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 | $0.09408 | $0.09408 |
| Opus 5 | $0.04704 | $0.04704 |
| Sonnet 5 | $0.01882 | $0.01882 |
| Haiku 4.5 | $0.00941 | $0.00941 |
Grade A, and why
applications AGENTS.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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 1,205 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent.md — Python + uv
Purpose
- This repository uses Python managed by uv for dependency resolution, virtual environments, locking, and execution. Always prefer uv subcommands (add/remove/run/sync/export) over raw pip/venv commands.
Core rules
- Use
uv addto add or upgrade dependencies so that bothpyproject.tomlanduv.lockstay in sync; do not usepip installdirectly. - Keep runtime dependencies in
[project.dependencies]and development-only tools in thedevgroup viauv add --dev .... - Use
uv runto execute Python, test, and tooling commands without manually activating a virtual environment.
Project bootstrap
- New project (scaffold files):
uv init - First install or clean install:
uv sync - Run the app:
uv run python -m <your_module>oruv run main.py - REPL:
uv run python - Scripts in pyproject: prefer
uv run <command>to ensure the correct environment is used
Managing dependencies
- Add runtime dependency:
uv add <name>(e.g.,uv add httpx) - Add dev dependencies:
uv add --dev pytest ruff - Pin/upgrade by constraint:
uv add "httpx>=0.27"or adjustpyproject.tomland thenuv sync - Remove dependency:
uv remove <name> - Export lock for external tooling:
uv export --format requirements-txt --output-file requirements.txt
Locking and environments
uv runanduv syncwill ensure the environment matchespyproject.tomlanduv.lock- Avoid manual
pip installor manualvenvactivation; let uv manage the environment - Commit
uv.lockto version control for reproducible installs
pyproject guidance
- Dependencies live under
[project]→dependencies = [...] - Development-only tooling should go under a dev group (e.g.,
uv add --dev ruff pytest) for clean separation - Keep
requires-pythoncurrent (e.g.,>=3.12) to match the team’s baseline
Usage in this repo
- When adding libraries or changing versions, propose
uv add ...changes that update bothpyproject.tomlanduv.lock, then runuv run pytest -qto validate - Prefer minimal diffs, explain the plan, apply changes, and run tests/tooling via
uv run - If build/test fails, inspect error context, adjust constraints or code, and re-run via
uv run
Common commands (copy/paste)
- Initialize:
uv init| Install deps:uv sync - Add runtime:
uv add <pkg>| Add dev:uv add --dev <pkg> - Remove:
uv remove <pkg> - Run app:
uv run python -m <your_module>oruv run main.py - Tests:
uv run pytest -q - Lint/format:
uv run ruff check .and/oruv run ruff format . - Export:
uv export --format requirements-txt --output-file requirements.txt
Of course. Based on your request and the example app.py you provided, here is a new section that you can append to your gemini.md file. This section provides clear guidance on how to write effective tool names and descriptions, using the Perplexity chat function as a concrete example.
The proposed changes will make the function's purpose much clearer, especially its ability to access and cite real-time web information, which is a key feature.
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.

applications AGENTS.md is an instructions file published in the GitHub repository universal-mcp/applications (2 stars, last pushed 4mo ago), licensed MIT. It adds 9,408 tokens to every session, about $0.0470 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.
