analytics-with-claude-code: Skill for Claude Code

.claude/skills/metric-reconciler/SKILL.md

metric-reconciler is a skill for Claude Code from adityawrk/analytics-with-claude-code. It costs 57 tokens per session (4,382 once invoked), scanned A, original, MIT.

A method for comparing two definitions of the same metric and locating the exact reason their results differ. A metric is a calculated value such as revenue, users, or conversion rate; dbt is a tool for building data models with SQL.

In plain words
What is it for?
Use it to compare SQL queries, dbt models, dashboard calculations, or all code that defines a named metric, including during a migration.
Why use it?
It replaces a vague mismatch between reports or queries with a precise comparison of their logic and data sources.

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

metric-reconciler 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.

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.

Metric Disagreement Detector

You are a senior analytics engineer specializing in data quality and metric governance. Your job is to take two definitions of what is supposed to be the same metric and determine precisely where and why they produce different results. This is one of the hardest problems in analytics -- metrics that "should be the same" but are not -- and you will solve it methodically.

Step 0: Acquire the Two Metric Definitions

Accept the two metric definitions from any of these sources:

Source Types

  1. Inline SQL: Two queries pasted directly.
  2. File paths: --file1 path/to/query_a.sql --file2 path/to/query_b.sql. Read both files.
  3. dbt model references: --model1 fct_revenue --model2 rpt_revenue. Search for the corresponding .sql files using Glob patterns like **/fct_revenue.sql.
  4. Mixed: One inline query compared against a file or dbt model.
  5. Metric name search: --metric "monthly revenue" -- search the codebase for all queries/models that calculate this metric (look for column aliases like monthly_revenue, revenue_monthly, comments mentioning "monthly revenue", and dbt metric definitions). Present all found definitions and let the user pick two to compare.

Labeling

  • Label the first definition as Query A (or Model A) and the second as Query B (or Model B).
  • If one is considered the "source of truth" (the user says so, or it is from a production dbt model vs. an ad-hoc query), label it as Reference and the other as Candidate.

Validation

  • Confirm both queries are syntactically valid SQL before proceeding.
  • Confirm both queries appear to calculate the same type of metric (e.g., both produce revenue numbers, both produce user counts). If they appear to calculate fundamentally different things, warn the user.

Step 1: Structural Comparison

Perform a side-by-side structural analysis of both queries. For each of the following dimensions, compare Query A and Query B:

metric-reconciler is a skill published in the GitHub repository adityawrk/analytics-with-claude-code (5 stars, last pushed 6mo ago), licensed MIT. It adds 57 tokens to every session and 4,382 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
