injection-tester

An injection-testing agent for SQL injection, NoSQL injection, and operating-system command injection. These attacks add unintended commands or database queries through application input.

In plain words
What is it for?
Use it to test SQL and NoSQL inputs, probe command-injection paths with curl, and run automated SQL injection checks with sqlmap.
Why use it?
It helps detect whether user-controlled input can alter database queries or execute system commands.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Or install pentest, the plugin that ships this one along with the rest of its 1 skill, 12 agents.

Per session 40 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 637 The whole file, excluding the scripts and references it only reads on demand.

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

injection-tester scanned grade A with 1 finding 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 3d 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.

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

description: Tests SQLi, NoSQLi, and OS command injection. Uses sqlmap for automated SQLi detection and curl for manual probing. 4-phase workflow with approval gate.

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.

injection-tester is an agent published in the GitHub repository humaidhahm/opencode-pentester (23 stars, last pushed 7d ago), with no licence file. It adds 40 tokens to every session and 637 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
