Analyze and classify Canva Connect failures by HTTP status, provider error code, operation, and authorization state.

  • Works in 6 steps: Capture a minimal envelope → Handle authentication failures → Handle authorization failures → …

  • SKILL.md covers Overview, Prerequisites, Instructions and Authentication, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Canva Common Errors is an agent skill from jeremylongshore/tons-of-skills-marketplace. Analyze and classify Canva Connect failures by HTTP status, provider error code, operation, and authorization state. Use when deciding whether to refresh, reauthorize, wait, reconcile, correct input, or escalate. Trigger with: "Canva API error", "Canva 401", "Canva 403 or 429".

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Diagnosis may use redacted production evidence; any live reproduction requires an approved test user and operation.

It sits in Backend & APIs, covering Authorization and RBAC. It works with Canva. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Deciding whether to refresh
  • With: Canva API error

Example prompts

  • “Canva API error”
  • “Canva 401”
  • “Canva 403 or 429”
  • “/canva-common-errors”

Requirements

  • Compatibility (from SKILL.md): Diagnosis may use redacted production evidence; any live reproduction requires an approved test user and operation.
  • Pre-approved tools (allowed-tools): Read, Grep, Write, Edit

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Capture a minimal envelope
  2. Handle authentication failures
  3. Handle authorization failures
  4. Handle throttling
  5. Handle async failures
  6. Escalate provider failures

What it can do on your machine

Read from SKILL.md and the folder at commit 23ea8d4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Grep
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • canva.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Diagnosis may use redacted production evidence; any live reproduction requires an approved test user and operation.

    From compatibility in the SKILL.md frontmatter.

Context cost

Canva Common Errors loads about 1k tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 75 tokens; SKILL.md has 413 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Canva Error Classification

Overview

Treat HTTP status alone as insufficient. Use the current endpoint reference and redacted provider error code to separate caller defects, authorization failures, throttling, preview drift, and provider incidents.

Prerequisites

  • HTTP status, provider error code, endpoint pattern, and UTC window
  • Opaque request, resource, or job reference without payload content
  • Pinned OpenAPI or endpoint documentation version

Instructions

Step 1: Capture a minimal envelope

Record method, endpoint pattern, status, provider code, terminal job state, retry metadata if actually present, and deployment version. Exclude tokens, bodies, signed URLs, and customer identifiers.

Step 2: Handle authentication failures

For an invalid or expired access token, serialize the authorized refresh flow and atomically store the replacement refresh token. Reauthorize after revocation or unrecoverable refresh failure.

Step 3: Handle authorization failures

Compare the operation with explicit granted scopes, resource ownership, capabilities, tenant policy, and preview availability. Never assume a write scope grants its read counterpart.

Step 4: Handle throttling

Pause only the affected endpoint/user queue. Use documented endpoint metadata and response instructions; otherwise apply bounded exponential backoff with jitter rather than a guessed fixed delay.

Step 5: Handle async failures

Poll the existing job to a documented terminal state. Correct validation or entitlement errors before any new submission.

Step 6: Escalate provider failures

Correlate repeated server errors with Canva status/changelog and provide a redacted support receipt after bounded retry is exhausted.

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. Use Write or Edit only for the approved artifact, code, configuration, test, or receipt described by this workflow; do not make an unapproved Canva-side change.

Output

  • Scoped decision or implementation artifact
  • Redacted operation and validation receipt
  • Failure, rollback, and follow-up ownership record

Examples

An autofill returns HTTP 403. The operator checks explicit scopes, current capability and Enterprise availability, template ownership, preview status, and the provider error before deciding whether reauthorization is relevant.

Error Handling

FailureResponse
Only HTTP status is availableCollect the redacted provider envelope before acting
Refresh repeats 401Stop and require reauthorization instead of looping
429 has no retry metadataUse the local bounded backoff policy and lower concurrency
Job failed validationCorrect the request; do not retry unchanged input
