Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 8 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00085 | $0.03153 |
| Opus 5 | $0.00043 | $0.01577 |
| Sonnet 5 | $0.00017 | $0.00631 |
| Haiku 4.5 | $0.00009 | $0.00315 |
Grade B, and why
conventions-antigravity scanned grade B with 1 finding 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 8d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Antigravity Conventions (with Gemini CLI legacy)
Tool-specific overlay for Google Antigravity CLI artifacts, including legacy Gemini CLI paths during the transition window. Loaded by the scorer and checker when an artifact is classified as Tier 2-Antigravity (per agents/scorer.md step 3). The universal floor lives in nlpm:conventions.
Status: Antigravity 2.0 was announced at Google I/O 2026 on 2026-05-19 (six days before this file was written). The directory layout is still settling, the official Antigravity-specific spec doc is sparse, and two authoritative research passes disagreed on .agent/ (singular) vs .agents/ (plural) as the canonical skills path. This skill is advisory-only for Antigravity-specific artifacts. PR-B verification trigger conditions are recorded in analysis/multi-tool-design-2026-05.md.
Transition timeline:
- Now → 2026-06-18: Gemini CLI continues serving AI Pro / Ultra / Free tiers in parallel with Antigravity CLI.
- 2026-06-18: Gemini CLI sunsets for non-enterprise. Enterprise paid licenses retained.
- After sunset: Antigravity CLI is the sole successor;
.gemini/paths fade to legacy.

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.
- 8d ago First seen · 196 lines · 85 tokens per session scan B 2cf200455368
conventions-antigravity is a skill published in the GitHub repository xiaolai/nlpm (135 stars, last pushed yesterday), licensed ISC. It adds 85 tokens to every session and 3,153 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
