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 | $0.01091 | $0.01091 |
| Opus 5 | $0.00545 | $0.00545 |
| Sonnet 5 | $0.00218 | $0.00218 |
| Haiku 4.5 | $0.00109 | $0.00109 |
Grade A, and why
oastools GEMINI.md 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 2d 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.

This document provides a comprehensive overview of the oastools project, designed to facilitate understanding and contribution for Gemini agents.
Project Overview
oastools is a Go-based command-line interface (CLI) and library for working with OpenAPI specifications (OAS). It provides a rich set of features for parsing, validating, converting, diffing, joining, and building OAS documents, as well as generating Go code from them. The project supports all OpenAPI versions from 2.0 to 3.2.0.
The project is structured as a Go module with several public packages, each corresponding to a major feature:
parser: For parsing and analyzing OpenAPI specifications.validator: For validating the correctness of OpenAPI specifications.fixer: For automatically fixing common validation errors in OpenAPI specifications.converter: For converting between different OpenAPI versions (e.g., 2.0 to 3.x).joiner: For merging multiple OpenAPI specifications.differ: For comparing OpenAPI specifications and detecting breaking changes.generator: For generating idiomatic Go code (clients, servers, types) from OpenAPI specifications.builder: For programmatically constructing OpenAPI specifications.
The project also includes a CLI tool, oastools, which exposes the library's functionality on the command line.
Building and Running
The project uses a Makefile to streamline common development tasks.
Key Commands
-
Build the CLI:
make buildThis command compiles the
oastoolsCLI and places the binary in thebin/directory. -
Run tests:
make testThis command runs the test suite for all packages.
-
Run tests with race detection:
make test-race -
Generate a test coverage report:
make test-coverageThis will generate an HTML coverage report named
coverage.html. -
Lint the code:
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.

oastools GEMINI.md is an instructions file published in the GitHub repository erraggy/oastools (5 stars, last pushed 4d ago), licensed MIT. It adds 1,091 tokens to every session, about $0.0055 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.
