What it does
Clade Data Handling is an agent skill from jeremylongshore/tons-of-skills-marketplace. Handle sensitive data with Claude — PII redaction, conversation management, Use when working with data-handling patterns. context window optimization, and data retention policies. Trigger with "anthropic data privacy", "claude pii", "anthropic context window", "manage claude conversations", "anthropic data retention".
Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/one-pager.md`). Compatibility notes: Designed for Claude Code
It sits in Agent Workflows, covering Context engineering and Privacy and GDPR. 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.

- Working with data-handling patterns

- Anthropic context window
- Manage claude conversations
Example prompts
- “anthropic data privacy”
- “claude pii”
- “anthropic context window”
- “/clade-data-handling”
Requirements
- Compatibility (from SKILL.md): Designed for Claude Code
- Pre-approved tools (allowed-tools): Read, Write, Edit
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:
ReadWriteEdit
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 typescript).
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):
platform.claude.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
Clade Data Handling loads about 902 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 85 tokens; SKILL.md has 188 words of instructions outside code blocks.
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.

Anthropic Data Handling
Overview
Handle data responsibly when building with Claude — manage the 200K token context window efficiently, implement conversation trimming strategies, redact PII before sending to the API, and configure data retention settings.
Context Window Management
Claude models have a 200K token context window. Managing it efficiently is critical.
// Count tokens before sending
const count = await client.messages.countTokens({
model: 'claude-sonnet-4-20250514',
messages,
system: systemPrompt,
});
// Budget: 200K total - max_tokens (output) = available input
const MAX_CONTEXT = 200_000;
const MAX_OUTPUT = 4096;
const inputBudget = MAX_CONTEXT - MAX_OUTPUT;
if (count.input_tokens > inputBudget) {
// Trim oldest messages, keep system prompt + recent context
messages = trimToFit(messages, inputBudget);
}Instructions
Step 1: Conversation Trimming
function trimConversation(messages: MessageParam[], maxTokens: number): MessageParam[] {
// Always keep the first message (often contains key context)
// Keep the most recent messages
// Drop middle turns first
if (messages.length <= 4) return messages;
const first = messages[0];
const recent = messages.slice(-6); // Last 3 turns
return [first, ...recent];
}PII Handling
// Strip PII before sending to Claude (if not needed for the task)
function redactPII(text: string): string {
return text
.replace(/\b[\w._%+-]+@[\w.-]+\.\w{2,}\b/g, '[EMAIL]')
.replace(/\b\d{3}[-.]?\d{3}[-.]?\d{4}\b/g, '[PHONE]')
.replace(/\b\d{3}-\d{2}-\d{4}\b/g, '[SSN]')
.replace(/\b\d{4}[\s-]?\d{4}[\s-]?\d{4}[\s-]?\d{4}\b/g, '[CARD]');
}Data Retention
- Default: Anthropic does not use API data for training
- Zero retention: Available on Enterprise plans
- Your responsibility: Don't store Claude responses containing user PII longer than needed
Output
- Token counting implemented before sending requests (prevents context overflow errors)
- Conversation trimming preserving first message and recent turns
- PII redaction applied for emails, phone numbers, SSNs, and card numbers
- Data retention policy documented and configured
Error Handling
| Error | Cause | Solution |
|---|---|---|
| API Error | Check error type and status code | See clade-common-errors |
Examples
See Context Window Management (token counting + budget), Conversation Trimming function, and PII Handling regex patterns above.
