gsd-context

gsd-context is a command for Claude Code from mrboups/xbrain. It costs 14 tokens per session (185 once invoked), scanned A, a copy of gsd-context, MIT.

A command router for understanding a codebase: mapping its structure, querying generated knowledge files, building a knowledge graph, and updating documentation.

In plain words
What is it for?
Use it to inspect an unfamiliar repository, query its mapped information, generate a graph of relationships, update documentation, or record lessons from completed work.
Why use it?
It provides a single way to choose between a quick scan, a full map, targeted questions, and deeper project-knowledge tasks.

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

gsd-context 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 2d 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.

Origin

This is a copy

88% identical to gsd-context — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Route to the appropriate codebase-intelligence skill based on the user's intent. gsd-scan and gsd-intel were folded into gsd-map-codebase flags by #2790.

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.
