Fine to try.

By jgsystemsconsulting/jgs-se-knowledge-packs (GitHub) · coding · 70 stars · scanned at commit 3bf1e13

Knowledge base from IS-GPS-200 Rev N (NAVSTAR GPS Space Segment / Navigation User Segment Interfaces). Use as a worked ICD/IS exemplar: what an interface specification is, DIST-A and IRN/CCB change control, interface definition vs identification, composite-signal criteria patterns, NAV data as payload families, and time/definition hygiene. Covers Rev N synthesized notes only; does not transcribe Apps II–IV bit fields or PRN/Gold-code tables, and does not replace faa-std-025 preparation rules.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'is-gps-200n' ] || [ -L ~/.agents/skills/'is-gps-200n' ]; then echo 'A skill folder named is-gps-200n already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jgsystemsconsulting/jgs-se-knowledge-packs' "$d" && git -C "$d" checkout --quiet '3bf1e1338acf4cb83e9339ce535228635165f288' -- 'packs/is-gps-200n' && mkdir -p ~/.agents/skills && cp -R "$d"/'packs/is-gps-200n' ~/.agents/skills/'is-gps-200n' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'is-gps-200n' ~/.claude/skills/'is-gps-200n' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
