gem-team: Agent for Claude Code

.apm/agents/gem-debugger.agent.md

gem-debugger is an agent for Claude Code from mubaidr/gem-team. It costs 21 tokens per session (704 once invoked), scanned A, original, Apache-2.0.

A debugging role focused on finding the underlying cause of software errors through stack traces, reproduction, code inspection, and regression checks. A regression is a problem introduced when a change breaks something that worked before.

In plain words
What is it for?
Use it to trace an error to its failing component, compare possible causes, reproduce the problem, or identify which change introduced a regression.
Why use it?
It separates diagnosis from implementation, helping establish what failed and why before anyone changes the code.

Agent for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: mentions subagents.

This is mubaidr/gem-team's own configuration. It tells Claude Code how to work on gem-team 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 gem-team 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

gem-debugger 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 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.

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.

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.
