Radar #15

Sep 28 – Oct 4, 2026 · Published Sep 28, 2026, 5:58 PM UTC

Fleet snapshot

Anonymous counts across all complete scans this week. No repository names are shown.

496 repositories were scanned for AI-context hygiene.

3668 AI-context risk signals matched 28 sensitive path categories.

0% of scanned repos use a dedicated AI exclude file (1 type 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

29% of scanned repos had AI-context risk signals — mostly credential and config path categories.

Far fewer repos use a dedicated AI exclude file (0%) than show risk signals (29%). Start by excluding npm credentials (.npmrc) and Environment files (.env) from AI context.

AI exclude files

0% of repos use a dedicated AI exclude file

These actually keep matching files out of AI context — and they are still rare.

AI context files

28% 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), Private keys (.key), Certificates and PEM keys (.pem)). Add them to a dedicated AI exclude file (for example .cursorignore or.claudeignore) — and to .gitignore so the files are never committed.

Per-category guidance lives in the risk pattern guides.
