validating-aws-pricing

validating-aws-pricing is a skill for Claude Code from prajapatimehul/claude-aws-cost-saver. It costs 78 tokens per session (2,464 once invoked), scanned A, original, MIT.

A required validator for AWS cost findings that checks monthly savings estimates against AWS pricing and billing data.

In plain words
What is it for?
Use it on findings.json before generating a report to validate pricing sources and reject estimates that cannot be verified.
Why use it?
It catches incorrect prices, formulas, missing cost components, and savings claims that exceed actual spending.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

validating-aws-pricing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate_pricing.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 280 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Validating AWS Pricing

MANDATORY validation step that catches pricing errors before they reach the user.

Why This Matters

Common errors this skill catches:

  • CloudWatch Logs: Confusing $0.50/GB ingestion with $0.03/GB storage
  • Savings exceeding actual service spend (impossible)
  • Wrong multipliers or formulas
  • Missing cost components

Purpose

This skill validates pricing for ALL findings using the Zero Hallucination Pricing System. Every finding must have a verifiable pricing_source. Findings without a pricing source or with fabricated prices are rejected (set to monthly_savings=0 with pricing_unknown=true).

Quick Start

# Validate with default $100 threshold (queries API only for >$100 findings)
python3 "${CLAUDE_PLUGIN_ROOT}/skills/validating-aws-pricing/scripts/validate_pricing.py" findings.json --profile your-profile

# Lower threshold to validate more findings
python3 "${CLAUDE_PLUGIN_ROOT}/skills/validating-aws-pricing/scripts/validate_pricing.py" findings.json --profile your-profile --threshold 50

# Works with any AWS auth method (SSO, access keys, IAM role)
python3 "${CLAUDE_PLUGIN_ROOT}/skills/validating-aws-pricing/scripts/validate_pricing.py" findings.json  # uses default credentials

What Gets Updated

For findings above threshold (default $100):

  1. Queries real AWS Pricing API for EC2, RDS, EBS
  2. Updates monthly_savings with validated value
  3. Marks api_validated: true in metadata

For findings below threshold:

  1. Preserves pricing that already carries a compliant pricing_source and calculation
  2. Resolves from the verified us-east-1 table where an exact formula exists
  3. Otherwise sets monthly_savings=0 with pricing_unknown=true — it NEVER estimates

All findings get pricing_validated metadata showing the source.

Pricing Calculation by Finding Type

Idle Resources (EC2-001, etc.)

Savings = Full monthly cost of the resource

savings = hourly_rate * 730  # Resource should be terminated

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
