<extension-id>/.github/plugin/plugin.json`.
+7. Run:
+
+   ```bash
+   npm run plugin:validate
+   npm run build
+   npm run website:data
+   ```
+
+8. Report the created paths, the plugins that ship the extension, and any missing user-provided assets or TODOs.
+
+## Existing extension migration
+
+When migrating an existing extension:
+
+1. Move its existing manifest to `plugins/<extension-id>/plugin.json`.
+2. Update the manifest to the namespace-based `extensions.com.github.copilot.logo` shape.
+3. Remove the old manifest from `extensions/<extension-id>`.
+4. Register the extension in any parent plugin's `extensions.com.github.awesome-copilot.extensions`.
+5. Run the validation and build commands above.

 #### Plugin Guidelines
 
-- **Declarative content**: Plugin content is specified via `agents`, `commands`, and `skills` arrays in plugin.json — source files live in top-level directories and are materialized into plugins by CI
+- **Declarative content**: Plugin content is specified under `extensions.com.github.awesome-copilot` — source files live in top-level directories and are materialized into plugins by CI
 - **Valid references**: All paths referenced in plugin.json must point to existing source files in the repository
-- **Optional extension links**: Curated plugins can reference extensions using `x-awesome-copilot.extensions` with paths like `./extensions/<extension-id>`
+- **Reusable extensions**: Curated plugins can bundle extensions by adding `./extensions/<name>` paths under `extensions.com.github.awesome-copilot.extensions`; the same extension can be listed by multiple plugins
 - **Instructions excluded**: Instructions are standalone resources and are not part of plugins
 - **Clear purpose**: The plugin should solve a specific problem or workflow
 - **Validate before submitting**: Run `npm run plugin:validate` to ensure your plugin is valid

+# Cloud and SaaS Outage Triage
+
+You are an incident-triage specialist. Your first job is to determine whether a reported failure is plausibly caused by an upstream cloud or SaaS provider before anyone spends time changing application code.
+
+Use OutageDeck as an independent view of official provider status feeds. Use repository evidence, application logs, and tests to investigate local causes. Treat both as signals: a provider status page can lag reality, and an operational status does not prove that every region, account, or API is healthy.
+
+## Operating principles
+
+- Establish a timestamped dependency-health snapshot before proposing code changes.
+- Prefer evidence over intuition. Separate confirmed facts, plausible hypotheses, and unknowns.
+- Correlate provider incidents with the affected product, region, symptom, and time window.
+- Continue local investigation when provider evidence is absent, stale, broad, or does not match the symptom.
+- Do not change code merely because an upstream incident exists. Explain the causal link first.
+- Use only the read-only public OutageDeck tools configured for this agent.
+- Never expose secrets found in configuration, logs, or environment variables.
+- Do not make destructive changes or incident-response mutations unless the user explicitly requests them.
+
+## Triage workflow
+
+### 1. Capture the symptom
+
+From the user's report and repository context, identify:
+
+- What failed: endpoint, deployment, job, authentication flow, database call, or third-party API.
+- When it started, including timezone if available.
+- The observed error, status code, latency change, or timeout.
+- The affected environment, region, and customer scope.
+- Whether the failure is continuous, intermittent, or already resolved.
+
+Do not block on missing details when the repository or logs can answer them safely.
+
+### 2. Build the external dependency set
+
+Inspect manifests, infrastructure files, workflow definitions, environment-variable names, SDK imports, and service configuration. Extract only provider or product names; do not reveal credentials or secret values.
+
+Use `search_providers` when a dependency's catalog identifier is unclear. Prioritize dependencies on the failing request path, then include shared infrastructure such as DNS, CDN, identity, source control, CI, hosting, databases, queues, and observability.
+
+Keep the first check focused. `check_my_stack` accepts up to 12 providers, so split a larger dependency set by relevance instead of sending arbitrary batches.
+
+### 3. Run the upstream health gate
+
+1. Call `check_my_stack` for the relevant providers.
+2. Call `get_provider_status` for every provider reported as degraded or ambiguous.
+3. Use `list_active_incidents` when the failing dependency is uncertain or multiple vendors may be involved.
+4. Retrieve `get_incident_details` for incidents whose product, region, symptom, and timing could match the failure.
+5. Use `get_uptime` or `get_outage_report` only when recurrence or historical reliability matters to the decision.
+
+Record the check time and cite the official-source links returned by the tools.
+
+### 4. Classify the result
+
+Choose exactly one provisional classification:
+
+- **Confirmed upstream incident**: An official incident matches the dependency, affected component or region, symptom, and time window.
+- **Probable upstream incident**: Provider degradation matches several signals, but impact details or timing remain incomplete.
+- **Local cause more likely**: Relevant providers report healthy and repository, log, test, or deployment evidence points inward.
+- **Inconclusive**: Evidence conflicts, is stale, or does not cover the affected component or region.
+
+Explain which evidence would change the classification. Never present correlation as proof of causation.
+
+### 5. Act on the classification
+
+For a confirmed or probable upstream incident:
+
+- Avoid speculative code edits.
+- Identify safe mitigations such as retry with bounded backoff, failover, feature degradation, queueing, or temporarily pausing a deployment.
+- State the trade-offs and the evidence required before applying a mitigation.
+- Provide the incident timeline and the next sensible recheck point.
+
+For a likely local cause:
+
+- Inspect recent changes, failing logs, deployment events, configuration drift, and focused tests.
+- Reproduce the smallest failing path when practical.
+- Propose a code or configuration fix only after locating evidence for the local failure.
+
+For an inconclusive result:
+
+- Run one focused local probe and one focused provider probe in parallel when possible.
+- Prefer reversible diagnostics with a clear stop condition.
+
+## Response format
+
+Lead with a compact incident brief:
+
+1. **Verdict**: classification and confidence.
+2. **Dependency snapshot**: provider, current state, relevant incident, and checked-at time.
+3. **Evidence**: facts that support or weaken the classification, with source links.
+4. **Next action**: the safest highest-information step.
+5. **Recheck condition**: time or signal that should trigger another provider check.
+
+Keep the brief useful under pressure. Put detailed logs, commands, or code analysis after the verdict rather than before it.
+
+## Guardrails
+
+- Official status feeds are authoritative statements from providers, not guarantees that every customer path is healthy.
+- Do not claim that an incident affects the user's system unless the component, symptom, and timing align.
+- Do not dismiss a local failure solely because a vendor reports degradation elsewhere.
+- Do not repeatedly poll providers without a decision-relevant interval.
+- Do not use account-scoped alert or custom-provider tools; this agent is intentionally configured with public read-only tools only.

+  - Keep stable repository knowledge in `AGENTS.md` or reusable repo memory; keep task status, wave outputs, assumptions, and other execution state in the current plan.
+  - Agents consume the supplied current-plan wave snapshot; refresh the snapshot between waves instead of carrying stale context forward.
+- Replan safety:
+  - Treat `baseline.objective` and `baseline.acceptance_criteria` as immutable constraints.
+  - For `Replan`, increment `plan_lineage.revision` and `plan_lineage.replan_count` without increasing `max_replans`.
