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 | $0.00045 | $0.00464 |
| Opus 5.5 | $0.00018 | $0.00186 |
| Sonnet 5.5 | $0.00009 | $0.00093 |
| Haiku 4.5 | $0.00005 | $0.00046 |
Grade A, and why
python-stack 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 today.
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
Python Stack
Maintain a small typed Python foundation and choose libraries for demonstrated requirements. Preserve the existing environment and conventions rather than restarting a scaffold for every feature.
Workflow
Read only the matching guide and its required resources. Dataframe code in any profile, scripts included, defaults to Polars.
Task guides
- api-client: Build typed Python HTTPX API clients with bounded pagination and retries.
- foundation: Python package layout, dependency choices, defaults, and project scaffolding.
- langextract: Extract structured facts from text with LangExtract and source-grounded evidence.
- observability: Instrument Python services and agents: structlog logs, OpenTelemetry traces and metrics.
- pydantic: Typed validation, serialization, and settings boundaries.
- python-async: Async design, cancellation, timeouts, and shutdown.
- python-script: Standalone single-file utilities with PEP 723 inline metadata run by uv run --script.
- python-testing: Write Python tests with pytest, fixtures, property tests, and TDD.
- ruff: Python linting, formatting, imports, and safe fixes.
- ty: Type diagnostics and environment resolution.
- uv: Dependency resolution, environments, packaging, and lockfiles.

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.

python-stack is a skill published in the GitHub repository fmind/dot (12 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 464 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
Other skills, from other repositories
python-stack
Build typed Python projects with uv, Ruff, ty, pytest, Litestar, and Typer. Use for packages, CLIs, web apps, tests, typing, or API verification.
python-script
Write standalone single-file Python scripts using PEP 723 inline metadata and uv. Use when creating a quick CLI script that needs dependencies without a full project.
scaffold-python
Scaffold a complete Python project with CI/CD, release pipeline, justfile, sr.yaml, pyproject.toml, .envrc, and standard files. Uses uv, ruff, and justfile (Python lacks a native task runner like pnpm scripts, so just fills that gap). Loads on top of scaffold-project (run that first for cross-language standard files).…
go-stack
Build Go projects, libraries, CLIs, TUIs, web apps, or ADK agents with the standard package layout and pinned tooling.
aiohttp
Use when building Python async HTTP services or clients with aiohttp - web server routing, middleware, WebSocket, SSE, streaming, client sessions, pytest-aiohttp testing, or troubleshooting SSL and timeout issues.
django-celery
Use when integrating Celery with Django - task definition and calling, django-celery-beat scheduling, worker deployment, Flower monitoring, testing tasks, batch processing, or choosing between cron and beat.
