What it does
Clade Cost Tuning is an agent skill from jeremylongshore/tons-of-skills-marketplace. Optimize Anthropic API costs — model selection, prompt caching, batches, Use when working with cost-tuning patterns. token reduction, and usage monitoring. Trigger with "anthropic pricing", "claude cost", "reduce anthropic spend", "anthropic billing", "claude cheaper".
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/one-pager.md`). Compatibility notes: Designed for Claude Code
It sits in AI & LLM Engineering, covering LLM cost and token optimization. It works with Anthropic API. 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
- Working with cost-tuning patterns
- With anthropic pricing
- Reduce anthropic spend
- Anthropic billing
Example prompts
- “anthropic pricing”
- “claude cost”
- “reduce anthropic spend”
- “/clade-cost-tuning”
Requirements
- Compatibility (from SKILL.md): Designed for Claude Code
- Pre-approved tools (allowed-tools): Read, Write, Edit
Workflow steps
5 steps, taken from the step headings in SKILL.md.
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.comanthropic.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 Cost Tuning loads about 1.3k tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 257 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 Cost Tuning
Overview
Anthropic charges per token. Input tokens, output tokens, and cached tokens each have different prices. Here's how to minimize cost without losing quality.
Pricing (per million tokens)
| Model | Input | Output | Cached Input | Batch Input | Batch Output |
|---|---|---|---|---|---|
| Claude Opus 4 | $15.00 | $75.00 | $1.50 | $7.50 | $37.50 |
| Claude Sonnet 4 | $3.00 | $15.00 | $0.30 | $1.50 | $7.50 |
| Claude Haiku 4.5 | $0.80 | $4.00 | $0.08 | $0.40 | $2.00 |
Cost Reduction Strategies
Instructions
Step 1: Right-Size Your Model
// DON'T use Opus for everything
// DO match model to task complexity:
// Simple classification/extraction → Haiku (cheapest)
const category = await classify(text, 'claude-haiku-4-5-20251001');
// General coding/writing → Sonnet (balanced)
const code = await generate(spec, 'claude-sonnet-4-20250514');
// Complex multi-step reasoning → Opus (best quality)
const analysis = await analyze(data, 'claude-opus-4-20250514');Step 2: Prompt Caching (90% off input tokens)
// Cache your system prompt — pays for itself after 2 calls
const message = await client.messages.create({
model: 'claude-sonnet-4-20250514',
max_tokens: 1024,
system: [{
type: 'text',
text: longSystemPrompt, // Must be 1024+ tokens
cache_control: { type: 'ephemeral' }, // Cache for 5 minutes
}],
messages,
}, {
headers: { 'claude-beta': 'prompt-caching-2024-07-31' },
});
// First call: cache_creation_input_tokens charged at 1.25x
// Subsequent calls: cache_read_input_tokens charged at 0.1x (90% savings!)Step 3: Message Batches (50% off everything)
// For non-urgent work — 50% cheaper, 24h processing SLA
const batch = await client.messages.batches.create({
requests: prompts.map((p, i) => ({
custom_id: `job-${i}`,
params: {
model: 'claude-sonnet-4-20250514',
max_tokens: 1024,
messages: [{ role: 'user', content: p }],
},
})),
});
// Sonnet: $1.50/$7.50 per MTok instead of $3/$15Step 4: Reduce Token Count
// Trim conversation history — keep system + last N turns
function trimMessages(messages: MessageParam[], maxTurns = 10) {
if (messages.length <= maxTurns * 2) return messages;
return messages.slice(-(maxTurns * 2));
}
// Set tight max_tokens — don't pay for output you won't use
const message = await client.messages.create({
model: 'claude-sonnet-4-20250514',
max_tokens: 256, // Not 4096 if you only need a short answer
messages,
});
// Use concise system prompts
system: 'Reply in 1-2 sentences.' // Not a 500-word personality descriptionStep 5: Monitor Usage
// Log every call's cost
function logUsage(message: Anthropic.Message) {
const { input_tokens, output_tokens } = message.usage;
const cost = (input_tokens * 3 + output_tokens * 15) / 1_000_000; // Sonnet pricing
console.log(`Tokens: ${input_tokens}in/${output_tokens}out | Cost: $${cost.toFixed(4)}`);
}Cost Comparison Example
Processing 10,000 documents (avg 500 tokens each, 200 token response):
| Strategy | Input Cost | Output Cost | Total |
|---|---|---|---|
| Opus, no optimization | $75.00 | $150.00 | $225.00 |
| Sonnet, no optimization | $15.00 | $30.00 | $45.00 |
| Sonnet + Batches | $7.50 | $15.00 | $22.50 |
| Haiku + Batches | $2.00 | $4.00 | $6.00 |
| Haiku + Batches + Caching | ~$1.00 | $4.00 | ~$5.00 |
Output
- Model selection optimized per task complexity (Haiku for simple, Sonnet for balanced, Opus for complex)
- Prompt caching enabled for repeated system prompts
- Batch processing configured for non-urgent workloads
- Token usage logged with cost estimates per request
- Spending alerts configured in Anthropic console
Error Handling
| Error | Cause | Solution |
|---|---|---|
| API Error | Check error type and status code | See clade-common-errors |
Examples
See Pricing table, five numbered strategy sections with code, and the Cost Comparison Example table showing savings from $225 to $5 for 10K documents.
