gaal: Agent for Claude Code

.github/agents/test-writer.md

TestWriter is an agent for Claude Code from getgaal/gaal. It costs 55 tokens per session (812 once invoked), scanned A, original, AGPL-3.0.

A coding helper that writes unit tests for newly implemented or modified Go functions. It uses table-driven tests and aims for at least 90% coverage of changed code.

In plain words
What is it for?
Use it after changing Go code when you need unit tests covering the affected functions and files.
Why use it?
It helps verify Go changes systematically and makes it easier to spot regressions in the functions you edited.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

This is getgaal/gaal's own configuration. It tells Claude Code how to work on gaal itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything gaal configures →

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

TestWriter 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.

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.
