sql-dynamic-pattern-analyzer

sql-dynamic-pattern-analyzer is a skill for Claude Code from sfc-gh-dflippo/snowflake-dbt-demo. It costs 62 tokens per session (3,369 once invoked), scanned A, original, Apache-2.0.

A migration assessment tool for finding and reviewing dynamic SQL, meaning SQL text assembled while a program runs, in SnowConvert reports. It classifies each occurrence and records its migration concerns for moves to Snowflake.

In plain words
What is it for?
It helps assess SQL Server, Redshift, Oracle, or Teradata workloads before migration to Snowflake, including reviewing dynamic SQL patterns and documenting changes that may be needed.
Why use it?
Dynamic SQL can behave differently after moving between database systems, and its complexity is easy to miss in a large codebase. This tool gives each flagged occurrence a consistent classification and complexity score.

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-dynamic-pattern-analyzer 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Analyzing SQL Dynamic Patterns

Analyzes Dynamic SQL occurrences flagged by SnowConvert (issue code SSC-EWI-0030), classifies them against a dialect-specific pattern catalog, scores complexity, and records migration considerations. All operations go through the scai assessment sql-dynamic command — there are no Python helpers, no CSV/JSON scripts, no bash loops.

Sub-Agent Mode

When invoked from a parent skill (e.g., assessment/SKILL.md) as a sub-agent, the parent provides a context block with the fields below. The review_mode field controls whether the per-occurrence review loop runs.

Field Required Notes
project_dir yes absolute path to the SCAI project root
output_dir yes typically <project_dir>/assessment/json
review_mode yes generate-only, auto-review-all, or skip

On entry: call the configure MCP tool with project_dir from the context block. Snowflake credentials are not required — scai assessment sql-dynamic reads only local CSVs and source files.

Branching by review_mode:

  • generate-only — run only scai assessment sql-dynamic generate (Workflow Step 1) and return. The output JSON will contain PENDING occurrences; that is expected.
  • auto-review-all — generate, then loop show-code-unit → analyze → update --status REVIEWED for every PENDING occurrence (Workflow Steps 2–6). Run stats at the end and confirm zero PENDING. The single-record / unique-analysis rule from Critical Rules (NO BATCH UPDATES) still applies — each occurrence gets its own analysis.
  • skip — return immediately with "status": "skipped". The parent should not have dispatched in this case; this branch is defensive.

On completion, return JSON only:

{
  "sub_skill": "analyzing-sql-dynamic-patterns",
  "status": "ok",
  "output_json": "<abs path to sql_dynamic_analysis.json>",
  "summary": "<one-line: total occurrences, REVIEWED count, PENDING count>",
  "error": null
}

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.
