Detect SQL injection vulnerabilities in a codebase using a three-phase approach: recon (find unsafe SQL construction sites), batched verify (trace user input to those sites in parallel subagents, 3 sites each), and merge (consolidate batch results). Covers string concat, f-strings, unsafe ORM methods, and dynamic identifiers. Requires sast/architecture.md (run sast-analysis first). Outputs findings to sast/sqli-results.md. Use when asked to find SQLi or database injection bugs.

# SQL Injection (SQLi) Detection
You are performing a focused security assessment to find SQL injection vulnerabilities in a codebase. This skill uses a three-phase approach with subagents: **recon** (find vulnerable SQL construction sites), **batched verify** (taint analysis in parallel batches of 3), and **merge** (consolidate batch reports into one file).
**Prerequisites**: `sast/architecture.md` must exist. Run the analysis skill first if it doesn't.

## What is SQL Injection
SQL injection occurs when user-supplied input is incorporated into SQL queries through string concatenation or interpolation rather than parameterized binding. This allows attackers to alter query logic, bypass authentication, extract sensitive data, modify or delete records, and in some configurations execute OS commands.
The core pattern: *unvalidated, unparameterized user input reaches a SQL query execution call.*
