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.

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 | $0.00038 | $0.00350 |
| Opus 5 | $0.00019 | $0.00175 |
| Sonnet 5 | $0.00008 | $0.00070 |
| Haiku 4.5 | $0.00004 | $0.00035 |
Grade A, and why
agy-customizations 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 9d 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.
What it actually says
Antigravity Customization System
This skill explains how customizations work within Antigravity (AGY), their discovery mechanisms, loading priorities, and best practices for creating skills, rules, plugins, and MCP servers.
When to Use
- Writing new custom skills for Antigravity workspaces.
- Adding repository rules (
.agent/rules/*.mdorAGENTS.md). - Configuring Model Context Protocol (MCP) servers (
~/.gemini/antigravity-cli/mcp/). - Building lifecycle hooks and terminal integration extensions.
Discovery & Loading Priority
Customizations are discovered and merged in the following order of precedence (highest to lowest):
- Workspace Local:
<workspace_root>/.agent/skills/ - Global User:
~/.gemini/antigravity-cli/skills/ - Built-in System:
antigravity-cli/builtin/skills/
Authoring Canonical SKILL.md
Every skill must have a root SKILL.md with standard YAML frontmatter with name and description.
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.

agy-customizations is a skill published in the GitHub repository pedroiff0/awesome-skills (1 stars, last pushed 2d ago), licensed MIT. It adds 38 tokens to every session and 350 once invoked, about $0.0002 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 2026-08-31.

dx-roaster
Brutally honest developer-experience audit for a GitHub repo. Scores 10 DX dimensions (time-to-first-success, README clarity, visual proof, install, quick-start, docs, examples, community, trust, marketing), writes a shareable roast in the requested tone (brutal/honest/kind), produces a prioritized action plan ranked…
mnemosyne-maintenance
Use when: upgrading Mnemosyne, diagnosing slow/hung consolidation (mnemosynesleep), fixing missing embeddings, or troubleshooting import/version mismatches.
review-workflow
A review workflow for GitHub pull requests and issues, including judging whether changes can be merged or an issue can be closed. It requires read-only review, REST API access, and testing changes in practice.
specification-compliance-review
Use this skill when an implementation is described as partial, passing, or complete and the task is to determine whether it actually satisfies an explicit specification. This is not a generic code review and not a re-run of the test suite. The central question is: does every normative requirement have both a correct…
dsh-requesting-code-review
A pre-commit code review process with separate checks for general quality and for matching the requested specification. A commit is a saved set of code changes in Git.
github-code-review
Perform code reviews on local changes before pushing, or review open PRs on GitHub. Most of this skill uses plain git — the gh/curl split only matters for PR-level interactions.
