gsd-codebase-mapper

gsd-codebase-mapper is an agent for Claude Code from JHamidun/claude-code-config-pack. It costs 46 tokens per session (4,379 once invoked), scanned C, original, no licence file.

An agent that explores a codebase and writes structured analysis documents about a chosen area, such as technology, architecture, quality, or concerns.

In plain words
What is it for?
It is for mapping a repository's technology choices, architecture, quality issues, and concerns, then writing the findings directly into analysis documents.
Why use it?
It turns codebase exploration into saved notes, reducing the amount of investigation the coordinating agent must keep in working memory.

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 C, and why

gsd-codebase-mapper scanned grade C 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 6d 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.

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

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 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.
