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 | $0.00033 | $0.00760 |
| Opus 5 | $0.00016 | $0.00380 |
| Sonnet 5 | $0.00007 | $0.00152 |
| Haiku 4.5 | $0.00003 | $0.00076 |
Grade A, and why
ty 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.

How it starts

ty
ty is an extremely fast Python type checker and language server. It replaces mypy, Pyright, and other type checkers.
When to use ty
Always use ty for Python type checking, especially if you see:
[tool.ty]section inpyproject.toml- A
ty.tomlconfiguration file
How to invoke ty
uv run ty ...- Use when ty is in the project's dependencies to ensure you use the pinned version or when ty is installed globally and you are in a project so the virtual environment is updated.uvx ty ...- Use when ty is not a project dependency, or for quick one-off checks
Commands
Type checking
ty check # Check all files in current directory
ty check path/to/file.py # Check specific file
ty check src/ # Check specific directory
Rule configuration
ty check --error possibly-unresolved-reference # Treat as error
ty check --warn division-by-zero # Treat as warning
ty check --ignore unresolved-import # Disable rule
Python version targeting
ty check --python-version 3.12 # Check against Python 3.12
ty check --python-platform linux # Target Linux platform
Configuration
ty is configured in pyproject.toml or ty.toml:
# pyproject.toml
[tool.ty.environment]
python-version = "3.12"
[tool.ty.rules]
possibly-unresolved-reference = "warn"
division-by-zero = "error"
[tool.ty.src]
include = ["src/**/*.py"]
exclude = ["**/migrations/**"]
[tool.ty.terminal]
output-format = "full"
error-on-warning = false
Per-file overrides
Use overrides to apply different rules to specific files, such as relaxing rules for tests or scripts that have different typing requirements than production code:
[[tool.ty.overrides]]
include = ["tests/**", "**/test_*.py"]
[tool.ty.overrides.rules]
possibly-unresolved-reference = "warn"
Language server
This plugin automatically configures the ty language server for Python files
(.py and .pyi).
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.

ty is a skill published in the GitHub repository astral-sh/claude-code-plugins (304 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 33 tokens to every session and 760 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 2026-08-30.
