Radar #18
Oct 19–25, 2026 · Published Oct 20, 2026, 6:09 AM UTC
Fleet snapshot
Anonymous counts across all complete scans this week. No repository names are shown.
492 repositories were scanned for AI-context hygiene.
761 AI-context risk signals matched 22 sensitive path categories.
1% of scanned repos use a dedicated AI exclude file (3 types in use).
How to read this report
These are not confirmed leaks.
Radar uses path-level checks to detect files and folders that may become visible to AI coding tools if they are not covered by AI-specific ignore rules.
A risk signal is a file committed to the repository whose path matches a sensitive category (for example .env or *.pem). Counts are file matches at the path level — Radar never opens the files.
- No file contents were read.
- No secrets were collected.
- No repository names are published without opt-in.
- Repositories are a manually curated cohort, not a random sample — read these as directional signals, not population-level statistics.

Main takeaway
31% of scanned repos had AI-context risk signals — mostly secret and signing path categories.
Far fewer repos use a dedicated AI exclude file (1%) than show risk signals (31%). Start by excluding Environment files (.env) and npm credentials (.npmrc) from AI context.

AI exclude files
1% of repos use a dedicated AI exclude file
These actually keep matching files out of AI context — and they are still rare.
Show 9 more exclude file types (3 in use overall)
AI context files
26% of repos ship an AI context file
Files like AGENTS.md and CLAUDE.md give AI tools project instructions — theyadd context, they do not exclude anything. They are not a substitute for an exclude file.
Fix the top risks
Patterns covering this week's most widespread categories (Environment files (.env), npm credentials (.npmrc), Certificates and PEM keys (.pem), Private keys (.key)). Add them to a dedicated AI exclude file (for example .cursorignore or.claudeignore) — and to .gitignore so the files are never committed.
