codesage

A Claude Code integration that gives one shared coding assistant access to semantic search, code structure, change-impact analysis, and exported project context across connected projects.

In plain words
What is it for?
It is for onboarding projects, resetting or rebuilding their indexes, benchmarking code retrieval, and reviewing feature slices—mapped parts of a codebase—with supporting subagents.
Why use it?
It helps locate relevant code and understand how changes may affect a project without relying only on text searches. It also provides commands for keeping its project map current and checking retrieval quality.

Security

Grade A, and why

codesage 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.

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.
