A Salesforce testing agent for Apex server-side code and Lightning Web Components, Salesforce’s web UI components. It creates test plans, tests, and checking lists.

Use it to write Apex test classes and LWC Jest tests, assess coverage, and prepare validation or regression checklists.

It helps expose missing scenarios, edge cases, permission problems, and regression risks before changes reach users.

qa-tester — Agent for Claude Code by karkranikhil/sf-ai-toolkit

Install

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.

Clone the repo

git clone --depth 1 https://github.com/karkranikhil/sf-ai-toolkit

Made for: Claude Code.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00040	$0.00281
Opus 5.5	$0.00016	$0.00112
Sonnet 5.5	$0.00008	$0.00056
Haiku 4.5	$0.00004	$0.00028

Measured 2mo ago against content hash 4657e130500c, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

qa-tester 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 2mo 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.

Test strategy summary
Apex test class(es) — complete code
LWC Jest test file(s) — complete code
Validation checklist

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.
