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.

What it costs to keep this loaded
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 | $0.00057 | $0.00381 |
| Opus 5.5 | $0.00023 | $0.00152 |
| Sonnet 5.5 | $0.00011 | $0.00076 |
| Haiku 4.5 | $0.00006 | $0.00038 |
Grade A, and why
maintain-python-template 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 1mo 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
Maintain Python Template
Make catalog-driven changes without creating a choice that renders but cannot run.
Change Workflow
- Inspect
catalog/components.yml,catalog/presets.yml,copier.yml, the relevant files undertemplate/, and existing tests before editing. - Define the component metadata and compatibility constraints in the catalog first. Keep each choice in exactly one architectural role unless it genuinely serves several roles.
- Wire Copier defaults and choices to the catalog. Preserve the three simple presets and reject incompatible combinations with an actionable validator message.
- Add functional source, dependency, configuration, test, README, and environment-variable templates for the component. Avoid placeholder-only integrations.
- Run
uv run python scripts/compile_catalog.py --check. If generated files are stale, run the command without--check, review all generated changes, then check again. - Add focused repository tests and generate at least one representative project. Validate its imports or endpoints, not only file presence.
- Run the gates in
validate-python-stackbefore proposing delivery.
Invariants
catalog/generated/catalog.json,catalog/generated/choices.yml, anddocs/reference/*.mdare compiler outputs; edit their sources instead.- Generated projects use a
srclayout,uv, Ruff, pytest, typing, and reproducible dependency bounds. - Optional layers must disappear cleanly when disabled.
- Conditional template path components must remain short enough to render on Windows.
- A deploy target keeps Docker portability; cloud IaC is limited to supported target/provider pairs.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

maintain-python-template is a skill published in the GitHub repository leynier/python-template (37 stars, last pushed 15d ago), licensed MIT. It adds 57 tokens to every session and 381 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 2026-08-30.
Other skills, from other repositories
alembic-migration
Create, review, and apply database schema changes with Alembic. Use whenever a SQLAlchemy model is added or changed, a column/index/constraint needs to change, or a data backfill is required — anything that alters the PostgreSQL schema.
pytest-suite
Write or extend the backend test suite following this project's conventions. Use when adding tests for a new service/route/repository, when coverage is missing, or when asked to test a feature. Knows the mocked-session + httpx AsyncClient setup so tests run with no database.
pydantic-resolve-3step
A three-stage development method for Python projects built with pydantic-resolve, starting with agreed data models and ending with application interfaces. It uses an ER diagram, which shows database entities and their relationships, plus ORM models that represent database records in code.
backend-dev-guidelines
Backend development guidelines for Node.js/Express/TypeScript applications. Layered architecture (Routes → Controllers → Services → Repositories), error handling, validation, middleware patterns, database access, and testing. Use when creating routes, endpoints, APIs, controllers, services, repositories, middleware…
pytest
Skill "pytest" from bobmatnyc/claude-mpm-skills, covering pytest - professional python testing, basic pytest, with common plugins, for fastapi testing and for django testing.
add-vertical
Use this skill when adding a new feature vertical to this template — a domain aggregate with its port, repository, application service, DTOs, endpoint, and tests. Trigger it for requests like "add an endpoint", "add a new entity", "build the X feature", or "wire up a new service".
