sql-server-table-reconciliation

sql-server-table-reconciliation is a skill for Claude Code, Codex from OKHP3/skillz. It costs 56 tokens per session (1,404 once invoked), scanned A, a copy of sql-server-table-reconciliation, MIT.

A tool for comparing matching tables across two SQL Server databases, such as production and staging. It checks rows, columns, and schema differences and produces a reconciliation report.

In plain words
What is it for?
Use it to compare selected tables, detect missing rows and column mismatches, find schema drift, and validate data transfers using SQL or Azure identity authentication.
Why use it?
It helps verify data migrations and ETL jobs by showing what is missing, different, or structurally inconsistent between the two systems.

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

sql-server-table-reconciliation 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/reconcile.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.

SQL Server Table Reconciliation

Compare identical tables across two SQL Server instances using Python with mssql-python driver and Apache Arrow. Detect missing rows, column mismatches, schema drift, and produce a reconciliation report.

Workflow

  1. Collect connection details for source and target
  2. Identify primary key / composite key
  3. Detect schema differences
  4. Extract data via Arrow for efficient columnar transfer
  5. Compare rows and columns
  6. Generate reconciliation report

Collect Inputs

Parameter Required Description
Source server Yes Source SQL Server (e.g. prod-server.database.windows.net)
Source database Yes Source database name
Target server Yes Target SQL Server (e.g. staging-server.database.windows.net)
Target database Yes Target database name
Tables Yes Comma-separated schema.table names, or schema.* wildcard (e.g. dbo.Orders,dbo.Items or dbo.*)
Auth mode Yes sql (user/password) or entra (Azure AD/token)
Primary key Auto-detect Column(s) forming the row identity. Auto-detect from metadata if not provided.
Columns to compare All Subset of columns, or all non-PK columns
Chunk size 100000 Rows per batch for large tables
Output format console console, csv, parquet, or json

Bundled Script

The reconciliation logic is provided as a standalone script at scripts/reconcile.py. Invoke it with the appropriate arguments based on user inputs:

python scripts/reconcile.py \
    --source-server <source_server> \
    --source-database <source_database> \
    --target-server <target_server> \
    --target-database <target_database> \
    --tables "<table_spec>" \
    --auth <sql|entra> \
    --chunk-size <chunk_size> \
    --output <console|csv|json>

Optional arguments

Argument Description
--primary-key Comma-separated PK column(s). Omit to auto-detect.
--columns Comma-separated columns to compare. Omit to compare all non-PK columns.

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.
