canva-load-scale
Design a mock-first Canva capacity test and a tightly authorized provider probe. Use when sizing queues, workers, token-refresh serialization, or endpoint concurrency without inventing universal quotas. Trigger with: "load test Canva", "size Canva workers", "Canva capacity plan".
Why this skill is useful
Provides specific k6 load testing scripts and capacity planning strategies tailored for Canva's API rate limits.
What it needs
Requires k6 installed locally. Requires canva account access. About 2k tokens when loaded. Last updated 2026-08-07. 2,604 stars on the source repository.
What this skill does
Canva Bounded Capacity Test Overview Measure your application under a declared workload while honoring endpoint-specific Canva metadata and actual responses. Default to mocks; a live probe must be small, reversible, and isolated. Prerequisites Approved workload model, test target, user count, and abort thresholds Mock contract plus current endpoint rate metadata Synthetic assets, dedicated users, cleanup plan, and provider-test authorization Instructions Step 1: Model operations Define logical reads, writes, async submissions, polling, refresh, and webhook processing separately. Include bursts, retries, and job completion distribution. Step 2: Exercise mocks first Use Write or Edit to implement contract-faithful responses for success, throttling, auth failure, in-progress, terminal failure, and schema drift. Step 3: Size application limits Measure queue depth, worker utilization, latency, memory, refresh lock contention, and database pressure; set local admission and concurrency below measured safe points. Step 4: Authorize a provider probe Limit it to named endpoint/user, request count, duration, and synthetic data. Avoid mutating operations unless their cleanup and duplicate impact are approved. Step 5: Abort aggressively Stop on unexpected authorization, data, sustained throttling, provider error, cleanup failure, or impact outside the named test. Step 6: Produce capacity evidence Use Write or Edit to record workload, environment, contract version, aggregate results, observed provider responses, chosen headroom, and rollback. Authentication Canva Connect calls use Bearer access tokens obtained by a backend through OAuth 2.0 Authorization Code with SHA-256 PKCE. Request explicit least-privilege scopes, keep client secrets and tokens out of browser-visible state, and serialize refresh so the replacement single-use refresh token is stored atomically. Tool Discipline Use Read and Grep for discovery and evidence. …
