Diagnose and fix common Evernote API errors. An agent skill from jeremylongshore/tons-of-skills-marketplace.

  • Encountering Evernote API exceptions
  • SKILL.md covers Overview, Prerequisites, Instructions and Output, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Debugging failures

What it does

Evernote Common Errors is an agent skill from jeremylongshore/tons-of-skills-marketplace. Diagnose and fix common Evernote API errors. Use when encountering Evernote API exceptions, debugging failures, or troubleshooting integration issues. Trigger with phrases like "evernote error", "evernote exception", "fix evernote issue", "debug evernote", "evernote troubleshooting".

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/implementation-guide.md`). Compatibility notes: Designed for Claude Code

It sits in Development, covering Debugging. 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

  • Encountering Evernote API exceptions
  • Debugging failures
  • Troubleshooting integration issues
  • With phrases like evernote error

Example prompts

  • “evernote error”
  • “evernote exception”
  • “fix evernote issue”
  • “/evernote-common-errors”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Grep

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. 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
    • Write
    • Edit
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).

    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):

    • dev.evernote.com
    • xml.evernote.com

    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

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Evernote Common Errors loads about 1.3k tokens when it runs, and up to ~4k if it reads all its reference files. Until then it costs about 77 tokens; SKILL.md has 345 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~77
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4k

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.

Evernote Common Errors

Overview

Comprehensive guide to diagnosing and resolving Evernote API errors. Evernote uses three exception types: EDAMUserException (client errors), EDAMSystemException (server/rate limit errors), and EDAMNotFoundException (invalid GUIDs).

Prerequisites

  • Basic Evernote SDK setup
  • Understanding of Evernote data model

Instructions

EDAMUserException Error Codes
CodeNameCauseFix
1BAD_DATA_FORMATInvalid ENML, missing DOCTYPEValidate ENML before sending; check for forbidden elements
2DATA_REQUIREDMissing required field (title, content)Ensure note.title and note.content are set
3PERMISSION_DENIEDAPI key lacks permissionsRequest additional permissions from Evernote
4INVALID_AUTHInvalid or revoked tokenRe-authenticate user via OAuth
5AUTH_EXPIREDToken past expiration dateCheck edam_expires, refresh token
6LIMIT_REACHEDAccount limit exceeded (250 notebooks)Clean up resources before creating new ones
7QUOTA_REACHEDMonthly upload quota exceededCheck user.accounting.remaining
ENML Validation

The most common error is BAD_DATA_FORMAT from invalid ENML. Validate before sending:

javascript
function validateENML(content) {
  const errors = [];
  if (!content.includes('<?xml version="1.0"')) errors.push('Missing XML declaration');
  if (!content.includes('<!DOCTYPE en-note')) errors.push('Missing DOCTYPE');
  if (!content.includes('<en-note>')) errors.push('Missing <en-note> root');

  const forbidden = [/<script/i, /<form/i, /<iframe/i, /<input/i];
  forbidden.forEach(p => { if (p.test(content)) errors.push(`Forbidden: ${p.source}`); });

  if (/\s(class|id|onclick)=/i.test(content)) errors.push('Forbidden attributes');
  return { valid: errors.length === 0, errors };
}
EDAMSystemException Handling

Rate limit errors include rateLimitDuration (seconds to wait). Maintenance errors should be retried with progressive backoff.

javascript
async function withRetry(operation, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await operation();
    } catch (error) {
      if (error.rateLimitDuration) {
        await new Promise(r => setTimeout(r, error.rateLimitDuration * 1000));
        continue;
      }
      throw error;
    }
  }
}
EDAMNotFoundException Handling

Thrown when a GUID does not exist (deleted note, wrong user, invalid format). Handle gracefully by returning null instead of throwing.

javascript
async function safeGetNote(noteStore, guid) {
  try {
    return await noteStore.getNote(guid, true, false, false, false);
  } catch (error) {
    if (error.identifier === 'Note.guid') return null;
    throw error;
  }
}
Error Handler Service

Build a centralized error handler that classifies exceptions and returns structured results with type, code, action, and recoverable flags. See Implementation Guide for the complete EvernoteErrorHandler class.

Output

  • Error code reference table for all EDAMUserException codes
  • ENML validation utility that catches common content errors
  • Rate limit retry with rateLimitDuration handling
  • Safe getter pattern for EDAMNotFoundException
  • Centralized EvernoteErrorHandler service class

Error Handling

ExceptionWhen ThrownRecovery
EDAMUserExceptionClient error (invalid input, permissions)Fix input or re-authenticate
EDAMSystemExceptionServer error (rate limits, maintenance)Wait and retry
EDAMNotFoundExceptionResource not found (invalid GUID)Verify GUID, check trash

Next Steps

For debugging tools and techniques, see evernote-debug-bundle.

Examples

ENML debugging: Note creation fails with BAD_DATA_FORMAT. Run validateENML() on the content to identify missing DOCTYPE, unclosed tags, or forbidden elements like <script>.

Token refresh flow: API call returns AUTH_EXPIRED (code 5). Check stored edam_expires timestamp, redirect user to OAuth re-authorization, store new token with updated expiration.
