detecting-sql-injection-vulnerabilities

detecting-sql-injection-vulnerabilities is a skill for Claude Code, Codex from withcrux/agentHack-skills. It costs 49 tokens per session (1,930 once invoked), scanned B, original, no licence file.

A security-testing guide for finding SQL injection, a flaw where crafted input changes a database query in a web application. It uses manual test inputs and automated scans in isolated lab environments.

In plain words
What is it for?
It is for checking error-based, boolean-based, and time-based blind SQL injection in web application inputs.
Why use it?
It helps identify whether web form or request inputs can be misused to access or alter database data. Testing in an isolated lab reduces the risk of affecting real 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 B, and why

detecting-sql-injection-vulnerabilities scanned grade B with 2 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 8d 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.

Harvests environment variablesmediumData exfiltration

Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

id=1 UNION SELECT username,password,3 FROM users-- # Extract credentials

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

detecting-sql-injection-vulnerabilities is a skill published in the GitHub repository withcrux/agentHack-skills (5 stars, last pushed 5mo ago), with no licence file. It adds 49 tokens to every session and 1,930 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (harvests environment variables, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
