SkillSpector: 5 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 →
- high Rogue Agent · line 24 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

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 | $0.00072 | $0.01864 |
| Opus 5 | $0.00036 | $0.00932 |
| Sonnet 5 | $0.00014 | $0.00373 |
| Haiku 4.5 | $0.00007 | $0.00186 |
Grade A, and why
provider-gemini 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 5d 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.

The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Provider: Google Antigravity CLI
Process guidance for keeping the gateway's Gemini-compatible provider key
(gemini) aligned with Google Antigravity CLI (agy). This skill does not
define argv/env behaviour; the single mechanical source of truth is
UPSTREAM_CLI_CONTRACTS.gemini in src/upstream-contracts.ts, enforced by
validateUpstreamCliArgs / validateUpstreamCliEnv. Never re-encode flags,
permission modes, output formats, or resume rules here or in TOML.

These values mirror UPSTREAM_CLI_CONTRACTS.gemini.upstreamMetadata and
docs/upstream/provider-sources.dag.toml ([providers.gemini]). The TypeScript
metadata is authoritative; the TOML is scanner input only.
When to use
- A Google Antigravity CLI release lands and you need to check for contract drift.
- A
geminirequest fails the upstream contract check before spawn. npm run upstream:scan -- --livereports a change on either Antigravity source.
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.

provider-gemini is a skill published in the GitHub repository verivus-oss/llm-cli-gateway (15 stars, last pushed yesterday), licensed MIT. It adds 72 tokens to every session and 1,864 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
